It’s been a particularly busy and colourful week, scam-wise in our household. Between 4 family members, we’ve received almost 20 texts or emails that we’ve identified as scams. And the range was vast: from poorly written emails offering ‘must have’ shopping deals to terse text messages reprimanding us for overdue tolls plus the classic ‘Dear mum, I’ve smashed my phone’ and everything in between.
There’s no doubt that scammers are dedicated opportunists who can pivot fast. They can pose as health authorities during a pandemic, charities after a flood or even your next big love on an online dating platform. And it’s this chameleon ability that means we need to always be on red alert!
According to the Australian Competition and Consumer Commission (ACCC), Aussies lost a record amount of more than $2 billion in scams in 2021. And that was with record levels of intervention from the government, law enforcement agencies and the private sector. The most lucrative scams were investment scams ($701 million) followed by payment redirection scams ($227 million) and then romance scams which netted a whopping $142 million.
But the psychological trauma that is often experienced by victims can be equally as devastating. Many individuals will require extensive counselling and support in order to move on from the emotional scarring from being a victim of hacking.
So, with scammers putting so much energy into trying to lure us into their web, how can we stay one step ahead of these online schemers and ensure we don’t become a victim?
While there are no guarantees in life, there are a few steps you can take so that you can quickly recognise an online scam.
If you’ve received a text message, email or call that you think is a scam, don’t respond. Take your time. Slow down and pause. If it’s a call, and you’re not sure – hang up! Or if it’s a text or email – delete it! But if you are concerned that it might be legitimate, call the company directly using the contact information from their official website or through their secure apps.
If you are being asked to share your personal information or pay money either via a text or phone call, take some time to think. Does it feel legitimate? Do you have a relationship with this organisation? Remember, scammers are very talented at pretending they are from organisations you know and trust. If in doubt, contact the company directly via their official communication channels. Or ask a trusted friend or family member for their input. But remember, NEVER click on any links in messages from people or organisations you don’t know – no exceptions!!
Do not hesitate to take action if something feels wrong. If there are any transactions on your credit card or bank statements that don’t look right, call your bank immediately. If you think you may have given personal information to scammers, then act fast. I recommend calling ID Care – Australia and New Zealand’s national identity and cyber support service. They are a not-for-profit charity that provides support to individuals affected by identity and cyber security issues.
ReportCyber is another way of notifying authorities of a scam. An initiative of the Australian Government and the Australian Cyber Security Centre, it helps authorities investigate and shut down scams. It’s also a good idea to report the scam to Scamwatch – the dedicated scam arm of the Australian Competition and Consumer Commission (ACCC).
We’ve all heard that ‘prevention is better than a cure’ so taking some time to protect yourself before a scammer comes your way is a no-brainer. Here are my top 5 things to do:
Please don’t think smart people don’t get caught up in scams because they do!! Scammers are very adept at looking legitimate and creating a sense of urgency. With many of us living busy lives and not taking the time to think critically, it’s inevitable that some of us will become victims. And remember if you’re offered a deal that just seems too good to be true, then it’s likely a scam! Hang up or press delete!!

Pledging to follow healthier habits is consistently the most popular new year’s resolution. That January 1st promise looks different to everyone: snacking less often, going to the gym more often, drinking more water, drinking less soda, etc. This year, instead of a juice cleanse subscription, opt for a healthier habit that’s not an unappetizing shade of green: follow this digital detox, instead! In three easy steps, you can make great strides in improving your digital wellness.
There are various aspects of your digital habits that you should consider updating for a more private and safer online life. For starters, update your passwords. Do you reuse the same password for multiple online accounts? Doing so puts your personally identifiable information (PII) at great risk. For example, if a business with which you have an online shopping account is breached by a cybercriminal, your login and password combination could make it on the dark web, through no fault of your own. Then, through a brute force attack, a criminal could use that same password and username combo to walk into your banking or tax filing accounts.
Remembering unique, complicated passwords and passphrases for your dozens of online accounts would be impossible. Luckily, there’s software that remembers them for you! It’s called a password manager, which acts as a vault for all your login information. Just remember one master password, and you can be confident in the security of your accounts and never have to deal with the hassle of forgetting passwords.
Another aspect of updating you should adopt in 2023 is making an effort to always upgrade to the latest software updates on all your devices. The easiest way to do this is to turn on automatic updates. From there, you don’t need to take any further action! Apps and operating systems (like Apple, Android, and Windows) often release updates to patch security vulnerabilities. When you run outdated software, there’s a chance a cybercriminal could take advantage of that security gap.
Finally, make sure that you keep updated on the latest security headlines. Consider setting up news alerts to notify you when a breach occurs at a company that you frequent or have an account with. Speed is often key in making sure that your information remains safe, so it’s best practice to have your finger on the pulse on the security news of the day.
A new year digital detox can be a whole family affair. Connect with your family, anyone connected to your home network, and your elderly relatives to get everyone on the same page with security best practices. Here are some common online security snags people of all ages encounter:
Everyone has an oversharer on their newsfeed. Alert your family members of the dangers of posting too much about their personal life. When someone takes those “get to know you” quizzes and posts their answers, cybercriminals can use that post to take educated guesses at your passwords. Additionally, social engineers can tailor social media scams to specific people in order to increase the chances of tricking someone into sending money or sharing valuable personal or banking details.
While spam filters catch a lot of phishing emails, phishers are getting smarter by the day and are making their attempts more and more believable. Connect with your loved ones and make sure they know how to recognize phishing emails, texts, and social media direct messages. Telltale signs of a phishing message include:
If you’re ever unsure if a message is a phishing attempt, the best course of action is to just delete it. If the “sender” is a well-known institution, follow up with a phone call using the official customer service number listed on their website. The phisher may also claim to be someone you know personally. In that case, give the loved one in question a phone call. It’s a good excuse to reconnect and have a nice conversation!
In the quest for free streams of the latest new show or movie, people often encounter unsafe sites that hide malware, spyware or other types malicious links and programs. Some types of malware can jump from one device to others connected to the same home Wi-Fi network. That’s why it’s important to make sure everyone under your roof practices excellent digital security habits. One wrong click could sink an entire household. Consider signing up your family for a safe browsing extension that can notify you when you stray onto a risky site. So, instead of putting your device at risk during movie night, connect with your friends or loved ones over one copy of a safely and officially purchased version.
As with any new health regimen, immediately zooming from zero to a hundred will likely be overwhelming and result in failure. The same goes for adopting new digital safety habits. If you try to do too much at once, all the security measures you put in place will likely get in the way of your daily online activities. The more inconvenient it is, the more likely you may be to cut corners; thus, negating all the progress you’ve made.
Being cybersafe doesn’t mean you can’t still enjoy your connected devices to the fullest. It just means that you may need to act with more intention and slow down before volunteering personal details online or clicking on links.
To supplement your digital detox, consider signing up for McAfee+ Ultimate to make 2023 the year for a safer online you. McAfee+ Ultimate includes all the tools you need to live your best online life safely and privately, including a password manager, web protection, unlimited VPN and antivirus, and $1 million in identity theft coverage and restoration for peace of mind.
Cheers to a digitally smart 2023!

Happy Download Day! (Yes, there’s a day for that.) Today is an excellent day to share downloading best practices to keep all your devices safe from malicious content. It’s tempting to download “free” shows, movies, and video games, but the consequences of doing so can be quite expensive. All it takes is for one malicious download to compromise your identity or leak your banking information to cybercriminals.
Luckily, there are a few ways to keep your devices and personally identifiable information (PII) safe. Here’s how!
How many streaming services do you subscribe to? Two? Ten? No matter how many premium entertainment subscriptions you have, the hottest new show always seems to be on the channel you can’t access. This is a common scenario that often drives people to download episodes from websites that claim crystal-clear, safe downloads. In actuality, these sites could harbor malware, spyware, or other types of malware that lurk in the shadows until an unsuspecting person downloads them to their desktop, tablet, or cellphone.
Malware, which stands for malicious software, often hides behind legitimate-looking links or downloadable content. It’s only until it’s on your device that you realize there’s a criminal hiding behind it. For example, earlier in 2022, a ransomware program (a type of malware) disguised itself as a Microsoft system update. The criminal behind the scheme then threatened leaking or permanently deleting sensitive files if the person didn’t pay the ransom.
Once malware infects one device, some malware programs can infect an entire home network and spread to other connected devices.1 From there, the cybercriminal can steal the online shopping, banking, or personal details of a whole household and either sell their findings on the dark web or keep it for themselves.
Before you download anything to any of your devices, go through this checklist to help you determine the safety of most content:
Overall, while downloading entertainment for free is appealing to people on a budget, it’s better to avoid doing so altogether. The risk isn’t worth it. Consider scheduling a watch party with a friend or family member who has the subscription service you’re seeking.
In case you slip up and accidentally download malware, spyware, or ransomware, McAfee+ Ultimate can defend your devices, remove the software, and monitor the dark web to make sure your PII wasn’t compromised. McAfee antivirus is compatible with macOS, iOS, and Android devices and Chromebooks, so you can regularly scan all your devices for programs that shouldn’t be there. If the worst does happen and a cybercriminal gets a grip on your personal information, McAfee can back you up with $1 million in identity theft coverage and restoration and continuous identity monitoring.
Browse confidently and enjoy your devices to the fullest! Just remember these safe downloading tips and partner with McAfee for peace of mind.

Whether you’re spending time on the web or working in the office, you want peace of mind knowing that you are in a safe environment. While most of us know to take precautions when online — protecting ourselves from things like phishing attacks and other cyber threats — we should also attend to our physical security.
One concern is tailgating — a social engineering attack where someone gets physical access to a business to take confidential information or do other harm.
Here are some ways to protect yourself from tailgating attacks, such as an unauthorized person following you into a restricted area while on the job.
Tailgating is a type of social engineering attack where an unauthorized person gains physical access to an off-limits location — perhaps a password-protected area — where they might steal sensitive information, damage property, compromise user credentials or even install malware on computers.
“Piggybacking” is closely related to tailgating, but it involves consent from the duped employee. So, while a worker might be unaware that someone has tailgated them into a restricted area with piggybacking, the hacker might convince a worker to provide access because they are posing as, say, a delivery driver.
Companies, particularly at risk of being targeted by tailgating scams, include those:
Generally speaking, companies with robust security systems in place — including using biometrics, badges, or other identity and information security measures — are better protected from tailgating and piggybacking attacks.
But that’s not to say that some smooth-talking fraudster can’t talk someone into letting them in or finding some way around those protections.
Common types of tailgating attacks that you should be aware of on the job include:
Protecting yourself from tailgating attacks is partly a matter of learning about the issue, raising your level of awareness on the job, and depending on your employer, putting in place more effective security systems.
Some solutions include:
Many companies know how to train employees to recognize, avoid, and cope with online security issues but may forget to provide the same diligence to physical security. How to spot and deal with threats should be part of this training, plus cultivating an awareness of surroundings and people who might be out of place.
Management should offer a clearly stated security policy taught to everyone, which might insist that no one be allowed into a secure area without the proper pass or identification. As the security policy is updated, all employees should be aware of changes and additions.
These security measures should be part of an overall protection program, like McAfee+, which includes antivirus software, a firewall, identity monitoring, password management, web protection, and more.
If you have a large business spread over several floors, it can be hard for employees to know who works there and who doesn’t, leaving them susceptible to tailgating and piggybacking attacks. Requiring smart badges and cards to access restricted areas can help cut back on unauthorized intrusions and provide better access control.
Building fully staffed reception areas with dedicated security personnel could also be part of a larger security system.
Biometric scanners are an even more advanced way to provide proper authentication for a worker’s identity. They scan a unique physical or audible feature of a person and compare it to a database for approved personnel.
Examples of biometric security include:
One reason people are vulnerable to physical and cyberattacks is that they lack education on social engineering and the kinds of threats it poses.
Workers need to understand the full range of social engineering techniques and know-how to protect themselves, whether in their social media accounts or physical work environment.
For their part, companies can use simulated phishing emails and tailgating attacks to raise awareness and underline how to follow protocols in dealing with them.
If there are many ways to enter a business, it may make sense to put video surveillance on all entrances. Advanced video surveillance systems can use artificial intelligence (AI) and video analytics to scan the faces of people entering and compare them to a database of employee features.
Whether at work or at home, people want to be secure from attacks by cybercriminals who seek to take personal information.
To add a layer of security to all their connected devices — including computers, smartphones, and tablets — an increasing number of people are turning to the comprehensive coverage of McAfee+
Features range from advanced monitoring of possible threats to your identity, automatic implementation of virtual private networks (VPNs) to deal with unsafe networks, and personal data clean-up, removing your information from high-risk data broker sites.
McAfee protection allows you to work and play online with greater peace of mind.

What is antivirus? That’s a good question. What does it really protect? That’s an even better question.
Over the years, I’ve come to recognize that different people define antivirus differently. Some see it as way to keep hackers from crashing their computers. Others see it as a comprehensive set of protections. Neither definition is entirely on the money.
With this blog, I hope to give everyone a clear definition of what antivirus does well, along with what it doesn’t do at all. The fact is that antivirus is just one form of online protection. There are other forms of protection as well, and understanding antivirus’ role in your overall mix of online protection is an important part of staying safer online.
Antivirus software protects your devices against malware and viruses through a combination of prevention, detection, and removal.
For years, people have installed antivirus software on their computers. Today, it can also protect your smartphones and tablets as well. In fact, we recommend installing it on those devices as well because they’re connected, just like a computer—and any device that connects to the internet is a potential target for malware and viruses.
In short, if it’s connected, it must get protected.
One important distinction about antivirus is its name, a name that first came into use decades ago when viruses first appeared on the scene. (More on that in a bit.) However, antivirus protects you from more than viruses. It protects against malware too.
Malware is an umbrella term that covers all types of malicious software regardless of its design, intent, or how its delivered. Viruses are a subset of malicious software that infects devices and then replicates itself so that it can infect yet more devices.
So while we popularly refer to protection software as antivirus, it protects against far more than just viruses. It protects against malware overall.
Now here’s where some confusion may come in. Some antivirus apps are standalone. They offer malware protection and that’s it. Other antivirus apps are part of comprehensive online protection software, which can include several additional far-reaching features that can protect your privacy and your identity.
The reason why antivirus gets paired up with other apps for your privacy and identity is because antivirus alone doesn’t offer these kinds of protections. Yet when paired with things like a password manager, credit monitoring, identity theft coverage, and a VPN, to name a few, you can protect your devices—along with your privacy and identity. All the things you need to stay safer online.
In short, antivirus doesn’t cut it alone.
With that, let’s take a closer look at what malware and viruses really are—how they evolved, and what they look like today, along with how antivirus protects you against them.
Viruses have a long history. And depending on how you define what a virus is, the first one arguably took root in 1971—more than 50 years ago.
It was known as Creeper, and rather than being malicious in nature, it was designed to show how a self-replicating program could identify other connected devices on a network, transfer itself to them, and find yet more devices to repeat the process. Later, the same programmer who created a follow-on version of Creeper developed Reaper, a program that could remove the Creeper program. In a way, Reaper could be considered the first piece of antivirus software.
From there, it wasn’t until the 1980’s that malware started affecting the broader population, a time when computers became more commonplace in businesses and people’s homes.
At first, malware typically spread by infected floppy disks, much like the “Brain” virus in 1986. While recognized today as the first large-scale computer virus, its authors say they never intended it to work that way. Rather they say they created Brain as an anti-piracy measure to protect their proprietary software from theft. However, Brain got loose. It went beyond their software and affected computers worldwide. Although not malicious or destructive in nature, Brain most certainly put the industry, businesses, and consumers on notice.
Computer viruses became a thing.
Another piece of malware that got passed along via floppy disks was the “PC Cyborg” attack that targeted the medical research community in and around 1989. There the malware would lie in wait until the user rebooted their computer for the 90th time. And on that 90th boot, the user was presented with a digital ransom note like the one here:
Along with that note, PC Cyborg encrypted the computer’s files, which would only get unencrypted if the victim paid a fee—making PC Cyborg the first widely recognized form of ransomware.
Shortly thereafter, the internet started connecting computers, which opened millions of doors for hackers as people went online. Among the most noteworthy was 1999’s “Melissa” virus, which spread by way of infected email attachments and overloaded hundreds of corporate and governmental email servers worldwide.
It was quickly followed in 2000 by what’s considered the among the most damaging malware to date—ILOVEYOU, which also spread by way of an attachment, this one posing as a love letter. Specifically, it was a self-replicating worm that installed itself on the victim’s computer where it destroyed some information and stole other information, then spread to other computers. One estimate puts the global cost of ILOVEYOU at $10 billion and further speculated that it infected 10% of the world’s internet-connected computers at the time.
With the advent of the internet, malware quickly established itself as a sad fact of connected life. Today, McAfee registers an average of 1.1 million new malicious programs and potentially unwanted apps (PUA) each day, which contributes to the millions and millions of malicious programs already in existence.
Apart from the sheer volume of malware out there today, another thing that distinguishes today’s malware from early malware attacks—they’re created largely for profit.
We can think of it this way:
Today’s malware is far more than an annoyance or headache. It can lead to follow-on attacks that target your finances, your identity, your privacy, or a mix of all three.
So with a million or so new threats coming online each day, and millions more out there already, how does antivirus protect you from malware? It blocks, detects, and removes malware. And it does so in a couple of ways:
However, as mentioned earlier, antivirus provides only one aspect of online protection today. While it protects your devices and the data that’s on them, your privacy and identity can come under attack as well. So while antivirus alone can protect you from malware, it can’t prevent other forms of online crime like identity theft, phishing attacks designed to steal personal information, or attacks on your accounts, to name a few of the many other types of threats out there.
Yet comprehensive online protection can.
Comprehensive online protection software like ours offers antivirus, along with specific services and features that protect your privacy and identity online as well. It gives you dozens of other features like identity theft coverage & restoration, personal data cleanup, security freezes, and an online protection score that shows you just how safe you are, along with suggestions that can make you safer still.
So while protecting your devices with antivirus is a great start, it’s only one part of staying safer online. Including privacy and identity protection rounds out your protection overall.

It’s important to know that not all websites are safe to visit. In fact, some sites may contain malicious software (malware) that can harm your computer or steal your personal contact information or credit card numbers.
Phishing is another common type of web-based attack where scammers try to trick you into giving them your personal information, and you can be susceptible to this if you visit a suspicious site.
Identity theft is a serious problem, so it’s important to protect yourself when browsing the web. Online security threats can be a big issue for internet users, especially when visiting new websites or following site links.
So how can you tell if you’re visiting a safe website or an unsafe website? You can use a few different methods. This page discusses key things to look for in a website so you can stay safe online.
When you’re visiting a website, a few key indicators can help determine whether the site is safe. This section explores how to check the URL for two specific signs of a secure website.
“Https” in a website URL indicates that the website is safe to visit. The “s” stands for “secure,” and it means that the website uses SSL (Secure Sockets Layer) encryption to protect your information. A verified SSL certificate tells your browser that the website is secure. This is especially important when shopping online or entering personal information into a website.
When you see “https” in a URL, the site is using a protocol that encrypts information before it’s sent from your computer to the website’s server. This helps prevent anyone from intercepting and reading your sensitive information as it’s transmitted.
The padlock icon near your browser’s URL field is another indicator that a webpage is safe to visit. This icon usually appears in the address bar and means the site uses SSL encryption. Security tools and icon and warning appearances depend on the web browser.
Let’s explore the cybersecurity tools on the three major web browsers:
Overall, the ”https” and the locked padlock icon are good signs that your personal data will be safe when you enter it on a website. But you can ensure a website’s security is up to par in other ways. This section will explore five in-depth methods for checking website safety.
McAfee WebAdvisor is a free toolbar that helps keep you safe online. It works with your existing antivirus software to provide an extra layer of protection against online threats. WebAdvisor also blocks unsafe websites and lets you know if a site is known for phishing or other malicious activity. In addition, it can help you avoid online scams and prevent you from accidentally downloading malware. Overall, McAfee WebAdvisor is a useful tool that can help you stay safe while browsing the web.
When you’re browsing the web, it’s important to be able to trust the websites you’re visiting. One way to determine if a website is trustworthy is to look for trust seals. Trust seals are logos or badges that indicate a website is safe and secure. They usually appear on the homepage or checkout page of a website.
There are many types of trust seals, but some of the most common include the Better Business Bureau (BBB) seal, VeriSign secure seal, and the McAfee secure seal. These seals indicate that a third-party organization has verified the website as safe and secure.
While trust seals can help determine whether a website is trustworthy, it’s important to remember that they are not foolproof. Website owners can create a fake trust seal, so it’s always important to do your own research to ensure a website is safe before entering personal information.
Another way to determine if a website is safe to visit is to check for a privacy policy. A privacy policy is a document that outlines how a website collects and uses personal information. It should also state how the site protects your data from being accessed or shared by scammers, hackers, or other unauthorized individuals.
If a website doesn’t have a privacy policy, that’s a red flag that you shouldn’t enter any personal information on the site. Even if a website does have a privacy policy, it’s important to read it carefully so you understand how the site uses your personal data.
It’s important to do some preliminary research before visiting a new website, especially if you’re shopping online or entering personal data like your address, credit card, or phone number. One way to determine if a website is safe and trustworthy is to check third-party reviews. Several websites provide reviews of other websites, so you should be able to find several reviews for any given site.
Trustpilot is one example of a website that provides reviews of other websites.
Look for common themes when reading reviews. If most of the reviews mention that a website is safe and easy to use, it’s likely that the site is indeed safe to visit. However, if a lot of negative reviews mention problems with viruses or malware, you might want to avoid the site.
You can also analyze the website design when deciding whether a website is safe to visit. Look for spelling errors, grammatical mistakes, and anything that appears off. If a website looks like it was made in a hurry or doesn’t seem to be well-designed, that’s usually a red flag that the site might not be safe.
Be especially careful of websites that have a lot of pop-ups. These sites are often spammy or contain malware. Don’t download anything from a website unless you’re absolutely sure it’s safe. These malicious websites rarely show up on the top of search engine results, so consider using a search engine to find what you’re looking for rather than a link that redirects you to an unknown website.
If you’re unsure whether a website is safe to visit, download McAfee WebAdvisor for free. McAfee WebAdvisor is a program that helps protect you from online threats, such as malware and viruses. It also blocks pop-ups and other intrusive ads so you can browse the web without worry. Plus, it’s completely free to download and use.
Download McAfee WebAdvisor now and stay safe while browsing the web.

What color jersey will you be sporting this November and December? The World Cup is on its way to television screens around the world, and scores of fans are dreaming of cheering on their team at stadiums throughout Qatar. Meanwhile, cybercriminals are dreaming of stealing the personally identifiable information (PII) of fans seeking last-minute vacation and ticket deals.
Don’t let the threat of phishers and online scammers dampen your team spirit this World Cup tournament. Here are three common schemes cybercriminals will likely employ and a few tips to help you dribble around their clumsy offense and protect your identity, financial information, and digital privacy.
Phishers will be out in full force attempting to capitalize on World Cup fever. People wrapped up in the excitement may jump on offers that any other time of the year they would treat with skepticism. For example, in years past, fake contests and travel deals inundated email inboxes across the world. Some companies do indeed run legitimate giveaways, and cybercriminals slip in their phishing attempts among them.
If you receive an email or text saying that you’re the winner of a ticket giveaway, think back: Did you even enter a contest? If not, treat any “winner” notification with skepticism. It’s very rare for a company to automatically enter people into a drawing. Usually, companies want you to act – subscribe to a newsletter or engage with a social media post, for example – in exchange for your entry into their contest. Also, beware of emails that urge you to respond within a few hours to “claim your prize.” While it’s true that real contest winners must reply promptly, organized companies will likely give you at least a day if not longer to acknowledge receipt.
Traveling is rarely an inexpensive endeavor. Flights, hotels, rental cars, dining costs, and tourist attraction admission fees add up quickly. In the case of this year’s host country, Qatar, there’s an additional cost for American travelers: visas.
If you see package travel deals to the World Cup that seem too good to pass up … pass them up. Fake ads for ultra-cheap flights, hotels, and tickets may appear not only in your email inbox but also on your social media feed. Just because it’s an ad doesn’t mean it comes from a legitimate company. Legitimate travel companies will likely have professional-looking websites with clear graphics and clean website copy. Search for the name of the organization online and see what other people have to say about the company. If no search results appear or the website looks sloppy, proceed with caution or do not approach at all.
Regarding visas, be wary of anyone offering to help you apply for a visa. There are plenty of government-run websites that’ll walk you through the process, which isn’t difficult as long as you leave enough time for processing. Do not send your physical passport to anyone who is not a confirmed government official.
Even fans who’ve given up on watching World Cup matches in person aren’t out of the path of scams. Sites claiming to have crystal clear streams of every game could be malware spreaders in disguise. Malware and ransomware targeting home computers often lurk on sketchy sites. All it takes is a click on one bad link to let a cybercriminal or a virus into your device.
Your safest route to good-quality live game streams is through the official sites of your local broadcasting company or the official World Cup site. You may have to pay a fee, but in the grand scheme of things, that fee could be a lot less expensive than replacing or repairing an infected device.
Here’s an excellent rule to follow with any electronic correspondence: Never send anyone your passwords, routing and account number, passport information, or Social Security Number. A legitimate organization will never ask for your password, and it’s best to communicate any sensitive financial or identifiable information over the phone, not email or text as they can easily fall into the wrong hands. Also, do not wire large sums of money to someone you just met online.
Don’t let scams ruin your enjoyment of this year’s World Cup! With these tips, you should be able to avoid the most common schemes but to boost your confidence in your online presence, consider signing up for McAfee+. Think of McAfee+ as the ultimate goalkeeper who’ll block any cybercriminals looking to score on you. With identity monitoring, credit lock, unlimited VPN and antivirus, and more, you can surf safely and with peace of mind.

Smishing and vishing are scams where criminals attempt to get users to click a fraudulent link through a phone text message, email, or voicemail. These scams are becoming increasingly popular as cybercriminals try to take advantage of people who are more likely to fall for them, such as those who aren’t as familiar with technology or who may be experiencing a crisis.
Be aware that cybercrime and hacking can happen to anyone. Criminals are always looking for new ways to exploit people, and they know that others may not be cautious or recognize the warning signs of phishing scams when using the internet. That’s why it’s important to be aware of the different types of cybercrime and how to protect yourself.
This article discusses how to protect yourself from smishing attempts and scams where criminals try to get you to click on a fraudulent link or respond to their voicemail message to steal your personal data.
Most people are familiar with phishing scams, where scammers try to trick you into giving them your personal or financial information by pretending to be a legitimate company or organization. But have you ever heard of smishing or vishing?
Smishing is a type of phishing scam where attackers send SMS messages (or text messages) to trick victims into sharing personal information or installing malware on their devices. Vishing is almost identical to smishing, except cybercriminals use VoIP (Voice over IP) to place phone calls to trick victims instead of SMS (short message service) messages.
Smishing messages often appear to be from a legitimate source, such as a well-known company or government agency. It may even include urgent language or threats in an effort to get victims to act quickly. In some cases, the message may also include a link that directs victims to a fake website where they are prompted to enter personal information or download malware.
Here are some examples of smishing text messages hackers use to steal your personal details:
If you fall for a smishing scam, you could end up giving away your personal information or money. Cybercriminals use smishing messages to get personal and financial information, like your credit card number or access to your financial services.
For example, one type of smishing scam is when you get a text message that looks like it’s from your bank. The message might say there’s been suspicious activity on your account and that you need to click on a link to verify your identity. If you do click on the link, you’ll be taken to a fake website where you’ll be asked to enter your banking information. Once the scammers have your login information, they have access to clean out your account.
Smishing scams can be very difficult to spot, but there are some telltale signs to look for and steps to take to protect yourself.
One of the easiest ways to protect yourself from smishing scams is to be able to recognize the signs of a smishing text message. Here are some tips:
While you can’t avoid smishing attacks altogether, you can block spam text messages you receive on your mobile phone. iPhone and Android have cybersecurity tools like spam filters and phone number blocking to help protect you from phishing attacks and malicious links.

A new ransomware threat is currently sweeping its way across home computers. And what’s making it extra tricky is that it’s disguised as an operating system update.
Be on the lookout for this new ransomware scheme and protect yourself from ransomware with a few of these tips.
Magniber is a new type of ransomware that is disguised at almost every touchpoint until it seemingly pops out of nowhere demanding money. The attack begins when someone visits a fake Windows 10 update website owned by the Magniber cybercriminal group. Once someone clicks on a malicious link on that site, file-encrypting malware downloads onto the device.
Another stealth maneuver of Magniber is that the encryption malware downloads as a JavaScript file straight to the memory of the device, which can often slide under an antivirus’ radar. This malware allows the criminal to view, delete, and encrypt files and gain administrator access of the device. Usually, before the person even knows their device is in danger, Magniber reveals itself and demands a ransom payment in exchange for releasing the documents and giving back control of the computer. If the device owner refuses to pay, the criminal threatens to delete the files forever.1
For the last several years, large companies fell left and right to breaches. Hacker groups infiltrated complex cybersecurity defenses, got ahold of sensitive company or customer information, and threatened to release their findings on the dark web if not paid a hefty ransom. The reasons cybercriminals targeted corporate databases versus personal devices wasn’t just because they could demand multiple millions, but because companies were better equipped to make ransom transactions anonymously. Often, cryptocurrency transactions are untraceable, which allows criminals to remain at large.
Now that more everyday people are proficient in cryptocurrency, ransomware may shift to targeting personal devices. Though the ransom payments won’t be as lucrative, there also won’t be corporate cybersecurity experts hot on the cybercriminal’s tail.
To avoid ransomware schemes similar to Magniber, adopt these three habits to better protect your device and digital privacy:
If a cybercriminal gets in touch with you and demands a ransom, immediately contact your local FBI field office and file a report with the FBI’s Internet Criminal Complaint Center. From there, the authorities will advise you on how to proceed.
Something you can start with now to defend against ransomware is to invest in McAfee+ Ultimate. It provides the most thorough device, privacy, and identity protection, including $25,000 in ransomware coverage.

One of the oldest tricks in the cybercrime playbook is phishing. It first hit the digital scene in 1995, at a time when millions flocked to America Online (AOL) every day. And if we know one thing about cybercriminals, it’s that they tend to follow the masses. In earlier iterations, phishing attempts were easy to spot due to link misspellings, odd link redirects, and other giveaways. However, today’s phishing tricks have become personalized, advanced, and shrouded in new disguises. So, let’s take a look at some of the different types, real-world examples and how you can recognize a phishing lure.
Every day, users get sent thousands of emails. Some are important, but most are just plain junk. These emails often get filtered to a spam folder, where phishing emails are often trapped. But sometimes they slip through the digital cracks, into a main inbox. These messages typically have urgent requests that require the user to input sensitive information or fill out a form through an external link. These phishing emails can take on many personas, such as banking institutions, popular services, and universities. As such, always remember to stay vigilant and double-check the source before giving away any information.
A sort of sibling to email phishing, link manipulation is when a cybercriminal sends users a link to malicious website under the ruse of an urgent request or deadline. After clicking on the deceptive link, the user is brought to the cybercriminal’s fake website rather than a real or verified link and asked to input or verify personal details. This exact scenario happened last year when several universities and businesses fell for a campaign disguised as a package delivery issue from FedEx. This scheme is a reminder that anyone can fall for a cybercriminals trap, which is why users always have to careful when clicking, as well as ensure the validity of the claim and source of the link. To check the validity, it’s always a good idea to contact the source directly to see if the notice or request is legitimate.
Corporate executives have always been high-level targets for cybercriminals. That’s why C-suite members have a special name for when cybercriminals try to phish them – whaling. What sounds like a silly name is anything but. In this sophisticated, as well as personalized attack, a cybercriminal attempts to manipulate the target to obtain money, trade secrets, or employee information. In recent years, organizations have become smarter and in turn, whaling has slowed down. Before the slowdown, however, many companies were hit with data breaches due to cybercriminals impersonating C-suite members and asking lower-level employees for company information. To avoid this pesky phishing attempt, train C-suite members to be able to identify phishing, as well as encourage unique, strong passwords on all devices and accounts.
Just as email spam and link manipulation are phishing siblings, so too are whaling and spear-phishing. While whaling attacks target the C-suite of a specific organization, spear-phishing rather targets lower-level employees of a specific organization. Just as selective and sophisticated as whaling, spear-phishing targets members of a specific organization to gain access to critical information, like staff credentials, intellectual property, customer data, and more. Spear-phishing attacks tend to be more lucrative than a run-of-the-mill phishing attack, which is why cybercriminals will often spend more time crafting and obtaining personal information from these specific targets. To avoid falling for this phishing scheme, employees must have proper security training so they know how to spot a phishing lure when they see one.
With so many things to click on a website, it’s easy to see why cybercriminals would take advantage of that fact. Content spoofing is based on exactly that notion – a cybercriminal alters a section of content on a page of a reliable website to redirect an unsuspecting user to an illegitimate website where they are then asked to enter personal details. The best way to steer clear of this phishing scheme is to check that the URL matches the primary domain name.
When users search for something online, they expect reliable resources. But sometimes, phishing sites can sneak their way into legitimate results. This tactic is called search engine phishing and involves search engines being manipulated into showing malicious results. Users are attracted to these sites by discount offers for products or services. However, when the user goes to buy said product or service, their personal details are collected by the deceptive site. To stay secure, watch out for potentially sketchy ads in particular and when in doubt always navigate to the official site first.
With new technologies come new avenues for cybercriminals to try and obtain personal data. Vishing, or voice phishing, is one of those new avenues. In a vishing attempt, cybercriminals contact users by phone and ask the user to dial a number to receive identifiable bank account or personal information through the phone by using a fake caller ID. For example, just last year, a security researcher received a call from their financial institution saying that their card had been compromised. Instead of offering a replacement card, the bank suggested simply blocking any future geographic-specific transactions. Sensing something was up, the researcher hung up and dialed his bank – they had no record of the call or the fraudulent card transactions. This scenario, as sophisticated as it sounds, reminds users to always double-check directly with businesses before sharing any personal information.
As you can see, phishing comes in all shapes and sizes. This blog only scratches the surface of all the ways cybercriminals lure unsuspecting users into phishing traps. The best way to stay protected is to invest in comprehensive security and stay updated on new phishing scams.

Your phone buzzes. You hope it’s a reply from last night’s date, but instead you get an entirely different swooping feeling: It’s an alarming SMS text alerting you about suspicious activity on your bank account and that immediate action is necessary.
Take a deep breath and make sure to read the message carefully. Luckily, your assets could be completely safe. It could just be a smisher.
Smishing, or phishing over SMS, is a tactic where cybercriminals impersonate reputable organizations or people and trick people into handing over their PII or financial details. Sometimes they can seem very credible with the information they have, and you may have even been expecting a correspondence of a similar nature.
So how can you tell when an SMS text is real and requires your attention? And how should you deal with a smisher to keep your identity safe?
Like email phishing and social media phishing,
SMS text phishing often tries to use a strong emotion – like fear, anger, guilt, or excitement – to get you to respond immediately and without thinking through the request completely.
In the case of one coordinated smishing attack, cybercriminals not only impersonated financial institutions but collected PII on their targets ahead of time. The criminals then used these personal details – like old addresses and Social Security Numbers – to convince people that they were legitimate bank employees.1 But since when does a bank try to prove itself to the customer? Usually, it’s the other way around, where they’ll ask you to confirm your identity. Be wary of anyone who texts or calls you and has your PII. If you’re ever suspicious of a caller or texter claiming they’re a financial official, contact your bank through verified channels (chat, email, or phone) you find on the bank’s website to make sure.
Smishers often keep up with current events and attempt to impersonate well-known companies that have a reason to reach out to their customers. This adds false legitimacy to their message. For example, in the summer of 2022, Rogers Communications, a Canadian telecommunications provider, experienced an extended loss of service and told customers they could expect a reimbursement. Smishers jumped on the opportunity and sent a barrage of fake texts requesting banking details in order to carry out the reimbursement.2 However, Rogers credited customers directly to their Rogers accounts.
If you receive a suspicious text, go through these three steps to determine if you should follow up with the organization in question or simply delete and report the text.
Do you have text alerts enabled for your bank and utility accounts? If not, disregard any text claiming to be from those organizations. Companies will only contact you through the channels you have approved. Also, in the case of the Rogers smishing scheme, be aware of how a company plans to follow up with customers regarding reimbursements. You can find information like this on their official website and verified social channels.
If the tone of the text urges you to act quickly or proposes a dire consequence of ignoring the message, be on alert. While suspicious activity on your credit card is serious, your bank will likely reimburse you for charges you didn’t make, so you have time to check your bank account and see recent activities. Official correspondence from financial institutions will always be professional, typo-free, and will try to put you at ease, not make you panic.
Whenever you get a text from someone you don’t know, it’s a good practice to do an internet search for the number to see with whom it’s associated. If it’s a legitimate number, it should appear on the first page of the search results and direct to an official bank webpage.
Once you’ve identified a fake SMS alert, do not engage with it. Never click on any links in the message, as they can redirect you to risky sites or download malware to your device. If you have McAfee Safe Browsing on your mobile, it can be your backup if you accidentally open a malicious link.
Also, don’t reply to the text. A reply lets the criminal on the other end know that they reached a valid phone number, which may cause them to redouble their efforts. Finally, block the number and report it as spam.
A great absolute rule to always follow is to never give out your Social Security Number, banking information, usernames, or passwords over text.
To give you peace of mind in cases where you think a malicious actor has access to your PII, you can count on McAfee+. McAfee+ offers a comprehensive suite of identity and privacy protection services to help you feel more confident in your digital life.

It’s hard to imagine a world without cellphones. Whether it be a smartphone or a flip phone, these devices have truly shaped the late 20th century and will continue to do so for the foreseeable future. But while users have become accustomed to having almost everything they could ever want at fingertips length, cybercriminals were busy setting up shop. To trick unsuspecting users, cybercriminals have set up crafty mobile threats – some that users may not even be fully aware of. These sneaky cyberthreats include SMSishing, fake networks, malicious apps, and grayware, which have all grown in sophistication over time. This means users need to be equipped with the know-how to navigate the choppy waters that come with these smartphone-related cyberthreats. Let’s get started.
If you use email, then you are probably familiar with what phishing is. And while phishing is commonly executed through email and malicious links, there is a form of phishing that specifically targets mobile devices called SMSishing. This growing threat allows cybercriminals to utilize messaging apps to send unsuspecting users a SMSishing message. These messages serve one purpose – to obtain personal information, such as logins and financial information. With that information, cybercriminals could impersonate the user to access banking records or steal their identity.
While this threat was once a rarity, it’s rise in popularity is two-fold. The first aspect being that users have been educated to distrust email messages and the second being the rise in mobile phone usage throughout the world. Although this threat shows no sign of slowing down, there are ways to avoid a cybercriminal’s SMSishing hooks. Get started with these tips:
Public and free Wi-Fi is practically everywhere nowadays, with some destinations even having city-wide Wi-Fi set up. But that Wi-Fi users are connecting their mobile device to may not be the most secure, given cybercriminals can exploit weaknesses in these networks to intercept messages, login credentials, or other personal information. Beyond exploiting weaknesses, some cybercriminals take it a step further and create fake networks with generic names that trick unsuspecting users into connecting their devices. These networks are called “evil-twin” networks. For help in spotting these imposters, there are few tricks the savvy user can deploy to prevent an evil twin network from wreaking havoc on their mobile device:
Fake apps have become a rampant problem for Android and iPhone users alike. This is mainly in part due to malicious apps hiding in plain sight on legitimate sources, such as the Google Play Store and Apple’s App Store. After users download a faulty app, cybercriminals deploy malware that operates in the background of mobile devices which makes it difficult for users to realize anything is wrong. And while users think they’ve just downloaded another run-of-the-mill app, the malware is hard at work obtaining personal data.
In order to keep sensitive information out of the hands of cybercriminals, here are a few things users can look for when they need to determine whether an app is fact or fiction:
With so many types of malware out in the world, it’s hard to keep track of them all. But there is one in particular that mobile device users need to be keenly aware of called grayware. As a coverall term for software or code that sits between normal and malicious, grayware comes in many forms, such as adware, spyware or madware. While adware and spyware can sometimes operate simultaneously on infected computers, madware — or adware on mobile devices — infiltrates smartphones by hiding within rogue apps. Once a mobile device is infected with madware from a malicious app, ads can infiltrate almost every aspect on a user’s phone. Madware isn’t just annoying; it also is a security and privacy risk, as some threats will try to obtain users’ data. To avoid the annoyance, as well as the cybersecurity risks of grayware, users can prepare their devices with these cautionary steps:

Internet security is a broad term that refers to a wide range of tactics that aim to protect activities conducted over the internet. Implementing internet security measures helps protect users from different online threats like types of malware, phishing attacks, scams, and even unauthorized access by hackers.
In this article, we highlight the importance of internet security in safeguarding your computer network and outline what you can do to have a comprehensive computer security system in place.
As the internet expands and becomes an even bigger part of our lives, cyberthreats continue to grow both in scope and sophistication. According to Forbes, data breaches and cyberattacks saw an increase of 15.1% in 2021 compared to the previous year. These security threats come in different forms and vary in terms of complexity and detectability.
Some common online threats people face today include:
While these internet security threats may seem overwhelming at first glance, safeguarding your computer or mobile devices from them is relatively easy. Below is a detailed look at some security solutions available to you.
As we stated above, setting up an internet security system is a relatively straightforward process. Here are some basic network security measures you can implement right away.
The first step in making sure you have internet security is installing antivirus software. These programs are designed to prevent, search for, detect, and get rid of viruses and other types of malicious software.
Antivirus software can run automatic scans to make sure no network or data breach has occurred and scan specific files or directories for any malicious activity or patterns.
There are plenty of options to choose from when it comes to antivirus software, however, few programs offer the comprehensive level of protection the antivirus software included in McAfee® Total Protection provides to its users.
McAfee’s antivirus software comes with a wide selection of features, including malware detection, quarantine, and removal, different options for scanning files and applications, and an advanced firewall for home network security.
While this may sound obvious, it’s important to create strong and unique passwords for all your online accounts and devices. A significant percentage of data breaches occur as a result of simple password guessing.
Some tips to follow when creating a password include:
It can also be a good idea to use a password manager, as this will help reduce the risk of your passwords getting leaked or lost. McAfee’s password manager, is particularly convenient thanks to its advanced encryption and multi-factor authentication.
A firewall is a network security system built into your operating system. It monitors incoming and outgoing network traffic to prevent unauthorized access to your network. For it to be able to identify and block these threats, you’ll want to make sure your firewall is enabled on your device. If you’re unsure if your device comes with a firewall, you can benefit from one included in McAfee Total Protection.
Multi-factor authentication (MFA) is an authentication method that requires at least two pieces of evidence before granting access to an app or website. Using this method as much as possible can add another layer of security to your applications and reduce the likelihood of a data breach.
Your choice of browser is an important part of implementing internet security measures. In fact, web browsers vary widely in terms of the security features that they offer, with some offering just the basics and others providing a more complete range of features. Ideally, you should opt for a web browser that offers the following security features:
As children grow older, their internet use becomes more extensive. This can also increase their exposure to various security threats. To keep them safe online, educate them about the risks associated with web browsing and introduce them to some of the best practices for avoiding online threats like not sharing passwords.
Explain which information should be shared and which information should be kept private and instruct them to never click on links from unknown sources.
You should also take a more active approach to protect your children by setting parental controls on certain websites. For instance, you can use YouTube’s parental controls to filter any inappropriate content and keep a child-friendly interface.
The following tips can help you stay on the safe side in regard to internet security.
While malware attacks are common, their prevalence shouldn’t deter you from browsing the internet as usual. Adhering to the internet security best practices outlined in this article can help keep you safe from the majority of security threats that you might encounter online.
For added security, consider using an all-in-one antivirus solution like McAfee+. This is one of the most effective ways to safeguard your devices from online threats.

A virtual private network (VPN) is a tool that enables users to protect their privacy while using an internet connection. VPNs create an encrypted tunnel — a private link between your device and the VPN server.
Essentially, this private link or tunnel keeps external influences out and allows your data to travel in an encrypted manner, enhancing security. The network’s privacy also makes sure your Internet Protocol (IP) address and browsing history is hidden online.
[Text Wrapping Break]VPNs use several VPN protocols like OpenVPN, IPSec/IKEv2, PPTP, SSTP, and WireGuard to protect you. In particular, McAfee® Safe Connect VPN supports the OpenVPN protocol, which is an open-source and highly secure protocol running on TCP or UDP internet protocol and used by many VPN providers globally. [Text Wrapping Break][Text Wrapping Break]Read on to know more about how VPNs work and learn to install one.
The best way to stay secure online is to minimize your digital footprint. A good VPN service allows you to do exactly this, acting as an additional layer of protection for your online activities.
The primary function of a VPN is encryption. Most websites and online browsers already have some form of encryption. For example, when you purchase something on Amazon, you have to enter your credit card details and address. Encryption creates a private tunnel for data transmission between your device and Amazon to make sure no one else can watch what you’re doing.
A VPN app does the same thing with an added level of security. The data that you pass to a VPN server is anonymized before it goes to the internet. In short, your device establishes an encrypted connection with the VPN server instead of connecting directly through the internet. So, the encryption protects your data and digital footprint from anyone outside the “private tunnel” between you and the secure VPN server.
Additionally, VPNs allow you to change or hide your IP address. An IP address is a number linked to a particular computer and network. Changing your IP address can trick the servers into thinking you’re connecting from a different geographical location. This can help improve security and provide additional benefits discussed below.
You can also use a VPN to hide your IP address. This may be helpful if you’re trying to access content from other countries (for example, Netflix may have different content in different countries) or trying to keep your internet search history away from the prying eyes of a third-party like your internet service provider or a government.
Using a VPN can help improve your online security. Nearly every internet activity — website and social media browsing, paying bills, online shopping, data sharing, and more — can be tracked by others. [Text Wrapping Break][Text Wrapping Break]Read on to learn about who typically uses a VPN and understand whether you should consider installing one.
Given the extra security that VPN connections provide, you can gain something from using a VPN client. So, if you’re an individual concerned about your online privacy or just want to browse online anonymously — consider using a VPN. A VPN enables you to use the internet without third parties seeing your identity or identifying you via your search history since they don’t know what you were searching about or using the internet for.
Big tech has had a long history of tracking private data for their gains. These companies regularly bundle data into coherent profiles and sell it to third parties. Additionally, they use private data to demonstrate targeted advertisements or manipulative content that makes you more likely to purchase their products. [Text Wrapping Break][Text Wrapping Break]So, it’s worthwhile to use a VPN if you regularly shop online or bank online. A VPN gives you that additional protection that can help prevent hackers or malicious third parties from accessing your information.[Text Wrapping Break][Text Wrapping Break]VPNs are excellent mechanisms for you to protect your privacy online. And you should consider your personal context and conduct thorough research to find the best VPN for your needs.
VPNs are particularly helpful if you travel a lot, either for business or for leisure. While traveling, it’s inevitable that you connect to random or unknown Wifi networks and it may be the case that these networks are spying on you. However, if you’re using a VPN to browse the web, these WiFi networks can’t track you or your search history. This ensures you maintain anonymity and are safe while using the internet.
Yes, an additional layer of protection to your online activities is always good practice. A VPN allows individuals using a personal computer to stay vigilant, protect their data, and maintain anonymity while allowing them to still enjoy their online experience.
VPNs provide more benefits than just serving as an additional layer for cybercriminals to pass through.
Depending on the VPN you’re using, it can be a straightforward process to connect a VPN to your Mac, Windows, iPhone, or Android mobile device. McAfee’s VPN works with multiple platforms and operating systems, including Microsoft Windows, macOS, Android, and iOS.
Use this guide to quickly set up a VPN with your device in a few simple steps.
With McAfee +, you can minimize your digital footprint through a secure connection channel without compromising your browsing experience. Connect to public networks, make financial transactions online, and keep your personal data safe with McAfee.
With our bank-grade AES-256 bit encryption technology and automatic protection, McAfee VPN protection can help safeguard all your online activities — allowing you to enjoy the internet the way it was meant to be enjoyed.

How do hackers hack phones? Several ways. Just as there are several ways you can prevent it from happening to you.
The thing is that our phones are like little treasure chests. They’re loaded with plenty of personal data, and we use them to shop, bank, and take care of other personal and financial matters—all of which are of high value to identity thieves.
However, you can protect yourself and your phone by knowing what to look out for and by taking a few simple steps. Let’s break it down by first taking a look at some of the more common attacks.
Whether hackers sneak it onto your phone by physically accessing your phone or by tricking you into installing it via a phony app, a sketchy website, or a phishing attack, hacking software can create problems for you in a couple of ways:
Some possible signs of hacking software on your phone include:
In all, hacking software can eat up system resources, create conflicts with other apps, and use your data or internet connection to pass along your personal information into the hands of hackers—all of which can lead to some of the symptoms listed above.
These are a classic form of attack. In fact, hackers have leveled them at our computers for years now too. Phishing is where hackers impersonate a company or trusted individual to get access to your accounts or personal info or both. And these attacks take many forms, like emails, texts, instant messages, and so forth, some of which can look really legitimate. Common to them are links to bogus sites that attempt to trick you into handing over that info or that install malware to wreak havoc on your device or likewise steal information. Learning how to spot a phishing attack is one way to keep yourself from falling victim to one.
Professional hackers can use dedicated technologies that search for vulnerable mobile devices with an open Bluetooth connection. Hackers can pull off these attacks when they are range of your phone, up to 30 feet away, usually in a populated area. When hackers make a Bluetooth connection to your phone, they can possibly access your data and info, yet that data and info must be downloaded while the phone is within range. As you probably gathered, this is a more sophisticated attack given the effort and technology involved.
In August of 2019, the CEO of Twitter had his SIM card hacked by SIM card swapping scam. SIM card swapping occurs when a hacker contacts your phone provider, pretends to be you, and then asks for a replacement SIM card. Once the provider sends the new SIM to the hacker, the old SIM card will be deactivated, and your phone number will be effectively stolen. This means the hacker has taken control of your phone calls, messages, and so forth. This method of hacking requires the seemingly not-so-easy task of impersonating someone else, yet clearly, it happened to the CEO of a major tech company. Protecting your personal info and identity online can help prevent hackers from impersonating you to pull off this and other crimes.
While there are several ways a hacker can get into your phone and steal personal and critical information, here are a few tips to keep that from happening:

Our all-new ransomware coverage is now available, ready to help just in case—all backed by expert advice to help you find the quickest and best possible path to recovery.
Ransomware coverage from McAfee can reimburse you up to $25,000 for losses resulting from a ransomware threat, including financial losses and ransom fees. You’ll find this ransomware coverage included with our McAfee+ Ultimate plan.
As well as eligibility for ransomware reimbursement, our team of experts can help you:
However, it’s important to realize that ransomware is unlike any other attack. When ransomware locks someone out of their device or encrypts their data and files so they can’t use them, a demand is usually made for money. Sometimes, paying the ransom results in the device being made accessible again or the files being decrypted. Yet like any ransom case, this result is not always guaranteed. There are plenty of cases where people pay the ransom but never get their data or access to their devices back.
Again, our coverage includes guidance from our expert advisers to help walk you through your options should the worst happen to you. You won’t be in it alone—particularly as you look to recover from what can be a complicated attack.
As the name implies, ransomware is a type of malware that holds your device or information for ransom. It may lock your computer or smartphone entirely or it may you out of your files by encrypting them so that you can’t access them. Whether it’s a hacker or a cybercrime organization behind the attack, the bad actor involved holds the key to unlock those files—and promises to do so. For a price. And as mentioned above, sometimes that doesn’t happen, even if you pay.
Ransomware can infect your devices several different ways:
Ransomware has seen quite the evolution over the years. Its origins date back to the late 1980s, where malware-loaded floppy disks were sent to users who installed them under false pretenses. There the malware would lie in wait until the user rebooted their computer for the 90th time and presented with a digital ransom note.
From there, ransomware attacks on individuals became more sophisticated, and more lucrative, with the advent of the internet and the millions of everyday users who flocked to it. Using phishing emails, malware downloads from phony sites, and compromised software and networks, hackers rapidly expanded their ransomware reach.
However, yet more lucrative for hackers and organized cybercriminals were public and private organizations. Shifting their attacks to so-called “big game” targets, hackers and organized cybercriminals have used ransomware to extort money from hospitals, city governments, financial institutions, and key energy infrastructure companies, to name just a few. Seeing further opportunity, ransomware attackers then began targeting smaller and mid-sized businesses as well. While the ransom demands account for lower amounts, these organizations often lack dedicated cybersecurity teams and the protections that come along with them, making these organizations easier to victimize.
Meanwhile, the body of malicious code and attack packages used to launch ransomware attacks has only grown. As a result, small-time hackers and hacking groups can find the tools they need to conduct an attack for sale or for lease as a service (Ransomware as a Service, or RaaS). In effect, these bad actors can simply access a dark web marketplace and figuratively pull a ready-to-deploy attack off the shelf.
As a result, ransomware remains a concern for individuals, even as businesses and governmental bodies of all sizes deal with its threat.
What makes ransomware so damaging is just how much effort it can take to undo. Setting aside the sophisticated attacks on businesses and governments for a moment, even those “off-the-shelf” attacks that some hackers will launch against individuals go beyond the average user’s ability to undo. For example, there are some known attacks with known methods of decrypting the data, however, that requires knowing specifically which attack was used. Attempting to undo the encryption with the wrong solution can potentially encrypt that data even more.
So without question, the best defense against ransomware is prevention. Comprehensive online protection software gives you the tools you need to help avoid becoming a ransomware victim. A few include:
Moreover, you can protect yourself further by backing up your files and data. A cloud storage solution,121cwdv 1765ujb n4yh that’s secured with a strong and unique password, offers one path. Likewise, you can back up your files on an external disk or drive, making sure to keep it disconnected from your network and stored in a safe place.
Also as mentioned in the bullets above, keep your operating system and apps current with the latest updates. Beyond making improvements in your operating system and apps, updates often also address security issues that hackers often use to compromise devices and apps.
Lastly, stay alert. Keep an eye out for sketchy links, attachments, websites, and messages. Bad actors will pull all kinds of phishing tricks to lure you their way, places where they try to compromise you, your devices, and data.
Taken together, the combination of online protection software and a few preventative steps can greatly reduce the chance that you’ll fall victim to ransomware. From there, you also have the assurance of our ransomware coverage, ready to get on the path to recovery, just in case.

Have you ever said something you wish you could take back? Maybe it was a comment muttered in the heat of the moment that hurt someone’s feelings. Or maybe you just had a night out full of silly antics that you wouldn’t want your boss or grandma to see.
These are completely normal occurrences that happen all the time. We’re human! We make mistakes and letting loose every now and again is good for us. When these scenarios happen in person, we’re able to apologize or explain ourselves; however, the social media age complicates things. High-def cameras and video recorders are in everyone’s pocket, meaning that in-person slip-ups or lapses in judgement can come back to haunt you in a cyberscheme known as doxing.
Doxing can be harmful to one’s reputation and can cost someone their job, their friends, or their privacy. Here are five things you should know about doxing, plus some tips on how to prevent it from happening to you.
The term doxing originated from the phrase “dropping documents/docs.” It refers to a situation where an enemy or a rival seeks to tarnish the reputation of someone else by releasing documents (aka dropping docs) about them. These documents often contain personally identifiable information (PII) – like full names, birthdates, addresses, employment details, financial information, phone numbers, email addresses – and private correspondences or embarrassing videos or photos. The doxer – or the person dropping the documents – will publish these private details online, whether that’s on a forum, on social media, or a blog.
Doxing is considered cyberbullying because it is a form of online harassment. The doxer often does so with the intent of drumming up widespread hate about the victim and having the release of these private details negatively affect the victim’s life, such as getting them fired from their job or breaking up a relationship.
Doxing happens most frequently to public figures, such as celebrities, politicians, streamers, and journalists. It is also a prevalent practice in the hacking community, where hackers reveal the identities of the real people behind forum usernames. However, anyone is susceptible to having their PII or sensitive photos or videos widely released on the internet for the sake of reputation sabotage. All it takes is for one scorned partner, a disgruntled coworker, or a disagreement to set a doxer on a warpath.
When the saboteur doesn’t have to dig into your past via the dark web or through hacking a personal device, doxing isn’t illegal. It’s malicious and can be emotionally damaging, but there is no law stopping a doxer from publishing the private details of someone else. Doxing crosses the line into a crime when it is accompanied by threats.
So, if a doxer didn’t hack a personal device or buy the PII off the dark web, where did they find these details? Oftentimes, people incriminate themselves with their social media footprint. What seems like ancient history in your social media timeline is again front and center after just a few minutes of scrolling.
Check out these tips that can lessen the chances of doxing happening to you:
In addition to the above tips, McAfee can help you fill in the gaps in your defense. McAfee Total Protection is an all-in-one privacy and identity protection service that includes all the tools you need to secure your PII and help you recover if identity theft occurs after a doxing incident. Personal Data Cleanup scans 40 risky data broker sites for your information. If you appear on any of those sites, McAfee will help you remove it to keep your PII out of a doxer’s hands.

Spam and bot accounts on social media are everywhere. You’ve likely encountered messages like these that attempt to get you to click on links or to stir your emotions in a frenzy. While bot accounts are usually more of an annoyance than anything, when they’re allowed to run rampant, they can quickly become dangerous to your personally identifiable information (PII) and create an emotionally charged mob mentality.
Here’s what you should know about bot accounts, including how to steer clear of menacing ones, plus a reminder to watch what you share on (and with) social media sites.
Bot accounts are software-automated accounts that try to blend in and act like a real user. They post updates and follow other users, though there isn’t a real person behind the account. A spam account is a type of bot account that attempts to gain financially from its automated posts. Everyday people should be wary of social media bot accounts because they can be used to disseminate false information or phishing scams.
One whistleblower of a social media giant recently divulged that the platform isn’t prioritizing deactivating bot accounts.1 This apathy sparks concerns about the company’s commitment to the security of its users. In the whistleblower’s same report, he stated that the social media site isn’t taking the necessary steps to protect itself from potential inside threats and it had fallen victim to at least 20 breaches in 2020 without reporting the incidents to the proper authorities.
Some bot accounts aren’t malicious (merely an annoying tactic by companies to spread the word about their business), but it’s best to give all of them a wide berth and never click on any links in their posts. Those links could direct to unsecured outside sites laden with malware or drop you in the middle of a phishing scheme.
You can often spot a malicious bot account by the tone of its messages. They’ll often try to inspire intense emotions, such as excitement, sadness, or rage, and attempt to get users to act or share the post. Do not engage with them, not even to argue their points. When you engage or share these posts with your network, it spreads false information and could dangerously manipulate public opinion.2
Here are a few ways you can take your cybersecurity into your own hands when you can’t be sure that social media sites are looking out for the safety of users’ information:
You can’t trust every company to look out for the safety of your personal information, but one organization you can trust is McAfee. McAfee Total Protection is a comprehensive identity and privacy protection solution for your digital life. Great social media habits go a long way toward keeping you safe online, and you can rest assured knowing that McAfee can fill in the gaps. McAfee Total Protection offers antivirus, identity monitoring, and security freeze in the case your information is leaked in a breach or a bot account gets ahold of key details.
Keep on sharing your life’s milestones with your closest friends and family online. The next time you update your status, flag any suspicious accounts you come across, so everyone can enjoy social media confidently!

We’ve all heard about the Metaverse. And there’s no doubt it has certainly captured the attention of the world’s biggest companies: Facebook has changed its name to Meta, Hyundai has partnered up with Roblox to offer virtual test drives, Nike has bought a virtual shoe company and Coca-Cola is selling NFT’s there too. (Non-Fungible Tokens – think digital assets).
But if you are confused about exactly what this all means and most importantly, what the metaverse actually is, then you are not alone. I’m putting together a 2-part series for parents that will help us get a handle on exactly what this new digital frontier promises and what we need to know to keep our kids safe. It will also ensure we don’t feel like dinosaurs! So, let’s get started.
I think the best way of describing the Metaverse is that it’s a network of online 3D virtual worlds that mimic the real world. Once users have chosen their digital avatar, they can meet people, play games, do business, design fashion items, buy real estate, attend events, earn money, rear a pet – in fact, almost anything they can do in the ‘real’ world! And of course, all transactions are via cryptocurrencies.
If you are an avid Science Fiction reader, then you may have already come across the term in the 1992 novel ‘Snow Crash’ by Neal Stephenson. In the book, Stephenson envisions a virtual reality-based evolution of the internet in which his characters use digital avatars of themselves to explore the online world. Sounds eerily familiar, doesn’t it?
Still confused? Check out either the book or Steven Spielberg’s movie adaption of Ernest Cline’s Ready Player One. Set in 2045, the book tells the story of people living in a war-ravaged world on the brink of collapse who turn to OASIS, a massively multiplayer online simulation game that has its own virtual world and currency. In the OASIS, they engage with each other, shop, play games and be transported to different locations.
The best and most immersive way to access the metaverse is using a Virtual Reality (VR) headset and your internet connection, of course. VR headsets completely take over users’ vision and replace the outside world with a virtual one. Now, this maybe a game or a movie but VR headsets have their own set of apps which once downloaded, allows users to meditate, learn piano, work out at the gym or even attend a live concert in the metaverse!
Now access to the Metaverse is not just limited to those who own expensive headsets. Anyone with a computer or a smartphone (that is internet connected) can also have a metaverse experience. Of course, it won’t be as intense or immersive as the VR headset experience but it’s still a commonly used route to access the metaverse. Some of these ‘worlds’ suggest users can access their world using smartphones however experienced users don’t think this is a good idea as phones don’t have the necessary computational power to explore the metaverse properly.
As some of the most popular metaverse worlds can be accessed using your computer, why not check out Decentraland, The Sandbox, Somnium or even Second Life. In most of these worlds, users don’t have to create an account or spend money to start exploring however if you want the full experience then you’ll need to do so.
Entering the metaverse doesn’t cost anything, just like going on the internet doesn’t cost anything – apart from your internet connection and hardware, of course! And don’t forget that if you want a truly immersive 3D experience, then you might want to consider investing in a VR headset.
But, if you do want to access some of the features of the metaverse and invest in some virtual real estate or perhaps buy yourself a Gucci handbag, then you will need to put your hand into your virtual pocket and spend some of your virtual dollars. But the currency you will need depends entirely on the metaverse you are in.
Decentraland’s currency MANA is considered to be the most commonly used currency in the metaverse and also one of the best to invest in, according to some experts. MANA can be used to buy land, purchase avatars, names, wearables, and other items in the Decentraland marketplace.
The Sandbox has a different currency, SAND, which is also used to buy items from The Sandbox marketplace. This is the second most popular currency however be prepared to buy the currency of the world you choose to spend your time in.
Now, I totally appreciate that the whole concept of the Metaverse is a lot to get your head around. But if you have a tribe of kids, then chances are they are going to want to be part of it so don’t put it in the too-hard basket. Take some time to get your head around it: do some more reading, talk to your friends about it and check out some of the metaverses that you can access from your PC. Nothing beats experiencing it for yourself!
In Part 2, I will be sharing my top tips and strategies to help us, parents, successfully guide our kids through the challenges and risks of the metaverse. So watch out for that.
Till, next time – keep researching!

Sextortion is something no parent wants to think could happen to their child, nor a topic most of us would ever imagine we’d need to discuss in our homes. However, according to the latest FBI reports, sextortion is a digital threat to children that, woefully, is on the rise.
According to the FBI, there has been a considerable increase lately in sextortion cases involving children and teens being coerced by adults online.
A sextortion scenario can emerge in several ways. Most often, it occurs when an adult (posing as a peer) engages in casual conversation with an underage child, gains their trust through online conversation, then pressures or threatens the child into sharing sexual photos or videos of themselves.
In some cases, the initial contact with the criminal will be a threat. The person may claim to already have a revealing picture or video of a child that they threaten to share if the victim does not send more pictures.
According to the FBI, this crime more often starts when young people believe they are communicating with someone their age who is interested in a relationship or with someone who is offering something of value. This catfish (false profile) relationship usually involves the predator using gifts, money, flattery, lies, or other methods to get a young person to produce an image.
These dangerous conversations can be initiated through text, a social or chat app, a gaming site, or any number of digital connection points.
After a criminal successfully obtains a photo or video from their victim, the threats can escalate to promises to publish the content or even hurt the child if they don’t send more. This emotionally harrowing situation can ignite shame, fear, and confusion in children who may be too embarrassed to ask for help or report the abuse.
While these criminals rarely request to meet their victims face-to-face, the emotional and physical impact of sextortion can be devastating to a child. According to the FBI, some victims report abusers who become vicious with non-stop harassment and threats. Victims can feel scared, alone, embarrassed, and increasingly desperate. Sadly, as reported in the news, this type of crime can leave some children feeling like they have no way out of the situation.
If you are a parent or caregiver, explain to your child how sextortion can happen to anyone online and why it’s important to only connect with known friends and family. Parents: Consider boosting your device security with parental controls that filter content, report your child’s online activity, and reveal potential problems.
Some essential safety protocols kids should follow online are worthy of repeating. They are:
1) Make social accounts private, don’t share personal information, and only connect with known friends
2) Ignore and block messages from strangers
3) Keep your guard up. People can pretend to be anyone online, and photos can be altered
4) Be suspect if anyone asks you to message or text with them privately
5) Never share risky photos with anyone online—even a trusted friend
6) Tell someone immediately if someone is threatening you online.
With your child, go through their apps, social networks, chats, gaming communities, and friend groups and do some editing, defriending, and blocking. Make sure both you and your child know and trust all their online connections. Remember: Open communication and an honest relationship with your child are the most powerful tools you have to keep your child safe online.
A sextortion situation for a child can be incredibly confusing and cause them to isolate and avoid telling anyone about it. Remind and be clear with your child that they would never be in trouble for coming to you with any problem. Let them know that sextortion is a crime for the perpetrator and that they have not broken any laws by sending photos (despite what an abuser might have told them).
Victims of sextortion should go to a parent or trusted adult and tell them they need help. While doing this can feel terrifying, it’s crucial for victims to know people understand and want to help. For parents and caregivers, contact the FBI at 1-800-CALL-FBI or report the crime online at tips.fbi.gov.
While the bad actors online are out to exploit and ruin our digital spaces, it’s important to maintain a healthy perspective rather than responding with fear. Remind your kids that there’s an army of people even more dedicated than the criminals; people like the FBI who are out to stop online crime and keep the internet safe for families. Additionally, as a parent or caregiver, your commitment to helping your family stay informed, equipped, and empowered online is how we all win.

So much of our personal and professional lives are online — from online banking to connecting with friends and family to unwinding after a long day with our favorite movies and shows. The internet is a pretty convenient place to be! Unfortunately, it can also be a convenient place for cybercriminals and identity theft.
One way these scammers may try to take advantage of someone is by trying to convince them to give up their personal information or click on links that download things like malware. They might try to appear as a trustworthy source or someone you personally know. This fake online communication is called “phishing.”
As we’ve all heard before, knowledge is power. By understanding what phishing is, how it works, and the signs to look for, you can help minimize your risk and get back to enjoying the internet the way it was intended. Here’s what you should know.
You’ve probably heard of the term “phishing,” but maybe you don’t know what it means. Here’s a quick overview of how it works.
Phishing is a type of cybercrime where scammers send communications that appear to be from trusted sources like a major corporation — basically, they’re trying to play off people’s trust through what is known as social engineering. They might request sensitive information like passwords, banking information, and credit card numbers. Hackers may then use this information to access your credit cards or bank accounts.
The thing with phishing attacks, though, is that they can come through several platforms, including:
We’ve mentioned that phishers are looking to get sensitive information, but what exactly are they after? The kind of information phishing scams are after might include:
Phishing scams can come in many forms, but understanding the common types of phishing attacks can help you keep identity thieves at bay. Here are some to be aware of:
A phishing email is a fraudulent email made to look like it’s from a legitimate company or person. It may ask you to provide personal information or click on a link that downloads malware. For example, an email allegedly from Bank of America notes that due to suspicious activity, you should log into your bank account to verify your information.
Fortunately, there are ways to spot a phishing cyberattack like this.
While some phishing emails are sent to a broad audience, spear phishing emails target specific individuals or businesses. This allows the scammers to research the recipient and customize the message to make it look more authentic.
Examples of spear phishing emails include:
One of the best defenses against spear phishing is to contact the source of an email to verify the request. Call the colleague who’s asking you to do a wire transfer or log onto your Amazon account to check for messages.
For this highly customized scam, scammers duplicate a legitimate email you might have previously received and add attachments or malicious links to a fake website. The email then claims to be a resend of the original. Clicking a malicious link can give spammers access to your contact list. Your contacts can then receive a fake email that appears to be from you.
While clone phishing emails look authentic, there are ways to spot them. They include:
Through vishing or voice phishing, scammers call you and try to persuade you to provide sensitive data. They might use caller ID spoofing to make the call appear to be from a local business or even your own telephone number. Vishing calls are usually robocalls that leave a voicemail or prompt you to push buttons for an operator. The intent is to steal credit card information or personal and financial information to be used in identity theft.
Fortunately, there are signs that give away these attacks. They include:
If you’d like to avoid vishing calls, there are several things you can do. When you don’t recognize the number, don’t answer the phone. Let the call go to voicemail, then block it if it isn’t legitimate. Use a call-blocking app to filter calls coming to your cellphone. To block calls on a landline, check with your service provider regarding the services offered.
Dealing with a cybercriminal is no time to be polite. If you do answer a vishing call, hang up as soon as you realize it. Don’t answer any questions, even with a yes or no. Your voice could be recorded and used for identity theft. If they ask you to push a button to be removed from a call list, don’t do it. You’ll just receive more calls.
If you receive a voicemail and are unsure if it’s legitimate, call the company directly using the phone number on the company website. Don’t call the number in the voicemail.
If you’ve ever received a text pretending to be from Amazon or FedEx, you’ve experienced smishing. Scammers use smishing (SMS phishing) messages to get people to click on malicious links with their smartphones. Some examples of common fraudulent text messages include:
If you receive a smishing text, don’t respond because it’ll cause you to receive more texts. Instead, delete the text and block the number.
Pop-up phishing occurs when you’re on a website and a fake pop-up ad appears. It encourages you to click a link or call a number to resolve the issue. Some of these reload repeatedly when you try to close them or freeze your browser.
Common pop-up scams include:
If you see a scam pop-up ad, don’t click on the ad or try to click the close button within the ad. Instead, close out of the browser window. If your browser is frozen, use the task manager to close the program on a PC. On a Mac, click the Apple icon and choose Force Quit.
Being online makes us visible to a lot of other people, including scammers. Fortunately, there are things you can do if you become a victim of phishing — allowing you to get back to enjoying the digital world. They include:
You deserve to live online freely. But that might mean taking steps to protect yourself from phishing attempts. Here are some ways you can improve your cybersecurity and keep scammers at bay:
You don’t have to stop enjoying the internet just because of phishing attempts. McAfee’s identity theft protection services, including antivirus software, make it possible to enjoy your digital world while staying safe from scammers and identity thieves.

In this digital age, communicating online and through our devices has become the norm. From sharing highlights of last night’s game to sending cute animal videos back and forth, so much of our connectedness happens virtually. It’s become so easy to chat with friends and loved ones through social media that we don’t even have to think about it. We know who’s on the other end of the screen, so why would we worry? We know our friends would never send us a malicious link that would steal our information, so why be cautious? Right?
Not necessarily. Though a message or link may seem like it’s coming from a friend, it’s also possible that it was sent without their knowledge. There are many ways for hackers to scam people very believably. The latest Facebook Messenger hack is just one of many examples.
According to PIXM, Facebook users have been conned for several months by a phishing scam that tricks them into handing over their account credentials. Users are shown a fake login page that copies Facebook’s user interface, giving it the illusion of being real. When someone enters their credentials, their password and login combo is sent to the hacker who then sends out the same link and fake login to the user’s friends through Facebook Messenger. Any user who clicks the link is asked to fill out their credentials, and the cycle repeats. PIXM estimates that over 10 million Facebook users have been duped by this scam since 2021.
This hacker was able to utilize a technique to evade Facebook’s security checks. When a user clicks on the link in the Messenger app, the browser redirects to a legitimate app deployment service, then redirects again to the actual phishing pages with advertisements and surveys that accrue revenue for the hacker. Using this legitimate service link prevents Facebook from blocking it without blocking other legitimate apps and links as well. Researchers say that even if Facebook managed to block one of these links, several others are created with new unique IDs every day to replace it.
Phishing scams like these are harder to detect due to the realistic-looking interface on the login pages and that these malicious links are seemingly coming from friends and family. However, there are always key things to look out for when faced with phishing scams.
Scams don’t always come from overtly sketchy emails or text messages from strangers. Sometimes they can (unintentionally) come from people we know personally. This isn’t to say that your friends online can’t be trusted! However, it’s important to always be cautious and keep an eye out for any odd behavior to stay on the safe side. Here are some key things to look out for when faced with potential malicious phishing scams:
When in doubt, just ask! If you’ve received a message and a link from a friend online, simply ask if they meant to send it to you. If they didn’t send it themselves, not only did you dodge a bullet, but your friend is also now aware that they’ve been hacked and can take the necessary precautions to ensure their information is protected. And if they did mean to send it to you, then you can click the link knowing that it’s safe to do so. It’s always best to err on the side of caution when it comes to your online security.

It’s Social Media Day! How are you celebrating? Reposting your very first profile picture from a decade ago? Sharing your most-loved status update or the photo you’re most proud of? This year, consider commemorating the day by learning more about how to keep your information safe. Enjoy your favorite platform, but be on the lookout for scams, such as social engineering.
Social engineering is a cybercrime common to social media sites. It is a tactic where a cybercriminal lurks on people’s social media pages, gleaning personal information that they then use to impersonate them elsewhere.
With more than half of the global population on social media, you may think that a cybercriminal will never single you out from such a huge pool; however, it is possible.1 Luckily, you only have to make a few, easy changes to your online habits to keep your valuable private information just that: private. Check out these tips to make smart decisions and be more confident about your and your family’s online security.
Think of the types of posts you share with your dozens – or even hundreds or thousands! – of followers: updates about your life, where you live, work, or favorite travel destinations, your hobbies, pets, family members, etc. All of these details, that only you and those closest to you should know, are a valuable commodity to cybercriminals. Plus, now that social media shopping is growing in popularity, the credit card information linked to accounts is sweetening the deal for cybercriminals.
Here are a few social engineering scams that are common to social media.
People commonly create passwords based on things, places, and people that are important. Have you ever published a 20 questions-style get-to-know-me post? Those contain a lot of valuable personally identifiable information (PII). With just a few of those details about your personal life, cybercriminals can make educated guesses at your passwords, a tactic called credential stuffing. If they’re able to crack the code to one of your accounts, they’ll then input that password and login variations in several other sites, especially online banking portals, to see if they can gain entry to those too.
You’ve won! Send us your banking information and address, and you’ll receive a package in the mail or a direct deposit to your bank account!
But did you enter a drawing for a prize? Very rarely does anyone win something just by being a follower of a certain page. If you receive a message similar to the above, it’s likely a phisher trying to draw more PII and sensitive banking information out of you. Or, the message may have links within it that redirect to an untrustworthy site. If you regularly enter social media contests, keep a list and only respond to legitimate ones. Also, never give your banking information out over social media, private messages, or email.
There are plenty of valid fundraisers and petitions circulating around social media; however, there are just as many social engineering scams that dupe social media users because they inspire a strong emotion in them. For example, there have been several scams around Ukrainian donation sites. Cybercriminals often use fear, anger, or sadness to inspire people to open their wallets and share confidential banking information.
Luckily, all it takes is a few smart habits to stop social engineers in their tracks. Consider the following tips and make these small changes to your social media usage:
At this point, you’ve probably had several of your social media accounts active for over a decade. That means it’s time to do some cleaning out of your friends and followers lists. It’s best to only accept requests from people you personally know and would actually like to keep in the loop about your life. A friend and follower request from strangers could be cyber criminals in disguise. Also, consider setting your account to private so that your posts are invisible to strangers.
Social engineering hacks often bank on people acting rashly and quickly because of strong emotion, either excitement, fear, sadness, or anger. If you see a post on your newsfeed or receive a direct message that gives you a tight window to respond and asks for PII, slow down and think before acting. Double-check the destination of every link in the message by hovering over it with your cursor and checking the link preview at the bottom of your browser screen. Be careful, because some link previews include slight misspellings of legitimate websites. As a great rule of thumb, be automatically skeptical of direct messages from people you do not personally know. And if a DM from a friend seems out of the ordinary, shoot them a text to confirm they actually sent it. It could be that their social media account was hacked and a criminal is spamming their followers.
A password manager will go a long way toward ensuring you have unique, strong passwords and passphrases for every account. Not reusing passwords makes credential stuffing impossible. McAfee True Key stores all your logins and passwords and guards them with one of the strongest encryption algorithms available. All you need to do is remember your master password. It’s a great practice to also enable multifactor authentication whenever a website offers it. This makes it incredibly difficult for a cybercriminal to break into your online accounts with their educated guesses at your password.
Now that you know what to look for and the best tricks to be safe, you can feel more confident that you’re doing everything you can to protect your online accounts and private information. McAfee Protection Score can also help you take control of your online safety. This service allows you to monitor your current online safety and encourages you to take specific steps to improve it. Now you can enjoy digitally keeping in touch with your friends with peace of mind!

Say you’re getting married. You and your partner have booked the venue, made the seating arrangements, trained your dog to be the ring bearer – and everything is running smoothly. You’ve used a trusty wedding planning website to make everything a breeze. Nothing could ruin this day for you! Except, there’s an uninvited guest. They’re not crashing the wedding and making an awkward toast, but they’ve crashed into your wedding planning website account and now have access to your information.
There are many things that could go wrong during wedding planning – some of them out of anyone’s control. Maybe the caterer canceled last minute, or the live band is stuck in traffic. Other things may be easily avoided, but you don’t necessarily see them coming. Like a hacker accessing your wedding website and making fraudulent bank transfers right before your big day.
Zola, a wedding planning site allowing couples to create websites, budgets, and gift registries, confirmed that hackers had managed to access the accounts of some of their users, The Verge reported. Once these accounts were infiltrated, hackers used the linked bank accounts or funds held inside the site to make cash transfers. The main method these cybercriminals used was purchasing gift cards through the user’s account and sending them to their email addresses to avoid being easily traced.
These criminals did not hack the Zola website itself but hacked their users’ accounts with a method called credential stuffing. This is a strategy where hackers take email and password combinations involved in previous breaches of other websites and use them to log into other online profiles.
You may not even know that your information had been breached previously and that cybercriminals now had your logins for a number of different accounts. Luckily, there are ways to protect yourself and your information from credential stuffing tactics to stop hackers in their tracks.
Just because you’ve hypothetically grown up and are ready for lifelong commitments doesn’t mean you’ve outgrown those old trusty email addresses and passwords (hello, “basketball4life23”). There’s a level of nostalgia that comes with using the email account that you made in middle school, or maybe you just haven’t gotten around to changing it. However, keeping those old email addresses and logins are doing you more harm than good. Want to make sure that hackers aren’t able to credential stuff your accounts? Here are some trusty tips to keep your information safe.
The best way to know that your old accounts aren’t coming back to haunt you is to make sure those ancient logins are dead and gone. If you don’t remember all the accounts you’ve made and no longer use, don’t sweat it! There are settings through your internet browser that will show you all the accounts and passwords you have saved. A password manager also keeps track of all your credentials, so you don’t have to wrack your brain to try and remember every account you’ve ever made. Once you’ve gone through all your old online accounts you no longer use, close them for good! Though this step will require some time and patience, it’s always better to put in the effort and know your information is safe than to risk it.
Only having to remember one password for every account may make logging in easier, but ensuring that each of your accounts is unique and secure is worth the extra effort. Having a strong and unique password for each of your accounts helps protect them from credential stuffing and other threats. Varying your passwords across online accounts will assure you that if one of them is breached, the others will remain safe. A password manager can also help with this step, because many of them, such as True Key, can generate strong, random, and unique passwords for every account.
Keep an eye out to make sure that if a website or company you have an account with is breached, you are updating your credentials so that hackers can’t access them. If you see that there has been a hack and your information is vulnerable, immediately update your logins and passwords on that account to keep yourself safe.
Using multifactor authentication adds an extra layer of protection to your accounts. This safety measure requires more than one method of identity verification to access the account, helping to prevent criminals from gaining access to your password-protected information.
Don’t let cybercriminals get the jump on you! Take the necessary steps to protect your accounts and your personal information. Though combing through your old accounts and deleting them or coming up with a new and unique password for every site login isn’t a glamourous activity, you’ll enjoy greater peace of mind that your accounts are safe, leaving you free to enjoy life’s best moments.

So is your smart speaker really listening in on your conversations?
That’s the crux of a popular privacy topic. Namely, are we giving up some of our privacy in exchange for the convenience of a smart speaker that does our bidding with the sound of our voice? After all, you’re using it to do everything from search for music, order online, and control the lights and temperature in your home.
What is your smart speaker really hearing—and recording?
Let’s take a look at what’s going on inside of your smart speaker, how it processes your requests, and what companies do with the recordings and transcripts of your voice.
More or less, smart speakers are listening to all the time. Each smart speaker has its own “wake word” that it listens for, like Alexa, Siri, or Google. When the device hears that wake word or thinks it hears it, it begins recording and awaits your verbal commands. Unless you have the microphone or listening feature turned off, your device indeed actively listens for that wake word all the time.
Here’s where things get interesting, though. There’s a difference between “listening” and “recording.” The act of listening is passive. Your smart speaker is waiting to hear its name. That’s it. Once it does hear its name, it begins recording for a few seconds to record your command. From there, your spoken command goes into the company’s cloud for processing by way of an encrypted connection.
There are exceptions to when your command may go to the company’s cloud for processing, like Siri on iPhones, which according to Apple, “You don’t sign in with your Apple ID to use Siri, and the audio of your requests is processed entirely on your iPhone.” Also, Google Assistant may process some requests without going to the cloud, like “When a user triggers a smart home Action that has a local fulfillment path, Assistant sends the EXECUTE intent or QUERY intent to the Google Home or Google Nest device rather than the cloud fulfillment.”
In the cases where information does go to the cloud, processing entails a few things. First, it makes sure that the wake word was heard. If it’s determined that the wake word was indeed spoken (or something close enough to it—more on that in a minute), the speaker follows through on the request or command. Depending on your settings, that activity may get stored in your account history, whether as a voice recording, transcript, or both. If the wake word was not detected, processing ends at that point.
Enter the issue of mistaken wake words. While language models and processing technologies used by smart speakers are constantly evolving, there are occasions where a smart speaker acts as if a wake word was heard when it simply wasn’t said. Several studies on the topic have been published in recent years. In the case of research from Northeastern University, it was found that dialogue from popular television shows could be interpreted as wake words that trigger recording. For example, their findings cite:
“We then looked at other shows with a similarly high dialogue density (such as Gilmore Girls and The Office) and found that they also have a high number of activations, which suggests that the number of activations is at least in part related to the density of dialogue. However, we have also noticed that if we consider just the amount of dialogue (in a number of words), Narcos is the one that triggers the most activations, even if it has the lowest dialogue density.”
Of interest is not just the volume of dialogue, but the pronunciation of the dialogue:
“We investigated the actual dialogue that produced Narcos‘ activations and we have seen that it was mostly Spanish dialogue and poorly pronounced English dialogue. This suggests that, in general, words that are not pronounced clearly may lead to more unwanted activations.”
Research such as this suggests that smart speakers at the time had room for improvement when it comes to properly detect wake words, thus leading to parts of conversation being recorded without the owner intending it. If you own a smart speaker, I wouldn’t be too surprised to hear that you’ve had some issues like that from time to time yourself.
As mentioned above, the makers of smart speakers make constant improvements to their devices and services, which may include the review of commands from users to make sure they are interpreted correctly. There are typically two types of review—machine and human. As the names suggest, a machine review is a digital analysis and human reviews entail someone listening to and evaluating a recorded command or reading and evaluating a transcript of a written command.
However, several manufacturers let you exercise some control over that. In fact, you’ll find that they post a fair share of articles about this collection and review process, along with your choices for opting in or out as you wish:
The quickest way to ensure a more private experience with your smart speaker is to disable listening—or turn it off entirely. Depending on the device, you may be able to do this with the push of a button, a voice command, or some combination of the two. This will keep the device from listening for its wake word. Likewise, this makes your smart speaker unresponsive to voice commands until you enable them again. This approach works well if you decide there are certain stretches of the day where your smart speaker doesn’t need to be on call.
Yet let’s face it, the whole idea of a smart speaker is to have it on and ready to take your requests. For those stretches where you leave it on, there’s another step you can take to shore up your privacy.
In addition to making sure you’re opted out of the review process mentioned above, you can also delete your recordings associated with your voice commands.
Managing your voice history like this gives you yet one more way you can take control of your privacy. In many ways, it’s like deleting your search history from your browser. And when you consider just how much activity and how many queries your smart speaker may see over the course of days, weeks, and months, you can imagine just how much information that captures about you and your family. Some of it is undoubtedly personal. Deleting that history can help protect your privacy in the event that information ever gets breached or somehow ends up in the hands of a bad actor.
Lastly, above and beyond these privacy tips for your smart speakers, comprehensive online protection will help you look out for your privacy overall. In the case of ours, we provide a full range of privacy and device protection, along with identity theft protection that includes $1M identity theft coverage, identity monitoring, and identity restoration assistance from recovery pros—and antivirus too, of course. Together, they can make your time spent online far more secure.
You’re the smart one in this relationship
With privacy becoming an increasingly hot topic (rightfully so!), several companies have been taking steps to make the process of managing yours easier and a more prevalent part of their digital experience. As you can see, there are several ways you can take charge of how your smart speaker uses, and doesn’t use, your voice.
It used to be that many of these settings were tucked away deep in menus, rather than something companies would tout on web pages dedicated to privacy. So as far as smart speakers go, the information is out there, and I hope this article helps make the experience with yours more private and secure.

Cryptocurrency is all the rage these days and it doesn’t seem to be slowing down any time soon. As more people dive into the nitty-gritty of what blockchain is, how NFTs are traded, and the difference between Bitcoin and Ethereum, digital currency developers are finding new ways for people to engage with crypto. But as crypto continues to grow and become more profitable, hackers are simultaneously trying to find ways to get their hands on the coins.
According to Markets Insider, one of the biggest crypto heists in history took place recently, resulting in roughly $625 million stolen.1 Here’s what you need to know about this crypto theft, and how you can stay protected when investing in digital assets.
Ronin, the blockchain underlying the play-to-earn crypto game Axie Infinity, revealed that a hacker stole 173,600 Ethereum (currently worth around $600 million) and 25.2 million USDC (a cryptocurrency pegged to the U.S. dollar), resulting in a loss of about $625 million in cryptocurrency.
On March 29th, Ronin and Axie Infinity operator Sky Mavis revealed the breach and froze transactions on the Ronin bridge, which allows depositing and withdrawing funds from the company’s blockchain. This “side chain” contained nine validator nodes, or proof-of-stake tools, that confirmed and approved each transaction. At least five validator nodes are needed to approve each transaction. Sky Mavis oversaw five, and Axie Decentralized Autonomous Organization (or DAO) controlled four. However, Sky Mavis discontinued its agreement with the DAO in December but failed to revoke the DAO’s permissions. Due to this oversight, the hacker was able to take over the necessary amount of validator nodes to enable access to the cryptocurrency and make a break with it.
According to experts, the use of these side chains rather than native blockchains leads to a rise in cryptocurrency vulnerabilities. Had Sky Mavis abandoned the side chains and stuck to the blockchains, it is likely that an attack of this magnitude could have been avoided. Rather than a cryptocurrency issue, this is more of a cybersecurity issue.
If you are interested in getting into crypto, don’t let cyberattacks like this deter you! As a fairly new phenomenon, there are still many ways in which the crypto world needs to grow, adjust, and adapt to ensure that users can interact with it safely. In the meantime, if you are wanting to dive into the crypto economy but still have reservations, here are some tips to help you stay protected:
Whenever you decide to dive into something new, it’s always important to make sure you are knowledgeable about that thing, especially if it involves investing your money. Before jumping right into the crypto world, research each cryptocurrency, each blockchain, and any software you may use. Keep up with the news to stay informed on security breaches and pick up tips for which system you may want to engage in. Knowing the ins and outs of the crypto economy and its security protocols will solidify your decision of whether you want to join the crypto community and whether the benefits outweigh the risks.
As with all online accounts, it’s important to use secure, unique passwords and two-factor authentication when creating and maintaining cryptocurrency logins. Hackers can access lists of passwords and logins via the dark web, so never reuse your passwords. Two-factor authentication requires a randomly generated passcode for entry that is only accessible to you, so cybercriminals will not be able to access your accounts. If your accounts are a pain for a hacker to try to get through, they will likely move on, keeping your account, your information, and your assets safe.
For some added protection, store your assets in a crypto wallet. A crypto wallet is a software product or physical device that stores the keys to your cryptocurrency accounts. Crypto wallets allow you to transfer funds between crypto types and make transactions while keeping your investments protected. There are various types of cryptocurrency wallets, so do your research to find which one is best for you and your accounts.
Develop a routine of checking in on your crypto accounts to keep an eye on any suspicious transactions. Keep up with news outlets so that if there does happen to be a breach, you can make a timely report of any losses you may have had. For some added security and protection, consider changing your login credentials.
Hackers often use social engineering to enact cyberattacks like these. This includes targeting users’ emails or using phishing to gain access to these accounts. When receiving emails, be wary of addresses that seem slightly off, odd spelling and grammar mistakes, and any links or attachments added to the message. Being cautious and alert when you are online is an important step to ensuring your account safety.
As the world of crypto continues to evolve and more people get involved, cybercriminals are itching to take advantage. However, that is no reason to avoid getting into the crypto economy. If you decide to try your hand at digital currencies, make sure you are doing your research, staying up to date on what is happening in the crypto news, and remaining vigilant when it comes to your online safety.
The post $625 Million Stolen in Latest Crypto Attack: 5 Tips on How to Use Digital Currency Safely appeared first on McAfee Blog.
What’s worse than a surprise call from a law enforcement official telling you to pay a fine or be forced to serve time? Providing your personal information and paying that fine only to find out that it was all a scam. You didn’t miss jury duty; you didn’t commit a crime — you were just tricked into thinking that you did.
Sound unbelievable? It’s more likely than you’d think.
According to ZDNet1, the FBI released a warning about scammers impersonating government officials or law enforcement agencies to steal personal information and money from unsuspecting people.
After acquiring phone numbers and names from real users, scammers use fake credentials from well-known law enforcement agencies to contact victims. Under the guise of these officials, scammers claim that the user’s identity was used in a crime and ask them to provide their social security number and date of birth for verification. The fraudsters will also call or text about apparently missed jury duty, missed court dates, warrants out for arrest, or other local fines that require payment to be solved.
These criminals demand payment in multiple forms, but the most common are prepaid cards, wire transfers, and cash sent through mail or through cryptocurrency ATMs. If victims do not pay these fines or provide their personal information, the scammers in disguise will threaten them with potential prosecution or arrest.
The FBI states that no law enforcement agency will ever contact you asking for money, but if you’re still unsure whether you’re being scammed, here are a few more phishing tips that can help:
Unsolicited phone calls or texts are best avoided altogether or confirmed with a second source. Verify the caller’s identity with the organization they claim they represent. Ask for a name and position and make it clear you will be following up to verify their identity.
Do not reveal any personal or financial information over the phone, through text, or through a link provided in a text message.
Generic greetings that do not address you by name, especially when asking you to verify your identity or pay a fine, are a definite indicator that you may be being scammed.
Any strange grammar or spelling mistakes in a text message can be signs that this is someone impersonating an official agency, company, or higher-up to scam you.
Although scammers try to trick users over the phone, phishing scams can also happen over email. In addition to the tactics mentioned above, here are some extra tips on how to detect and avoid phishing emails:
Cybercriminals will often impersonate well-known brands or individuals by using fraudulent email addresses with just a few alterations of letters or characters. An example is an email address that appears as “bank0famerica.con.”
If you receive a message or email with a link, hover over the link without clicking on it. This will allow you to see a link preview. If the URL looks suspicious or doesn’t match up with the content in the email, do not interact with it and delete the entire message.
Be cautious of any attachment in an email. Scammers often use attachments as a sneaky way to deliver viruses and malware onto unsuspecting people’s devices.
Phishing scams can be deceitful, especially with the added pressure of a seemingly real (but definitely fake) government official or law enforcement agency accusing you of breaking the law. However, by following the tips outlined above, you’ll be able to spot these scams from a mile away and stay safer online!

As a gamer, you love the stuff you’ve racked up over the years—that rare Fortnite skin from six seasons ago, a complete set of Tier 20 armor in World of Warcraft, or a Steam account loaded with your favorite titles. Hackers love it too. Because they can make money off it.
Hackers have been stealing and reselling online gaming accounts for some time now. Yet the recent 400 percent rise in online gaming theft shouldn’t come as a surprise, particularly as so many of us turned to games for entertainment lately. As people leveled up, gathered loot, and filled their libraries with games in the cloud, hackers saw the opportunity.
The opportunity is this: gaming accounts have a street value. The virtual items and perks we acquire through gaming take time, effort, participation, and sometimes just good luck to build up. In a way, we’ve worked hard to earn our fun. Meanwhile, others out there are willing to take a shortcut. There are those who’ll pay for a well-stocked gaming account that someone else has built up, and hackers are more than willing to hijack accounts from innocent victims and sell them online.
Put simply, the virtual goods in your gaming accounts are like any other good. They have value. And just like anything else you value, they’re worth protecting. That’s exactly what we’ll help you do here.
First up, let’s take a quick look at the different ways digital goods get moved and sold out there—just to get a sense of the marketplaces that have cropped up around gaming and where hackers fit into the mix.
And there are several. Over the years we’ve seen all kinds of gaming marketplaces crop up, whether they’re sanctioned marketplaces built inside of online games, gray marketplaces that exist outside of games, and dark marketplaces where stolen accounts and goods are exchanged.
As a gamer, you’re likely familiar with any number of sanctioned auction houses and marketplaces that are built right into online games, all designed and supported by the game’s developers. A classic example is the long-running auction house in World of Warcraft where players can buy and sell items with in-game currency, the World of Warcraft gold piece. And as marketplaces can go, the rarer and more coveted the item, the higher the price the seller can get for it. In fact, there are plenty of articles on how to play the markets for profit, in a quasi-stock market-like fashion, and all within the legitimate boundaries of the game.
In recent years, we’ve also seen the rise of in-game currencies that players can purchase for cash, again by design and with the support of the developer. A couple of examples are the World of Warcraft Tokens and Minecraft tokens and coins. What you can do with such tokens and coins varies from game to game, yet players can use them to acquire in-game currency, items, or paid to play time.
Increasingly common are in-game stores that allow players to purchase items and perks with cash, just like any other online store. Taken together with all the other ways a player can round up items in a game, it’s easy to see how a gamer’s account can grow into something somewhat unique and valuable over time, simply by playing and participating in the game.
With the time it takes for a player to level up a powerful character and acquire the items that can come along with it, there are out-of-game organizations that will, for a fee, do that work for a player in return for payment. Essentially it involves a player starting a gaming account, rolling up a character, and then handing over the account to a “booster” who will play the game on the owner’s behalf. When the agreed-upon level is reached, the booster hands back the character to the owner.
Of course, there are all kinds of potential problems with this. Strictly from a security standpoint, this means an account owner is handing over their credentials to a stranger, with no real guarantee that this stranger simply won’t change the account password, never hand back the account, and simply walk away with any funds that may have been paid upfront.
Further, “boosting” and other similar services may be against the user agreement the player signed when joining up for the game. For example, World of Warcraft recently updated its policy, stating that they now,
[P]rohibit organizations who offer boosting, matchmaking, escrow, or other non-traditional services, including those offered for gold. World of Warcraft accounts found to be in violation of this policy are subject to account actions. These actions can include warnings, account suspensions and, if necessary, permanent closure of the disruptive World of Warcraft account(s).
So while “boosting” services may not be illegal themselves, they can run counter to user agreements and may lead to cases of fraud when a booster service fails to fulfill its commitment or simply locks a player out of their own account.
Then there’s the theft and resale of online game accounts, clear examples of digital goods illegally changing hands. Stolen accounts make their way into dark web marketplaces and ads on chat platforms and social media, thanks to hackers who’ve cracked previously legitimate accounts and then packaged them up for sale. In some instances, cybercriminals will sell entire game collections, such as online gaming platform accounts where gamers may have purchased and have access to dozens and dozens of games stored in the cloud.
The method behind this theft is much like a credit card or bank account hack. Often using credentials lifted from a data breach, hackers will take known usernames and passwords and feed them into a credential stuffing application—which can then attempt to access hundreds, even thousands, of accounts through automated login requests.
Given that many users out there use the same passwords across their accounts makes them an easy target for this practice and can reap a large harvest of cracked accounts. From there, the account can be accessed, have its password changed, and then made ready for advertising and sale, where an account can be resold for a few dollars, or for potentially thousands depending on what the account contains.
There’s plenty you can do. A few simple steps on your part can drop some serious roadblocks in the way of a hacker who’s looking to crack your account or target you for a scam.
Each of your accounts should have its own strong, unique password. No repeats. And if you have some sixty-plus accounts across all the shopping, banking, gaming, and forum posting you do, not to mention your apps, that sounds like a lot of work. Because it is. Although it doesn’t have to be. A password manager can do the work for you by creating and storing strong, unique passwords for you.
Data breaches happen all the time now, striking businesses both large and small. If a business or organization where you have an online account gets breached, change your password right away. Related to the above, make sure the passwords across your other accounts are strong and unique. It’s not uncommon for hackers to try breaching passwords in other accounts, all in the hope that the victim is using the same or a similar password on other accounts as well.
Several gaming services offer multi-factor authentication (MFA) as a means of protecting accounts. In addition to requiring a username and password to log in, MFA further verifies account activity by sending a unique code to the email address or text to a device you own, which makes gaining illegal access that much tougher for hackers. Some gaming platforms even support an authentication app, such as the Battle.net Authenticator, offered by Blizzard. In all, the occasional extra clicks required by MFA can really save you some massive headaches by preventing theft. If you have MFA as an option, strongly consider using it.
Phishing attacks have made the jump from email to bogus ads on social media and in search too. In short, a phishing attack involves the hacker posing as a well-known company or organization with the intent of fooling you into providing your username and password. With that, they can drain your account, whether it’s money from your bank account or goods in your gaming account. Spotting phishing attacks can call for a sharp eye nowadays because some hackers can make the phishing emails and sites they use look like the real thing. Comprehensive online protection software will include web protection that can spot bogus links and sites and warn you away from them, even if they look legit.
Spearphishers are a special sort, in that they make more targeted attacks. While a phisher will send out an email blast or attempt to rope in a high volume of victims with an ad, a spearphisher will send a direct message to specific, potential victims. You may have seen or heard of this in massively multiplayer online games where an otherwise unknown player sends a message to another with a link to a website, complete with the promise of loot, in-game currency, or services to level up characters. Ignore and don’t visit that link. Chances are it’s a scammer, or at least someone who may be breaking the game’s user agreement by offering such services.
Whether you’re downloading a mod, an expansion, or a new game itself, go with a reputable online store or source. Hackers will drop malware into all kinds of files and applications, games included. Given that such malware could log keystrokes that steal login info, inject ransomware code to hold your device and data hostage, or simply wreak havoc on your files and things, it can have implications for more than just your gaming accounts and the virtual assets you have with them.
Hackers know there’s good money in gaming accounts. They wouldn’t bother with them otherwise. Realizing that your gaming account has value is the first step to protecting it.
In addition to taking the steps above, consider comprehensive online protection software. It offers defense in breadth and depth, covering everything from device security, privacy, and identity protection. However, if you want an even faster and safer gaming experience, gamer security is worth looking into. In addition to strong security features, it also offers performance-enhancing technologies that prioritize system resources and keep your gameplay going smooth.
In all, keep in mind that gaming accounts are serious business for hackers. Put up your defenses. Then get out and enjoy yourself, knowing that you have made it far, far tougher for them to ruin your fun.

It’s the month of top seeds, big upsets, and Cinderella runs by the underdogs. With March Madness basketball cranking up, a fair share of online betting will sure to follow—along with online betting scams.
Since a U.S. Supreme Court ruling in 2018, individual states can determine their own laws for sports betting. Soon after, states leaped at the opportunity to legalize it in some form or other. Today, 30 states and the District of Columbia have “live and legal” sports betting, meaning that people can bet on single-game sports through a retail or online sportsbook or combination of the two in their state.
If you’re a sports fan, this news has probably been hard to miss. Or at least the outcome of it all has been hard to miss. Commercials and signage in and around games promote several major online betting platforms. Ads have naturally made their way online too, complete with all kinds of promo offers to encourage people to get in on the action. However, that’s also opened the door for scammers who’re looking to take advantage of people looking to make a bet online, according to the Better Business Bureau (BBB). Often through shady or outright phony betting sites.
Let’s take a look at the online sports betting landscape, some of the scams that are cropping up, and some things you can do to make a safer bet this March or any time.
Among the 30 states that have “live and legal” sports betting, 19 offer online betting, a number that will likely grow given various state legislation that’s either been introduced or will be introduced soon.
If you’re curious about what’s available in your state, this interactive map shows the status of sports betting on a state-by-state level. Further, clicking on an individual state on the map will give you yet more specifics, such as the names of retail sportsbooks and online betting services that are legal in the state. For anyone looking to place a bet, this is a good place to start. This is further helpful for people who’re looking to get into online sports betting for the first time and is the sort of homework that the BBB advises people to do before placing a sports bet online. In their words, you can consider these sportsbooks to be “white-labeled” by your state’s gaming commission.
However, the BBB stresses that people should be aware that the terms and conditions associated with online sports betting will vary from service to service, as will the promotions that they offer. The BBB accordingly advises people to closely read these terms, conditions and offers. For one, “Gambling companies can restrict a user’s activity,” meaning that they can freeze accounts and the funds associated with them based on their terms and conditions. Also, the BBB cautions people about those promo offers that are often heavily advertised, “[L]ike any sales pitch, these can be deceptive. Be sure to read the fine print carefully.”
Where do scammers enter the mix? The BBB points to the rise of consumer complaints around bogus betting sites:
“You place a bet, and, at first, everything seems normal. But as soon as you try to cash out your winnings, you find you can’t withdraw a cent. Scammers will make up various excuses. For example, they may claim technical issues or insist on additional identity verification. In other cases, they may require you to deposit even more money before you can withdraw your winnings. Whatever you do, you’ll never be able to get your money off the site. And any personal information you shared is now in the hands of scam artists.”
If there’s a good reason you should stick to the “white labeled” sites that are approved by your state’s gaming commission, this is it. Take a pass on any online ads that promote betting sites, particularly if they roll out big and almost too-good-to-be-true offers. These may lead you to shady or bogus sites. Instead, visit the ones that are approved in your state by typing in their address directly into your browser.
In addition to what we mentioned above, there are several other things you can do to make your betting safer.
In addition to choosing a state-approved option, check out the organization’s BBB listing at BBB.org. Here you can get a snapshot of customer ratings, complaints registered against the organization, and the organization’s response to the complaints, along with its BBB rating, if it has one. Doing a little reading here can be enlightening, giving you a sense of what issues arise and how the organization has historically addressed them. For example, you may see a common complaint and how it’s commonly resolved. You may also see where the organization has simply chosen not to respond, all of which can shape your decision whether to bet with them or not.
Credit cards are a good way to go. One reason why is the Fair Credit Billing Act, which offers protection against fraudulent charges on credit cards by giving you the right to dispute charges over $50 for goods and services that were never delivered or otherwise billed incorrectly. Your credit card companies may have their own policies that improve upon the Fair Credit Billing Act as well. Debit cards don’t get the same protection under the Act.
Comprehensive online protection software will defend you against the latest virus, malware, spyware, and ransomware attacks plus further protect your privacy and identity. In addition to this, it can also provide strong password protection by generating and automatically storing complex passwords to keep your credentials safer from hackers and crooks who may try to force their way into your accounts. And, specific to betting sites, online protection can help prevent you from clicking links to known or suspected malicious sites.
With online betting cropping up in more and more states for more and more people, awareness of how it works and how scammers have set up their presence within it becomes increasingly important. Research is key, such as knowing who the state-approved sportsbooks and services are, what types of betting are allowed, and where. By sticking to these white-label offerings and reading the fine print in terms, conditions, and promo offers, people can make online betting safer and more enjoyable.
Editor’s Note:
If gambling is a problem for you or someone you know, you can seek assistance from a qualified service or professional. Several states have their own helplines, and nationally you can reach out to resources like http://www.gamblersanonymous.org/ or https://www.ncpgambling.org/help-treatment/.

A-list celebrities and social media influencers are now adding their voices to the roar of other cryptocurrency fans asking you to join them in the investments of the future. It’s impossible to deny the grip cryptocurrencies have on the world today, for better or worse. In some industries, they speed the pace of business and for some, it’s a viable way to make ends meet and set up long-term investments. The cryptocurrency realm has also proven to be vulnerable to cybercriminals. For example, the Wormhole hack leaked $320 million, and cybercriminals have targeted crypto platforms with ransomware and mining app scams.
Whether you’re already in the cryptocurrency game or are thinking about taking the plunge, here’s what you need to know about crypto wallets and tips on how to keep yours safe from cybercriminals.
A cryptocurrency wallet, or crypto wallet, is a software product or a physical device that stores the public and private keys to your cryptocurrency accounts. Keys are strings of numbers and letters that encrypt and decrypt crypto transactions and secure crypto accounts. You can think of public keys as the routing and account numbers that appear at the bottom of paper checks. There’s not much a nefarious character can do with that information, and it’s totally normal to give that information to an acquaintance with whom you’re doing business. Private keys are like your online banking password or debit PIN. Those you must guard very closely because in the wrong hands, your hard-earned bank balance could disappear. A crypto wallet also allows you to transfer funds between crypto types and make transactions.
Here are a few basic types of crypto wallets to help you decide which type is right for you.
A non-custodial wallet means that you are the sole keeper of the keys to your crypto assets. If you forget your password, there’s no “forgot your password?” prompt to let you back in. While not having this safety net is a little nerve wracking, noncustodial wallets are considered the more secure option. You don’t have to worry about a security breach of a major corporation leaking your private key. If you’re responsible and confident that you’re prepared to look after your assets by yourself, this may be the best option for you.
A custodial wallet is a little less secure, but you have a third party helping you log in and manage your crypto accounts. Custodial wallets are often web-based, and the biggest tick in their pro column is that they’re generally very easy to use. While reputable custodial wallets take security very seriously, the threat of a breach is always a possibility, especially as crypto accounts are appealing targets to cybercriminals.
Hardware wallets, also known as cold wallets, are devices you can fit in the palm of your hand. Most models are Bluetooth-enabled devices that look like small remote controls or are flash drives. The device is secured by a PIN that you should never write down or share with anyone else. Also, you should designate a safe and private spot to store your hardware wallet. Similar to a noncustodial wallet, you are solely responsible for keeping track of the device and remembering the PIN. If you lose it, your crypto accounts are locked, and there’s no locksmith to open them for you. As long as you keep track of it, hardware wallets are very secure. Most models are equipped with malware- and virus-proofing security features.
Software wallets are downloaded and internet-connected mobile or desktop apps. They allow you to make transactions on the run, as you can access your crypto accounts from your phone. In that sense, they’re more convenient than hardware wallets. Additionally, software wallets have the same safety net as custodial wallets: if you lose your phone, forget your password, or require login assistance, the maker of the software can help you access your accounts. Software wallets are very secure when you enable their two-factor authentication login settings; however, since they connect to the internet, there’s always a chance a cybercriminal could break-in. Thus, hardware wallets are considered more secure than the software variety.
Check out these tips to ensure your assets are safe and secure in your crypto wallet:
Cryptocurrency value is reaching galactic heights like the spaceships depicted in prime-time ads. Don’t feel pressured to hop aboard the crypto rocket, but if you do decide to jump on, make sure you do your research carefully and make the best decisions for your crypto goals.

Whether it’s for routine care, a prescription refill, or a simple follow-up, online doctor visits offer tremendous benefits in terms of both convenience and ease of care—all good reasons to help mom and dad get connected with it.
There’s no doubt that more older adults than ever are taking advantage of online doctor visits, more formally known as telemedicine. While usage numbers have risen dramatically across all age groups, it’s particularly so for elders. Pre- and post-pandemic numbers saw a 63-fold increase in Medicare telemedicine use.
However, many older patients are missing out and not using telemedicine for one reason or another. What’s holding them back? Several things, according to research from the University of California, San Francisco:
Moreover, another issue is that many older adults do not know that telemedicine is an option. Research from the University of Michigan showed that 55% of older adults surveyed were unaware if their healthcare provider even offered telemedicine as a service. And perhaps quite telling is that the same survey revealed nearly half of older adults harbored concerns about privacy and did not feel personally connected to their care provider during their visits.
For us as children and grandchildren of older adults, it can be tough knowing that a loved one is missing out on an avenue of care that they could otherwise benefit from. While we absolutely respect what they feel is comfortable and trustworthy for them, there are several other areas where we can help the older loved ones in our lives overcome the issues and concerns they face.
With that, let’s talk about the technology behind telemedicine and how you can help them use it, and address some of those privacy issues as well.
As indicated above, paying a visit to the doctor via telemedicine can be a big jump. Just as the idea of it is new for many of us, it’s yet newer for older adults. There’s a good chance that you’re familiar with video chats and calls already, which gives you a foundation we can work with when it’s time to see the doctor on a screen. That may not be the case for older adults. Add that into the privacy concerns and decades of seeing a doctor in person, you can see why some older adults simply choose to opt-out.
One way you can help is to have a few video chats with your older loved ones. In addition to the regular calls you make, you might want to try having a video chat with them from time to time. It’s an outstanding way to spend time together when you can’t be together in person, and it may develop a comfort level with the technology so that they may be willing to give telemedicine a try. You can check out my earlier article in this series that covers video chats with mom and dad, along with straightforward steps to get them up and running on the technology and how to use it.
One thing your parents will need for their visit is a reliable device that they’re comfortable using. It could be a computer or laptop, or it may be a smartphone or tablet. Note that in some cases their healthcare provider may use a telemedicine solution that has certain requirements as well, so you’ll want to see what those are and ensure that the device mom or dad has is compatible. (For example, the care provider may have an app that’s available through the Apple App Store or Google Play. Others may have an online platform that can be accessed by several different kinds of devices.)
If they’re using a smartphone or tablet, that will likely make things easier because the camera and microphone are already integrated into the device—all set up and ready to go. For a computer or laptop, you can help them get familiar with the setup, like the microphone levels, speaker volume, and camera. For audio, you can see a set of headphones or smartphone earbuds work well for them, which can help prevent audio feedback loops and simply make it easier to hear the caregiver.
If you’re looking for a little assistance with a Windows computer, you can check out this quick article for setting up the audio and this article for setting up the camera. For Macs, check out this article for audio and this article for the video.
If they don’t already have comprehensive online protection software for their devices, look into getting it. This will protect them against malware, viruses, and phishing attacks. They’ll also benefit from other features that help them manage their passwords, protect their identity, safeguard their privacy, and more.
As for privacy in general, medical information is among the most precious information any of us have. For example, here in the U.S., we have HIPPA privacy standards to protect our medical records and conversations. Yet there’s also the issue of eavesdropping, which is a risk in practically any online communication.
To help address privacy issues and concerns, health care providers will often post a set of Frequently Asked Questions (FAQ) as part of their telemedicine service. Within that, you’ll very likely find a section on personal privacy and the technologies in place to protect it. Here’s a good example of a telemedicine FAQ from the University of Washington Medicine and another example from the telemedicine page that Virginia Mason/Franciscan Health designed for its patients.
In all, if your parents have concerns about their privacy, you can absolutely assure them that it’s a valid concern. Consult the provider’s FAQ for guidance. If either of you has further questions, feel free to call the healthcare provider and speak with them.
In addition to digital security, there’s the possibility of physical eavesdropping, somebody actually listening in on their conversation from another room, apartment, or from the street. Help your older loved ones pick a place in their home where they can have some privacy and where they can’t be overheard by neighbors and passers-by. A bedroom is a fine place—or any location that’s familiar and comfortable as well. When choosing a private place, a well-lit location is important as well so that the camera captures a nice and clear image.
Additionally, you can help them prep for their visit by putting together a list of things to discuss during the visit. The U.S. Department of Health and Human Services suggests writing things down:
In addition to the above, there are further measures you can help your parents or older loved one take to further secure their telemedicine visit—and their internet usage in general.
Your telemedicine visit may require setting up a new account and password. When doing so, make sure it’s with a strong, unique password. A password manager can help. Also found in comprehensive online protection software, a password manager can create and securely store strong and unique passwords for your mom and dad, giving them one less thing they need to remember and worry about.
A VPN, or virtual private network, offers a strong layer of additional protection when you’re transmitting health data or simply having a private conversation about your health with a professional. A VPN creates an encrypted tunnel to keep you and your activity anonymous. In effect, your data is scrambled and hidden to anyone outside your VPN tunnel, thus making your private information difficult to collect. Check with the care provider to see if their telemedicine solution uses a VPN. If not, you can always get a VPN as part of your online protection software.
Beyond their devices, securing their internet router is an important step in making a telemedicine visit safe and secure. The data that travels along it is of a highly personal nature already, so make sure the router has a strong and unique password. Also, change the name of their router so it doesn’t give away their address or any other signs of their identity. One more step is to check that your router is using an encryption method, like WPA2, which will keep your signal secure. If you have questions, check with their internet provider—they may even offer up a newer, more secure router to replace an older one.
As with anything concerning their health, have your parents and loved ones consult with their caregivers to ensure that a telemedicine visit is a proper course for them.
So while the technical ins and outs of preparing for a telemedicine visit may have their challenges for some older adults, we should also realize that getting comfortable with the idea of a telemedicine visit in the first place may take some time and effort. Starting with regular video chats with the family may increase familiarity and ease with holding a conversation over video. Likewise, having a conversation with their doctor about telemedicine may put some concerns to rest as well. After all, they will have a relationship with their doctor. Getting the facts from the doctor, face to face may help.
We all want what’s best, particularly when it comes to the care of our parents and older loved ones in our lives, and choosing to try telemedicine is a highly personal decision for them. I hope this article and the resources cited within it will help you enable them to make the choice that’s comfortable, effective, and right for them.

Have you ever been online and replied to a comment or post? Maybe it was on Reddit or on an influencer’s Instagram. Did other people reply to you, and were any of them unexpectedly hostile? When you’re online, a little hostility is sadly par for the course, but most people brush it off and move on to enjoy other aspects of life online. But what would you do if that unpleasant interaction went much farther than was reasonable? What if one day you discovered the most important parts of your identity had been maliciously and intentionally revealed online? Let’s talk about doxxing – what it is and how you can avoid becoming a victim of this kind of harassment.
Doxxing, derived from the hacker term “dropping docs”, is internet slang for revealing someone’s identity online for the purposes of harassing them. It usually goes way beyond simply revealing someone’s email address or name and may involve personal information like a home address or workplace, SSN, financial information, phone number, pictures, texts, IP address, and other important details. The tricky thing about doxxing is that aspects of it may not be a crime, depending on what you’ve made publicly available online. However, the context in which doxxing occurs is crucial. Often it’s the first step taken to incite more severe harassment. For instance, the doxxer may not plan on taking action against their target but instead hope that someone else does. When put up against a recent Pew Research report showing that 41% of U.S. web users experience harassment in some form, it’s clear that Doxxing is a dangerous trend online.
Doxxing is a problem that’s grown in scope simply because there’s so much more data about us being kept online. Third-party services, called data brokers, capture our account info, the sites we visit, how long we spent on them, and other kinds of metadata to create profiles they then resell to advertisers. If someone gets access to these troves of data, they can reveal extremely damaging information about an individual, or data that allows a person to be damaged. For instance, with a phone number and a current address, some criminals were able to call in SWAT teams on innocent individuals. Political dissidents are often doxxed by the governments their protesting against. And on a lighter note, the adult website Ashley Madison, which promotes extramarital affairs, had their members’ data leaked online, to the embarrassment of a few public figures.
The response should be very similar to the one you’d take if your wallet was stolen. Move fast, stem the loss, and begin remediation as soon as possible. Here are some broad steps that can be taken.
Of course, not being doxxed in the first place is the ultimate goal of a proactive online protection plan. Here’s what we recommend:
Identity theft protection services help protect your data, monitor your online accounts like emails, SSNs, and more. In addition to online monitoring, they should also offer insurance and even theft remediation if the worst should occur.
Before you tag your location, friends, or workplace in a photo think about who has access to this information. What’s gained or lost by sharing all that info? Also, security questions for your accounts should not use the name of your pet or your first-born child if you have posted those on Facebook.
Public Wi-Fi networks at coffee shops and airports may not be secure against hackers and snooping. That’s why we recommend using a VPN whenever you’re connected online. This powerful tool hides your activity and location whenever you’re online on an unsecured network.
Googling yourself is a great way to see if anyone is using your online identity in bad ways.
Social networks allow you to control who can see your data. Usually, with a few clicks, you can restrict what you show online to a great degree. For instance, makes your payments viewable to other users as a default, but can easily be changed to hide them from the public.
Using long, complex, unique passwords for every account is convenient and maybe the best way to prevent your information from being stolen. Yes, we said convenient because with a password manager you only need to remember one key to create and manage much longer ones for all your most important accounts.
The reality is that the more we live online, the more our identities will too. This does not mean we need to live a restricted life online. In fact, using comprehensive online protection, which features most of the tools above, we can remain free to enjoy life on our terms. Doxxing is something to be aware of, but with great protection, it’s far from anything we need to be worried about as we make the most of our lives online.
The post Doxxing, The Internet, and How You Can Lock Down Your Data appeared first on McAfee Blog.
The internet has opened up wonderful new possibilities in our world, making life easier on many levels. You can pay your bills, schedule your next family vacation, and order groceries with the click of a button. While the internet offers many positive benefits, it also has some negatives. Although not entirely used for illicit purposes, the dark web is one part of the internet that can be used by criminals for illegal purposes, like selling stolen personal information.
But just what is the dark web? Basically, it’s a part of the internet that isn’t indexed by search engines. As an average internet user, you won’t come across the dark web since you need a special browser to access it. It’s certainly not something you need to stress about in your day-to-day browsing, and you shouldn’t let it scare you off the internet. Unless you actively seek it out, you’ll likely never have any contact with the dark web in your lifetime.
A better understanding of what the dark web is and the possible threats it contains can help you protect yourself, though. This guide provides the essential information you need, explaining the different levels of the web and revealing how you can stay safe. With this knowledge, you can continue to browse online with confidence. Find out more below.
The “dark web” refers to websites that aren’t indexed by search engines like Google and Bing. This might seem strange since most people want their websites to be found through specific searches. Practices like search engine optimization (SEO) are specifically implemented to help websites perform well and rank higher in search engine results.
So, why would someone not want their website to be picked up by a search engine? The primary purpose is to preserve privacy and anonymity. The individuals and organizations on the dark web often engage in illegal activities and want to keep their identities hidden — something that is difficult to do with an indexed website.
It’s important to note that the dark web should not be confused with the deep web, which is a part of the internet individuals access regularly. Although the terms are sometimes used interchangeably, they actually refer to different things. Deep web content — which isn’t picked up by search engines, either — includes pages that typically require additional credentials to access. Your online banking accounts and email accounts, for instance, are examples of deep web content.
The internet is home to billions of websites — an estimated 1.7 billion to be exact, although that number changes every day as new sites are made and others are deleted. Your daily internet activity likely falls within the publicly available and readily accessible portion of the internet (otherwise known as the surface web). However, there are additional “levels” of the internet beyond that top level. Read on to learn more.
The internet you use to search for more information is referred to as the surface web or open web. This is the readily visible part of the internet anyone can access with an internet connection and a normal web browser like Safari, Mozilla Firefox, or Google Chrome. Other terms for the surface web include the visible web, lightnet, or indexed web.
Examples of content you’ll find on the surface web include:
Basically, the sites you use daily — from your favorite news site to a local restaurant — are part of the surface web. What makes these websites part of the surface web is that they can be located via search queries and have recognizable endings like .com, .edu, .gov, or .org. You are able to find websites on the surface web because they are marked as “indexable,” meaning search engines can index and rank them. The sites are readily available on the search engine results pages (SERPs).
Interestingly, the surface web only makes up around 4% of the total internet, meaning the internet is a lot more than what you see on the surface. Think of it as an ocean — there’s the top layer of water you can see and then there’s the vast world beneath. The remainder of the internet is what’s below the surface.
The deep web refers to any page on the internet that isn’t indexed by search engines as described above. The deep web is the first level beneath the “surface” of the visible web — and it’s significantly larger than the surface web, accounting for an estimated 96% to 99% of the entire internet.
It’s important to note that just because this type of content isn’t on the surface doesn’t mean it’s nefarious or has ill intent. A lot of the time, this content isn’t indexed because it includes pages that are meant to be hidden to protect consumer privacy, such as those that require login credentials.
Here are some examples of content on the deep web:
Essentially, any webpage that requires a login is part of the deep web. That said, deep web content doesn’t necessarily have to fall into any of these categories. Any page that is non-indexable is technically also considered part of the deep web. It doesn’t have to require a login or contain sensitive data. Website creators and managers can mark pages as non-indexable if desired.
It’s worth noting that sometimes a single organization’s website will include elements of both the surface web and the deep web. Take a college or university website, for example. Most schools have a comprehensive website providing information about the school’s history, campus location, student body, available programs of study, extracurricular activities, and more.
However, many schools also have an intranet — sometimes linked from the main university page — that’s accessible only for students or staff. This is where students might sign up for classes and access their school email, for example. Since this is sensitive information and requires a unique login, it doesn’t need to be made publicly available via search engines.
In fact, it’s better in the interest of privacy that these pages aren’t readily visible. It helps to protect the user’s data. From this example, you can see that the “deep web” doesn’t have to be scary, illicit, or illegal. It serves a legitimate and useful purpose. You shouldn’t be afraid of the deep web. It’s further important to distinguish the deep web from the dark web — as the next section explains.
As mentioned, the deep web and the dark web sometimes get confused. However, they are distinct. Technically, the dark web is a niche or subsection within the deep web. It consists of websites that aren’t indexable and can’t be readily found online via web search engines. However, the dark web is a carefully concealed portion of the deep web that people go out of their way to keep hidden.
What makes the dark web distinct from the broader deep web is the fact that dark web content can only be accessed via a special browser. The Tor network is often used to access the dark web.
Additionally, the dark web has a unique registry operator and uses security tools like encryption and firewalls, further making it inaccessible via traditional web browsers. Plus, the dark web relies on randomized network infrastructure, creating virtual traffic tunnels. All of these technical details serve to promote anonymity and protect dark web users’ privacy.
The short answer is no, it’s not illegal to browse the dark web. In fact, there are instances where individuals can use it for good. Whistleblowers, for instance, can find the anonymity available through the dark web valuable when working with the FBI or another law enforcement organization.
That said, while it’s not illegal to browse the dark web, it’s also not completely void of criminal activity. Putting yourself in close proximity with illegal activities is rarely a good idea and could heighten your risk of being targeted by a criminal yourself. It’s often best to leave that part of the deep web alone.
There are also many technological threats on the dark web. Malicious software, also known as malware, is a critical concern and can affect unsuspecting users. Even simply browsing the dark web out of curiosity can expose you to such threats, like phishing malware or keyloggers. While an endpoint security program can identify such threats if they end up on your computer, it’s ideal to avoid them altogether.
Further, if you try to buy something on the dark web — even if it’s not illegal — there’s a chance you’ll be scammed. Dark web criminals use a variety of tricks to con people. For example, they may hold money in escrow but then shut down the e-commerce website and take off with the money. Due to the anonymous nature of the dark web, it’s very difficult for law enforcement to find such perpetrators.
Given its anonymous nature, the dark web clearly has an obvious appeal for cybercriminals. But just what do they use it for? The most obvious type of internet activity is the buying and selling of black market goods and services, from illegal drugs to illegal content. Cybercriminals may also run scams when selling such items, for example by taking a person’s money and not delivering the required product.
There are dark websites dedicated to the purchase and sale of illegal products or services (usually using untraceable cryptocurrencies like bitcoin) including:
Browsers like Tor, an open-source and free software, allow people to access dark websites where these goods are available, like a digital marketplace. These websites may look similar to any other surface or deep website you’d encounter. However, they differ in their domain suffix, ending in “.onion” instead of more obvious options like “.com” (Tor is actually short for The Onion Router, which is also where the term “onion routing” comes from — referring to anonymous communication on the dark web).
Onion sites often use scrambled names that make their URLs difficult to remember, minimizing the odds of being reported to authorities. It’s possible to search the dark web using specialized dark web search engines like Grams or link lists like The Hidden Wiki. However, these sources tend to be slow and unreliable, just like the dark web itself.
Some of this information can be extremely valuable on darknet forums. For example, while a Social Security number might go for $2, email credentials could sell for as much as $120,000. Hackers can make a lot of money and do so with less worry that they might get caught. Thanks to the Tor browser’s layers of encryption and IP scrambling, it’s difficult to track people down on this part of the web.
Again, although the dark web isn’t inherently bad, you should still be proactive in preventing your personal information from falling into the wrong hands. Here are a few ways you can help keep you and your family safe online:
The dark web might sound scary. The fact is, an everyday internet user like yourself likely won’t have any contact with this level of the internet. That said, it’s still important to take as many precautions as you can to keep your family and your technology safe.

In February 2021, the company Dbappsecurity discovered a sample in the wild that exploited a zero-day vulnerability on Windows 10 x64.
The vulnerability, CVE-2021-1732, is a win32k window object type confusion leading to an OOB (out-of-bounds) write which can be used to create arbitrary memory read and write capabilities within the Windows kernel (local Elevation of Privilege (EoP)). Memory exploitation generally requires a read, write, and execute primitive to bypass modern exploit mitigations such as DEP, ASLR and CFG on hardened operating systems such as Windows 10. A data-only attack requires only a read and write primitive as it does not seek to execute malicious code in memory, but rather manipulates data structures used by the operating system to its advantage (i.e., to achieve elevated privileges).
Kernel exploits are usually the most sophisticated attack as they interact directly with the Windows kernel. When such attacks are successful, they are critical because they provide high privileges to the attacker, which can be used to increase the impact of the overall exploit chain. In this case the exploit is a Local Privilege Escalation (LPE) that targets 64-bit Windows 10 version 1909. The original sample discovered was compiled in May 2020 and reported to Microsoft in December 2020. While searching for additional findings we went through a public exploit published in March of 2021 by a researcher. Having this code publicly available may raise the potential for additional threat attackers. While we have not found clear evidence demonstrating malicious use of the proof-of-concept (POC), we did discover some variants being tested and uploaded to VirusTotal.
In this blog post, McAfee Advanced Threat Research (ATR) performed a deep dive into the analysis of the vulnerability, to identify the primitives for detection and protection. The exploit is novel in its use of a new win32k arbitrary kernel memory read primitive using the GetMenuBarInfo API, which to the best of our knowledge had not been previously known publicly.
Exploitation of CVE-2021-1732 can be divided into six stages with the end goal of escalating a process’ privileges to System. The following diagram shows the stages.
Before we dive into the details, we must give some background to win32k exploitation primitives which are used in the exploitation of CVE-2021-1732.
Win32k is a Graphical (GUI) component of the Microsoft Windows Subsystem, most of which exists in the kernel for performance reasons. It is used for graphical print of the Windows OS desktop. However, due to the win32k architecture, the kernel component of win32k still needs to be able to make calls to user mode through user-mode callback functions to facilitate window creation and management.
Kernel user-mode callbacks have been well researched as far back as 2008 and 2010, with a very comprehensive analysis in 2011 by Mandt. A win32k kernel function such as xxxCreateWindowEx will make a callback function such as xxxClientAllocWindowClassExtraBytes through the user process PEB KernelCallbackTable.
When the user-mode callback has completed, NtCallbackReturn executes and passes the expected return parameter back to the kernel. Due to the stateless nature of these callbacks, many vulnerabilities have been discovered related to the locking mechanisms on the objects leading to use-after-free (UAF) exploitation.
Win32k has been one of the most exploited components in the Windows kernel accounting for 63% of vulnerabilities from 2010 to 2018, due to its large attack surface of syscalls relative to ntdll syscalls. Win32k vulnerabilities are generally turned into data-only attacks using a read/write kernel primitive by using a desktop object known as a tagWND data structure.
There are two aspects to data-only attacks:
The tagWND data structure has two fields which make it a prime target for reading/writing within kernel memory; tagWND.cbWndExtra and tagWND.ExtraBytes. When a window is created using CreateWindowEx, it is possible to request additional bytes of memory directly after the tagWND object in memory through the cbWndExtra field in the WNDCLASSEXA structure when registering the window class.
The number of extra bytes is controlled by the cbWndExtra field, and the allocated additional memory address is located at the ExtraBytes field. The read/write primitive is created as follows:
Win32k kernel user-mode callbacks have been exploited many times by leveraging tagWND read/write capabilities within the Windows kernel for escalation of privileges such as CVE-2014-4113, CVE-2015-0057, MS15-061, CVE-2016-7255 and CVE-2019-0808.
Several primitives have been observed in the CVE-2021-1732 exploit used by the attackers; additionally, it is worth mentioning that some of them are new and not previously seen in the wild.
Prior to Windows RS4 it was trivial to leak tagWND kernel addresses using multiple techniques, such as calling HMValidateHandle to copy tagWND objects from the kernel to user desktop heap. The latest version of Windows 10 has been hardened against such trivial techniques.
However, using the spmenu kernel address leak technique and relative tagWND desktop heap offsets, once a vulnerability is discovered to overwrite a tagWND.cbWndExtra field, it is possible to achieve kernel read/write capabilities without leaking the actual tagWND kernel addresses. The spmenu technique in this exploit was used here and here, but we are not aware of the GetMenuBarInfo API ever being used before in a win32k exploit.
The following diagram shows the primitives used in CVE-2021-1732.
Great work has been done to harden the security of win32k against EoP attacks with new and improved mitigations by the Microsoft OSR team, Mandt, Google Project Zero, Schenk and Dabah. These mitigations include:
In the context of a malicious process exploiting CVE-2021-1732, the above mitigations provide no protection. However, it does not impact Google Chrome as it disallows win32k calls (Windows 8 and higher), or Microsoft Edge as it applies win32k filtering on the relevant APIs.
When a window is created using CreateWindowEx API, a tagWND object is created by the Windows operating system. This window, as explained above, can be created with a parameter to allocate extra memory using cbWndExtra.
During the windows creation process (CreateWindowEx API) a callback named xxxClientAllocWindowClassExtraBytes is triggered to allocate space in the user mode desktop heap for the tagWND.ExtraBytes (offset 0x128) per the tagWND.cbWndExtra (offset 0xc8) value size (see figure 3 and 4 below for WND1).
The location of this memory is stored as a user mode memory pointer to the desktop heap and placed at tagWND.ExtraBytes. It is then possible to convert the normal window to a console window using NtUserConsoleControl which will convert that user mode pointer at tagWND.ExtraBytes to an offset value which points into the kernel desktop heap (see figure 5 below for WND0). It is this change in value at tagWND.ExtraBytes (window type confusion) that can be exploited for an OOB write during the xxxClientAllocWindowClassExtraBytes callback window.
Per figure 6 above the following steps are required to trigger the vulnerability:
5. WND0 is then converted to a console window by calling NtUserConsoleControl which converts WND0.ExtraBytes from a user desktop heap pointer to an offset within the kernel desktop heap. This is needed later so that WND0 can write OOB to WND1.
6. Create malicious window WND_Malicious using the CreateWindowEx API
The vulnerability lies in the fact that win32kfull!xxxCreateWindowEx does not check whether the window type has changed between the time it initiates the xxxClientAllocWindowClassExtraBytes and gets the response from NtCallbackReturn.
When we call NtUserConsoleControl with WND_Malicious in the hook above, xxxConsoleControl checks if tagWND+0xE8 flag has been set to 0x800 to indicate a console window per figure below. As WND_Malicious was created as a normal window, xxxConsoleControl allocates memory at an offset within the kernel desktop heap and then frees the user desktop heap pointer existing at WND_Malicious.ExtraBytes (0ffset 0x128). It then places the offset to this new allocation in the kernel heap at WND_Malicious.ExtraBytes (0ffset 0x128) and sets the tagWND+0xE8 flag to 0x800 to indicate it’s a console window.
After returning from the callback when we issued NtCallbackReturn above, xxxCreateWindowEx does not check that the window type has changed and places the WND0+0x08 at WND_Malicious.ExtraBytes per figure 9 below. The RedirectFieldpExtraBytes checks the WND_Malicious.ExtraBytes initialized value but it is too late as WND0+0x08 has already been written to WND_Malicious.ExtraBytes (offset 0x128).
The patched win32kfull.sys has updated xxxCreateWindowEx to now check the ExtraBytes initialized value before writing the returned value from user mode to tagWND. ExtraBytes (offset 0x128) per figure 10 below.
Figure 11 below shows that tagWND. ExtraBytes is initialized to zero within xxxCreateWindowEx during normal window creation.
Figure 12 below shows that tagWND. ExtraBytes is initialized to the new offset value in the kernel desktop heap within xxxConsoleControl during console window creation. RedirectFieldpExtraBytes simply checks this initialized value to determine if the window type has changed. In addition, Microsoft have also added telemetry for detecting changes to the window type flag in the patched version.
The vulnerability within the xxxCreateWindowEx API allowed the WND_Malicious.ExtraBytes field be to set to a value of WND0 offset within the kernel desktop heap. Now any time SetWindowLongW is called on WND_Malicious it will write to WND0. By supplying an offset of 0xc8, the function will overwrite the WND0.cbWndExtra field to a large value of 0XFFFFFFF per figures 13 and 14 below.
This means it can write beyond its tagWND structure and ExtraBytes in kernel memory to fields within WND1. In addition, WND0.ExtraBytes is also overwritten with the offset to itself so calls to SetWindowLongPtrA on WND0 will write to an offset in kernel desktop heap relative to the start of WND0.
Now that the WND0.cbWndExtra field has been set to a very large value (0xFFFFFFF), anytime SetWindowLongPtrA is called on WND0 it will write into the adjacent WND1 in kernel memory per figure 15 below. By writing to specific fields in WND1 we can create a kernel address memory leak as follows:
Using the spmenu data structure kernel pointer leaked previously we can use the layout of this data structure and the GetMenuBarInfo API logic to turn it into an arbitrary kernel memory read per figures 18,19 and 20 below.
As you can see from the xxxGetMenuBarInfo function in figures 21 and 22 below, by placing our leaked kernel address at the right location in our fake spmenu data structure we can create an arbitrary kernel memory read when calling GetMenuBarInfo.
An arbitrary kernel write primitive can be easily achieved now by writing our destination address to WND1.ExtraBytes field by calling SetWindowLongPtrA on WND0 which will write OOB to WND1 relative to the offset we specify per figure 23 below
In this case the offset is 0x128 which is ExtraBytes. Then simply calling SetWindowLongPtrA on WND1 will write a specified value at the address placed in the WND1.ExtraBytes field. The arbitrary write is achieved because WND1 is a normal window (has not been converted to a console window like WND0 and WND_Malicious) and so will write to whatever address we place in WND1.ExtraBytes.
The arbitrary kernel read and write primitives can be combined to perform a data-only attack to overwrite a malicious process EPROCESS token with that of PID 4 which is System for an escalation of privilege (EoP).
The original spmenu kernel address leaked previously has a pointer to WND1 at offset 0x50 per figures 24 and 25 below. Through multiple arbitrary reads using the GetMenuBarInfo on our fake spmenu data structure with this WND1 kernel address we can eventually read the PID 4 System EPROCESS token.
By placing the destination address (malicious process EPROCESS token) at WND1.ExtraBytes then the subsequent call to SetWindowLongPtrA will write the value (PID 4 – System EPROCESS token) to that address per figures 26 and 27 below.
The exploit then restores overwritten data structure values once the EoP is complete to prevent a BSOD (Blue Screen of Death).
In this report, we undertook a deep analysis of CVE-2021-1732 which is a Local Privilege Escalation on Windows 10. Windows kernel data-only attacks are difficult to defend against, as once a vulnerability is discovered they use legitimate and trusted code through specific APIs to manipulate data structures in kernel memory.
The win32k component has been hardened through great work by Microsoft against read/write primitives, but there are still opportunities for exploitation due to its large attack surface (syscalls and callbacks) and lack of win32k filtering on a process-wide basis. It would also be great to see a system wide win32k filtering policy capability within Windows 10.
Patching is always the best solution for vulnerabilities, but a strong defense strategy such as threat hunting is also required where patching may not be possible, and to detect variants of vulnerabilities/exploits being used by campaigns.

If you’re reading these words, CONGRATULATIONS! You’ve made it to 2022! And even better, you found your way to ATR’s monthly security digest where we discuss our favorite vulnerabilities of the last 30 days. Feel free to pat yourself on the back, get yourself a nice cup of coffee, tea, LaCroix (you fancy!) or if you’d rather choose violence, you can go straight for the energy drink. And now that we are comfortable and energized, let’s get rolling!
Per its Wikipedia entry, Grafana is a multi-platform open-source analytics and interactive visualization web application that is widely used in the industry, with paying customers such as Bloomberg, eBay, PayPal, etc. It was revealed in early December that a path traversal vulnerability allowed an attacker to access local files due to an improper sanitization of “../../../” in its plugin path.
It also showcases one of the tightest disclosure timelines known to man:
Ok, we can hardly blame you for hearing about ANY vulnerabilities except for Log4Shell in the last 30 days. However, if your organization is using this software, you probably should have followed the disclosure last month, lest your “/etc/passwd” files are now known to the whole internet. Beyond that, there are two interesting points you can ponder while swirling your eggnog in its glass (side-rant on the disgustingness of eggnog redacted). Given how easy it is to exploit, the mere fact of the vendor fixing the bug via their public GitHub seems to have been enough to bring attention to it and get public working POCs for this vulnerability in less than 3 days following the fix. If you’re curious about how more mature open-source code bases deal with this risk, projects like Chromium rely on a separate bug tracking infrastructure that can restrict who can access the bug reports (that will spell out the security risks and test cases) combined with public commit messages with simple phrasing meant to avoid attracting the attention on the security commits.
Another interesting tidbit, the root cause of this bug is the misuse of a Go API to sanitize paths as discussed in this Twitter thread. It turns out the filepath.Clean function used to sanitize the input processed by the vulnerable code only removes excessive “../../” if the path is absolute. This is a common case of an API behaving as expected but leading to dangerous consequences. Do you know for sure the codebase of your organization is free of these problems? The impact of unpatched vulnerabilities here could be the accessing or leaking of extremely sensitive data. *pondering becomes frantic*
Obviously update the software if you’re using it, and you can also use Sigma rules to detect attack attempts. In an ideal world, your analytics platform should not be exposed to the wide internet, unlike these 87k instances, among whose 16k are still vulnerable according to Shodan. At minimum make sure your Grafana instance is behind a .htaccess prompt or similar. From a development perspective, security testing and unit tests should be leveraged to ensure the filtering you are putting in place is working the way it is intended to. And in the grand scheme of things, if you are going to process untrusted user input, don’t wing the filtering and apply thoroughly audited code patterns rather than disabling the warnings of your security tool…
“Does the walker choose the path, or the path the walker?” may have mused Garth Nix in his novel Sabriel. One thing is certain though, the path described above won’t be “walked” nor traversed by an attacker for the McAfee Network Security Platform (NSP) customers. These lucky fellows are already protected against path traversal attacks via a generic rule and can even be bestowed further protection with the creation of “custom attack” rules.
Who could have known that parsing—and sometimes even executing—untrusted input was a bad idea? Well it turns out that Apache’s log4j logging code does exactly that, and if the logged string contains the magic characters $(jdni:…) it may even fetch and execute untrusted Java code. Iterations on this attack have also highlighted the possibility to leak local secrets stored in environment variables—such as AWS keys—and given the recursiveness of the processing, it also offers many ways to evade pattern-matching detection.
Pretty much everyone. You write Java and are into logging things? Yep, you should be on top of this. You use Java based applications/servlets? Well, there’s probably some logging of untrusted user input in there. Your corporate employer uses Java based appliances or services? Pour one for your SOC and IT folks who are probably having a blast over their holiday “break”. You get it, this problem impacts the whole industry, and in all likelihood, its effects will probably keep rippling out for the years to come. To make things worse, the bug is really easy to exploit. From pen testers to SOC analysts, “script-kiddies” to nation state actors, nearly everyone has begun to explore this attack vector and we have observed massive on-going attacks with a wide gamut of payloads, ranging from cryptominers to “rm -rf /*” payloads and even a broken attempt to spread the Mirai worm. The worst is likely yet to come.
“Stranger Things” taught us that “You can’t spell America without Erica.” Similarly, you can’t spell Apache without Patch. Sort of. Upgrade! Micro-patch. Monitor traffic. Hint: if you’re internal-only application suddenly makes LDAP requests towards a remote server in a country you have no operations in, maybe something fishy is going on…
If you like chaos and and/or you are having a hard time convincing IT of the importance of this bug, get permission to demonstrate it for them! Then, set strings you can control (user-agent, twitter name, wifi SSID, …) to this $(jdni:ldap…) magic value and make it point to an IP:Port you control (or a third party service like Canarytoken if you trust them). If you detect hits on that address, you can start having a fun conversation about the necessity of upgrading their tech stack with the owners of the incoming addresses. This is where asking for permission first becomes extremely important, as if you indiscriminately put the magic string all over the places to see what happens (as you may have seen on various social media platforms), it’s likely that eventually someone will reach out to have a “fun” conversation with you and ask about that funky user-agent of yours. Obviously, before pulling a stunt like this consider that the last thing you want for Christmas is a CFAA (Computer Fraud and Abuse Act) complaint delivered right to your doorstep.
McAfee Enterprise customers are protected from many different angles (for the specifics, please visit this Knowledge Base article):
Big Sig sounds like the nickname Freud’s mother gave him. This bug is no less compelling. Early this December, Google Project Zero blogged about a vulnerability they found in Mozilla’s Network Security Services (NSS) with a CVSS score of 9.8, according to NIST’s National vulnerability database page. There is a heap overflow in the processing of certain signatures (DER-encoded DSA and RSA-PSS signatures). To put it simply, the NSS is a collection of cryptographic libraries that enable developers to use safer/heavily tested implementations of cryptographic primitives and standards (for encryption of communication, verification of the authenticity of data, and so on). The feature where the bug was found is responsible for the verification of signatures that prove the authenticity of data using various public cryptography schemes. This type of function is typically used to sign emails or documents to confirm their actual authors. Something really interesting about this bug is its relative simplicity but also its long existence; according to Project Zero’s blog, this bug was exploitable going all the back to 2012. The vulnerable code path just happened to fall between the cracks where various fuzzers used by Mozilla overlap.
If you like your signatures to be verified, and rely on the NSS library to do so, you should definitely have a look at the advisory and use the latest version of the software (NSS version 3.73/3.681 ESR or later). Firefox seems unaffected, but other software that parses signatures might be impacted (Thunderbird, LibreOffice, Evolution, Evince and more).
As usual, you want to make sure any software you are using that might be vulnerable is updated to its latest version. The patch was released on December 1st so, for starters, you’d want to make sure potential vulnerable software received an update after this date. It would also help to know which software relies on this library; while there is no magic bullet, references to files such as nss3.dll on Windows or libnss3.so on Linux are a good starting point. Beyond that, the best call is to look at release notes and potential list of third-party libraries used in any given application you may use. If you use the vulnerable library in in your own product, update the code or backport the patch.
Have you checked out our bulletins? They’re a great source of information for the critical vulnerabilities you may have missed! This may include applications that will be deploying fixes for CVE-2021-43527.

It happens with more regularity than any of us like to see. There’s either a headline in your news feed or an email from a website or service you have an account with—there’s been a data breach. So what do you do when you find out that you and your information may have been caught up in a data breach? While it can feel like things are out of your hands, there are actually several things you can do to protect yourself.
Let’s start with a look at what kind of information may be at stake and why crooks value that information so much (it’s more reasons than you may think).
The fact is that plenty of our information is out there on the internet, simply because we go about so much of our day online, whether that involves shopping, banking, getting results from our doctors, or simply hopping online to play a game once in a while.
Naturally, that means the data in any given breach will vary from service to service and platform to platform involved. Certainly, a gaming service will certainly have different information about you than your insurance company. Yet broadly speaking, there’s a broad range of information about you stored in various places, which could include:
As to what gets exposed and when you might find out about it, that can vary greatly as well. One industry research report found that 60% of breaches were discovered in just days from the initial attack while others could take months or even longer to detect. Needless to say, the timeline can get rather stretched before word reaches you, which is a good reason to change your passwords regularly should any of them get swept up in a breach. (An outdated password does a hacker no good—more on that in a bit.)
The answer is plenty. In all, personal information like that listed above has a dollar value to it. In a way, your data and information are a kind of currency because they’re tied to everything from your bank accounts, investments, insurance payments—even tax returns and personal identification like driver’s licenses.
With this information in hand, a crook can commit several types of identity crime—ranging from fraud to theft. In the case of fraud, that could include running up a bill on one of your credits cards or draining one of your bank accounts. In the case of theft, that could see crooks impersonate you so they can open new accounts or services in your name. Beyond that, they may attempt to claim your tax refund or potentially get ID issued in your name as well.
Another possibility is that a hacker will simply sell that information on the dark marketplace, perhaps in large clumps or as individual pieces of information that go for a few dollars each. However it gets sold, these dark-market practices allow other fraudsters and thieves to take advantage of your identity for financial or other gains.
Most breaches are financially motivated, with some researchers saying nearly 90% of breaches are about the money. However, we’ve also seen hackers simply dump stolen information out there for practically anyone to see. The motivations behind them vary, yet could involve anything from damaging the reputation of an organization to cases of revenge.
A list of big data breaches is a blog article of its own, yet here’s a quick list of some of the largest and most impactful breaches we’ve seen in recent years:
Needless to say, it’s not just the big companies that get hit. Healthcare facilities have seen their data breached, along with the operations of popular restaurants. Small businesses find themselves in the crosshairs as well, with one report stating that 43% of data leaks target small businesses. Those may come by way of an attack on where those businesses store their records, a disgruntled employee, or by way of a compromised point-of-sale terminal in their store, office, or location.
In short, when it comes to data breaches, practically any business is a potential target because practically every business is online in some form or fashion. Even if it’s by way of a simple point-of-sale machine.
When a business, service, or organization falls victim to a breach, it doesn’t always mean that you’re automatically a victim too. Your information may not have been caught up in it. However, it’s best to act as if it was. With that, we strongly suggest you take these immediate steps.
Given the possibility that your password may be in the hands of a hacker, change it right away. Strong, unique passwords offer one of your best defenses against hackers. Update them regularly as well. As mentioned above, this can protect you in the event a breach occurs and you don’t find out about it until well after it’s happened. You can spare yourself the upkeep that involves a password manager that can keep on top of it all for you. If your account offers two-factor authentication as part of the login process, make use of it as it adds another layer of security that makes hacking tougher.
If you spot unusual or unfamiliar charges or transactions in your account, bank, or debit card statements, follow up immediately. That could indicate improper use. In general, banks, credit card companies, and many businesses have countermeasures to deal with fraud, along with customer support teams that can help you file a claim if needed.
If you haven’t done so already, consider signing up for a service that can monitor dozens of types of personal information and then alert you if any of them are possibly being misused. Identity protection such as ours gives you the added benefit of a professional recovery specialist who can assist with restoring your affairs in the wake of fraud or theft, plus up to $1 million in insurance coverage.
Our advice is to take a deep breath and get to work. By acting quickly, you can potentially minimize and even prevent any damage that’s done. With that, we have two articles that can help guide the way if you think you’re the victim of identity theft, each featuring a series of straightforward steps you can take to set matters right:
Again, if you have any concerns. Take action. The first steps take only minutes. Even if the result is that you find out all’s well, you’ll have that assurance and you’ll have it rather quickly.

Log4j/Log4shell is a remote code execution vulnerability (RCE) in Apache software allowing attackers unauthenticated access into the remote system. It is found in a heavily utilized java open-source logging framework known as log4j. The framework is widely used across millions of enterprise applications and therefore a lucrative target for threat actors to exploit. The availability of the POC exploit and ease of exploitation triggered the widespread exploitation attempts that we are now witnessing.
CVE-2021-44228 – Apache Releases Log4j Version 2.15.0 to Address Critical RCE Vulnerability Under Exploitation.
Should the vulnerability be present, an attacker might run arbitrary code by forcing the application or server to log a specific string. This string can force the vulnerable system to download and run a malicious script from the attacker-controlled system, which would allow them to effectively take over the vulnerable application or server.
A full technical analysis can be found here:

Organisations preparing to defend against this threat needs to think beyond the initial access vector. What the vulnerability allows a threat actor to do is initially only connect to a remote endpoint and establish a beachhead. The attacker only gets a return on investment when they can exploit that initial foothold either to move laterally, execute additional payloads on the endpoint or attack other organisations as part of a botnet. Instead of just focusing on the initial access vector, let’s look at the entire defensive kill chain.
The impact on organisations varies between resource takeover, denial of service or data theft. Therefore, making visibility in attack patterns and trend via threat intelligence extremely critical. In addition, other attack vectors have been discovered which allows for local exploitation of the log4j library over WebSocket.
Let’s walk through the defense lifecycle in more details
Threat Intelligence is critical to adapt security controls and gain an understanding of attacker techniques and active campaigns exploiting the vulnerability
The MVISION Insights platform reports threat intelligence related to the Log4j attacks under the campaign name Log4Shell – A Log4j Vulnerability – CVE-2021-44228.
The Global Prevalence map snapshots captured on the 10th and 16th December 2021 demonstrates how impactful has being the vulnerability so far and how fast activity, both defender and attack, is increasing and spreading worldwide.
MITRE Techniques Observed:
As we are writing this blog, on MVISION Insights there are 1,813 IOCs including MD5, SHA256, URL, IP, DOMAIN, HOSTNAME. In terms of Determinism, 1,632 are unique and 30 are commodity.
The top MD5 detected so far has been related to Kinsing (MD5: 648effa354b3cbaad87b45f48d59c616), a crypto miner with backdooring features. The file runs on Linux machines and has been uploaded on Virus Total for the first time in December 2020. Its detection increased by 161% between the 11th and the 15th of December 2021 and it is currently observed in 19 different countries. The log4j vulnerability is helping threat actors to push Kinsing malware via encoded payloads to vulnerable services exposed to the internet. And this is just the tip of the iceberg. We are actively monitoring for and analyzing new payloads.
The same unique indicator is also reported as part of other two threat campaign on MVISION Insights:
Since April 2020, when the Kinsing crypto miner was discovered, further developments of the malware have occurred including a rootkit component and other features that make detection harder. Kinsing comes with multiple shell scripts that download and install the backdoor, miner, and rootkit alter the system itself.
The IP address 45.155.205[.]233 included within the MVISION Insights IOCs and used by threat actor as a log4j callback attack server has been detected 6,884 times by December 4th topping 15,106 detections by December 7th. Most detected countries included the United States, Turkey, Thailand, UK, Taiwan, and Italy.
MVISION Insights also includes indicators related to unique variants of MIRAI botnet that McAfee observed being leveraged by threat actors to exploit the log4j vulnerability.
Shell scripts are using wget and curl tools for external communication as part of the attack chains analyzed.
Latest updates highlighted Conti ransomware group actively leveraging the Log4Shell exploit to gain access to internal corporate resources and lunch their malicious payloads. But also, Khonsari group and state sponsored APT35 have been reported by researchers.
In this case, you should detect and prioritise internet facing applications running java-based web servers such as Apache Tomcat, either isolate or patch these resources. Run vulnerability scans for both monolithic and containerized workloads to build an inventory of assets that might be impacted.
Continuously discovers your cloud resources and can run vulnerability scans for Virtual Machines and Containerized workloads in the cloud. MVISION Cloud has the ability to build an inventory of running processes within workloads as part of it application control capabilities. If log4j is used as a separate package we will detect the vulnerability in both runtime and container registry. If the log4j is included in the java binary we will not be able to scan it.
Ensure you run configuration audits for cloud assets that allow unrestricted outbound access and does not use firewalls or NAT GW’s for outbound connections. Run configuration audits for secondary misconfigurations that might allow the attacker to exploit IAM to elevate privileges, gain persistence or takeover other resources.
Compares the available defensive capabilities on the endpoint to the attacker techniques, tools and IOC’s and highlights exposed endpoints.
You can perform real time searches in MVISION EDR to identify endpoints with Log4j binaries.
The attacker only succeeds if they can get to this stage so blocking outbound suspicious connections, preventing execution of additional payloads, and protecting credentials/auth tokens theft are things that could prove to be critical in defeating the attack. As part of the available threat intelligence attackers are using several post exploit methodologies to pivot from the original log4j injection vulnerability. This varies from misuse of resources with crypto miners, deploying malware, or exfiltrating sensitive information.
Use Application Control (VM and Containers) to kill unverified server processes and payloads from executing.
OS Hardening (VM) – ensure that SE Linux state is enforcing
Use UCE URL filtering and Remote Browser Isolation to prevent browser-based exploit attempts over WebSocket and C2 attempts.
Use signature-based protection in ENS 10.7 to block known hashes of second stage malicious payloads. On December 12, 2021, McAfee Enterprise released V3 AMCore content 4648 (ENS) and V2 DAT 10196 (VSE). Generic detections are provided under the title Exploit-CVE-2021-44228.C.
In ENS (Endpoint Security) 10.7 update 4 and above, there is a powerful security feature available to every defender, which is the ability to trigger a memory scan from an Expert Rule. For more details on this capability, please see this blog post from our AC3 team
https://www.mcafee.com/blogs/enterprise/log4j-and-the-memory-that-knew-too-much
Additionally, it is recommended to enable the ENS ATP rules that prevent or detect post exploitation techniques such of second stage payload execution, credential dumping or encryption activity from ransomware, use of malicious tools or lateral movement.
An Emergency User Defined Signature has been written and tested by McAfee Enterprise to provide immediate protection against the Apache Log4j2 Remote Code Execution Vulnerability.
For details on latest signatures, please follow the KB…KB95091: McAfee Enterprise coverage for Apache Log4j CVE-2021-44228 Remote Code Execution
Assuming breach is critical especially if you know that you had exposed assets and therefore, build forensics and post exploitation detection techniques this includes exploitation of living of the land binaries (LOLBINS), credential dumping as well as using information such as known file hashes / hunting queries to query web server / reverse proxy/ Network IPS logs.
In addition to an Intelligence Summary, Insights provides exportable YARA rules to find additional Indicators of Compromise.
As mentioned above, you can leverage Real Time and Historical Search functionality to proactively identify vulnerable systems or post exploit activity such as…
Identify Indicators of Compromise associated with exploit payloads
Along with control on the endpoint, visibility into attacks and where data is being uploaded is also critical to stopping Data Exfiltration. Mapping threats to the MITRE ATT&CK Framework will provide visibility into ongoing attacks happening in the cloud and where security controls can be improved to stop future attacks.
Another critical method to stopping the exfiltration of data is putting restrictions against data uploads to non-sanctioned cloud storage. Limiting data uploads to only sanctioned Cloud Service Providers can stop external and insider threats from transferring data to Cloud Services that are questionable or not sanctioned. The Cloud Registry within MVISION Cloud/Unified Cloud Edge will provide ratings for well over 25,000 Cloud Service Providers so restrictions can be placed on CSPs with high risks or attributes that put company data at risk.
The current situation is dynamic and our resources to help you understand the attack and mitigations available are also evolving. For the latest updates on McAfee Enterprise threat intelligence and defender resources please continue to follow these sites

The post Threat Intelligence and Protections Update Log4Shell CVE-2021-44228 appeared first on McAfee Blog.
By Guilherme Venere, Ismael Valenzuela, Carlos Diaz, Cesar Vargas, Leandro Costantino, Juan Olle, Jose Luis Sanchez Martinez, AC3 Team
Collaborators: ATR Team (Steve Povolny, Douglas McKee, Mark Bereza), Frederick House (FireEye), Dileep Kumar Jallepalli (FireEye)
In this post we want to show how an endpoint solution with performant memory scanning capabilities can effectively detect active exploitation scenarios and complement network security capabilities your company has implemented.
As it is becoming the norm lately, a new vulnerability affecting a widely used library was recently released just in time for the Holidays. As detailed in our ATR blog, CVE-2021-44228 reported a vulnerability in the Log4J Java library affecting applications and web sites using the library to perform logging.
This vulnerability allows an attacker to coerce the vulnerable site or application to load and execute a malicious Java code from an untrusted remote location. Attack vectors are varied but the most common is associated with the attacker sending crafted strings as part of a network protocol to the target machine, like for example a modified HTTP Header sent as part of a POST request.
That is the reason many defenders are focusing their efforts on detecting the malicious strings through the network traffic. However, network signatures can be bypassed and there are reports confirming threat actors are adapting their network attacks with various forms of obfuscation to defeat network scanning. The following image shows some of the current obfuscation techniques that have been observed or reported related to this attack.
Source: https://github.com/mcb2Eexe/Log4j2-Obfucation
This doesn’t mean that network protection solutions are not useful against this attack. Network security platforms provide a first layer of defense and should be used as part of a defensible security architecture (security risk treatment strategy), augmented by additional layers of protection, detection, visibility, and response. Modern endpoint solutions are uniquely positioned to complement network-based capabilities with in-depth host-based visibility of system processes, like in-memory scanning and rapid response orchestration. This combination results in a robust defense against threats like Log4Shell.
To understand how memory scanning can help complement the network security platforms after a connection arrives to the endpoint and defeating the obfuscation layers, let’s take a look at the diagram below, describing the flow of execution for a common web based Log4J attack.
Let’s outline what happens:
In Step 1, an attacker sends a specially crafted string to the web server hosting the vulnerable application. This string, as we have seen, can be obfuscated to bypass network-based signatures.
In Step 2, the application proceeds to de-obfuscate this string to load it in memory. Once loaded into memory, the application initiates a LDAP connection to request the address of where the malicious class is located.
In Step 3, the attacker-controlled LDAP server responds with the location of the malicious Class file by indicating the HTTP URL address of where it is hosted.
In Step 4, the vulnerable application will proceed to initiate a download for that malicious class file.
In Step 5, the vulnerable application will load and run the malicious class file from step 4.
At this moment, the attacker achieves code execution on the target, leaving traces that may provide visibility on this activity for the defender. For example, spawning additional processes or touching files and registry keys after an exploitation
With this in mind, let’s imagine we could trigger a memory scan at some point in this execution flow to detect the presence of the malicious code. In general, scanning the memory of an endpoint is expensive from a processing perspective, therefore it’s not something that can be done continuously or even very often, but under specific circumstances it can be achieved with precision.
So, suppose we could trigger a memory scan at any point after step (2). We would have a high probability to find the de-obfuscated string used within the process memory at that time. If the memory is scanned after the malicious class file is downloaded, that content would also be available for scanning in its de-obfuscated form.
Such possibilities make the memory signature performant, and efficient, given the timing of the detection mainly depends on the trigger used to start the memory scan.
These technical capabilities are possible in ENS, let us show you how to do that!
In ENS (Endpoint Security) 10.7 update 4 and above, there is a powerful security feature available to every defender, and WE absolutely love it, which is the ability to trigger a memory scan from an Expert Rule.
We have talked about Expert Rules before, these are customizable access control rules which the end-user uses to detect suspicious activity not commonly seen by other scanners. McAfee Enterprise also provides community Expert Rules mapped to the MITRE ATT&CK Matrix through our public GitHub.
The feature we are interested in now is the ability to trigger a memory scan when an Expert Rule fires. That would allow us to target the applications vulnerable to Log4J and identify the moment they are being exploited.
Consider the following rule:
In the example rule above, we see a section defining ACTORS (inside the Process {…} section) and TARGETS (inside the Target {…} section). We define as actors any process that may be vulnerable to the Log4J exploit. In this case JAVA.EXE for standalone Java applications and TOMCAT?.EXE for Apache web-based applications. Either of these processes need to load both JAVA.DLL and JVM.DLL to ensure the Java runtime is active.
In the target section we add any potential payload of the attack. As Expert Rules are not focused on network traffic, we need to focus on the last step of the execution flow, which is when the payload is executed. Additional triggers like files or registry keys accessed can be added as more information about exploits become available. We may also have in this section any exclusion of valid behavior as shown in the example above with the “Exclude” on command line parameter. This exclusion is something customers can tailor to their environment to avoid false positives.
This expert rule will trigger when any ACTOR process spawns any of the TARGET payloads. If the rule were just that, one could see it would not be too effective in detecting the exploit and would probably cause many false positives.
But notice this line at the beginning of the rule:
This instruction tells ENS 10.7 to initiate a memory scan against the ACTOR process which caused the expert rule to trigger, and only that process. Now we have a reliable trigger for a performant memory scan, avoiding the performance issues of a blind memory scan, and it is done at a time very close to the initial exploitation attempt, which guarantees the de-obfuscated string will be in memory.
The second part of this solution is executed by the AV DAT Engine when it scans the memory of the process which triggered the Expert Rule. Once this string is found, a detection will occur on the affected process, and the action configured in the Expert Rule REACTION line will be applied. More information about available actions are described in KB95901 – McAfee Enterprise coverage for Apache Log4j CVE-2021-44228 Remote Code Execution. Note we recommend customers to use the REPORT action initially until they have sorted out what processes they need to monitor.
The first event highlighted above is the Expert Rule triggering for a suspicious process spawning from JAVA.EXE, and the second shows the AV DAT detection indicating the memory of that process had signatures of the exploit.
Note:
IF only the Expert Rule detection was present and NOT the JNDI/Log4J-Exploit event, it would indicate a program has executed children processes considered suspicious, and customers are advised to review the event and improve the Expert Rule accordingly.
However, IF, both the Expert Rule and JNDI/Log4j-Exploit events are triggered for the same program, we have confidently detected the presence of the process being exploited.
McAfee Enterprise provides more information about our current coverage for Log4J vulnerability in KB95901 – McAfee Enterprise coverage for Apache Log4j CVE-2021-44228 Remote Code Execution. This article contain links to download the Expert Rule and the associated EXTRA.DAT, as well as details on how to set up ePO to use them in your environment.
Customers who want to implement this solution are invited to review the instructions in the KB and associated documentation. It is highly recommended to review the Expert Rule and customize it to your environment.
To protect an environment against attacks like LOG4J, a layered strategy comprised of network security coupled by targeted endpoint memory scans allows defenders to effectively detect and prevent the attack execution flow against vulnerable systems exposed via network vectors.
Our ENS Expert Rules and Custom Scan reactions are designed to enable defenders with such capabilities so they can apply precise countermeasures against these emerging threats.

Like many consumers around the world, you’re probably scouring the internet to find the perfect gifts for your friends and family in time for the holidays. While buyers prepare for the festivities, cybercriminals look for opportunities to scam shoppers with various tricks. In 2020, the FBI received over 17,000 complaints regarding goods that were never delivered, totaling losses of more than $53 million.1 And this year, it is anticipated that the number could increase due to rumors of merchandise shortages and the ongoing pandemic.
But no need to get your tinsel in a tangle! At McAfee, we’re empowering consumers to live their digital lives with confidence by providing tips and tools for sidestepping cyber-grinches. Here are the top scams to look out for this holiday season so you can be on your merry way:
Phishing may be one of the older tricks in the book, but it is still a favorite standby for cybercriminals as phishing tactics become more sophisticated. According to Bleeping Computer, scammers tend to target holiday shoppers with emails advertising big-ticket or hard-to-find items to entice them to click on a malicious link.2 For example, cybercriminals could send a phishing email promising a sweet deal —often referred to as the discount scam — on the latest gaming system. Jumping at the opportunity to score such a great gift for a low price, an unsuspecting holiday shopper might click on the link and swiftly hand over their credit card details. But instead of receiving the gaming system, they receive alerts of suspicious purchases from their bank — purchases that cybercriminals made with their credit card information.
During the holidays, many brands increase their online advertising to boost sales. However, cyber-grinches will likely take advantage of this trend by creating fake websites and ads impersonating companies that consumers know and love. For example, cybercriminals can create fake websites and ads promoting unrealistic discounts and bargains that look remarkably similar to an online retailer’s site. If a customer clicks on the fake website and makes a “purchase” by inputting their credit card information, the scammers will then be able to use this data to make fraudulent purchases elsewhere.
Many consumers rely on social media to stay up-to-date on the latest deals, and scammers are eagerly looking for ways to take advantage. To target holiday shoppers via Instagram, Facebook, TikTok, etc., criminals use fake social media posts offering vouchers, gift cards, freebies, and contests in the hopes that the user will click on the post and hand over their personal or financial information. Perhaps a user comes across a fake contest for a $1,000 Amazon gift card on Instagram — all they have to do is enter their login credentials to enter. Little do they know that this contest has been formulated by scammers and submitting their login for entry is just handing over their data for cyber-scrooges to exploit.
Criminals can also take advantage of shoppable social media posts to target holiday shoppers with advertisements for non-existent or counterfeit items. Today, 130 million Instagram users tap on shoppable posts to learn more about products every month. It’s likely that these users will also rely on shoppable posts to interact with products they’re interested in purchasing for holiday gifts.3
Cybercriminals can entice these users by creating fraudulent social media ads for products they don’t actually have. If an unsuspecting shopper purchases through the fake ad, their financial information will not only find its way into the hands of the scammer, but they also won’t receive what they initially paid for.
According to the Wall Street Journal, travel and charity scams also tend to spike around the holidays.4 Travel scams could show up in the form of an email stating that a booking has been canceled, sending you to a fake website where you’re asked to enter your credit card number to set up a new reservation. You could also receive an email directing you to a clone site offering deals on a house rental, flight, or hotel room that seems too good to be true — as long as you hold your reservation with a deposit.
Cybercriminals also know that consumers tend to make charitable donations around the holidays, and many are quick to take advantage. A charity scam might target victims via social media feeds, asking people to donate to a fake organization. Consumers should always do their research on a charity before they donate to prevent money from ending up in a scammer’s pocket.
To prevent cyber-grinches from stealing your money, data, and festive spirit, follow these tips so you can continue to make merry during the holiday shopping season:
The post 6 Tips to Protect Yourself From Holiday Shopping Scammers appeared first on McAfee Blog.
On December 9th, a vulnerability (CVE-2021-44228) was released on Twitter along with a POC on Github for the Apache Log4J logging library. The bug was originally disclosed to Apache on November 24th by Chen Zhaojun of Alibaba Cloud Security Team. The impact of this vulnerability has the potential to be massive due to its effect on any product which has integrated the log4j library into its applications. This includes products from internet giants such as Apple iCloud, Steam, Samsung Cloud storage, but thousands of additional products and services will likely be vulnerable. This is just the beginning as Java is heavily used in applications spanning nearly every industry.
The vulnerability exists in the way the Java Naming and Directory Interface (JNDI) feature resolves variables. When a JNDI reference is being written to a log, JNDI will fetch all requirements to resolve the variable. To complete this process, it will download and execute any remote classes required. This applies to both server-side and client-side applications since the main requirements for the vulnerability are any attacker-controlled input field and this input being passed to the log.
To orchestrate this attack, an attacker can use several different JNDI lookups. The most popular lookup currently being seen in both PoCs and active exploitation is utilizing LDAP; however, other lookups such as RMI and DNS are also viable attack vectors. It’s worth noting that the simplistic LDAP/RMI attack vectors only work with older JDK versions. There are publications that have demonstrated methods to circumvent this limitation to achieve code execution, albeit with added complexity to the attack.
Java object deserialization vulnerabilities are not a new breed of vulnerabilities or attacks. Previous offensive research such as “marshalsec” can be applied to this vulnerability making code execution simplistic.
**Update 12/20/2021**
On December 18th, a new denial of service (DOS) vulnerability, CVE-2021-45105 was discovered affecting versions 2.0-alpha1 through 2.16.0 of Log4j. To mitigate the original Log4j vulnerability, Apache completely disabled JNDI lookups in version 2.16, however self-referential lookups remained a possibility under non-default configurations. When a nested variable is substituted by the StrSubstitutor class, it recursively calls the substitute() class. When this nested variable recursively references the variable being replaced, it leads to an infinite recursion and a DoS condition on the server. Current research shows this does not lead to code execution, like the previous vulnerabilities.
****
**Update 12/14/2021**
It has been confirmed that Log4j version 1.2 is vulnerable to similar attacks through the JMSAppender component and has been issued CVE-2021-4104. It is important to note this is not as easily exploitable as version 2.x. For exploitation to occur, JMSAppender must be enabled, and set with TopicBindingName or TopicConnectionFactoryBindingName configurations allowing JMSAppender to perform JNDI requests. This is not the default configuration.
****
**Update 12/20/2021**
Apache has released a new version of Log4j, version 2.17.0 to address the latest DOS vulnerability. Two additional classes were created that inherit from StrSubstitutor to deal with parsing strings that may contain user input. These additions do not allow recursive evaluation. Due to exploitation of this vulnerability leading to a DOS, it is considered less critical than the previously reported Log4j vulnerabilities which can lead to remote code execution. It is important to note, for exploitation to be successful there are several non-standard conditions that need to be met. As the Log4j situation is continuing to evolve, we recommend upgrading to version 2.17.0, where possible.
*****
**Update 12/14/2021**
Apache has released a new version of Log4j, version 2.16.0. This update disables JDNI by default requiring a user to explicitly turn the JNDI feature on and completely removes support for message lookups. When considering mitigations strategies for the Log4Shell vulnerabilities this should be considered the preferred method of mitigation.
****
There is a lot of information about different ways to mitigate this vulnerability. The most important and complete mitigation is to update log4j to the stable release version 2.17.0. Some sources are reporting that Java versions 6u211, 7u201, 8u191, and 11.0.1 are not vulnerable to this attack. This is not entirely the case. These versions are more resilient to the LDAP attack vector; however, they do not completely mitigate the vulnerability and are still susceptible to attack. To determine if a Java application is running a vulnerable version, a list of the impacted JAR files can be determined based on the hashes linked here.
The McAfee Enterprise ATR (Advanced Threat Research) team has been closely tracking this vulnerability since it became known. Our initial goal was to determine the ease of exploitation using the public PoC, which we have reproduced and confirmed. This was done using the public Docker container, and a client/server architecture leveraging both LDAP and RMI, along with marshalsec to exploit log4j version 2.14.1. We have posted a short video to demonstrate the reproduction for anyone who is struggling with this.
Going forward we plan to test variations of the exploit delivered using additional services such as DNS. We may update this document accordingly with results.
In the meantime, McAfee Enterprise has released a network signature KB95088 for customers leveraging NSP (Network Security Platform). The signature detects attempts to exploit CVE-2021-44228 over LDAP. This signature may be expanded to include other protocols or services, and additional signatures may be released to complement coverage.
Full coverage for this vulnerability can be tracked from our Security Bulletin here.

I think it’s fair to say that come to next Australia Day, there needs to be a special award category for parents of young children who survived home learning during the lockdowns. Let’s be honest – it’s been brutal! So many parents had to juggle their own full-time work, running a household, AND supervising a day’s worth of learning for often, multiple children! Research from Macquarie University showed that many parents spent up to 14 hours a week in their role as home learning managers and 9/10 parents reported the experience as, quite understandably, stressful! As a mum of older teens and young adults – who are usually self-sufficient – I’m in awe!
But the good news is – things are on the improve! Our vaccine rates are amongst the best in the world, so lockdowns have been lifted and, drum roll… kids are back at school! I’ve always been a big fan of trying to find the silver lining of any situation and I think there are many we can take away from our COVID experience, particularly when it comes to digital parenting. I know of so many parents who have completely rethought their approach to managing kids and technology since the pandemic hit because of their home learning experience.
So, in the spirit of sharing and caring, I thought I’d round up some of the best ‘aha’ moments from parents who were forced to become expert home learning managers over multiple lockdowns. And make sure you take notes because there are some great learnings that we can apply to our digital parenting journey.
If you have never been ‘all in’ with your kids’ use of technology for both learning and socializing, then you need to get over this ASAP. Technology is the lifeblood of your kids’ lives. It’s how they connect, nurture friendships, and organize their social lives. I also recommend parents try to see technology through the eyes of their kids NOT just through our more ‘mature’ lens. It’s the best way of truly understanding just what a huge role it plays in their day-to-day lives. And don’t forget that technology is almost always used to set up in-person catchups! So, please don’t demonize it, it will only push your kids away.
I totally appreciate that many parents didn’t choose to be home learning ‘managers’ however many have shared with me how they now feel far more involved in their child’s life because of the experience. Seeing first-hand how your child’s day works, overhearing their conversations with teachers and peers (courtesy of Zoom), and being blown away by your offspring’s tech skills has given many parents incredible insight into their child.
I know of parents who have noticed learning issues and friendship problems all as a result of their home learning manager role! There’s nothing like being able to nip something in the bud before it becomes a big issue! So, stay involved and you’ll reap the rewards!
Confession – I have never been one of those parents who proactively organized park visits, bushwalks, and exercise regimes for my kids. But many of the parents who managed young children through a lockdown and resorted to becoming personal trainers reported that it paid dividends. So, now lockdowns are (hopefully!) history, don’t forget about the benefits of getting your kids to move. It’s hard to be on a screen when you are walking the dog, playing a game of family cricket, or bushwalking. I know it’s time-consuming but it’s so worth it!
As of 2 years ago, the average Aussie household had 17 internet-connected devices in tow so it’s no wonder keeping abreast of all the devices in your household feels like a full-time job! But with kids continuing to use their devices for both study and socializing, it’s essential that you give each device a ‘once over’ to minimize risks and prevent issues arising down the track.
Ensuring all their software is up to date is a great place to start. Also check that the default password has been changed and that there is some top-shelf security software installed to protect the device and, most importantly, its user! And while you are there, why not also ensure that each of their online accounts has its own distinct password? If you think they could manage a password manager, then it might be time to introduce them to one? Check out McAfee’s True Key – I couldn’t manage without it!
I think you’d be hard-pressed to find many parents keen to return to home learning. In fact, I think there may even be a revolt if we had to go back! But, knowing we have picked up some ‘nuggets of gold’ along the way makes it a little feel a little better! So, please embrace technology – it’s a fantastic way of connecting with your kids. But of course, keep your family’s usage in check and minimize the risks by giving each device a once-over.
Happy Digital Parenting!

You open up your laptop and check the daily news. You see a headline stating that one of your favorite online retailers was breached and that thousands of their customers’ passwords were exposed. Data breaches like this frequently appear in the news, but many consumers don’t realize the implications these breaches have on their personal privacy. When data breaches occur, oftentimes billions of these hacked login credentials become available on the dark web, neatly packaged for criminals to download.1
Let’s dive into the differences between the deep web and the dark web, how cybercriminals use the dark web, and what you can do to protect your data.
You’ve probably heard of the deep and dark web but may not be aware of their differences.2 First, let’s start by noting that the dark web is always part of the deep web, but the deep web is not always the dark web.
The deep web refers to the pages on the internet that are not indexed in search engines, meaning that you can’t find them by performing a simple Google search. To access these pages, you have to know the exact address to the site and access it with specific software. Most personalized and password-protected sites appear on the deep web because they contain information that is not meant to be accessed by the general public. These sites include a user’s Netflix home page, password-protected sites for banking, and the internal sites of companies, organizations, and schools. These are all examples of legitimate areas of the deep web.
On the other hand, the dark web is the disreputable extension of the deep web. Like the deep web, the dark web also houses sites that are not indexed by search engines, but it also hides a user’s identity and location. It consists mostly of illegal products or content that could be harmful to organizations or the general public. Some examples include stolen credit card numbers, fake IDs, drugs, and hacking tools. To access the dark web, a user needs to download darknet software, the most popular being Tor.
Tor, which stands for “the onion routing project,” was developed by the U.S. Navy for the government in the mid-1990s. It was open-sourced in 2004, and that’s when it went public. Today, Tor is the dark web browser that the majority of people use to surf the internet anonymously. To do this, Tor hides a user’s IP address (or the unique address that identifies an internet-connected device or network) by bouncing their search request to multiple different locations. These bounces also referred to as relays, make it much harder for people to find users on the dark web.
Because of its ability to provide anonymity, the dark web is often tied to the world of cybercrime. Scammers frequently use the dark web to find software that allows them to access other people’s computers, banking credentials, Social Insurance Numbers, and credit card information. You may be wondering how all this private information ended up on the dark web in the first place. Oftentimes when a company is breached and their customers’ data is exposed, the hackers behind the breach will upload the stolen database to the dark web. This allows other cybercriminals to purchase the stolen information and use it to target users with other scams. Say that a criminal finds a database on the dark web that contains a bunch of personal email addresses. They can purchase the database and target every email address with a phishing campaign that contains malicious links that spread malware or attempt to trick users into handing over their username and password combinations.
Incorporating cybersecurity best practices into your daily life can help protect your data from hackers looking to take advantage of the data found on the dark web. Follow these tips to bring yourself greater peace of mind:
The chances of a hacker accessing your data are higher if you use the same credentials across different accounts. That’s why it’s important to use a strong, unique password for each of your online profiles. This minimizes the potential damage that could be done if a hacker does gain access to one of your accounts. You can also use a password manager with a built-in generator to make it easier for you to access and manage passwords. Enabling multi-factor authentication will also ensure that hackers cannot access your information using only your login credentials.
If you receive an email asking you to take immediate action, stop and think. Criminals often convey urgency in their phishing scams in the hopes that an unsuspecting user will click on a malicious link or hand over their personal details without considering the legitimacy of the message. Examine suspicious emails carefully to check for telltale signs of phishing, such as poor grammar, grainy logos, or bogus links. If an email claims to be from a well-known company or brand and asks for your credentials, claims that you need to update your password, or sends you a “free offer,” go directly to the source. Contact customer service through the company’s website (not the email) and inquire about the urgent request.
Be on the lookout for breach notices from relevant companies since they are often the first to know about a data breach impacting their online customers. Create news alerts for companies that have access to your information to stay notified of the latest events.
Additionally, create notifications for your bank and other financial accounts to monitor suspicious activity, such as unauthorized transactions or a drop in credit score. You will be better prepared to mitigate any cybersecurity threats with the right security software and knowledge of the latest risks.
Use a comprehensive security solution like McAfee Total Protection, which includes dark web monitoring for up to 10 email addresses. This software actively monitors the dark web for data breaches and exposed information. Personal details include but are not limited to your date of birth, email addresses, credit card numbers, and personal identification numbers. It also provides steps for remediation after a data breach to help you regain control and the integrity of your data and privacy. With a security solution like this in place, you can continue to live your connected life confidently.

You consider yourself a responsible person when it comes to taking care of your physical possessions. You’ve never left your wallet in a taxi or lost an expensive ring down the drain. You never let your smartphone out of your sight, yet one day you notice it’s acting oddly.
Did you know that your device can fall into cybercriminals’ hands without ever leaving yours? SIM swapping is a method that allows criminals to take control of your smartphone and break into your online accounts.
Don’t worry: there are a few easy steps you can take to safeguard your smartphone from prying eyes and get back to using your devices confidently.
First off, what exactly is a SIM card? SIM stands for subscriber identity module, and it is a memory chip that makes your phone truly yours. It stores your phone plan and phone number, as well as all your photos, texts, contacts, and apps. In most cases, you can pop your SIM card out of an old phone and into a new one to transfer your photos, apps, etc.
Unlike what the name suggests, SIM swapping doesn’t require a cybercriminal to get access to your physical phone and steal your SIM card. SIM swapping can happen remotely. A cybercriminal, with a few important details about your life in hand, can answer security questions correctly, impersonate you, and convince your mobile carrier to reassign your phone number to a new SIM card. At that point, the criminal can get access to your phone’s data and start changing your account passwords to lock you out of your online banking profile, email, and more.
SIM swapping was especially relevant right after the T-Mobile data breach.1 Cybercriminals stole millions of phone numbers and the users’ associated personal details. Criminals could later use these details to SIM swap, allowing them to receive users’ text or email two-factor authentication codes and gain access to their personal accounts.
The most glaring sign that your phone number was reassigned to a new SIM card is that your current phone no longer connects to the cell network. That means you won’t be able to make calls, send texts, or surf the internet when you’re not connected to Wi-Fi. Since most people use their smartphones every day, you’ll likely find out quickly that your phone isn’t functioning as it should.
Additionally, when a SIM card is no longer active, the carrier will often send a notification text. If you receive one of these texts but didn’t deactivate your SIM card, use someone else’s phone or landline to contact your wireless provider.
Check out these tips to keep your device and personal information safe from SIM swapping.
With just a few simple steps, you can feel better about the security of your smartphone, cellphone number, and online accounts. If you’d like extra peace of mind, consider signing up for an identity theft protection service like McAfee Identity Protection Service. McAfee, on average, detects suspicious activity ten months earlier than similar monitoring services. Time is of the essence in cases of SIM swapping and other identity theft schemes. An identity protection partner can restore your confidence in your online activities.

CVE-2021-20322: Of all the words of mice and men, the saddest are, “it was DNS again.”
For all our newcomers, welcome to the Advanced Threat Research team’s monthly bug report – a digest of all the latest and greatest vulnerabilities from the last 30-ish days based on merits just a tad more nuanced than sorting NVD by “CVSS > 9.0.” Instead, we focus on qualitative and experience-based analysis, relying on over 100 years of combined industry experience within our team.
To those who are returning after having read last month’s issue, I would like to congratulate you for being a Bug Report fan before it was cool – which it now most assuredly is, thanks in no small part to a litany of fascinating vulnerabilities. We encourage our veterans to stick around as long as possible, so that a year from now you can complain about how we’re washed up and how much better our early editions were.
Palo Alto Networks (PAN) firewalls that use its GlobalProtect Portal VPN running PAN-OS versions older than 8.1.17 are vulnerable to a cutting-edge, state-of-the-art style of vulnerability known as a “stack-based buffer overflow.” Although the vulnerable code is normally not reachable, when combined with an HTTP smuggling vulnerability, CVE-2021-3064 can be used to gain remote code execution, a remote shell, and even access to sensitive configuration data according to Randori Attack Team researchers. Randori discovered the vulnerability over a year ago but chose not to disclose it to PAN until September of this year, using it as part of its “continuous and automated red team platform” during the interim – I suppose we should be thankful that PAN has claimed in its security advisory that no evidence of exploitation of this vuln has been discovered, despite its age.
Absence of “in-the-wild” exploitation aside, we should also be grateful that the number of people who should care is rapidly dwindling (an ever-present theme of 2021). Randori initially reported over 70,000 internet-accessible PAN firewalls running vulnerable versions of PAN-OS according to Shodan, which it later amended to 10,000. As of this writing, that number has fallen to around 7,000. Even so, 7,000 vulnerable firewalls mean an even larger number of vulnerable clients at risk of an over-the-internet attack vector requiring zero authentication. Those connecting to PAN firewalls running on VMs have even greater cause for concern as these lack ASLR, a factoid I have chosen to add to my ever-growing “why is that a thing” list, right next to the Ghostbusters remake.
We suggest an experiment: open the Shodan search linked above and note the total number of devices running a vulnerable version of PAN-OS. Next, call up whoever manages your firewall and demand they power it down immediately – use threats if you must. Check the Shodan scan again: has the number gone down? If so, it’s probably time to update. If you’re an Arch user and the prospect of updating terrifies you, Palo Alto has also indicated that its signatures for Unique Threat IDs 91820 and 91855 should block exploitation of CVE-2021-3064.
Be sure to stay up to date on the latest CVEs – our security bulletins are a great resource for finding product information for all kinds of critical vulnerabilities.
Researchers at the University of California, Riverside have discovered a flaw in the way the Linux kernel handles “ICMP fragment needed” and “ICMP redirect” errors, allowing an attacker to quickly learn the randomized port number assigned to a UDP socket. What this description fails to convey is the big picture impact of this vulnerability, which is its use as a side-channel for the now-prehistoric DNS cache poisoning attack, in which an off-path malicious actor ‘poisons’ a DNS resolver’s cache with a false record, mapping a known domain (google.com) to an IP address of their choosing (98.136.144.138). Truly nefarious.
To be frank, just about everyone should be at least raising an eyebrow at this one. Although the researchers have indicated in their whitepaper that this particular side-channel only affects about 13.85% of open resolvers on the internet, it’s important to note that various security services rely on proof of domain ownership, including even the issuing of certificates, making the impact tremendous. Users of popular DNS service Quad9 have particular cause for concern, as the paper claims it falls under the vulnerable 13.85%. Linux users should also be concerned, and not just because their drivers refuse to work – DNS software such as BIND, Unbound, and dnsmasq running on their platform of choice are also vulnerable.
This is where things get tricky. DNS extensions that were standardized over two decades ago, such as DNSSEC and DNS cookies, should successfully mitigate this and all other DNS cache poisoning attack side channels. The unfortunate reality is that these features see very limited adoption due to backwards-compatibility concerns. While we wait for these dinosaurs holding back progress to die out, the authors of the aforementioned whitepaper have suggested some alternative mitigations, including enabling the IP_PMTUDISC_OMIT socket option, introducing additional randomization to the structure of the DNS exception cache, and configuring DNS servers with a singular default gateway to outright reject ICMP redirects. Further details can be found in section 8.4 of their paper.
Unfortunately, not every vulnerability can be adequately addressed by network security products, and this vulnerability happens to be one of those cases. Your best bet is to follow the mitigations mentioned above and keep your servers up to date.
Blacksmith, a name referring to both the vulnerability and the fuzzer created to exercise it, is a new implementation of the Rowhammer DRAM hardware vulnerability from 2014. The crux of Rowhammer is the use of high frequency read operations to induce bit flips in neighboring regions of physical memory, which can lead to the crossing of any security barrier if the attacker can massage memory so that critical data is stored in a vulnerable physical page. Modern DRAM hardware uses a technology called Target Row Refresh (TRR) to prematurely refresh regions of physical memory targeted by common Rowhammer attacks. Researchers at ETH Zurich and their associates discovered that TRR exploits the uniform nature of memory accesses used by existing Rowhammer attacks to “catch” them, and so devised a Rowhammer attack that used non-uniform accesses, arriving at CVE-2021-42114, which bypasses TRR and all other modern Rowhammer mitigations.
Everyone. Just about every common electronic device you can think of uses DRAM and of the DIMMs (RAM sticks) tested, the researchers did not find a single one that was completely safe. It might be easy to presume that hardware vulnerabilities such as this are academically fascinating but have little real-world impact, but research published since 2014 has shown Rowhammer attacks successfully escape JavaScript containers in the browser, cross VM boundaries in the cloud, and even achieve RCE across networks with high enough throughput. Perhaps the greatest tragedy of Blacksmith is that it arrived a month too late – it would have fit in perfectly with Halloween monsters like Freddy Krueger or Jason Voorhees who also see new iterations every few years and refuse to stay dead.
Hide your PC, hide your tablet, and hide your phone, ‘cause they’re hammerin’ everybody out there. Beyond that, there’s not much to be done besides wait for JEDEC to develop a fix and for DRAM manufacturers to begin supplying hardware with the new standard.
We at McAfee Enterprise are doing everything in our power to address this critical vulnerability. In other words, we’ll be waiting for that JEDEC fix right along with you.

Relying on the kindness of strangers is not an ideal strategy for CISOs and CIOs. And yet that is the precise position where most find themselves today while trying to battle cybersecurity issues across their supply chain. While these supply chains have plenty of their own challenges, such as global disruptions of distribution, our recent research shows that it’s the cybersecurity problems that will long survive for the long term.
It’s not as though enterprises rely on their partners any more today than they did ten years ago. Their needs have not changed and are unlikely to change, except those rare instances where an enterprise will choose to manufacture their own supplies rather than rely on partners. Consider, for example, Costco creating its own gigantic chicken farm. Other than outlier examples like this, partner reliance is relatively stable.
What is changing with the supply chain is how much system access is being granted to these partners. They are getting access they didn’t always get and are getting far deeper access as well. As technology has advanced to allow such access, enterprises have accepted.
Given the wide range of partners–suppliers, distributors, contractors, outsourced sales, cloud platforms, geographical specialists, and sometimes your own largest customers–the cybersecurity complexities are growing by orders of magnitude. In addition, the more integrations that enterprises accept, the higher the level that their risk is. To be more precise, the risk doesn’t necessarily grow with the number of partners as much as the risk grows with the number of partners whose cybersecurity environments are less secure than the enterprise’s own environment.
To even begin to craft a cybersecurity strategy to manage partners and a global supply chain, the enterprise CISO needs to have a candid understanding of what their partners’ security level truly is. That is tricky, given that many of those partners themselves do not have a good sense of how secure or insecure they are.
One suggestion is to revise contracts to make it a requirement for all partners to maintain a security level equal to the enterprise customer. The contract must not only specify penalties for non-compliance–and those penalties must be sufficiently costly that it makes no sense for a partner to take that chance–but it must specify means to determine and re-verify that security level. Surprise inspections and the sharing of extensive log files would be a start.
Otherwise, even the strictest security environment such as Zero Trust may be unable to plug supply chain holes due to sloppier partner security practices. Let’s say that a large enterprise retailer is working with a large consumer goods manufacturer as a partner. A good environment will start with strict authentication, making sure that the user from the partner is really that authorized user. The enterprise environment must also watch the user throughout the session to make sure the user doesn’t do anything suspicious. But if the partner has been breached, malware could sneak in through the secure tunnel and, if it’s not caught by the enterprise, there’s a problem and now they can be breached.
This is not hypothetical. Since the beginning of the pandemic, our research found that a vast majority of global enterprises (81 percent) said that they are seeing far more attacks since the beginning of COVID-19.
Almost every business is dependent on the supply chain, making it a prime target for cybercriminals looking to cause disruption and breach wider networks. As the holiday season approaches, we are already seeing a spike in consumer and business activity across the supply chain, making it a prime target for cybercriminals looking to target essential and lucrative services.
Attackers are going to continue to leverage the global supply chain as an initial entry vector, accessing the network through a trusted connection, system, or user. The fact that these attacks exploit trusted channels makes them very difficult to prevent or detect. As organisations continue their digital transformation, including ever-more cloud services, managed services and endpoint modernization, the risks of supply chain threats will increase as its prevalence as a vector does so.

This month it was disclosed that a Microsoft vulnerability that allows for local privilege elevation, previously patched in the November 2021 Patch Tuesday, is still exploitable and was not patched correctly. Using this vulnerability, threat actors with limited access to a compromised device can easily elevate their privileges to help spread laterally within the network.
Figure 1. MITRE ATT&CK Matrix for Windows Zero-Day in MVISION Insights
The vulnerability affects all supported versions of Windows, including Windows 10, Windows 11, and Windows Server 2022. At the time of writing, Microsoft has not released any updates or out-of-band patches to resolve it.
CVE-2021-41379 – Microsoft Windows Installer Elevation of Privilege Vulnerability
Bleeping Computer: New Windows zero-day with public exploit lets you become an admin
Bleeping Computer: Malware now trying to exploit new Windows Installer zero-day
McAfee Enterprise Global Threat Intelligence is currently detecting all known proof of concept exploits for this zero-day vulnerability as malicious.
McAfee Enterprise Endpoint Security (ENS) is currently detecting exploitation attempts and will quarantine the tools utilized to exploit this vulnerability as shown below.
Figure 2. Story Graph summary of exploitation detection by McAfee Enterprise ENS shown in MVISION ePO
MVISION Endpoint Detection and Response (EDR) is currently alerting to the activity of this exploitation as malicious and will note the MITRE techniques and any suspicious indicators related to the exploit attempts.
Figure 3. Detection of zero-day exploitation activity and techniques in MVISION EDR
MVISION Insights will provide the current threat intelligence and known indicators for exploitation of this vulnerability. MVISION Insights will also alert to detections that have been observed, and systems that require additional attention, to prevent widespread infection. MVISION Insights will also include Hunting Rules and Campaign Connections for threat hunting and further intelligence gathering of the threat activity and adversary.

On November 17, 2021, The US Cybersecurity & Infrastructure Security Agency (CISA) pushed an Alert entitled “Iranian Government-Sponsored APT Cyber Actors Exploiting Microsoft Exchange and Fortinet Vulnerabilities in Furtherance of Malicious Activities” which you need to pay attention to if you use Microsoft Exchange or Fortinet appliances. It highlights one Microsoft Exchange CVE (Common Vulnerability & Exposure), three Fortinet CVEs and a list of malicious and legitimate tools associated with this activity.
A few hours later our Advanced Threat Research (ATR) team published a new campaign in MVISION Insights under the name “Cyber Actors Exploiting Microsoft Exchange and Fortinet Vulnerabilities”. Immediately after, MVISION Insights started to provide near real-time statistics on the prevalence of the tools associated to this threat campaign by country and by sector.
Figure 1. MVISION Insights Global prevalence statistics for this campaign on Nov 19, 2021
In this blog I want to show you how you can operationalize the data linked to this alert in MVISION Insights together with your investigation and protection capabilities to better protect your organization against this threat.
MVISION Insights combines Campaigns and Threat Profiles in the same list, and you can change the order from “Last Detected” to “Last Added” as shown below.
Figure 2. List of MVISION Insights campaigns last added, with a selection of this campaign
On the left of figure 2, a color code shows you the severity assigned by the McAfee ATR team (Medium for this campaign), in the middle you can see whether we have seen detections of the analysed IOCs in your country or in your sector
If you are a McAfee Endpoint Security or IPS customer, on the right of figure 2 you can see whether you have had any detection of these IOCs by your McAfee Endpoint Security or IPS, or whether Endpoint Security has found exposed devices, or devices with insufficient Endpoint Security protection
As shown in figure 2, you can also click the campaign’s preview to read a short description, and the labels given by MVISION Insights:
In this case, you can see that CISA suspects this campaign to be associated with an APT threat group. It includes Ransomware behaviors. The labels also highlight the use of hacking tools and vulnerabilities which you can then view in the Campaign details. Last September we hosted a webinar focused on threat intelligence and protection against hacking tools.
The campaign description highlights the usual use of “devices encrypted with the Microsoft Windows BitLocker encryption feature”.
The campaign’s details also provide links to other sources, such as the CISA alert in this case.
Figure 3. Original CISA Alert used for this campaign
Once you have identified campaigns which could potentially hit you, you can evaluate your risk and whether you could be exposed because you could have:
Figure 4. List of Common Vulnerabilities and Exposures (CVEs) in this campaign’s details
If you are a McAfee Enterprise customer, the MVISION Insights Endpoint Security Posture checks whether you have enabled the necessary Endpoint Security features to have the best level of protection across your estate.
In the example below:
As seen previously, this lab environment has sufficient protection to detect the “Cyber Actors Exploiting Microsoft Exchange and Fortinet Vulnerabilities” campaign IOCs. However, to have full Endpoint protection, GTI, On-Access scan, Exploit Prevention, Real Protect and ATP must be enabled.
Figure 5. McAfee Endpoint Security Detection across all MVISION Insights campaigns
If you are a McAfee Endpoint Security or IPS customer, the detections related to the campaign’s IOCs are automatically mapped by MVISION Insights as shown in Figure 6.
Figure 6: McAfee Endpoint Security Detection across all MVISION Insights campaigns
You can also use your Endpoint Detection and Response (EDR) or SIEM solution to search for the presence of IOCs. As you can see below in Figure 7, we have categorized the IOCs, and in this instance:
If you are an MVISION EDR customer, you can automatically search for the presence of these IOCs across your estate from MVISION insights
Otherwise, you can export the IOCs and hunt them in your EDR, and SIEM, to examine the evidence of a potential compromise and escalate the case to a level2 or level3 analyst to run a full investigation.
Additionally, you can also use the MVISION APIs with a third-party Threat Intelligence Platform such as ThreatQ, ThreatConnect or MISP to orchestrate this threat hunting capability.
Figure 7: MVISION Insights IOCs for this campaign
You can also leverage the new Campaign Connections feature (Figure 8) to check whether these IOCs are also listed in other campaigns or threat profiles. Campaign collection uses graphs to connect all the MVISION campaigns, and threat profile data such as:
Figure 8: MVISION Insights Campaign connection using the IOCs of this campaign
Beyond the IOCs, your Threat Analysts can also leverage the MITRE Techniques and Tools related to this campaign and documented in MVISION Insights.
Figure 9: MITRE Techniques and Tools observed in MVISION Insights for this campaign
For example, here you could use MVISION EDR to look for the presence of:
Then you can quarantine suspected devices before running a full remediation. You can also check that your Endpoint Security solution has credential theft protection capabilities such as ENS credential theft protection.
If your organization hosts Microsoft Exchange or Fortinet appliances you will need to apply the recommended patching and upgrade recommendations. If you find indicators of compromise you might want to increase the priority of the tickets, asking the Fortinet and Microsoft Exchange administrators to fix these CVEs due to these suspicious activities.
To better assess your risk and exposure against this campaign you should review your current capabilities to:

The time to repurpose vulnerabilities into working exploits will be measured in hours and there’s nothing you can do about it… except patch
By Fred House
2021 is already being touted as one of the worst years on record with respect to the volume of zero-day vulnerabilities exploited in the wild. Some cite this as evidence of better detection by the industry while others credit improved disclosure by victims. Others will simply conclude that as the “upside” grows (e.g., REvil demanding $70M or Zerodium paying $2.5M for exploits) so too will the quantity and quality of players. But the scope of these exploitations, the diversity of targeted applications, and ultimately the consequences to organizations were notable as well. As we look to 2022, we expect these factors to drive an increase in the speed at which organizations respond.
If we look back at the past 12 months, we have seen notable breaches that highlight the need for organizations to improve response times:
ProxyLogon. When we first learned in 2020 that roughly 17,000 SolarWinds customers were affected, many reacted in shock at the pure scope of the compromise (it should be noted that a small subset of these customers are believed to have been compromised by follow-on activity). Unfortunately, 2021 brought its own notable increase in volume. Two weeks after Microsoft released a patch for ProxyLogon they reported that 30K Exchange servers were still vulnerable (less conservative estimates had the number at 60K).
ProxyShell. ProxyShell, a collection of three separate vulnerabilities (CVE-2021-31207, CVE-2021-34473 and CVE-2021-34523), was Exchange’s second major event of the year after ProxyLogon. In August, a Black Hat presentation outlining Exchange Server vulnerabilities was followed the next day by the release of an exploit POC, all of which had been patched by Microsoft months earlier in April/May. This analysis of data captured by Shodan one week after the exploit POC was released concluded that over 30K Exchange servers were still vulnerable, noting that the data may have underrepresented the full scope (i.e., Shodan hadn’t had time to scan the full Internet). In summary: patched in the Spring, exploited in the Fall. So, what happened in the interim you ask? The vulnerabilities in the Microsoft Client Access Service were exploited by threat actors who deployed web shells to execute arbitrary code on compromised mobile devices and web browsers.
vCenter Server. Another notable example occurred in May when VMWare released a patch for a remote code execution vulnerability in vCenter Server. This subsequent analysis concluded that over 4,000 systems remained vulnerable one week after the patch was released. Much like Exchange servers, where a typical company will only host a handful of servers, 4,000 vulnerable vCenter servers likely represents thousands of distinct companies.
Kaseya VSA. One bright spot may in fact be the Kaseya VSA breach. On July 2, REvil launched an unprecedented (anyone else tired of that word?) ransomware campaign against public facing VSA servers. Within two days the DIVD CSIRT reported that the number of exposed VSA servers had dropped from 2,200 to 140. Some estimates suggested that around 50 MSPs were compromised, affecting between 800 and 1500 business. While this doesn’t sound like much of a bright spot, patching 94% of the affected systems in two days surely helped reduce the success of REvil copycats.
So, what can we take away from all of this? Well, attackers and security researchers alike will continue to hone their craft until weaponized exploits and POCs are expected within hours of vulnerability disclosure. In turn however, and largely driven by the increased consequences of compromise, we can also expect renewed diligence around asset and patch management. From identifying public facing assets to quickly deploying patches despite potential business disruption, companies will have a renewed focus on reducing their “time to patch.”
Still not convinced? Well, the US government is. Checkout Binding Operational Directive 22-01 published on November 3rd which compels all federal agencies to remediate known exploited vulnerabilities in two weeks or sooner “in the case of grave risk to the Federal Enterprise”. It’s no coincidence that CISA’s known exploited vulnerabilities catalog, which catalogues the vulnerabilities that must be remediated, includes every one of our examples above with a two-week remediation deadline. If the US government can do it, you can too!

In the October 2021 Threat Report, McAfee Enterprise ATR provides a global view of the top threats, especially those ransomware attacks that affected most countries and sectors in Q2 2021, especially in the Public Sector (Government).
In June 2021 the G7 economies urged countries that may harbor criminal ransomware groups to take accountability for tracking them down and disrupting their operations. Let’s review the high severity campaigns and threat profiles added to MVISION Insights recently.
Conti has been one of the top Ransomware groups in 2021, including a new campaign reported in September 2021. As mentioned earlier in this report, the public sector seems to be the sector most affected by Ransomware attacks. McAfee Enterprise provides regular publications on the strategies to defend against ransomware, such as this blog.
CVE-2021-40444 Microsoft MSHTML Remote Code Execution Vulnerability
This is a serious Microsoft Office vulnerability reported in September 2021 by Microsoft, McAfee Enterprise and other sources. The MVISION Insights heat map shows the prevalence of the Indicators of Compromise (IOCs) associated with this threat in the first half of October 2021.
Although Microsoft has provided guidance on a workaround, it can be challenging for many public sector organizations to deploy these patches quickly. To help you be more agile, McAfee Enterprise has released its own guidance leveraging ENS, EDR and NSP.
Microsoft Office vulnerabilities are commonly exploited in the early phases of the attack lifecycle. BazarLoader, mentioned earlier with the Conti Ransomware, has also been used with Word and Excel documents. In the MITRE Enterprise ATT&CK framework this technique is known as T1203, which we can find in 177 campaigns and threat profiles in MVISION Insights.
APT41 is a state sponsored threat group linked to China and associated with multiple campaigns, including a new campaign reported in September 2021. Although Ransomware is currently the main cyber threat type which hits the news, state sponsored threat groups are equally concerning, especially in the public sector for organizations with sensitive government and citizen data, which could be potentially exploited by a foreign nation like China.
In the second part of this report, we highlight how you can leverage the data from MVISION Insights to find traces of these attacks to enhance your level of protection.
In the October 2021 Threat Report, McAfee Enterprise ATR also assessed the prevalence of Cloud Threats, identifying the US Government sector as one of the top 10 verticals affected.
Many governments are moving quickly to adopt cloud technologies to bring services for their citizens, for collaboration and cost savings.
Inadequate readiness to address cloud security has been the primary contributor of these threats. Several cloud-native controls exist to protect sensitive data from loss or theft in real time, such as:
In the second part of this report, we want to give you some guidance on how you can operationalize this threat intelligence data to better protect your networks. MVISION Insights can help operationalize McAfee Enterprise Threat Intelligence data by providing risk assessment against threats affecting you, protective guidance and integrating with other tools to share threat data.
Let’s take the previous example of the Conti Ransomware Threat Profile. Below you can see how MVISION Insights provides:
1. A short description with the list of CVEs linked to this threat profile, the minimum version of McAfee Enterprise ENS AMcore content to be correctly protected against this threat, detections in your environment and on which device.
2. The list of related campaigns, the devices with unresolved detections related to these campaigns or those with insufficient protections.
3. The list of MITRE techniques and tools, which provide a universal and agnostic overlay of the threats, as well as details on the observables specific to this threat profile for each MITRE technique.
4. The list of IOCs with filters, IOC attributes, and IOC export features which you can use to share them with your other solutions, such as your SIEM, and which you can also share with other public sector entities. We also provide a direct integration with MVISION EDR. Alternatively, you can leverage the APIs to automate the exchange of IOCs.
If you find devices with these IOCs in MVISION EDR you can take immediate remote actions such as quarantine the device, kill the process, remove the files, or run custom scripts.
You can also use MVISION EDR for more advanced threat hunting such as searching for specific MITRE techniques in all MVISION EDR alerts …
… or in the MVISION EDR monitoring view which automatically groups the alerts.
5. MVISION Insights also provides hunting rules created by McAfee Enterprise Threat Intelligence experts using Yara, Sigma and McAfee Enterprise ENS expert rules.
6. A proactive assessment of your Endpoint and Cloud security posture score with guidance on the configuration changes which you should follow to ensure that your McAfee Enterprise Endpoint and Cloud solutions are protecting you with their full capabilities.
7. And all this, with more than 1,200 threat campaigns and threat profiles
MVISION APIs give you the ability to integrate and to exchange this extensive Threat Intelligence data with your SOC tools, including Threat Intelligence Platforms (TIPs) and Security Orchestration Automation and Response (SOAR).
These integrations can be used both in Internet-facing and closed networks. For advanced Threat Intelligence teams, our Advanced Program Group (APG) provides “Threat Intelligence as a Service” (INTAAS) including:
To conclude, here is a summary of the use cases you can achieve with MVISION Insights in the public sector:

In life, regret tends to take on many shapes and forms. We often do not heed the guidance of the common anecdotes we hear throughout our days and years. From “look before you leap” to “an apple a day keeps the doctor away” – we take these sayings in stride, especially when we cannot necessarily provide proof of their veracity!
One particular trope that may incite ire, frustration, or regret when applied to enterprise security is – “once bitten, twice shy.”
In its very literal sense, we’re taught that if we’re bitten by something once – whether that be dog or security breach – we’re innately cautious or fearful of falling into a similar scenario. With dogs or any animal, we may pivot our behavior to avoid sharp teeth. However, with security breaches, many enterprises continue to be blindsided by “bites” – despite believing they’ve taken the utmost of caution to protect against them.
There is a clear disconnect between enterprise-preparedness and the severity of today’s threat landscape. We continue to see that no enterprise is immune to threats and breaches, with ransomware campaigns continuing to get more sophisticated and prevalent. We’re also seeing cyber criminals work together, banding as an enterprise themselves sharing common tools and knowledge. This means, as cyber criminals become more business-savvy, operational, and efficient – the enterprises they look to attack need to consistently be one step ahead to anticipate and prevent breaches.
The term digital transformation is not new by any means, but it needs to be newly approached through a security-first lens. For successful digital transformation to occur today, major industries need to focus on superior prevention against threats.
It’s time for business leaders to stop focusing on the “breach of the month” and more on building security into the fabric of their organizations so they’re not the next victims. For this to happen, it is imperative to break down silos of threat and information intelligence across the organization, enabling a collaborative, holistic, and strategic approach to securing the business.
Additionally, as we’re seeing more prevalent and sophisticated attacks, enterprises need to lean into the transformative technologies that can keep up with evolving techniques. AI provides for personalization of security – a key advantage as it can prioritize detection and response to allow organizations to focus on growth outcomes instead of spending time recouping lost data, customers, revenue, efficiencies, or more that can come at the expense of a threat or breach.
Placing security at the forefront of strategies can unleash the full potential of what digital transformation can make possible. With this approach and a mindset focused on prevention and cyber-readiness as the catalyst aiding true digital and business transformation, we have the power to turn the headlines around. It is time for enterprises to bite back, and the criminals to shy away.

Can thieves steal identities with only a name and address?
In short, the answer is “no.” Which is a good thing, as your name and address are in fact part of the public record. Anyone can get a hold of them. However, because they are public information, they are still tools that identity thieves can use.
If you think of your identity as a jigsaw puzzle, your name and address are the first two pieces that they can use to build a bigger picture and ultimately put your identity at risk.
With that, let’s look at some other key pieces of your identity that are associated with your name and address—and what you can do to protect them.
For starters, this information is so general that it is of little value in of itself to an identity thief. Yet a determined identity thief can do a bit of legwork and take a few extra steps to use them as a springboard for other scams.
For example, with your name and address a thief could:
There are volumes of public information that are readily available should someone want to add some more pieces to your identity jigsaw puzzle, such as:
In the U.S., the availability of such information will vary from state-to-state and different levels of government may have different regulations about what information gets filed—in addition to whether and how those reports are made public. Globally, different nations and regions will collect varying amounts of public information and have their own regulations in place as well. More broadly, though, many of these public databases are now online. Consequently, accessing them is easier than the days when getting a hold of that information required an in-person visit a library or public office.
Thieves can gain additional information about you from other online sources, such as data brokers. And data brokerage is a big business, a global economy estimated at $200 billion U.S. dollars a year. What fuels it? Personal information, representing thousands of data points on billions of people scraped from public records, social media, smartphone apps, shopper loyalty cards, third-party sources, and sometimes other data broker sites as well.
The above-the-board legal intent of data broker sites is to sell that information to advertisers so that they can create highly targeted campaigns based on people’s behaviors, travels, interests, and even political leanings. Others such as law enforcement officials, journalists, and others who are conducting background checks will use them too.
On the dark side, hackers, scammers, and thieves will buy this information as well, which they can use to commit identity theft and fraud. The thing is, data brokers will sell to anyone. They don’t discriminate.
Phishing attacks aren’t just for email, texts, and direct messages. In fact, thieves are turning to old tricks via old-fashioned physical mail. That includes sending phony offers or by impersonating officials of government institutions, all designed to trick you into giving up your personally identifiable information (PII).
What might that look like in your mailbox? They can take the form of bogus lottery prizes that request bank information for routing (non-existent) winnings. Another favorite of scammers are bogus tax notifications that demand immediate payment. In all, many can look quite convincing at first blush, yet there are ready ways you can spot them. In fact, many of the tips for avoiding these physical mail phishing attacks are the same for avoiding phishing attacks online, which we outline in detail here.
Recently, I’ve seen a few news stories like this where thieves reportedly abuse the change-of-address system with the U.S. Postal Service. Thieves will simply forward your mail to an address of their choosing, which can drop sensitive information like bank and credit card statements in their mailbox. From there, they could potentially have new checks sent to them or perhaps an additional credit card—both of which they can use to drain your accounts and run up your bills.
The Postal Service has mechanisms in place to prevent this, however. Among which, the Postal Service will send you a physical piece of mail to confirm the forwarding. So, if you ever receive mail from the Postal Service, open it and give it a close look. If you get such a notice and didn’t order the forwarding, visit your local post office to get things straightened out. Likewise, if it seems like you’re missing bills in the mail, that’s another good reason to follow up with your post office and the business in question to see if there have been any changes made in your mail forwarding.
So while your name and address are out there for practically all to see, they’re largely of little value to an identity thief on their own. But as mentioned above, they are key puzzle pieces to your overall identity. With enough of those other pieces in hand, that’s where an identity thief can cause trouble.
Other crucial pieces of your identity include:
Let’s start with the biggest one. This is the master key to your identity, as it is one of the most unique identifiers you have. As I covered in my earlier blog on Social Security fraud, a thief can unlock everything from credit history and credit line to tax refunds and medical care with your Social Security or tax ID number. In extreme cases, they can use it to impersonate you for employment, healthcare, and even in the event of an arrest.
You can protect your Social Security Number by keeping it locked in a safe place (rather than in your wallet) and by providing your number only when absolutely necessary. For more tips on keeping your number safe, drop by that blog on Social Security fraud I mentioned.
Thieves have figured out ways of getting around the fact that IDs like these include a photo. They may be able to modify or emulate these documents “well enough” to pull off certain types of fraud, particularly if the people requesting their bogus documents don’t review them with a critical eye.
Protecting yourself in this case means knowing where these documents are at any time. (With passports, you may want to store those securely like your Social Security or tax ID number.) Also be careful when you share this information, as the identifiers on these documents are highly unique. If you’re uncomfortable with sharing this information, you can ask if other forms of ID might work—or if this information is really needed at all. Also, take a moment to make copies of these documents and store them in a secure place. This can help you provide important info to the proper authorities if they’re lost or stolen.
With data breaches large and small making the news (and many more that do not), keeping a sharp eye on your accounts is a major part of identity theft prevention. We talk about this topic quite often, and it’s worth another mention because protecting these means protecting yourself from thieves who’re after direct access to your finances and more.
Secure your digital accounts for banking, credit cards, financials, and shopping by using strong, unique passwords for each of your accounts that you change every 60 days. Sound like a lot of work? Let a password manager do it for you, which you can find in comprehensive online protection software. By changing your strong passwords and keeping them unique can help prevent you from becoming a victim if your account information is part of a breach—by the time a crook attempts to use it, you may have changed it and made it out of date.
In addition to protecting the core forms of identity mentioned above, a few other good habits go a long way toward keeping your identity secure.
By protecting your devices, you protect what’s on them, like your personal information. Comprehensive online protection software can protect your identity in several ways, like creating and managing the strong, unique passwords we talked about and providing further services that monitor and protect your identity—in addition to digital shredders that can permanently remove sensitive documents (simply deleting them won’t do that alone.) Further, it can monitor your identity and monitor your credit, further protecting you from theft and fraud.
Identity theft where thieves dig through trash or go “dumpster diving” for literal scraps of personal info in bills and statements, has been an issue for some time. You can prevent it by shredding up any paper medical bills, tax documents, and checks once you’re through with them. Paper shredders are inexpensive, and let’s face it, kind of fun too. Also, if you’re traveling, have a trusted someone collects your mail or have the post office put a temporary hold on your mail. Thieves still poach mail from mailboxes too.
Getting statements online cuts the paper out of the equation and thus removes another thing that a thief can physically steal and possibly use against you. Whether you use electronic statements through your bank, credit card company, medical provider, or insurance company, use a secure password and a secure connection provided by a VPN. Both will make theft of your personal info far tougher on identity thieves.
A VPN is a Virtual Private Network, a service that protects your data and privacy online. It creates an encrypted tunnel to keep you more anonymous online by masking your IP address, device information, and the data you’re passing along that connection. In this way, it makes if far more difficult for advertisers, data brokers, and bad actors to skim your private information—in addition to shielding your information from crooks and snoops while you’re banking, shopping, or handling any kind of sensitive information online.
Give your statements a close look each time they come around. While many companies and institutions have fraud detection mechanisms in place, they don’t always catch every instance of fraud. Look out for strange purchases or charges and follow up with your bank or credit card company if you suspect fraud. Even the smallest charge could be a sign that something shady is afoot.
This is a powerful tool for spotting identity theft. And in many cases, it’s free to do so. In the U.S., the Fair Credit Reporting Act (FCRA) requires the major credit agencies to provide you with a free credit check at least once every 12 months. Canada provides this service, and the UK has options to receive free reports as well, along with several other nations. It’s a great idea to check your credit report, even if you don’t suspect a problem.
If the thought of your personal info being bought and sold puts you off, there’s something you can do about it. Our Personal Data Cleanup service can scan some of the riskiest data broker sites and show you which ones are selling your personal info. It also provides guidance on how you can remove your data from those sites, and with select products, it can even manage the removal for you.
While thieves need more than just your name and address to commit the overwhelming majority of fraud, your name and address are centerpieces of the larger jigsaw puzzle that is your overall identity.
And the interesting thing is your puzzle gets larger and larger as time goes on. With each new account you create and service that you sign into, that’s one more piece added to the puzzle. Thieves love getting their hands on any pieces they can because with enough of them in place they can try and pull a fast one in your name. By looking after each piece and knowing what your larger jigsaw puzzle looks like, you can help keep identity thieves out of your business and your life.

The malware landscape is growing more complex by the minute, which means that no device under your family’s roof—be it Android, iPhone, PC, or Mac—is immune to an outside attack. This reality makes it possible that one or more of your devices may have already been infected. But would you know it?
According to 2021 statistics from the Identity Theft Resource Center (ITRC), the number of data breaches reported has soared by 17 percent over last year. In addition, as reported by McAfee, cybercriminals have been quick to take advantage of the increase in pandemic connectivity throughout 2020. McAfee Labs saw an average of 375 new threats per minute and a surge of hackers exploiting the pandemic through COVID-19 themed phishing campaigns, malicious apps, malware, and more. With Black Friday and Cyber Monday now at hand, we can count on even more new threats.
Often, if your device has been compromised, you know it. Things get wonky. However, with the types of malware and viruses now circulating, there’s a chance you may not even realize it. The malware or virus may be working in the background sending usage details or sensitive information to a third party without disrupting other functions. So, be on the lookout for these tell-tale signs.
If you discover a family device has been compromised, there are several things you can do. 1) Install security software that will help you identify the malware so you can clean your device and protect yourself in the future. 2) Delete any apps you didn’t download, delete risky texts, delete browsing history and empty your cache. 3) In some situations, malware warrants that you wipe and restore your device (Apple or Android) to its original settings. Before doing so, however, do your research and be sure you’ve backed up any photos and critical documents to the cloud. 4) Once you’ve cleaned up your devices, be sure to change your passwords.
The surge in malware attacks brings with it a clear family mandate that if we want to continue to live and enjoy the fantastic benefits of a connected life, we must also work together at home to make online safety and privacy a daily priority.

McAfee Enterprise and FireEye recently teamed to release their 2022 Threat Predictions. In this blog, we take a deeper dive into cloud security topics from these predictions focusing on the targeting of API services and apps exploitation of containers in 2022.
Recent statistics suggest that more than 80% of all internet traffic belongs to API-based services. It’s the type of increased usage that grabs the attention of threat developers hunting for rewarding targets.
Feature-rich APIs have moved from being just a middleware to applications and have evolved to become the backbone of most modern applications that we consume today. Examples include:
In most cases, attacks targeting APIs go undetected as they are generally considered as trusted paths and lack the same level of governance and security controls.
The following are some of the key risks that we see evolving in the future:
Gaining visibility into application usage with the ability to look at consumed APIs should be a priority for organizations, with the goal of ultimately having a risk-based inventory of accessed APIs and a governance policy to control access to such services. Having visibility of non-user-based entities within the infrastructure such as service accounts and application principles that integrate APIs with the wider enterprise eco-system is also critical.
For developers, developing an effective threat model for their APIs and having a Zero Trust access control mechanism should be a priority alongside effective security logging and telemetry for better incident response and detection of malicious misuse.
Containers have become the de facto platform of modern cloud applications. Organizations see benefits such as portability, efficiency and speed which can decrease time to deploy and manage applications that power innovation for the business. However, the accelerated use of containers increases the attack surface for an organization. Which techniques should you look out for, and which container risk groups will be targeted? Exploitation of public-facing applications (MITRE T1190) is a technique often used by APT and Ransomware groups. MITRE T1190 has become a common entry vector given that cyber criminals are often avid consumers of security news and are always on the lookout for a good exploit. There are numerous past examples in which vulnerabilities concerning remote access software, webservers, network edge equipment and firewalls have been used as an entry point.
The Cloud Security Alliance (CSA) identified multiple container risk groups including:
How do you protect yourself? Recommended mitigations include bringing security into the DevOps process through continuous posture assessment for misconfigurations, checks for integrity of images, and controlling administrative privileges. Use the Mitre ATT&CK Matrix for Containers to identify gaps in your cloud security architecture.

November 11 marks Veterans Day in the United States and Remembrance Day across Europe and beyond. Wherever you may be on this 11th day of the 11th month, on the 11th hour, please be thankful to all our Veterans for their service and sacrifice. We would like to take a moment to reflect and honor some of our McAfee Enterprise employees who served.
Shannon Clancy joined October 5, 2003 and was a Major in the United States Marine Corps
Kevin Benton enlisted ten days after high school (mid 1980’s) and was in the US Army as an E4/Specialist
Kevin Suares enlisted in the US Air Force on November 1, 1994, after four year’s he was a Senior Airman (E-4)
Clancy: I had always had a niggling in the back of my mind that I wanted to be a Marine (My father served as a Marine in Vietnam), and then September 11, 2001 happened and it solidified my choice. I wanted to be the best, and everyone knows Marines are the best.
Benton: The world was bigger than my little hometown and I wanted to travel the world. Plus, I was clearly the smartest person in my house at 18 years old, so I showed my parents how smart I was.
Suares: I needed money for college and needed some direction in life. Initially I considered the Navy, as I am a former Sea Scout. I spoke to a Navy recruiter and was ready to sign up. He sent me across the hall to “get a different perspective” from the Air Force recruiter (which I was also considering) and after a 20-minute conversation where we talked about options in the Air Force, Air Force training, how the Air Force encourages higher education and AF ethos, I changed my mind. Biggest regret of that Navy recruiter’s career! The next week I scored 97 out of 99 in the Armed Services Vocational Aptitude Battery (ASVAB) making me eligible for almost any job.
Clancy: I remember my first day being total chaos. Not knowing the (now) simplest things like how to wear your cover (hat), blouse your trousers, align your belt, etc. Things that seem small and silly but were in fact critical lessons in attention to detail that have carried with me throughout service and life.
Benton: On the first day, I was tired and nervous about not having any idea of what was happening or what to do. The last day was filled with wildly mixed emotions! I made some great friends from all walks of life, and I was ready to get on with my life by attending college on the GI Bill, but I hadn’t yet lived on my own. I recall driving off the base and wondering if I should drive north or south on the Pacific Coast Highway; ultimately, I drove North and have never regretted the decision.
Suares: I remember on my first full day being woken up at 4:30 AM after going to bed around 1:30 AM, in a new environment to a metal trash can being hit repeatedly with a baton and words I can’t repeat here. On my last day, my supervisor still made me work the whole day, ending in a small ceremony where I was presented with a few token gifts (which I still have.) I wrote my flight a quick email saying goodbye then left for home. Not going to lie – I had tears in my eyes as I left the building.
Clancy: My most memorable experience was my deployment to Iraq. There was a pause in operations on Thanksgiving and I got to play soccer with some of the Marines. It was a very “normal” thing in a place where there wasn’t much normal. I don’t miss much (because there is a lot of nonsense that also goes on), but what I do miss is the camaraderie and sense of belonging. You don’t question who you are or what your purpose is while you serve.
Benton: Being in the infantry, I recall experiencing some of the toughest, most physically demanding moments in my life, then experiencing shear exhaustion when reaching the end of a march or landing in a hot zone, only to have a few laughs with the guys to your left and right, toggling thru each other’s life stories. No one cared where you were from or the color of our skin or whether you had any money. I’ll never forget the laughs and storytelling as we were all experiencing the same things at the same time. Come to find out, we were forming bonds for life.
Suares: My most pleasant memory wastaking my grandfather out to dinner in uniform for his 70th birthday. He was so proud that he was speechless for once. If you knew him, that was a really big deal. But my saddest memory was hearing the rifle salute at a friend’s funeral. Each volley cut me to the bone.
Clancy: I usually call my dad. Veterans day buddies right up to the Marine Corps Birthday, so there is no shortage of celebrations or drinks to be shared among Marines. This year has been extremely difficult on veterans; so, I think I’ll text a few friends I haven’t heard from in a while. I encourage everyone to reach out to one you know, just to check in and say hi. It goes a lot further than you might think.
Benton: Our little town holds a ceremony at our local cemetery. I’ve attended with my family for years, afterwards nearly always telling my kids stories of my service to my country and the pride I feel when seeing our flag and all that it stands for.
Suares: Usually with service to others. Occasionally I may go out to dinner with family, but most times I used to be involved in giving talks to youth groups, schools, etc. or donating time to other Veterans causes. I proudly served my country – and would do it again if asked – but I feel that I am not owed anything. The day should be about recognizing the living service member (past or present) and honoring us all.

This month brings us yet another critical RCE (Remote Code Execution) bug found in the RDP (Remote Desktop Protocol) Client which has also been ported to the Hyper-V Manager “Enhanced Session Mode” feature. User interaction is a prerequisite since the vulnerability lies within the RDP client, requiring a victim to connect to a malicious RDP server.
This RCE bug is very closely related to CVE-2021-34535 and to CVE-2020-1374 , where there is a heap-based buffer overflow in mstscax.dll due to an attacker-controlled payload size field. The vulnerability can be triggered via the RDP Smart Card Virtual Channel Extension feature [MS-RDPESC], by leveraging the existing local RDPDR static virtual channel setup between the client and server. The RDP Smart Card Virtual Channel Extension feature [MS-RDPESC] functionality was leveraged in the “EsteemAudit” Exploit released by the “Shadow Brokers,” but that vulnerability targeted the RDP server and not the client. The functionality being exploited here is the ability to share a smart card reader between the client and server. The destination buffer intended for the IOCTL (I/O control) call to locate each host smart card reader is a fixed size, but the user-controlled size field can be altered to cause the client to perform an OOB (Out of Bounds) write. Seeing how simple it is to trigger this vulnerability, our team decided to mutate the test case to verify whether any other IOCTLs within the [MS-RDPESC] specification are vulnerable. Enumerating through the 60 other IOCTL calls tied to the smart card reader, we were able to find two additional unique crashes. All vulnerabilities discovered have been patched in the latest version of the mstscax.dll, which shows that the fix for this bug has mitigated other potentially vulnerable functions. The patched mstscax.dll now simply verifies that the bytes received over the wire do not exceed the user-supplied size field; it does this at the IOCTL dispatch table level before any IOCTL functions are called, so the single validation is applied to all IOCTLs.
This vulnerability has a CVSS (Common Vulnerability Scoring Standard) score of 8.8, dropped down from 9.8 because it requires user interaction in that a victim RDP client must connect to a malicious server.
This bug has the same attack scenario as that of CVE-2021-34535, which we also analyzed in depth:
We have seen a regular cadence of critical RDP vulnerabilities since BlueKeep (CVE-2019-0708), but what distinguishes the two vulnerabilities CVE-2021-38666 and CVE-2021-34535 is that they impact Hyper-V Manager “Enhanced Session Mode” and can thus be leveraged for guest-to-host escapes. While we do not rate these vulnerabilities as critical in the same manner as past RDP server-side RCE vulnerabilities, we are now clearly starting to see a trend of vulnerabilities emerging which impact Hyper-V Manager due to the porting of RDP. We recommend patching as a top priority as threat actors will potentially look to weaponize this common protocol for guest-to-host escapes on Windows 10 Hyper-V.
Microsoft has published a Knowledge Base article for this issue here with information regarding patching this vulnerability. As always, we recommend patching as a first course of action and we will continue to monitor this vulnerability for any exploitation in the wild.

The holiday season is upon us, and many are preparing to celebrate with family and friends both near and far. While we tend to look at consumer tendencies during the holidays, the season also presents a significant challenge to industries coping with the increase in consumer demands. McAfee Enterprise and FireEye recently conducted a global survey of IT professionals to better understand their cyber readiness, especially during peak times like the holiday season, and the impact the pandemic has had on their business. Most notably, 86% of organizations are anticipating a moderate-to-substantial increase in demand during the 2021 holiday season. The question is: Are they ready for that demand?
This year, the “everything shortage” is real – from a drop in available workforce to limited supplies to lack of delivery services. This creates an urgency for organizations to have actionable security plans and to effectively contain and respond to threats. Supply chain and logistics, e-commerce and retail, and the travel industry traditionally experience holiday seasonal increases in consumer and business activity, making them more vulnerable to cyber threats and leaving business, employee, and consumer data at risk. Here’s a statistical snapshot of these affected industries and how they can prepare for the anticipated increase in seasonal risks:
According to BCI’s Supply Chain Resilience Report 2021, 27.8% of organizations reported more than 20 supply chain disruptions during 2020, up from just 4.8% reporting the same number in 2019. The loss of manufacturing and logistics capacity, and employee-power in 2021 are expected to increase demand for goods, creating the perfect attack vector for cybercriminals: a potentially weak and vulnerable infrastructure to break through. Supply chain managers must identify risks, understand the potential downstream effects of a security breach or cyberattack, and prepare response plans so they can act quickly in the event of an incident.
According to Adobe’s 2021 Digital Economy Index, global online spending is expected to increase by 11% in 2021 to $910 billion during the holiday season. With store closures and increases in online shopping, along with limited product availability and concerns about shipping, this industry is faced with more threats than before. According to McAfee Enterprise COVID-19 dashboard, the global retail industry accounts for 5.2% of the total detected cyber threats. Such threats include compromised payment credentials and cloud storage, as well as other forms of retail fraud and theft.
Cyber threats aren’t new to the travel industry with airports, airlines, travel sites and ride-sharing apps having been victims in years past. However, what sets this year apart is the travel industry enduring a holding pattern caused by pandemic-related health concerns and travel restrictions. According to the International Air Transport Association (IATA), coronavirus-related loss estimates for 2020 total $137.7 billion—with total industry losses in 2020-2022 expected to reach $201 billion. As demand for holiday travel is expected to increase over the coming months, cyber criminals are watching closely for vulnerabilities as the industry battles new related challenges – labor shortages, supply chain issues, travel bans, and vaccination requirements.
McAfee Enterprise and FireEye threat findings unwrap the imminently crucial need for organizations to prioritize and strengthen their cybersecurity architecture through the holidays and end of 2021. Our research indicates that 81% of global organizations experienced increased cyber threats and 79% experienced downtime in the wake of previous cyberattacks.
While IT professionals know cyber threats have intensified, the findings prove that many organizations have not effectively prioritized security during COVID-19:
Organizations can be proactive in defending their networks, data, customers, and employees against the anticipated increase in holiday cybercrime by implementing security measures including, but not limited to:
In addition, enterprises and commercial businesses can implement cloud-delivered security with MVISION Unified Cloud Edge (UCE) and FireEye Extended Detection and Response (XDR).

McAfee Enterprise and FireEye recently released its 2022 Threat Predictions. In this blog, we take a deeper dive into a Game of Thrones power struggle among Ransomware-as-a-Service bad actors in 2022.
For several years, ransomware attacks have dominated the headlines as arguably the most impactful cyber threats. The Ransomware-as-a-Service (RaaS) model at the time opened the cybercrime career path to lesser skilled criminals which eventually led to more breaches and higher criminal profits.
For a long time, RaaS admins and developers were prioritized as the top targets, often neglecting the affiliates since they were perceived as less skilled. This, combined with the lack of disruptions in the RaaS ecosystem, created an atmosphere where those lesser-skilled affiliates could thrive and grow into very competent cybercriminals, eventually with a mind of their own.
In a response to the Colonial Pipeline attack, the popular cybercrime forums have banned ransomware actors from advertising. Now, the RaaS groups no longer have a third-party platform on which to actively recruit, show their seniority, offer escrow, have their binaries tested by moderators, or settle disputes. The lack of visibility has made it harder for RaaS groups to establish or maintain credibility and will make it harder for RaaS developers to maintain their current top tier position in the underground.
These events have undermined their trusted position. Ransomware has generated billions of dollars in recent years and it’s only a matter of time before more individuals who believe they aren’t getting their fair share become unhappy.
The first signs of this happening are already visible as described in our blog on the Groove Gang, a cyber-criminal gang that branched off from classic RaaS to specialize in computer network exploitation (CNE), exfiltrate sensitive data and, if lucrative, partner with a ransomware team to encrypt the organization’s network. McAfee Enterprise ATR believes, with high confidence, that the Groove gang is associated with the Babuk gang, either as a former affiliate or subgroup. These cybercriminals are happy to put aside previous Ransomware-as-a-Service hierarchies to focus on the ill-gotten gains to be made from controlling victim’s networks, rather than the previous approach which prioritized control of the ransomware itself.
Trust in a few things remains important even among cybercriminals underground, such as keeping your word and paying people what they deserve. Cybercriminals aren’t immune from feeling like employees whose contributions aren’t being adequately rewarded. When this happens, these bad actors cause problems within the organization. Ransomware has been generating billions of dollars in recent years and with revenue like that, it was inevitable that some individuals who believe they aren’t getting their fair share become unhappy and let the cybercrime world know it.
Recently, a former Conti affiliate was unhappy with their financial portion and decided to disclose the complete Conti attack playbook and their Cobalt Strike infrastructure online. In the past, McAfee ATR has been approached by individuals affiliated with certain RaaS groups expressing grudges with other RaaS members and admins, claiming they haven’t been paid in time or that their share wasn’t proportionate to the amount of work they put in.
In 2022, expect more self-reliant cybercrime groups to rise and shift the balance of power within the RaaS eco-climate from those who control the ransomware to those who control the victim’s networks.
The Ransomware-as-a-Service eco system has evolved with the use of affiliates, the middlemen and women that work with the developers for a share of the profits. While this structure was honed during the growth of GandCrab, we are witnessing potential chasms in what is becoming a not-so-perfect union.
Historically, the ransomware developers, held the cards, thanks to their ability to selectively determine the affiliates in their operations, even holding “job interviews” to establish technical expertise. Using CTB locker as an example, prominence was placed on affiliates generating sufficient installs via a botnet, exploit kits or stolen credentials. But affiliates recently taking on the role and displaying the ability to penetrate and compromise a complete network using a variety of malicious and non-malicious tools essentially changed the typical affiliate profile towards a highly skilled pen-tester/sysadmin.
The hierarchy of a conventional organized crime group often is described as a pyramid structure. Historically, La Cosa Nostra, drug cartels and outlaw motor gangs were organized in such a fashion. However, due to further professionalization and specialization of the logistics involved with committing crime, groups have evolved into more opportunistic network-based groups that will work together more fluidly, according to their current needs.
While criminals collaborating in the world of cybercrime isn’t new, a RaaS group’s hierarchy has been more rigid compared to other forms of cybercrime, due to the power imbalance between the group’s developers/admins and affiliates. But things are changing. RaaS admins and developers were prioritized as the top targets, but often neglected the affiliates who they perceived to be less-skilled. This, combined with the lack of disruptions in the RaaS ecosystem, created an atmosphere where those lesser-skilled affiliates could thrive and grow into very competent cybercriminals.
As more ransomware players have entered the market, we suspect that the most talented affiliates are now able to auction their services for a bigger part of the profits, and maybe demand a broader say in operations. For example, the introduction of Active Directory enumeration within DarkSide ransomware could be intended to remove the dependency on the technical expertise of affiliates. These shifts signal a potential migration back to the early days of ransomware, with less-skilled operators increasing in demand using the expertise encoded by the ransomware developers.
Will this work? Frankly, it will be challenging to replicate the technical expertise of a skilled penetration tester, and maybe – just maybe – the impact will not be as severe as recent cases.

Apache server version 2.4.50 (CVE-2021-42013)
Regardless of the origins, you’ve arrived at Advanced Threat Research team’s monthly bug digest – an overview of what we believe to be the most noteworthy vulnerabilities over the last month. We don’t rely on a single scoring system like CVSS to determine what you need to know about; this is all about qualitative and experience-based analysis, relying on over 100 years of combined industry experience within our team. We look at characteristics such as wormability, ubiquity of the target, likelihood of exploitation and impact. If you don’t agree with these picks, we encourage you to write a strongly worded letter to your local senator. In lieu of that, we present our top CVEs from the last month.
What is it?
2 CVES / 1 Vuln – It appears Apache struggled a bit with this latest critical vulnerability, where it took two tries to fix a basic path traversal bug, which was introduced while patching last month’s SSRF mod_proxy vulnerability. As path traversal bugs do, this allows unauthorized users to access files outside the expected document root on the web server. But wait, there’s more! This can lead to remote code execution provided mod-cgi is enabled on the server.
Who cares?
A quick Shodan scan told me there are at least 111,000 server admins that should care! With Apache being the second largest market share holder of implemented webservers, there is a good chance your organization is using it somewhere. It’s always important to consider both internal and external facing assets when looking at your exposure. Apache is even commonly used as an embedded webserver to other applications and should be reviewed for use in any installed 3rd party applications. Oh yeah – and if you overlook an instance you have installed somewhere, this IS currently being actively exploited in the wild – no pressure.
What can I do?
Oh! I know, use Microsoft IIS! If you’re not ready to completely abandon your webserver implementation, I suggest updating to Apache 2.4.51. Remember to avoid version 2.4.50 as it does not patch both vulnerabilities. If you have been an astute system admin and followed the Apache documentation using the default and pretty darn secure “require all denied” directive for all files outside the document root, kudos to you! Although patching is still highly recommended, you are not immediately vulnerable.
The Gold Standard
We recognize in some special cases patching is harder than compiling gcc from source, so McAfee Enterprise has you covered; we have been detecting path traversal attacks in our Network Security Platform (NSP) like it was going out of style since 1990 (and it was).
What is it?
Ain’t nothin’ free anymore! Except kernel module addresses on your Windows machines, thanks to Microsoft Windows CVE-2021-40449. This vulnerability is a use-after-free in the NtGdiResetDC function of the Win32k driver and can lead to attackers being able to locally elevate their privileges.
Who cares?
Are you currently reading this from a Microsoft Windows machine? Using Microsoft Server edition in your cloud? Local attacks are often given lower priority or downplayed. However, it is important to recognize that phishing attacks are still highly successfully as an initial point of entry, facilitating a need for privilege escalation bugs to obtain higher level access. So, unless you are a hardcore Linux and Mac-only shop, you may want to patch since this is actively being exploited by cybercriminals, according to our friends at Kaspersky.
What can I do?
That boring Microsoft patch Tuesday thing still works, or you could just use a superior operating system like FreeBSD.
The Gold Standard
Have you checked out the latest version of McAfee Enterprise ENS lately? Detecting exploitation and cybercriminal activity is sort of its thing, assuming you have grabbed the latest signatures.
What is it?
An integer overflow vulnerability in the iOS “IOMobileFrameBuffer” component can allow an application to execute arbitrary code with kernel privileges. This has additionally been confirmed to be accessible from the browser.
Who cares?
Since Apple still reportedly holds 53% market share of all smartphone users, statistically speaking your organization should care too. It only takes one bad apple to hack your entire network, and with reported active exploitation in the wild it might happen sooner than you think.
What can I do?
You should be sensing a common theme in this section – and, in this case, you actually can take action! Stop reading this, plug that mobile device into a power source, and install the latest version of Apple iOS.
The Gold Standard
Since you stopped reading and updated already, congrats!

The holidays are almost here! That means it’s time to start making your list and checking it twice. To help prepare you for this year’s holiday shopping spree, McAfee is providing you with the ultimate holiday shopping list for every Tech lover in your family. Here are the devices to keep on your radar this holiday shopping season and what you should use to protect them.
Know someone who enjoys vanquishing aliens, building virtual amusement parks, and online battle royale? There’s a good chance that you do, as online gaming traffic increased 30% from the first to the second quarter of 2020. For the gaming guru in your life, consider gifting them a top-of-the-line gaming laptop so, they don’t have to compromise portability for playability. If they prefer to play in the comfort of their own home, consider giving the gamer in your life a snazzy new gaming monitor. This will allow them to enjoy a crystal-clear resolution, rapid refresh rate, and size to bring their virtual world to life. And to truly immerse your gamer in a new realm, gift them a new gaming console so they can enjoy optimal speed and stellar game lineups.
When shopping for your gamer, consider how you can empower them to stay secure while they play. A security solution like McAfee Gamer Security not only delivers a faster, quieter, and safer experience, but it can also boost a rig’s performance. This antivirus software detects threats through the cloud and optimizes resources to minimize frame drops. Gamers can even customize which games to boost (or even add other apps they’d like to boost), which background services to pause, and more. This improves your gamer’s experience and also keeps them safe while they play.
Does your tech-savvy teen love to browse on the go? Or perhaps you have a college student who likes to bring their online studying and video streaming with them beyond the home. For the mobile mastermind in your family, gift them a new smartphone or tablet this holiday season. These devices will allow your loved ones to access all their favorite apps and surf the web anytime, anywhere.
With the World Wide Web constantly at their fingertips, enable your family members to surf the internet with confidence by employing the help of a safe browsing solution like McAfee WebAdvisor. This trusty companion, available for free and included in the McAfee Total Protection app for iOS and Android, helps keep users safe from threats like malware and phishing attempts. Web Advisor blocks malicious sites, scans downloads, and alerts the user if a known threat is detected. With comprehensive security on their side, your mobile user will be free to search, stream, and download on the go.
The number of smart households (households that contain connected technology and can interact with other IoT devices) in the U.S. is expected to grow to 77.05 million by 2025. That may not come as a surprise, since IoT devices have upped the convenience of tech users’ lives everywhere. Perhaps your spouse or parents love filling their home with the latest and greatest smart home gadgets. This holiday season, give them the gift of convenience with a smart TV, speaker, thermostat, kitchen appliances, a personal home assistant – the list of smart home devices goes on!
While these devices can provide greater efficiency to anyone’s life, it’s important to be aware of the potential risks that come with this level of interconnectivity. Many product designers treat security as an afterthought, rushing to get their smart devices to market and consequentially creating an easy access point for criminals to exploit. But fear not! A solution like McAfee Secure Home Platform can automatically secure connected devices through a router with McAfee protection. It can hide your IoT devices from hackers, giving you the confidence that you have a solid line of defense against online threats.
For the Fitness Fanatic
At the onset of the pandemic, people adjusted their workout routines to accommodate for gym closures and began to rely on other solutions to stay fit. In fact, many turned to IoT devices used for virtual fitness, including wearable fitness trackers and stationary machines equipped with digital interfaces. Sound like someone you know? Consider giving them a stylish new or upgraded smartwatch that allows them to track their daily step count, heart rate, and sleep patterns.
While these devices can be instrumental in tracking users’ activity levels, it’s important to remember that wearable gadgets collect valuable health and location data a criminal could exploit. To keep your fitness fanatic happy and healthy without sweating their security, encourage them to install software updates immediately.

We love our social media. From beefs between popstars and professional pundits, to an open channel to the best jobs in the industry.
But guess what?
The threat actors know this, and our appetite toward accepting connections from people we have never met are all part of our relentless pursuit of the next 1,000 followers.
A result of this has seen the targeting of executives with promises of job offers from specific threat groups; and why not? After all, it is the most efficient method to bypass traditional security controls and directly communicate with targets at companies that are of interest to threat groups. Equally, direct messages have been used by groups to take control over influencer accounts to promote messaging of their own.
While this approach is not new, it is nearly as ubiquitous as alternate channels. After all, it does demand a level of research to “hook” the target into interactions and establishing fake profiles are more work than simply finding an open relay somewhere on the internet. That being said, targeting individuals has proven a very successful channel, and we predict the use of this vector could grow not only through espionage groups, but other threat actors looking to infiltrate organizations for their own criminal gain.
Potential Impacts & Implications
The potential impacts and implications for an executive or company that had their social media channels targeted by threat actors are endless. We began to see some nation state groups using platforms like LinkedIn to target executives, more specifically targeting the defense and aerospace industry. For years we’ve been accepting connections on LinkedIn to expand our network and threat actors are using this to their advantage with job adverts. Threat actors will find the executive they want to target in the company they want to go after and develop profiles that look like legitimate recruiters. By getting an executive on the hook, they could potentially convince them to download a job spec that is malware. These types of espionage campaigns can be carried out by other social networks as well, including Twitter, Instagram, Reddit, etc.
Techniques & Tactics
In the past, fake social profiles were relatively easy to spot, however in the case of DPRK, the cybercriminals spent time to setting up a profile, get hooked up into the infosec scene, gain followers and connections through LinkedIn, making it more difficult than before to detect a fraudulent account. When threat actors weaponize social media, they use techniques and tactics you see in the legitimate world. They diligently do their research into what types of jobs would be of interest to you and share an offer that will require you to open a document and trick you to carry out some type of action that will have you download malicious content onto your device.
Who Can Regulate?
We live in a world where we are governed by rules, territories, and jurisdictions; to hold a threat actor accountable, we would need digital evidence. We need to use regulations for digital investigations, and the bad guys don’t. While in territories where there isn’t an extradition treaty, threat actors can continue their malicious behaviors without any consequences. Unfortunately, cybercrime has nonrepudiation and threat actors can deny all knowledge and get away with it.
Prevention
Cybercrime will always be an issue and we need to be more aware of what threat actors are doing and what they’re after. It’s important to understand the threat and what is happening. At McAfee Enterprise and FireEye we work to track malicious actors and integrate intelligence into our products and make content available for CISO, CEO etc. to know what to do and what to look for in the event they are targeted.

With a focus on strategic intelligence, our team is not only monitoring activity, but also investigating and monitoring open-source-intelligence from a diversity of sources to gain more insights into threat-activities around the globe – and these include an increase in the blending of cybercrime and nation-state operations.
In many cases, a start-up company is formed, and a web of front companies or existing “technology” companies are involved in operations that are directed and controlled by the countries’ intelligence ministries.
In May 2021 for example, the U.S. government charged four Chinese nationals who were working for state-owned front companies. The front-companies facilitated hackers to create malware, attack targets of interest to gain business intelligence, trade-secrets, and information about sensitive technologies.
Not only China but also other nations such as Russia, North Korea, and Iran have applied these tactics. Hire hackers for operations, do not ask questions about their other operations if they do not harm the interests of their own country.
Where in the past specific malware families were tied to nation-state groups, the blurring starts to happen when hackers are hired to write code and conduct these operations.
The initial breach with tactics and tools could be similar as “regular” cybercrime operations, however it is important to monitor what is happening next and act fast. With the predicted increase of blurring between cybercrime and nation-state actors in 2022, companies should audit their visibility and learn from tactics and operations conducted by actors targeting their sector.
Potential Impacts & Implications
With more tools at their disposal, nation state actors are reshaping the cyberthreat landscape leaving destruction and disrupted operations in their wake. There have been many accusations of “spying” which poses as a major threat to economic and national security. The main aim of these attacks is to obtain intellectual property or business intelligence. We are seeing nation states devoting a significant number of resources, time and energy toward achieving strategic cyber advantages, resulting in the implications of divulging national interests, intelligence-gathering capabilities, and military strength through espionage, disruption and theft.
Techniques & Tactics
In May 2021 incident where four Chinese nationals were charged in a global hacking campaign; the indictment stated the threat actors used a front company to hide the Chinese government’s role in the information theft. We anticipate nation states will continue to team up with cybercriminals and create front companies to hide involvement and gain access to private information, military tactics, trade secrets and more. Adversaries will leverage techniques like phishing, known vulnerabilities, malware, crimeware and more to attain their goal.
On the blending of cybercrime/nation-state; understanding the functionalities of malware becomes more important than ever. Let me give an example, when you get a Trickbot infection, a part of the code will steal credentials, they could be sold to a ransomware crew with a possible ransomware attack as result, a complete cybercrime operation. But what if the Trickbot infection was ordered by a Nation State, the credentials are used for a long time operation; started as a crime, ends as a long APT.
Who Can Regulate?
It’s important for governments to hold actors accountable for cyber incidents. Government entities and researchers can likely assist public and private sector organizations in navigating this new cyber landscape by developing standards and/or template processes to drive cyber defense and maintaining operational resiliency.
Prevention
A threat actor’s goal is to gain access to data they can sell, leverage for ransom, or gain critical knowledge so it is important to properly encrypt critical data, rendering it unusable to unauthorized users. You should also maintain regular, offline backups and have an incident response plan ready. Maintaining and testing offline backups can similarly mitigate the impact of destructive malware.
