Ransomware. Even the name sounds scary.
When you get down to it, ransomware is one of the nastiest attacks a hacker can wage. They target some of our most important and precious things—our files, our photos, and the information stored on our devices. Think about suddenly losing access to all of them and being forced to pay a ransom to get access back. Worse yet, paying the ransom is no guarantee the hacker will return them.
That’s what a ransomware attack does. Broadly speaking, it’s a type of malware that infects a network or a device and then typically encrypts the files, data, and apps stored on it, digitally scrambling them so the proper owners can’t access them. Only a digital key can unlock them—one that the hacker holds.
Nasty for sure, yet you can take several steps that can greatly reduce the risk of it happening to you. Our recently published Ransomware Security Guide breaks them down for you, and in this blog we’ll look at a few reasons why ransomware protection is so vital.
The short answer is pretty bad—to the tune of billions of dollars stolen from victims each year. Ransomware targets people and their families just as explained above. Yet it also targets large organizations, governments, and even companies that run critical stretches of energy infrastructure and the food supply chain. Accordingly, the ransom amounts for these victims climb into millions of dollars.
A few recent cases of large-scale ransomware attacks include:
Who’s behind such attacks? Given the scope and scale of them, it’s often organized hacking groups. Put simply, these are big heists. It demands expertise to pull them off, not to mention further expertise to transfer large sums of cryptocurrency in ways that cover the hackers’ tracks.
As for ransomware attacks on people and their families, the individual dollar amounts of an attack are far lower, typically in the hundreds of dollars. Again, the culprits behind them may be large hacking groups that cast a wider net for individual victims, where hundreds of successful attacks at hundreds of dollars each quickly add up. One example: a hacker group that posed as a government agency and as a major retailer, which mailed out thousands of USB drives infected with malware.
Other ransomware hackers who target people and families are far less sophisticated. Small-time hackers and hacking groups can find the tools they need to conduct such attacks by shopping on the dark web, where ransomware is available for sale or for lease as a service (Ransomware as a Service, or RaaS). In effect, near-amateur hackers can grab a ready-to-deploy attack right off the shelf.
Taken together, hackers will level a ransomware attack at practically anyone or any organization—making it everyone’s concern.
Hackers have several ways of getting ransomware onto one of your devices. Like any other type of malware, it can infect your device via a phishing link or a bogus attachment. It can also end up there by downloading apps from questionable app stores, with a stolen or hacked password, or through an outdated device or network router with poor security measures in place. And as mentioned above, infected storage devices provide another avenue.
Social engineering attacks enter the mix as well, where the hacker poses as someone the victim knows and gets the victim to either download malware or provide the hacker access to an otherwise password-protected device, app, or network.
And yes, ransomware can end up on smartphones as well.
While not a prevalent as other types of malware attacks, smartphone ransomware can encrypt files, photos, and the like on a smartphone, just as it can on computers and networks. Yet other forms of mobile ransomware don’t have to encrypt data to make the phone unusable. The “Lockerpin” ransomware that has struck some Android devices in the past would change the PIN number that locked the phone. Other forms of mobile ransomware paste a window over the phone’s apps, making them unusable without decrypting the ransomware.
Part of avoiding ransomware involves reducing human error—keeping a watchful eye open for those spammy links, malicious downloads, bogus emails, and basically keeping your apps and devices up to date so that they have the latest security measures in place. The remainder relies on a good dose of prevention.
Our Ransomware Security Guide provides a checklist for both.
It gets into the details of what ransomware looks like and how it works, followed by the straightforward things you can do to prevent it, along with the steps to take if the unfortunate ends up happening to you or someone you know.
Ransomware is one of the nastiest attacks going because it targets our files, photos, and information, things we don’t know where we’d be without. Yet it’s good to know you can indeed lower your risk with a few relatively simple steps. Once you have them in place, chances are a good feeling will come over you, the one that comes with knowing you’ve protected what’s precious and important to you.

Speaking to many CISOs, it’s clear that many security executives view zero trust as a journey that can be difficult to start, and one that even makes identifying successful outcomes a challenge. Simultaneously, the topic of security resilience has risen up the C-level agenda and is now another focus for security teams. So, are these complementary? Or will they present conflicting demands that will disrupt rather than assist the CISO in their role?
One of the most striking results coming from Cisco’s latest Security Outcomes Report is that organizations with a mature zero trust implementation – those with basic controls, constant validation and automated workflows – experience a 30% improvement in security resilience compared to those who have not started their zero trust journey. So, these two initiatives – implementing zero trust and working to achieve security resilience – appear to complement each other while supporting the CISO when a cyber black swan swims in.
Security resilience is the ability to withstand an incident and recover more strongly. In other words, ride out the storm and come back better. Meanwhile, zero trust is best known as a “never trust, always verify” principle. The idea is to check before you provide access, and authenticate identity based on a risk profile of assets and users. This starts to explain why the two are complementary.
The Security Outcomes Report summarizes the results of a survey of more than 4,700 security professionals. Among the insights that emerge are nine security resilience outcomes they consider most important. The top three outcomes for resilience are prevention, mitigation and adaptation. In other words, they prioritize first the ability to avoid an incident by having the right controls in place, then the ability to reduce and reverse the overall impact when an incident occurs, and then the ability to pivot rapidly without being bound by too rigid a set of systems. Zero trust will support these outcomes.
Preventing, or reducing the likelihood of a cybersecurity incident, is an obvious first step and no surprise as the most important outcome. Pursuing programs that identify users and monitor the health of devices is a crucial a preventative step. In fact, simply ensuring that multifactor authentication (MFA) is ubiquitous across the organization can bring an 11% improvement in security resilience.
When incidents occur, security teams will need a clear picture of the incident they are having to manage. This will help in them respond quickly, with a proactive determination of recovery requirements. Previous studies show that once a team achieves 80% coverage of critical systems, the ability to maintain continuity increases measurably. This knowledge will also help teams develop more focused incident response processes. A mature zero trust environment has also been found to almost double a team’s ability to streamline these processes when compared to a limited zero trust implementation.
When talking to CISOs about successful implementation programs, communication within the business emerges as a recurring theme. Security teams must inform and guide users through the phases of zero trust implementation, while emphasizing the benefits to them. When users are aware of their responsibility to keep the organization secure, they take a participatory role in an important aspect of the business. So, when an incident occurs, they can support the company’s response. This increases resilience. Research has shown that a mature program will more than double the effect of efforts to improve the security culture. Additionally, the same communication channels established to spread the word of zero trust now can be called upon when an incident requires immediate action.
Mature implementations have also been seen to help increase cost effectiveness and reduce unplanned work. This releases more resource to cope with the unexpected – another important driver of resilience surfaced in Volume 3 of the Security Outcomes Report. Having more efficient resources enables the security function to reallocate teams when needed. Reviewing and updating resource processes and procedures, along with all other important processes, is a vital part of any of any change initiative. Mature zero trust environments reflect this commitment continuous assessment and improvement.
Inherent in organizational resilience is the ability to adapt and innovate. The corporate landscape is littered with examples of those who failed to do those two things. A zero trust environment enables organizations to lower their risk of incidents while adapting their security posture to fit the ongoing changes of the business. Think of developing new partners, supporting new products remotely, securing a changing supply chain. The basic tenets of MFA – including continuous validation, segmentation and automation – sets a foundation that accommodates those changes without compromising security. The view that security makes change difficult is becoming obsolete. With zero trust and other keys to achieving security resilience, security now is a partner in business change. And for those CISOs who fear even starting this journey, understanding the benefits should help them take that first step.

It has a way of sneaking up on you. Credit theft and fraud.
Maybe it’s happened to you. Maybe it’s happened to a friend or family member. There’s a call from the bank, a notification in your financial app, or a charge on the statement that’s beyond explanation. Someone else has tapped into your funds. Or worse yet, someone stole your identity and took out a loan in your name. You find out only after it’s happened.
That’s the trick with credit theft and fraud. People typically discover it after the damage is done. Then they’re left picking up the pieces, which can cost both time and money. Not to mention a potential knock to their credit score.
However, you can help keep it from happening to you. Our recently published Credit Protection Security Guide breaks down several ways. Here we’ll get into a quick introduction on the topic and show how you can prevent against credit theft and fraud better than ever before.
It’s an unfortunate reality in the world we live in today. Credit theft and fraud are something we all need to look out for, particularly as we increasingly shop and conduct our finances online, potentially exposing that information to thieves. Some figures estimate that for nearly every $100 in purchases made with debit and credit cards worldwide, somewhere around 7 cents can be stolen or fraudulent. As you can imagine, that figure adds up quickly, to the tune of more than $28 billion globally each year.
The flipside is this: today we have plenty of tools that make protecting our credit far easier than they ever were before. Up until now, that called for a time-consuming and sometimes rather manual process. You had to check credit separately with the different bureaus, place locks and freezes the same way, scan each credit report closely for suspicious activity, and so forth.
Now, online protection software can take much of that work off your hands. Comprehensive protection like McAfee+ has plans that offer credit monitoring, identity monitoring, and even identity theft protection & restoration—all quickly spotting any changes, notifying you if your personal information pops up on the dark web, and providing $1 of coverage toward restoring your credit along with the help of a licensed recovery pro if the unexpected happens to you.
Another thing online protection can do for you removes your personal information from those “people finder” and data broker sites. Identity thieves lean on those sites because they contain valuable information that they can piece together to commit theft and fraud in someone else’s name. If you think about your identity as a big jigsaw puzzle, these sites contain valuable pieces that can help complete the picture—or just enough to take a crack at your credit.
In fact, personal information fuels a global data trading economy estimated at $200 billion U.S. dollars a year. Run by data brokers that keep hundreds and even thousands of data points on billions of people, these sites gather, analyze, buy, and sell this information to other companies as well as to advertisers. Likewise, these data brokers may sell this information to bad actors, such as hackers, spammers, and identity thieves who would twist this information for their own purposes. In short, data brokers don’t discriminate. They’ll sell personal information to anyone.
Getting your info removed from these sites can seem like a daunting task. (Where do I start, and just how many of these sites are out there?) Our Personal Data Cleanup can help by regularly scanning these high-risk data broker sites for you and info associated with you like your home address, date of birth, and names of relatives—along with other detailed information about you that could include marriage licenses, voter registration and motor vehicle records, even real estate records too. It identifies which sites are selling your data, and depending on your plan, automatically requests removal.
How things have changed. Even as thieves have gotten savvier in the digital age, so have we. Collectively, we have a growing arsenal of ways that we can keep on top of our credit and protect ourselves from credit theft and fraud.
Our Credit Protection Security Guide breaks it all down in detail. In it, you’ll learn more about how thieves work, ways you can secure your credit online and off, how to monitor and lock it down, plus protect your mobile wallets too. It’s thorough. Yet you’ll find how straightforward the solution is. A few changes in habits and a few extra protections at your side will go a long way toward prevention—helping you avoid that call, text, or notification that your credit has been compromised.
In all, you can take control of your credit and make sure you’re the only one putting it to good use.

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!

Oh, the scammers online are frightful, and the deals they offer seem delightful. No matter what you think you know, let it go, let it go, let it go (to the tune of 1945’s Let it Snow by Vaughn Monroe with the Norton Sisters).
‘Tis the season to find ourselves awash in good tidings and, well, consumerism. While it’s only partly tongue in cheek, we must be honest with ourselves. We spend a lot of money online. Often, we find ourselves leaving things to the last minute and hope that the delivery folks can make the magic happen and send us all the widgets and grapple grommets while we surf the Internet from the safety of our sofas with coffee in hand.
But, not every deal is what it appears to be. Scammers are always lurking in the void of the Internet waiting for a chance to fleece the unexpecting from their hard-earned money. This can manifest itself to the unsuspecting in many ways. There are shipping frauds, gift card giveaways and vishing (phone-based scams).
Scams tend to rely on generating a false sense of urgency. The shipping scam emails often show up in our inboxes as a warning about a missed or delayed package that will be sent back to the point of origin if we don’t answer quickly. Of course, this requires a payment to receive the fictitious package.
These types of shipping scam emails are quite effective this time of year when more often than naught many people have enough orders coming to their house to make a fort with the empty boxes.
The other kinds of attacks are the gift card scams and vishing. The first of which taps into the sense of excitement that a person might receive something for free. “Fill out this form with your credit card information for a chance to win a $200 gift card.” Sadly, this attack works well for older generations for which giveaways were more common and they aren’t as accustomed to spotting digital swindlers.
The last scam that we will tackle here is often labeled as vishing or voice phishing. This is a method whereby the attackers call a victim and attempt to convince their target that they need to do something which will lead to the exposure of financial information while pressuring the victim to think if they don’t act quickly that they will miss an opportunity for personal gain.
Unfortunately, the aforementioned scams really bring in a lot of return for the criminal element. In 2021, over 92,000 victims over the age of 60 reported losses of $1.7 billion. This represents a 74 percent increase in losses over losses reported in 2020.
One additional scam that plays on the heart strings is the romance scams. A lot of single people find themselves lonely during the holidays and can be manipulated into thinking that they’ve found a romantic match. But this can drain the bank accounts as well.
In 2021, the IC3 received reports from 7,658 victims who experienced over $432 million in losses to Confidence Fraud/Romance scams. This type of fraud accounts for the highest losses reported by victims over the age of 60.
All these attacks prey on people’s emotional responses. So, how do we prepare ourselves? We need to make knowledge a capability and arm ourselves with information that will help us avoid being taken advantage of by criminals.
Passwords are a significant exposure. They are the digital equivalent of a house key. A password will work for anyone that has access to it. We need to utilize technologies such as multi-factor authentication (MFA) on websites where it is possible to do so. So even if bad actors have our password, the victim still needs to approve the login.
If we don’t have the option to use MFA it would be an excellent idea to make use of a password manager. This is a way to safely store passwords and not fall into the trap of reusing passwords on multiple sites. Attackers bank on human nature and if we use the same credentials on multiple sites there is a high possibility that the criminals could gain access to other sites if they compromise just one.
I’m usually one to eschew the practice of New Year’s resolutions but I’ll make an exception. Keep a keen sense about yourselves whenever you receive an email or SMS that you were not expecting. If a deal is too good to be true then, well, it most likely is a scam. If you’re in doubt, try to look up the phone number, email address, person or “organization” offering the “deal.” More often than not, you’ll find lots of people reporting that it’s a scam.
Rather than being visited by the three ghosts of holiday scams, make sure you and your loved ones are prepared for a happy holiday and a prosperous New Year.

Your phone is likely a daily companion, giving you access to work emails, chats with friends, weather reports, and more — all in the palm of your hand. You can also use your phone for browsing online, looking up everything from your favorite recipes to your most-read media webpages.
While being able to browse whenever and wherever you want is convenient, you might prefer that your phone doesn’t save all your online searches. For example, if you frequently let other people use your phone, you may not want them to have access to a history of your Google searches. In this case, you can use private browsing or “incognito mode.”
This allows you to browse online without leaving any trace of your browsing activity on your mobile phone. Configuring your phone to use incognito mode can give you greater confidence while surfing online, as you’ll enjoy the peace of mind that comes with knowing your browser history isn’t recorded on your device.
This article explains what incognito mode is and how you can set it up on your mobile phone.
Incognito mode allows you to browse online without leaving certain data on the device you’re using. Also referred to as private browsing mode, it makes sure there’s no record of your search engine history, websites you visited, and even login details (and related passcodes) on that device.
As soon as you close the incognito web browser window, any cookies are erased and all these details disappear instead of being saved.
That said, if you leave an incognito browser window open on your phone — and then hand your phone to someone else — they’ll be able to see the activity. So, if you want to make the most of incognito mode, make sure to close the browser window after every surfing session.
Further, if you actively bookmark a page, it will be saved — even if you’re in incognito mode. Read on for some more caveats surrounding incognito mode and the extent of privacy it gives you.
It’s important to note that incognito mode or private browsing mode is a device-specific privacy measure. It makes sure that your search and web browsing history isn’t visible on the device itself.
However, your traffic and activity are both still visible to third parties beyond your device, such as your network admin, internet service provider (ISP), and the websites and search engines that you visit.
Viewing in private or incognito mode also won’t disguise your unique IP address from these parties. Incognito mode further doesn’t secure your device against cyberthreats like hackers.
That said, there are plenty of other tools you can use to safeguard your device against cybercriminals. For example, McAfee+ helps to secure your Wi-Fi connection, shield you from malicious websites or links, and detect malware.
You may already be familiar with incognito mode through your computer. For example, many people set up incognito mode through browsers like Mozilla Firefox, Google Chrome, Safari, Microsoft Edge, or Internet Explorer.
However, incognito mode isn’t just for computers — you can also use it on your phone’s web browsing apps.
The steps to setting up incognito mode are fairly straightforward. That said, it depends largely on which type of device you have.
Setting up private browsing or incognito mode for an Android isn’t the same as setting it up for iOS. Read on to learn how to go incognito whether you’ve got an Apple iPhone or an Android phone like Samsung.
The process for setting up incognito mode also varies based on the browser you’re using. Here’s how to set it up in the Google Chrome browser for your Android (note that the Google Chrome app is the default browser for most Android phones):
Remember, for Google Chrome’s incognito mode to do the trick, you need to close your browsing session after each use. If you leave the tab open and someone else uses your phone, they can see your activity.
For iPhones, the default browser is Safari. Here’s how to set up private browsing in Safari for your iPhone:
Again, remember to close your browser’s private tabs when you’re done surfing. This makes sure that cookies are deleted and the private session is safely hidden from your device’s history.
The above steps can help you set up incognito mode on your Apple or Android phone’s browser. However, you probably use your phone for much more than browsing.
You might have apps for watching videos, getting driving directions, listening to music, and more. And the tips above will only protect your privacy when using the phone’s browser — not apps.
That said, some apps offer their very own in-app incognito mode. Examples include YouTube, Google Maps, Spotify, and Instagram. Other apps simply offer the option of private sessions, requiring you to log in with a dedicated username and password if you’re going to use the app. These include Whatsapp, Dropbox, Amazon, PayPal, and Evernote.
Some of these apps can even be configured so they’re only unlockable with touch ID or face ID.
Browsing in incognito or private mode on your phone allows you to surf online without leaving any trace of your search history on that specific device. However, it doesn’t block third parties like your internet service provider or network administrator from seeing what websites you’ve visited. Only your phone is affected.
Incognito mode also doesn’t protect you against potential cyberthreats, like malware. To stay safe and browse with confidence, consider McAfee Mobile Security. It includes Wi-Fi privacy protection, browsing safeguards, shields against unauthorized third-party activities, and more — and it works for Android and iOS devices. Find out more.

Microsoft has released its final monthly batch of security updates for 2022, fixing more than four dozen security holes in its various Windows operating systems and related software. The most pressing patches include a zero-day in a Windows feature that tries to flag malicious files from the Web, a critical bug in PowerShell, and a dangerous flaw in Windows 11 systems that was detailed publicly prior to this week’s Patch Tuesday.
The security updates include patches for Azure, Microsoft Edge, Office, SharePoint Server, SysInternals, and the .NET framework. Six of the update bundles earned Microsoft’s most dire “critical” rating, meaning they fix vulnerabilities that malware or malcontents can use to remotely commandeer an unpatched Windows system — with little to no interaction on the part of the user.
The bug already seeing exploitation is CVE-2022-44698, which allows attackers to bypass the Windows SmartScreen security feature. The vulnerability allows attackers to craft documents that won’t get tagged with Microsoft’s “Mark of the Web,” despite being downloaded from untrusted sites.
“This means no Protected View for Microsoft Office documents, making it easier to get users to do sketchy things like execute malicious macros, said Greg Wiseman, product manager at security firm Rapid7. This is the second Mark of the Web flaw Microsoft has patched in as many months; both were first publicly detailed over the past two months on Twitter by security researcher Will Dormann.
Publicly disclosed (but not actively exploited for now) is CVE-2022-44710, which is an elevation of privilege flaw in the DirectX graphics component of Windows 11.
Another notable critical bug is CVE-2022-41076, a remote code execution flaw in PowerShell — a key component of Windows that makes it easier to automate system tasks and configurations.
Kevin Breen at Immersive Labs said while Microsoft doesn’t share much detail about CVE-2022-41076 apart from the designation ‘Exploitation More Likely,’ they also note that successful exploitation requires an attacker to take additional actions to prepare the target environment.
“What actions are required is not clear; however, we do know that exploitation requires an authenticated user level of access,” Breen said. “This combination suggests that the exploit requires a social engineering element, and would likely be seen in initial infections using attacks like MalDocs or LNK files.”
Speaking of malicious documents, Trend Micro’s Zero Day Initiative highlights CVE-2022-44713, a spoofing vulnerability in Outlook for Mac.
“We don’t often highlight spoofing bugs, but anytime you’re dealing with a spoofing bug in an e-mail client, you should take notice,” ZDI’s Dustin Childs wrote. “This vulnerability could allow an attacker to appear as a trusted user when they should not be. Now combine this with the SmartScreen Mark of the Web bypass and it’s not hard to come up with a scenario where you receive an e-mail that appears to be from your boss with an attachment entitled “Executive_Compensation.xlsx”. There aren’t many who wouldn’t open that file in that scenario.”
Microsoft also released guidance on reports that certain software drivers certified by Microsoft’s Windows Hardware Developer Program were being used maliciously in post-exploitation activity.
Three different companies reported evidence that malicious hackers were using these signed malicious driver files to lay the groundwork for ransomware deployment inside victim organizations. One of those companies, Sophos, published a blog post Tuesday detailing how the activity was tied to the Russian ransomware group Cuba, which has extorted an estimated $60 million from victims since 2019.
Of course, not all scary and pressing security threats are Microsoft-based. Also on Tuesday, Apple released a bevy of security updates to iOS, iPadOS, macOS, tvOS and Safari, including a patch for a newly discovered zero-day vulnerability that could lead to remote code execution.
Anyone responsible for maintaining Fortinet or Citrix remote access products probably needs to update, as both are dealing with active attacks on just-patched flaws.

Ransomware groups are constantly devising new methods for infecting victims and convincing them to pay up, but a couple of strategies tested recently seem especially devious. The first centers on targeting healthcare organizations that offer consultations over the Internet and sending them booby-trapped medical records for the “patient.” The other involves carefully editing email inboxes of public company executives to make it appear that some were involved in insider trading.
Alex Holden is founder of Hold Security, a Milwaukee-based cybersecurity firm. Holden’s team gained visibility into discussions among members of two different ransom groups: CLOP (a.k.a. “Cl0p” a.k.a. “TA505“), and a newer ransom group known as Venus.
Last month, the U.S. Department of Health and Human Services (HHS) warned that Venus ransomware attacks were targeting a number of U.S. healthcare organizations. First spotted in mid-August 2022, Venus is known for hacking into victims’ publicly-exposed Remote Desktop services to encrypt Windows devices.
Holden said the internal discussions among the Venus group members indicate this gang has no problem gaining access to victim organizations.
“The Venus group has problems getting paid,” Holden said. “They are targeting a lot of U.S. companies, but nobody wants to pay them.”
Which might explain why their latest scheme centers on trying to frame executives at public companies for insider trading charges. Venus indicated it recently had success with a method that involves carefully editing one or more email inbox files at a victim firm — to insert messages discussing plans to trade large volumes of the company’s stock based on non-public information.
“We imitate correspondence of the [CEO] with a certain insider who shares financial reports of his companies through which your victim allegedly trades in the stock market, which naturally is a criminal offense and — according to US federal laws [includes the possibility of up to] 20 years in prison,” one Venus member wrote to an underling.
“You need to create this file and inject into the machine(s) like this so that metadata would say that they were created on his computer,” they continued. “One of my clients did it, I don’t know how. In addition to pst, you need to decompose several files into different places, so that metadata says the files are native from a certain date and time rather than created yesterday on an unknown machine.”
Holden said it’s not easy to plant emails into an inbox, but it can be done with Microsoft Outlook .pst files, which the attackers may also have access to if they’d already compromised a victim network.
“It’s not going to be forensically solid, but that’s not what they care about,” he said. “It still has the potential to be a huge scandal — at least for a while — when a victim is being threatened with the publication or release of these records.”

Holden said the CLOP ransomware gang has a different problem of late: Not enough victims. The intercepted CLOP communication seen by KrebsOnSecurity shows the group bragged about twice having success infiltrating new victims in the healthcare industry by sending them infected files disguised as ultrasound images or other medical documents for a patient seeking a remote consultation.
The CLOP members said one tried-and-true method of infecting healthcare providers involved gathering healthcare insurance and payment data to use in submitting requests for a remote consultation on a patient who has cirrhosis of the liver.
“Basically, they’re counting on doctors or nurses reviewing the patient’s chart and scans just before the appointment,” Holden said. “They initially discussed going in with cardiovascular issues, but decided cirrhosis or fibrosis of the liver would be more likely to be diagnosable remotely from existing test results and scans.”
While CLOP as a money making collective is a fairly young organization, security experts say CLOP members hail from a group of Threat Actors (TA) known as “TA505,” which MITRE’s ATT&CK database says is a financially motivated cybercrime group that has been active since at least 2014. “This group is known for frequently changing malware and driving global trends in criminal malware distribution,” MITRE assessed.
In April, 2021, KrebsOnSecurity detailed how CLOP helped pioneer another innovation aimed at pushing more victims into paying an extortion demand: Emailing the ransomware victim’s customers and partners directly and warning that their data would be leaked to the dark web unless they can convince the victim firm to pay up.
Security firm Tripwire points out that the HHS advisory on Venus says multiple threat actor groups are likely distributing the Venus ransomware. Tripwire’s tips for all organizations on avoiding ransomware attacks include:
While the above tips are important and useful, one critical area of ransomware preparedness overlooked by too many organizations is the need to develop — and then periodically rehearse — a plan for how everyone in the organization should respond in the event of a ransomware or data ransom incident. Drilling this breach response plan is key because it helps expose weaknesses in those plans that could be exploited by the intruders.
As noted in last year’s story Don’t Wanna Pay Ransom Gangs? Test Your Backups, experts say the biggest reason ransomware targets and/or their insurance providers still pay when they already have reliable backups of their systems and data is that nobody at the victim organization bothered to test in advance how long this data restoration process might take.
“Suddenly the victim notices they have a couple of petabytes of data to restore over the Internet, and they realize that even with their fast connections it’s going to take three months to download all these backup files,” said Fabian Wosar, chief technology officer at Emsisoft. “A lot of IT teams never actually make even a back-of-the-napkin calculation of how long it would take them to restore from a data rate perspective.”
