Smartphones have become such an integral part of our lives that it’s hard to imagine a time when we didn’t have them. We carry so much of our lives on our devices, from our social media accounts and photos of our pets to our banking information and home addresses. Whether it be just for fun or for occupational purposes, so much of our time and attention is spent on our smartphones.
Because our mobile devices carry so much valuable information, it’s important that we stay educated on the latest cyber schemes so we can be prepared to combat them and keep our data safe. According to Bleeping Computer, researchers have developed a trojan proof of concept tool that fakes a shutdown or reboot of iPhones, preventing malware from being removed and allowing hackers to secretly snoop on microphones and cameras.
Let’s dive into the details of this technique.
Typically, when an iOS device is infected with malware, the solution is as simple as just restarting the device. However, with this new technique researchers are calling “NoReboot,” ridding a device of malware is not quite as simple.
“NoReboot” blocks the shutdown and reboot process from being carried out, preventing the device from actually restarting. Without a proper shutdown and reboot, a malware infection on an iOS device can continue to exist. Because the device appears to be shut off with a dark screen, muted notifications, and a lack of response, it is easy to assume that the device has shut down properly and the problem has been solved. However, the “NoReboot” technique has only simulated a reboot, allowing a hacker to access the device and its functions, such as its camera and microphone. If a hacker has access to these functions, they could record the user without their knowledge and potentially capture private information.
This attack is not one that Apple can fix, as it relies on human-level deception rather than exploiting flaws found on iOS. That’s why it’s important that we know how to use our devices safely and stay protected.
As previously mentioned, smartphone usage takes up a big chunk of our time and attention. Since we are so often on these devices, it is usually fairly easy to tell when something isn’t working quite like it is supposed to. While these things could very well just be technical issues, sometimes they are much more than that, such as malware being downloaded onto your smartphone.
Malware can eat up the system resources or conflict with other apps on your device, causing it to act oddly.
Some possible signs that your device has been hacked include:
A slower device, webpages taking way too long to load, or a battery that never keeps a charge are all things that can be attributed to a device reaching its retirement. However, these things may also be signs that malware has compromised your phone.
Malware running in the background of a device may burn extra computing power, causing your phone to feel hot and overheated. If your device is quick to heat up, it may be due to malicious activity.
If apps you haven’t downloaded suddenly appear on your screen, or if outgoing calls you don’t remember making pop up on your phone bill, that is a definite red flag and a potential sign that your device has been hacked.
Malware may also be the cause of odd or frequent pop-ups, as well as changes made to your home screen. If you are getting an influx of spammy ads or your app organization is suddenly out of order, there is a big possibility that your device has been hacked.
To avoid the hassle of having a hacked phone in the first place, here are some tips that may help.
Promptly updating your phone and apps is a primary way to keep your device safe. Updates often fix bugs and vulnerabilities that hackers rely on to download malware for their attacks.
Apple’s App Store and Google Play have protections in place to help ensure that apps being downloaded are safe. Third-party sites may not have those same protections or may even be purposely hosting malicious apps to scam users. Avoiding these sites altogether can prevent these apps from allowing hackers into your device.
Hackers may use public Wi-Fi to gain access to your device and the information you have inside of it. Using a VPN to ensure that your network is private and only you can access it is a great way to stay protected on the go.
Turning off your Wi-Fi and Bluetooth when you are not actively using them is a simple way to prevent skilled hackers from working their way into your devices.
Some hackers have been known to install malware into public charging stations and hack into devices while they are being charged. Investing in your own personal portable charging packs is an easy way to avoid this type of hack.
Encrypting your phone can protect your calls, messages, and information, while also protecting you from being hacked. iPhone users can check their encryption status by going into Touch ID & Passcode, scrolling to the bottom, and seeing if data protection is enabled.
Although researchers agree that you can never trust a device to be fully off, there are some techniques that can help you determine whether your device was rebooted correctly.2 If you do suspect that your phone was hacked or notice some suspicious activity, restart your device. To do this, press and hold the power button and either volume button until you are prompted to slide the button on the screen to power off. After the device shuts down and restarts, notice if you are prompted to enter your passcode to unlock the device. If not, this is an indicator that a fake reboot just occurred. If this happens, you can wait for the device to run out of battery, although researchers have not verified that this will completely remove the threat.
If you are worried that your device has been hacked, follow these steps:

Every year we can count on new technology to make our lives easier. Right? As beneficial and convenient as tech can be, it can also pose risks to our online safety and privacy—risks that we should be prepared to handle. Increasingly, we’re seeing governments around the world implementing stricter privacy laws. And even major players like Google are phasing out invasive tracking technology like cookies. However, when it comes to activities like banking, shopping, taxes, and more, the need for broader online privacy protection has never been greater. Let’s take a look at some prominent trends in the way we now live online and how we can protect our data.
Crypto, the blockchain, NFTs, tokens – all of these terms are considered part of what’s being termed Web3. Whereas Web 2.0 described an internet made up of large corporations hosting content and consumers, Web3 is governed by the blockchain. What this means is that applications use a decentralized online ledger to document transactions of all sorts. The most famous example is bitcoin, a blockchain that acts as a digital currency. Another example would be NFTs, which are digital works of art. Web3 may be in its infancy, but it’s important to consider what this means for privacy and data protection. Blockchain affords users anonymity in regards to currencies like bitcoin. Of course that means bitcoin also has a reputation as the currency of choice for money-launderers and other shady enterprises. Still, that means it’s good for privacy, right? Well, maybe. The EU’s GDPR rights to erase or amend data are at odds with transactions on a blockchain, which are essentially unchangeable. So if you’re buying cryptocurrency, NFTs, or interacting with blockchains in other ways, just understand your personal information might be hidden, but the record of your transactions is totally visible.
Tip: If you’re keeping cryptocurrencies in an online wallet, you’ll want to use an identity protection service to monitor those account credentials so you can be warned of breaches and leaks onto the dark web.
Student privacy is a top concern as households turn to remote learning. In a rush to optimize remote learning experiences in the face of a rapidly evolving digital landscape, many educators and remote learners may not realize the hazards that put student privacy at risk.
Since 2020, schools have adopted a range of technologies to optimize the digital classroom, including virtual learning platforms, holistic learning solutions, and even social media applications. However, many of these digital platforms are not designed for child usage, nor do they have privacy policies in place to ensure that the student data gathered is protected. Many learning platforms may even treat student data as consumer data, raising more red flags regarding student data privacy and compliance. Online learning has also garnered the attention of cybercriminals looking to exploit student data, resulting in online bullying, identity theft, and more.
For educators and parents alike, knowledge is the greatest asset to mitigating the risks of remote learning. IT teams and educators must understand the implications of the student data they collect, govern access to it, and control its usage to comply with child privacy regulations. Parents can take proper precautions by discussing the importance of privacy with their children. Keeping learning platforms up to date and monitoring their children to prevent them from downloading suspicious apps or straying to unknown websites are all ways to ensure safer remote learning environments.
Tip: Getting a VPN for the family to use is a great way to safeguard your privacy while your kids are learning online.
Remote work has become commonplace nowadays as more companies permit their employees to work from home long-term and, for some, permanently. In a recent Fenwick poll among HR, privacy, and security professionals across industries, approximately 90% of employees now handle intellectual property, confidential, and personal information in their homes. Endpoint security, or the protection of end-user devices such as our laptops and mobile devices, poses more of a concern as employees trade in office networks for their in-home Wi-Fi. If these devices and networks are unsecured or if the data is not encrypted, employees run the risk of exposing sensitive information to hackers. Those of us working from home can help ensure the safety of our company’s confidential information by boosting our awareness of security threats and prevention measures via company-mandated security training.
Tip: McAfee’s Protection Score is a great way to understand how protected you are online and what you can do to stay more secure
This buzzy term is being used to describe Meta’s (previously Facebook) vision for a fully connected future. Right now it exists as an AR/VR space accessible through Meta’s own VR hardware, Oculus. However, the terminology has caught on as a catch-all for platforms that may contain work, business, gaming, entertainment, social interactions, and more in one easily navigable, immersive online setting. Web3 features, like blockchain, NFTs, and cryptocurrencies are being touted as integral parts of the metaverse. As exciting and futuristic as this is, there are major privacy questions that will have to be answered. This means that as customers you’ll want to think hard about what you choose to share through the metaverse and look into the privacy settings a platform offers you.
Tip: Use comprehensive online protection. McAfee Total Protection secures all aspects of your life online. From identity to online connections to antivirus, a full security suite like Total Protection keeps you and your family safer on all the devices you use and places you go online.
Some of the platforms I use the most allow me to keep track of and manage my finances. Whether it’s my mobile banking app or taking advantage of online tax filing, there is such a convenience in having the ability to pay bills, deposit checks, and more, all with the devices I use every day. But many of us may not realize just how much trust we put into these platforms to protect our online privacy, especially when we don’t have a clear picture of who exactly is on the other end of our online transactions.
While recognizing the signs of online banking and tax-related fraud helps ease the burdens associated with these schemes, there are multiple steps users can take to prevent becoming a victim of these scams in the first place.
Tip: Full-featured identity protection will protect you financially. Services like McAfee Identity Protection Service include credit checks, identity theft restoration, and even stolen fund restoration as benefits.
Digital devices are part of how we live our lives every day, whether we’re taking conference calls on our laptops, tracking the latest mile on our smartwatches, or banking on the go. Although our everyday digital devices make our lives that much more convenient, securing them makes our lives that much safer by minimizing online threats to ourselves and those around us. Safeguarding the digital platforms we use for work, school, finances, you name it, is the first step to ensuring our private information remains just that—private.

It’s a long-standing question. Can Apple Macs get viruses?
While Apple does go to great lengths to keep all its devices safe, this doesn’t mean your Mac is immune to all computer viruses. So what does Apple provide in terms of antivirus protection? Let’s take a look along with some signs that your Mac may be hacked and how you can protect yourself from further threats beyond viruses, like identity theft.
Whether hackers physically sneak it onto your device or by tricking you into installing it via a phony app, a sketchy website, or a phishing attack, viruses and malware can create problems for you in a few ways:
Some possible signs of hacking software on your Mac include:
Is your device operating more slowly, are web pages and apps harder to load, or does your battery never seem to keep a charge? These are all signs that you could have malware running in the background, zapping your device’s resources.
Like the performance issues above, malware or mining apps running in the background can burn extra computing power (and data). Aside from sapping performance, malware and mining apps can cause your computer to run hot or even overheat.
If you find apps you haven’t downloaded, along with messages and emails that you didn’t send, that’s a red flag. A hacker may have hijacked your computer to send messages or to spread malware to your contacts. Similarly, if you see spikes in your data usage, that could be a sign of a hack as well.
Malware can also be behind spammy pop-ups, changes to your home screen, or bookmarks to suspicious websites. In fact, if you see any configuration changes you didn’t personally make, this is another big clue that your computer may have been hacked.
Macs contain several built-in features that help protect them from viruses:
Similarly, all apps that wish to be sold on the Apple App Store must go through Apple’s App Review. While not strictly a review for malware, security matters are considered in the process. Per Apple, “We review all apps and app updates submitted to the App Store in an effort to determine whether they are reliable, perform as expected, respect user privacy, and are free of objectionable content.”
There are a couple reasons why Mac users may want to consider additional protection in addition to the antivirus protection that Mac provides out of the box:
In all, Macs are like any other connected device. They’re susceptible to threats and vulnerabilities as well. Looking more broadly, there’s the wider world of threats on the internet, such as phishing attacks, malicious links and downloads, prying eyes on public Wi-Fi, data breaches, identity theft, and so on. It’s for this reason Mac users may think about bolstering their defenses further with online protection software.
Staying safer online follows a simple recipe:
Reading between the lines, that recipe can take a bit of work. However, comprehensive online protection can take care of it for you. In particular, McAfee Total Protection includes an exclusive Protection Score, which checks to see how safe you are online, identifies gaps, and then offers personalized guidance, and helping you know exactly how safe you are.
An important part of this score is privacy and security, which is backed by a VPN that turns on automatically when you’re on an unsecure network and personal information monitoring to help protect you from identity theft—good examples that illustrate how staying safe online requires more than just antivirus.
So, Macs can get viruses and are subject to threats just like any other computer. While Macs have strong protections built into them, they may not offer the full breadth of protection you want, particularly in terms of online identity theft and the ability to protect you from the latest malware threats. Consider the threats you want to keep clear of and then take a look at your options that’ll help keep you safe.

When an outage affects a component of the internet infrastructure, there can often be downstream ripple effects affecting other components or services, either directly or indirectly. We would like to share our observations of this impact in the case of two recent such outages, measured at various levels of the DNS hierarchy, and discuss the resultant increase in query volume due to the behavior of recursive resolvers.
During the beginning of October 2021, the internet saw two significant outages, affecting Facebook’s services and the .club top level domain, both of which did not properly resolve for a period of time. Throughout these outages, Verisign and other DNS operators reported significant increases in query volume. We provided consistent responses throughout, with the correct delegation data pointing to the correct nameservers.
While these higher query rates do not impact Verisign’s ability to respond, they raise a broader operational question – whether the repeated nature of these queries, indicative of a lack of negative caching, might potentially be mistaken for a denial-of-service attack.
On Oct. 4, 2021, Facebook experienced a widespread outage, lasting nearly six hours. During this time most of its systems were unreachable, including those that provide Facebook’s DNS service. The outage impacted facebook.com, instagram.com, whatsapp.net and other domain names.
Under normal conditions, the .com and .net authoritative name servers answer about 7,000 queries per second in total for the three domain names previously mentioned. During this particular outage, however, query rates for these domain names reached upwards of 900,000 queries per second (an increase of more than 100x), as shown in Figure 1 below.
Figure 1: Rate of DNS queries for Facebook’s domain names during the 10/4/21 outage.
During this outage, recursive name servers received no response from Facebook’s name servers – instead, those queries timed out. In situations such as this, recursive name servers generally return a SERVFAIL or “server failure” response, presented to end users as a “this site can’t be reached” error.
Figure 1 shows an increasing query rate over the duration of the outage. Facebook uses relatively low Time-to-Lives (TTLs), a setting that tells DNS resolvers how long to cache an answer on their DNS records before issuing a new query, of from one to five minutes. This in turn means that, five minutes into the outage, all relevant records would have expired from all recursive resolver caches – or at least from those that honor the publisher’s TTLs. It is not immediately clear why the query rate continues to climb throughout the outage, nor whether it would eventually have plateaued had the outage continued.
To get a sense of where the traffic comes from, we group query sources by their autonomous system number. The top five autonomous systems, along with all others grouped together, are shown in Figure 2.
Figure 2: Rate of DNS queries for Facebook’s domain names grouped by source autonomous system.
From Figure 2 we can see that, at their peak, queries for these domain names to Verisign’s .com and .net authoritative name servers from the most active recursive resolvers – those of Google and Cloudflare – increased around 7,000x and 2,000x respectively over their average non-outage rates.
On Oct. 7th, 2021, three days after Facebook’s outage, the .club and .hsbc TLDs also experienced a three-hour outage. In this case, the relevant authoritative servers remained reachable, but responded with SERVFAIL messages. The effect on recursive resolvers was essentially the same: Since they did not receive useful data, they repeatedly retried their queries to the parent zone. During the incident, the Verisign-operated A-root and J-root servers observed an increase in queries for .club domain names of 45x, from 80 queries per second before, to 3,700 queries per second during the outage.
Figure 3: Rate of DNS queries to A and J root servers during the 10/7/2021 .club outage.
Similar to the previous example, this outage also demonstrated an increasing trend in query rate during the duration of the outage. In this case, it might be explained by the fact that the records for .club’s delegation in the root zone use two-day TTLs. However, the theoretical analysis is complicated by the fact that authoritative name server records in child zones use longer TTLs (six days), while authoritative name server address records use shorter TTLs (10 minutes). Here we do not observe a significant amount of query traffic from Google sources; instead, the increased query volume is largely attributable to the long tail of recursive resolvers in “All Others.”
Figure 4: Rate of DNS queries for .club and .hsbc, grouped by source autonomous system.
Earlier this year Verisign implemented a botnet sinkhole and analyzed the received traffic. This botnet utilizes more than 1,500 second-level domain names, likely for command and control. We observed queries from approximately 50,000 clients every day. As an experiment, we configured our sinkhole name servers to return SERVFAIL and REFUSED responses for two of the botnet domain names.
When configured to return a valid answer, each domain name’s query rate peaks at about 50 queries per second. However, when configured to return SERVFAIL, the query rate for a single domain name increases to 60,000 per second, as shown in Figure 5. Further, the query rate for the botnet domain name also increases at the TLD and root name servers, even though those services are functioning normally and data relevant to the botnet domain name has not changed – just as with the two outages described above. Figure 6 shows data from the same experiment (although for a different date), colored by the source autonomous system. Here, we can see that approximately half of the increased query traffic is generated by one organization’s recursive resolvers.
Figure 5: Query rates to name servers for one domain name experimentally configured to return SERVFAIL.
Figure 6: Query rates to botnet sinkhole name servers, grouped by autonomous system, when one domain name is experimentally configured to return SERVFAIL.
These two outages and one experiment all demonstrate that recursive name servers can become unnecessarily aggressive when responses to queries are not received due to connectivity issues, timeouts, or misconfigurations.
In each of these three cases, we observe significant query rate increases from recursive resolvers across the internet – with particular contributors, such as Google Public DNS and Cloudflare’s resolver, identified on each occasion.
Often in cases like this we turn to internet standards for guidance. RFC 2308 is a 1998 Standards Track specification that describes negative caching of DNS queries. The RFC covers name errors (e.g., NXDOMAIN), no data, server failures, and timeouts. Unfortunately, it states that negative caching for server failures and timeouts is optional. We have submitted an Internet-Draft that proposes updating RFC 2308 to require negative caching for DNS resolution failures.
We believe it is important for the security, stability and resiliency of the internet’s DNS infrastructure that the implementers of recursive resolvers and public DNS services carefully consider how their systems behave in circumstances where none of a domain name’s authoritative name servers are providing responses, yet the parent zones are providing proper referrals. We feel it is difficult to rationalize the patterns that we are currently observing, such as hundreds of queries per second from individual recursive resolver sources. The global DNS would be better served by more appropriate rate limiting, and algorithms such as exponential backoff, to address these types of cases we’ve highlighted here. Verisign remains committed to leading and contributing to the continued security, stability and resiliency of the DNS for all global internet users.

Most parents may find it difficult to relate to today’s form of cyberbullying. That’s because, for many of us, bullying might have come in a series of isolated, fleeting moments such as an overheard rumor, a nasty note passed in class, or a few brief hallway confrontations.
Fast forward a few dozen decades, and the picture is spectacularly different and a world few adults today would eagerly step into.
Cyberbullying includes targeting that is non-stop. It’s delivered digitally in an environment that is often anonymous. It’s a far-reaching, esteem-shattering, emotional assault. And the most traumatic component? The perpetual nature of the internet adds the ever-present threat of unlimited accessibility—kids know bullying can happen to anyone, at any time, and spread like wildfire.
The nature of cyberbullying can make a young victim feel hopeless and powerless. Skipping school doesn’t stop it. Summer vacation doesn’t diminish it. That’s because the internet is ever-present.
According to a 2020 Ditch the Label Cyberbullying Study, youth today reveal that carrying the emotional weight of being “connected all the time” is anything but fun and games. Here’s a snapshot.
While all kids are at risk for cyberbullying, studies reveal that some are more vulnerable than others.
According to the Pew Research Center, females experience more cyberbullying than their male counterparts; 38% of girls compared to 26% of boys. Those most likely to receive a threatening or aggressive text, IM, or email: Girls ages 15-17.
More data from the CDC and American University reveals that more than 28.1 % of LGBTQ teens were cyberbullied in 2019, compared to 14.1% of their heterosexual peers. In addition, Black LGTBQ youth are more likely to face mental health issues linked to cyberbullying and other forms of bullying as compared to non-Black LGTBQ and heterosexual youth.
Another community that can experience high cyberbullying is gamers. If your child spends a lot of time playing online games, consider paying close attention to the tone of conversations, the language used, your child’s demeanor during and after gaming, and, as always, stay aware of the risks. In a competitive gaming environment that often includes a variety of age groups, cyberbullying can quickly get out of control.
Lastly, the reality no parent wants to confront—but one that is critical to the conversation—is that cyberbullying and suicide may be linked in some ways. According to JAMA Pediatrics, approximately 80% of young people who commit suicide have depressive thoughts, and in today’s online environment, cyberbullying often leads to more suicidal thoughts than traditional bullying.
Each new year represents 365 new days and 365 new chances to do things a little bit better than we’ve done them in the past. And while it’s impossible to stop our kids from wandering into the crossfire of hurtful words online, we can do everything possible to reduce their vulnerability and protect their self-esteem.

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.

The internet’s greatest feat? Fundamentally shifting how we live. Once a revelation, it quickly set our long-standing beliefs about how we work, play, and connect into a whole new context.
Today, the shifts come fast. Video meetings once felt alien. Now, they’re part of our routine. We’ve gone from setting doctor’s appointments online to actually seeing the doctor online—and from family visits to seeing everyone in seconds on a screen.
At McAfee, we’ve seen our share of shifts as well. Looking back across our thirty-plus years, we were among the first to deliver antivirus technology. First to create a biometric password manager. First to give people an intuitive Protection Score, and so much more. And we’re not stopping. We’re protecting people and their ever-changing lives. That means covering all your life online, from security to privacy to identity, in a way that adds to your confidence and enjoyment too.
Confidence and enjoyment. Those two words mark our next shift in online protection. We’re bringing those feelings to life across the McAfee experience. And it’ll redefine the way you stay safe online.
Safety has an unmistakable feeling. As we bring that feeling to online protection, you’ll see a remarkable evolution. It will look and act in bold new ways, guide you, reassure you, and most importantly, keep you safe. In all, it’s a new breed of online protection that’s helpful, even thoughtful, in the ways it looks out for you.
And this evolution is already underway. You’ll find that feeling in everyday moments as we make them simpler, freer, and safer—such as paying your bills at a coffee shop, managing your family’s healthcare from your laptop, and booking flights to catch up with old friends. Across them all, our protection will have your back, and even offer guidance when needed, all while you do you—wherever your day takes you and no matter what “online” looks like next.
There’s simply so much to see out there. And with us by your side, you’ll feel safe and stay that way. Life online will continue to surprise us. In the best of ways. And people have a right to enjoy every moment of it, confident that they’re safe and secure, in ways they can point to and feel.
That’s our next big shift. Giving you the unmistakable feeling of safety. You deserve it. More than that, it’s your right. And we’re proud to bring it to you.

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.

The internet is meant for all to enjoy. And that’s who we’re looking out for—you and everyone who wants to enjoy life online.
We believe it’s important that someone has your back like that, particularly where some of today’s hacks and attacks can leave people feeling a little uneasy from time to time. You’ve probably seen stories about data breaches at big companies pop up in your news feed. Or perhaps you or someone you know had their debit or credit card number hacked. Problems like these are out there, unfortunate thorns in the side of the internet we’ve come to love. Yet while these issues persist, there’s plenty you can do to avoid them.
That’s where we have your back—doing all we can to make life online enjoyable for everyone, with protection that helps people finally feel safe and stay that way.
The reality is that nobody wants to deal with hackers, malware, and other attacks crop up on the internet. And while it’s important to be aware of those things, we’d rather that you didn’t have to worry about them. Protection should come easy. Whether it’s keeping your banking, shopping, and streaming secure, along with your privacy and personal info too, protection should feel simple and tailored to you. That’s what we strive for.
So as you think about protecting your life online, take a moment to consider what you’re protecting. As you do, you’ll see that it means far more than protecting your computers, phones, and other devices. Ultimately, it’s about protecting you, and all the important things connected to you. You can think of it in three ways …
What’s among the top things people say they want to protect? Their photos. Not far behind photos are all manner of digital treasures that people like to keep close, which ranges anywhere from music they’ve downloaded to old voicemails of their children, nieces, and nephews that they’ve saved over the years. Without a doubt, we have plenty of things stored on our computers and phones that we simply couldn’t do without.
Protecting these things means protecting the devices you use to store and access them. Installing comprehensive online protection software like ours is the first step. In addition to award-winning antivirus software and firewall protection to help keep hackers at bay (and away from your photos and other precious files), it goes a step further.
Our new Online Protection Score shows you just how safe you are and guides you through simple steps that can seal up gaps and improve your protection overall. In all, it’s a personalized and simple way to make sure you’re protected as possible and continually make improvements as they’re needed. It’s a way of getting expert protection without being an expert.
There’s also the “Important Stuff” in life, like our financial records, tax returns, and all the banking that we do on our phones and computers. And let’s throw shopping into mix because shopping’s important too! You can protect the important things like this, which can help hackers out of your business.
For starters, you can protect your important files three ways with our online protection by using a combination of the McAfee® File Lock and Shredder features to manage your privacy:
You can lock down your privacy even further with a VPN that can shield you automatically from snooping attacks online, whether at home or when using public Wi-Fi. It creates an encrypted connection that works like a private tunnel that hides your IP address and the things you’re doing online from cybercrooks. It’s ideal for keeping your sensitive personal information like your financial data, passwords, and browsing history hidden from both hackers and websites.
And here’s another big help. A password manager. You likely have dozens of passwords, plus a few more that you’ve probably forgotten about. You can protect your passwords and the accounts associated with them with a password manager that creates and securely stores a strong, unique password for each of your accounts. Plus, you can use it to update those passwords on the regular. Few things make it tougher for hackers than strong, unique passwords that get changed often. In a time of data breaches and account theft, a password manager is a great call.
While it’s important to focus on protecting things like laptops, phones, photos, files, and data, you’re ultimately protecting something far greater You. Your privacy, your personal information, your accounts, all the things that taken together make you—you. The thing is that our lives are more fluid and mobile than ever before. One moment we’re banking on our laptop, the next we’re splitting the cost of dinner with a payment on our phone. The constant here is you. You’re at the center of all this activity regardless of the device you’re using. The same goes for your family and the people you care about.
That’s why we protect people, not just their devices.
McAfee Identity Protection Service monitors the dark web for your personal info such as emails and associated passwords, up to 60 different types of critical info. If we detect that your data was stolen, you’ll get immediate alerts on the devices of your choice and guidance on how to secure your info quickly and effectively. In all, you can keep tabs on your identity any time you’re connected to the internet, and if an issue crops up you can click, solve, and carry on.
Extended identity protection offers up the extra comfort of knowing that you have licensed recovery pros on the case if identity theft does happen to you. This includes monitoring and restoration services, along with identity theft insurance for lawyer fees, travel expenses, lost wages, and more.
While that’s just a few of the ways McAfee has your back, we hope it gives you a good sense of what online protection should do—how it should protect you and all the things connected to you. And on today’s internet, that’s quite a bit. There’s so much to experience online today, and we believe you should enjoy all of it, freely and with the confidence that comes from knowing you’re safe.

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:
McAfee Advanced Threat Research: Log4Shell Vulnerability is the Coal in our Stocking for 2021
In this blog, we present an overview of how you can mitigate the risk of this vulnerability exploitation with McAfee Enterprise solutions. Due to the severity of this vulnerability and the observed exploitation attempts already taking place, the KB article linked below will be continually updated to communicate detailed actions to mitigate risk with McAfee Enterprise products.

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

Most of us take our skills for granted when it comes to technology. We move effortlessly between applications and multiple devices. We install new software, set up numerous accounts, and easily clear technical hurdles that come our way. Unfortunately, that picture isn’t the norm for many older adults.
Engaging with technology can be challenging for older adults. However, when digital literacy skills are neglected or avoided, everyday activities such as online bill paying, shopping, medical appointments, and even social media can be overwhelming. And, since the pandemic, the digital divide between older adults and digital skills has become even more evident.
One Pew study revealed that older adults continue to lag behind younger adults when it comes to technology adoption in that 41% do not use the internet at all, 23% do not use cell phones, and over 75% say they require help when learning how to use new technology.
The Pew study also highlighted good news: Attitudes shift for the better when older adults increase their digital skills and access the Internet more frequently. Fully 79% of older adults who use the internet regularly agree with the statement that “people without internet access are at a real disadvantage because of all the information they might be missing.” In comparison, 94% agree with the statement that “the internet makes it much easier to find information today than in the past.”
So how can we help the older adults in our lives grow both their digital skills and their confidence? Building practical digital skills begin with a commitment to one another, to consistency, and to learning. Here are some tips to get you started.
If you are helping an older adult build their digital skills, it’s crucial to schedule dedicated training time. Commitment and consistency will be key to achieving real results. If you’re the older adult learning on your own, set aside dedicated learning time with clear goals. For instance, “Each day this week from 7 a.m. to 9 a.m. I will learn how to set up my email and how to maximize security on all my devices.”
Fortunately, more and more resources are emerging to help older adults bridge their technology gaps, and most are free. A few places to begin include AARP’s Senior Planet, Candoo Tech, and GetSetUp. To find a program in your area, go to at3center.net.
Online security is one of the most critical conversations you can have with the older adults in your life. Following best practices such as installing security software, using strong passwords with Two-Factor Authentication (2FA), understanding data privacy, and knowing how to identify phishing and malware scams are fundamental components of digital literacy. For a deeper dive into cybersecurity best practices, read more.
Older adults can easily fall prey to scams, conspiracies, hoaxes, and false news stories online. A recent study out of Princeton and NYU found that, prior to the 2016 election, adults over 65 were seven times more likely than those under 29 to post articles from fake news domains. Understanding how to spot misinformation online is a critical skill for anyone online. One resource to build media literacy is MediaWise for Seniors, a series of free online courses by Poynter designed to help older adults detect and combat fake news and misinformation. In addition, consider dialogue on how to challenge each piece of digital content by asking:
Jargon excludes and when you use insider language with a non-technical person, it can get overwhelming. Slow down. Use ordinary terms. For instance, instead of the hyperlink, consider “link.” Instead of URL, opt for “website address.” Rather than DM/PM, use “Private Message.” Note: Avoiding jargon doesn’t mean you dumb down to a person; it means using plain language to explain the same concept.
It’s a myth (and an unfortunate stereotype) that older adults don’t have the ability or don’t want to learn about technology. Frankly, they can, and they do. However, physical and mental changes are part of the aging process, which means repetition and patience are part of the process. Consider creating easy-to-read cheat sheets to summarize the day’s lesson.
Technology is impacting our lives in myriad ways, and no one feels this reality pressing in more than older adults. If you find yourself in the privileged position of coaching an older adult toward digital confidence, remind them of the gains ahead and that the gap from “here” to “there” isn’t nearly as large as they’ve imagined. Whenever possible, point their sights to the proven benefits of stepping off the sidelines and into a connected world.

Did you just get word that your personal information may have been caught up in a data breach? If so, you can take steps to protect yourself from harm should your info get into the hands of a scammer or thief.
How does that information get collected in the first place? We share personal information with companies for multiple reasons simply by going about our day—to pay for takeout at our favorite restaurant, to check into a hotel, or to collect rewards at the local coffee shop. Of course, we use our credit and debit cards too, sometimes as part of an online account that tracks our purchase history.
In other words, we leave trails of data practically wherever we go these days, and that data is of high value to hackers. Thus, all those breaches we read about.
Whether it’s a major breach that exposes millions of records or one of many other smaller-scale breaches like the thousands that have struck healthcare providers, each one serves as a reminder that data breaches happen regularly and that we could find ourselves affected. Depending on the breach and the kind of information you’ve shared with the business or organization in question, information stolen in a breach could include:
What do crooks do with that data? Several things. Apart from using it themselves, they may sell that data to other criminals. Either way, this can lead to illicit use of credit and debit cards, draining of bank accounts, claiming tax refunds or medical expenses in the names of the victims, or, in extreme cases, assuming the identity of others altogether.
In all, data is a kind of currency in of itself because it has the potential to unlock several aspects of victim’s life, each with its own monetary value. It’s no wonder that big breaches like these have made the news over the years, with some of the notables including:
As mentioned, these are big breaches with big companies that we likely more than recognize. Yet smaller and mid-sized businesses are targets as well, with some 43% of data breaches involving companies of that size. Likewise, restaurants and retailers have seen their Point-of-Sale (POS) terminals compromised, right on down to neighborhood restaurants.
When a company experiences a data breach, customers need to realize that this could impact their online safety. If your favorite coffee shop’s customer database gets leaked, there’s a chance that your personal or financial information was exposed. However, this doesn’t mean that your online safety is doomed. If you think you were affected by a breach, you can take several steps to protect yourself from the potential side effects.
One of the most effective ways to determine whether someone is fraudulently using one or more of your accounts is to check your statements. If you see any charges that you did not make, report them to your bank or credit card company immediately. They have processes in place to handle fraud. While you’re with them, see if they offer alerts for strange purchases, transactions, or withdrawals.
Our credit monitoring service can help you keep an eye on this. It monitors changes to your credit score, report, and accounts with timely notifications and guidance so you can take action to tackle identity theft.
Breached and stolen information often ends up in dark web marketplaces where hackers, scammers, and thieves purchase it to commit yet more crime. Once it was difficult to know if your information was caught up in such marketplaces, yet now an identity monitoring service can do the detective work for you.
Our service monitors the dark web for your personal info, including email, government IDs, credit card and bank account info, and more. This can help keep your personal info safe with early alerts that show you if your data is found on the dark web, an average of 10 months ahead of similar services. From there, you’ll get guidance that you can act on, which can help protect your info and accounts from theft.
If you suspect that your data might have been compromised, place a fraud alert on your credit. This not only ensures that any new or recent requests undergo scrutiny, but also allows you to have extra copies of your credit report so you can check for suspicious activity. You can place one fraud alert with any of the three major credit reporting agencies (Equifax, Experian, TransUnion) and they will notify the other two. A fraud alert typically lasts for a year, although there are options for extending it as well.
Freezing your credit will make it highly difficult for criminals to take out loans or open new accounts in your name, as a freeze halts all requests to pull your credit—even legitimate ones. In this way, it’s a far stronger measure than placing a fraud alert. Note that if you plan to take out a loan, open a new credit card, or other activity that will prompt a credit report, you’ll need to take extra steps to see that through while the freeze is in place. (The organization you’re working with can assist with the specifics.) Unlike the fraud alert, you’ll need to contact each major credit reporting agency to put one in place. Also, a freeze lasts as long as you have it in place. You’ll have to remove it yourself, again with each agency.
You can centrally manage this process with our security freeze service, which stops companies from looking at your credit profile, and thus halts the application process for loans, credit cards, utilities, new bank accounts, and more. A security freeze won’t affect your credit score.
Ensure that your passwords are strong and unique. Many people utilize the same password or variations of it across all their accounts. Therefore, be sure to diversify your passcodes to ensure hackers cannot obtain access to all your accounts at once, should one password be compromised. You can also employ a password manager to keep track of your credentials, such as the one you’ll find in comprehensive online protection software.
If the unfortunate happens to you, an identity theft coverage & restoration service can help you get back on your feet. Ours offers $1 million in coverage for lawyer fees, travel expenses, and stolen funds reimbursement. It further provides support from a licensed recovery expert who can take the needed steps to repair your identity and credit. In all, it helps you recover the costs of identity theft along with the time and money it takes to recover from it.
You can take this step any time, even if you haven’t been caught up in a data breach. The fact is that data broker companies collect and sell thousands of pieces of information on millions and millions of people worldwide, part of a global economy estimated at $200 billion U.S. dollars a year. And they’ll sell it to anyone—from advertisers for their campaigns, to scammers who will use it for spammy emails, texts, and calls, and to thieves who use that information for identity theft.
Yet you can clean it up. 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, even manage the removal for you.
Comprehensive online protection software will offer you the tools and services listed above, along with further features that can protect you online. That includes a VPN to keep your time online more private from online data collection while protecting it from thieves who’re out to steal credit card and account information. It also includes web browsing protection that can warn you of sketchy websites and malicious downloads that look to steal your information. In all, it’s thorough protection for your devices, privacy, and identity. And in a time of data breaches, that kind of protection has become essential.
The post How to Protect Yourself From Identity Theft After a Data Breach appeared first on McAfee Blog.

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.

Protecting your devices with antivirus is a great start, yet it’s only one part of staying safer online. With the way scammers and thieves target people today, you need to protect yourself too—specifically your identity and privacy.
Threats have evolved over the years. While hackers still wage malware attacks on computers, tablets, and smartphones, the devices aren’t the ultimate target. You are. The personal and private information created and kept on your devices have tremendous value because scammers and thieves can use it to steal your identity, open credit cards in your name, and commit all kinds of identity theft and fraud.
Yet just as using antivirus protection can keep you safer online, using privacy and identity protection will keep you far safer still. Let’s look at how all three can work in concert.
Privacy protection focuses on keeping your information from getting into the hands of advertisers, cybercriminals, and data brokers who want to use it for their benefit. To boost your online privacy, consider a few thoughtful additions to your daily browsing, email, and social media routine.
First, think carefully about your social media habits. Do you post everything about your day and childhood, pin your location, and share photos of documents that include your full name, birthday, or address? You may want to consider cutting back on what you broadcast on the internet, especially if your account is public for anyone to view.
Unfortunately, while your friends and family may love your status updates, cybercriminals love them more. After only minutes of snooping, cybercriminals can glean enough personal details about you to impersonate you or target a social engineering attempt at you. To keep your private information more private, limit what you share on social media, pare down your follower and friend lists to only the closest people, and if your social media account platform supports it set your account to private.
One more way to protect your privacy is to use a virtual private network (VPN). A VPN allows you to remain far more anonymous online by shielding your location and device information, along with the data passing along your connection—which includes things like your passwords, account information, and other sensitive info.
A VPN offers further protection when you’re logged on to a public network, like those in coffee shops, libraries, and transportation hubs. Cybercriminals often lurk on non-password-protected Wi-Fi networks and eavesdrop on people paying bills or online shopping to steal their credentials.
However, criminals aren’t the only ones who intrude on your privacy. Online data brokers collect thousands of data points on millions of people, then post bits of that information for anyone to see and offer far more detailed information for a price.
Who buys this information? More legitimate purposes include people conducting background checks, journalists, law enforcement, and, largely, advertisers. With such in-depth information, advertisers can target highly specific audiences with their ads, all based on personal information that can include shopping habits from customer loyalty cards, health data from fitness apps, and information scraped from public social media posts—just to name a few of the umpteen sources they draw from.
Yet data brokers won’t discriminate. They’ll sell to scammers and thieves as well, who can then use that personal information to help them commit identity fraud and theft.
However, you can do something about this. Personal data cleanup can scan some of the riskiest data broker sites and show you which ones are selling your personal info. It can also provide guidance on how you can remove your data from those sites and can even manage the removal for you. And because data brokers continually update their data, personal data cleanup will continue to monitor those sites and help you get your information removed should it crop up again.
In all, if you feel that your privacy shouldn’t be up for grabs, a personal data cleanup service can
Another form of protection focuses on keeping you safer from identity theft and fraud. Here, thieves will steal personal and account information to rack up charges on existing credit and debit cards, open entirely new accounts and lines of credit, or impersonating the victim themselves for employment, health insurance coverage, or to commit other crimes in someone else’s name.
A few forms of identity crime include:
This list provides just a few examples, yet in all its forms, identity crime can affect your finances, credit score, and ability to secure loans, a mortgage, or future credit cards.
One way to keep your identity secure is to guard your PII carefully. Never give out your Social Security Number unless it’s necessary—such for employment, opening bank and credit accounts, applying for public assistance, filing tax returns, or obtaining a driver’s license. While other businesses may ask you for your Social Security Number for identification purposes, you are not legally bound to provide it. You can ask to provide an alternate form. Also, never share it over email or text where it can be potentially intercepted.
Beyond your Social Security Number, you can take steps to protect the many other forms of personal information you have. An identity monitoring service can keep tabs on everything from email addresses to IDs and phone numbers for signs of breaches so you can take action to secure your accounts before they’re used for identity theft. Likewise, credit monitoring can watch for unusual credit activity that could be an indicator of identity theft as well.
Should the unfortunate occur, identity theft & recovery coverage like ours can help you get back on track in several ways. First, it provides $1 million in identity theft coverage that covers travel expenses, legal fees, and stolen funds reimbursement. Additionally, it provides the assistance of a licensed identity theft recovery pro who can help you repair your identity and credit.
The third form of protection involves our devices, like computers, tablets, and phones—protecting them from both physical and digital threats.
The first step you can take is to use a password, PIN, facial recognition, or other form of lock to keep your devices safer in the event of loss or theft. With this protection, your device is effectively an open book, providing a thief with access to all manner of personal information, accounts, and apps.
Taking this protection a step further is learning to remotely locate your devices and then lock or wipe them. Many laptops and mobile devices offer location tracking services to help find a lost device—and yet others allow the owner to remotely lock or even wipe the contents of that device if they fear it’s lost for good or fallen into the wrong hands.
It’s all rather straightforward, and device manufacturers have put up helpful web pages that can walk you through the process:
Another good step you can take is to back up your files, whether with an online cloud service, a physical external drive, or both. By storing your files in the cloud, you can recover them quickly if your device is stolen and you have to remotely wipe its contents. Storing them on an external drive also lets you recover your files if your device is stolen, however, you’ll want to keep it in a secure location so that it can’t be stolen as well. Options include a fireproof safe where you keep other valuables or even a safe deposit box. The drawback is that you will have to back up files manually and regularly whereas cloud backup is practically automatic when you’re connected to the internet.
Another component of device security is defending against malicious software. Viruses and malware can make their way onto your devices through several avenues, including sketchy websites, dishonest downloads, phishing schemes, and clicking on ads. The challenge is that several of these avenues can look rather legitimate at first glance. Sophisticated hackers, scammers, and thieves have learned how to make their bogus websites and search results look like the real thing. One way you can prevent making a bad click or downloading an attachment loaded with malware is to use web advisor software that can protect you while you browse.
And finally, yes, antivirus is a must now just as it’s ever been. When kept up to date with the latest updates, it can prevent malware from getting onto your devices—plus scan, detect, and delete viruses and malware from your devices should they make their way onto them.
The threats out there are many, and they go beyond threats to your devices. Hackers, scammers, and thieves are quite interested in you. Your accounts, your personal information, and anything they can grab to commit theft or fraud. Protecting yourself today calls for not only protecting your devices but your privacy and identity too.
Comprehensive online protection software like ours covers all three—privacy, identity, and devices. It includes the protections mentioned above, plus dozens of features more such as ransomware coverage, credit freezes, security locks, and an online protection score that shows you just how safe you are, along with suggestions that can make you safer still.
In all, it gives you far more control over your privacy and personal information, control that should rest in your hands, and not in the hands of data brokers, hackers, scammers, and thieves.

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.
Several security researchers have recently reported a powerful software bug that could potentially affect thousands of popular websites, services, hosted apps, and even game servers—thanks to an apparent flaw that could allow hackers to compromise or take control of servers that run them.
Just as reported by the developers of the popular Minecraft game, this flaw potentially affects servers that run Twitter, Apple’s iCloud, the Steam gaming platform, and a growing number of others that may be vulnerable.
One research group has dubbed the vulnerability as “Log4Shell,” and the name appears to be sticking. It involves a widely used software used to log information on servers. This software is open source, meaning it is freely available to developers. As a result, countless organizations and businesses use it on their servers.
While details are still evolving, researchers are acting with a proper degree of caution given the potential scope of the issue. Needless to say, the immediate level of concern remains high given the potential of the flaw to impact millions of servers, devices, and the people who use them.
At this early stage, a few things appear to be possible:
The developers of Minecraft have provided several steps that detail what both players and server hosts should do to protect themselves. The developers clearly recognize the potential gravity of the situation and are taking a proactive approach in saying, “This vulnerability poses a potential risk of your computer being compromised, and while this exploit has been addressed with all versions of the game client patched, you still need to take [steps] to secure your game and your servers.” We’ve provided the link to those steps here:
Recommended steps for Minecraft players and server hosts.
Right now, as this situation evolves, the best step is to keep your eyes open. If the app, service, site, or game you’re on performs strangely, consider signing out and closing it down. Then, perform a security scan on your device to check for viruses, malware, or other threats. Follow the guidance from your online protection software if any results come up.
You may also consider limiting your app and service usage to the most important activities. If it’s not an urgent or important online task or activity, see about putting it off until more is known.
Likewise, stay tuned. The details around this vulnerability continue to unfold. As they do, you’ll find further guidance that can help keep you and your family protected from this or any follow-on threats associated with this issue.
The post Concerned by the Security Risk Affecting Popular Services and Apps? Here’s What We Know. 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.

We all know the frustration. A new piece of tech isn’t working the way it should. Or maybe setting it up is simply turning into a royal pain. Grrr, right? Just make sure that when you go on the hunt for some help, you don’t let a tech support scam get the better of you.
Like so many scams out there, tech support scams play on people’s emotions. Specifically, the frustration you feel when things don’t work right. You want that problem fixed right now. So much so that you may not pay close enough attention to that tech support link you found in a search or came across in an ad. Tech support that looks legitimate but isn’t.
Tech support scams make good money for bad actors. In fact, the larger tech support scam operations organize and run themselves like a business, with call centers, marketing teams, finance groups, and so forth—and can rack up some serious profits to boot.
They make their money in several ways. Sometimes they’ll charge large fees to fix a non-existent problem. Other times, they’ll install information-stealing malware under the guise of software that’s supposed to correct an issue. In some cases, they’ll ask for remote access to your computer to perform a diagnosis but access your computer to steal information instead.
Fortunately, these scams are rather easy to spot. And avoid. If you know what to look for.
Let’s start with a quick overview of tech support scams. They tend to work in two primary ways.
This could be a phone call that comes from someone posing as a rep from “Microsoft” or “Apple.” The scammer on the other end of the line will tell you that there’s something wrong with your computer or device. Something urgently wrong. And then offers a bogus solution to the bogus problem, often at a high cost. Similarly, they may reach you by way of a pop-up ad. Again telling you that your computer or device is in need of urgent repair. These can find you a few different ways:
These are phony services and sites that pose as legitimate tech support but are anything but. They’ll place search ads, post other ads in social media, and so forth, ready for you to look up and get in touch with when you have a problem that you need fixed. Examples include:
While tech support scammers can and do prey on older computer users, they’re not the only ones. An apparent lack of computer savviness certainly makes older users an attractive target, yet it also seems that an apparent overconfidence in one’s savviness makes younger victims susceptible to tech support scams too. Turns out that the growing majority of victims worldwide are between 18 and 35 years old, a group that has known the internet for most, if not all, of their lives. That’s according to research from Microsoft’s Digital Crimes Unit, which found the 1 in 10 of people between the ages of 18 and 35 who encountered a tech support scam fell for it and lost money.
Whatever the age group, the U.S. Federal Trade Commission (FTC) says that the reported losses in the U.S. are into the millions, which of course does not account for the assumedly millions more that do not go reported.
Lastly, a good piece of general advice is to keep your devices and apps up to date. Regular updates often include security fixes and improvements that can help keep scammers and hackers at bay. You can set your devices and apps to download them automatically. And if you need to get an update or download it on your own, get it from the company’s official website. Stay away from third-party sites that may host malware.
This will provide protection if the scammer was able to access your account passwords in some form. While this can be a big task, it’s a vital one. A password manager that’s part of comprehensive online protection can make it much easier.
Delete files or apps that the software says is an issue. Do the same for other devices on your network too. Experienced and determined scammers can infect them as well simply by gaining access to one device on your network.
Contact your bank, credit card company, online payment platform, or wire transfer service immediately to reverse the charges. File a fraud complaint as well. The sooner you act, the better chance you have of recovering some or all your money. (Note that this is a good reason to use credit cards for online purchases, as they afford extra protection that debit cards and other payment services do not.)
In the U.S., you can contact https://www.ftc.gov/complaint, which reports the claim to thousands of law enforcement agencies. While they cannot resolve your individual issue, your report can help with broader investigations and build a case against scammers—which can make the internet safer for others. Their list of FAQs is particularly helpful too, answering important questions like “how do I get my money back?”
Here’s to holiday tech that works. And to quick fixes when things don’t go as planned. In all, if you find yourself staring down a technical issue, go straight to the source for help as we’ve outlined above. As you can see, scammers have burrowed themselves alongside otherwise legitimate ads, search results, and forums online, ready to take advantage of you when you need to get things working right.
Likewise, keep an eye and ear open for those scammers who’ll reach out to you, particularly this time of year when so many people are getting so many new devices. Realizing that legitimate tech support won’t call you out of the blue is a great place to start. In all, go with the pros you know—the ones you can reach at the companies you trust.

Something’s not right. Maybe your phone is losing its charge way too quickly. Or one day it suddenly starts turning itself off and on again. Perhaps it’s running hot, so hot it’s hard to hold. Likewise, you might see outgoing calls that you never dialed or strange spikes in your data usage. Signs like these could mean that your smartphone’s been hacked. Learn how to protect your smartphone with McAfee Mobile Security
Several signs of a potential smartphone hack can look like a technical issue, at least on the surface. Yet the fact is that these issues may be a symptom of a deeper problem, such as malware installed on your smartphone. Malware can eat up system resources or conflict with other apps and your operating system, all of which can cause your phone to act sluggish or erratically.
Yet, in a way, that’s good news. Because malware can run inefficiently on your phone and create hiccups both large and small, it can tip you off to its presence. And with all the important information we carry in the palms of our hands nowadays, that’s good news twice over. Knowing the signs, subtle or otherwise can alert you to an otherwise largely invisible problem.
Whether hackers physically sneak it onto 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:
Maybe you’ve seen some of the signs we mentioned earlier. Is your device operating slower, are web pages and apps harder to load, or does your battery never seem to keep a charge? These are all signs that you could have malware running in the background, zapping your phone’s resources.
Like the performance issues above, malware or mining apps running in the background can burn extra computing power (and data). Aside from sapping performance, malware and mining apps can cause your phone to run hot or even overheat.
If you find apps you haven’t downloaded, or calls, texts, and emails that you didn’t send, that’s a red flag. A hacker may have hijacked your phone to send premium-rate calls or messages or to spread malware to your contacts. Similarly, if you see spikes in your data usage, that could be a sign of a hack as well.
Malware can also be behind spammy pop-ups, changes to your home screen, or bookmarks to suspicious websites. In fact, if you see any configuration changes you didn’t personally make, this is another big clue that your smartphone has been hacked.
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:
The post How To Tell If Your Smartphone Has Been Hacked appeared first on McAfee Blog.
For over a decade, the Internet Corporation for Assigned Names and Numbers (ICANN) and its multi-stakeholder community have engaged in an extended dialogue on the topic of DNS abuse, and the need to define, measure and mitigate DNS-related security threats. With increasing global reliance on the internet and DNS for communication, connectivity and commerce, the members of this community have important parts to play in identifying, reporting and mitigating illegal or harmful behavior, within their respective roles and capabilities.
As we consider the path forward on necessary and appropriate steps to improve mitigation of DNS abuse, it’s helpful to reflect briefly on the origins of this issue within ICANN, and to recognize the various and relevant community inputs to our ongoing work.
As a starting point, it’s important to understand ICANN’s central role in preserving the security, stability, resiliency and global interoperability of the internet’s unique identifier system, and also the limitations established within ICANN’s bylaws. ICANN’s primary mission is to ensure the stable and secure operation of the internet’s unique identifier systems, but as expressly stated in its bylaws, ICANN “shall not regulate (i.e., impose rules and restrictions on) services that use the internet’s unique identifiers or the content that such services carry or provide, outside the express scope of Section 1.1(a).” As such, ICANN’s role is important, but limited, when considering the full range of possible definitions of “DNS Abuse,” and developing a comprehensive understanding of security threat categories and the roles and responsibilities of various players in the internet infrastructure ecosystem is required.
In support of this important work, ICANN’s generic top-level domain (gTLD) contracted parties (registries and registrars) continue to engage with ICANN, and with other stakeholders and community interest groups, to address key factors related to effective and appropriate DNS security threat mitigation, including:
To better understand the various roles, responsibilities and processes, it’s important to first define illegal and abusive online activity. While perspectives may vary across our wide range of interest groups, the emerging consensus on definitions and terminology is that these activities can be categorized as DNS Security Threats, Infrastructure Abuse, Illegal Content, or Abusive Content, with ICANN’s remit generally limited to the first two categories.
Behavior within each of these categories constitutes abuse, and it is incumbent on members of the community to actively work to combat and mitigate these behaviors where they have the capability, expertise and responsibility to do so. We recognize the benefit of coordination with other entities, including ICANN within its bylaw-mandated remit, across their respective areas of responsibility.
The ICANN Organization has been actively involved in advancing work on DNS abuse, including the 2017 initiation of the Domain Abuse Activity Reporting (DAAR) system by the Office of the Chief Technology Officer. DAAR is a system for studying and reporting on domain name registration and security threats across top-level domain (TLD) registries, with an overarching purpose to develop a robust, reliable, and reproducible methodology for analyzing security threat activity, which the ICANN community may use to make informed policy decisions. The first DAAR reports were issued in January 2018 and they are updated monthly. Also in 2017, ICANN published its “Framework for Registry Operators to Address Security Threats,” which provides helpful guidance to registries seeking to improve their own DNS security posture.
The ICANN Organization also plays an important role in enforcing gTLD contract compliance and implementing policies developed by the community via its bottom-up, multi-stakeholder processes. For example, over the last several years, it has conducted registry and registrar audits of the anti-abuse provisions in the relevant agreements.
The ICANN Organization has also been a catalyst for increased community attention and action on DNS abuse, including initiating the DNS Security Facilitation Initiative Technical Study Group, which was formed to investigate mechanisms to strengthen collaboration and communication on security and stability issues related to the DNS. Over the last two years, there have also been multiple ICANN cross-community meeting sessions dedicated to the topic, including the most recent session hosted by the ICANN Board during its Annual General Meeting in October 2021. Also, in 2021, ICANN formalized its work on DNS abuse into a dedicated program within the ICANN Organization. These enforcement and compliance responsibilities are very important to ensure that all of ICANN’s contracted parties are living up to their obligations, and that any so-called “bad actors” are identified and remediated or de-accredited and removed from serving the gTLD registry or registrar markets.
The ICANN Organization continues to develop new initiatives to help mitigate DNS security threats, including: (1) expanding DAAR to integrate some country code TLDs, and to eventually include registrar-level reporting; (2) work on COVID domain names; (3) contributions to the development of a Domain Generating Algorithms Framework and facilitating waivers to allow registries and registrars to act on imminent security threats, including botnets at scale; and (4) plans for the ICANN Board to establish a DNS abuse caucus.
As early as 2009, the ICANN community began to identify the need for additional safeguards to help address DNS abuse and security threats, and those community inputs increased over time and have reached a crescendo over the last two years. In the early stages of this community dialogue, the ICANN Governmental Advisory Committee, via its Public Safety Working Group, identified the need for additional mechanisms to address “criminal activity in the registration of domain names.” In the context of renegotiation of the Registrar Accreditation Agreement between ICANN and accredited registrars, and the development of the New gTLD Base Registry Agreement, the GAC played an important and influential role in highlighting this need, providing formal advice to the ICANN Board, which resulted in new requirements for gTLD registry and registrar operators, and new contractual compliance requirements for ICANN.
Following the launch of the 2012 round of new gTLDs, and the finalization of the 2013 amendments to the RAA, several ICANN bylaw-mandated review teams engaged further on the issue of DNS Abuse. These included the Competition, Consumer Trust and Consumer Choice Review Team (CCT-RT), and the second Security, Stability and Resiliency Review Team (SSR2-RT). Both final reports identified and reinforced the need for additional tools to help measure and combat DNS abuse. Also, during this timeframe, the GAC, along with the At-Large Advisory Committee and the Security and Stability Advisory Committee, issued their own respective communiques and formal advice to the ICANN Board reiterating or reinforcing past statements, and providing support for recommendations in the various Review Team reports. Most recently, the SSAC issued SAC 115 titled “SSAC Report on an Interoperable Approach to Addressing Abuse Handling in the DNS.” These ICANN community group inputs have been instrumental in bringing additional focus and/or clarity to the topic of DNS abuse, and have encouraged ICANN and its gTLD registries and registrars to look for improved mechanisms to address the types of abuse within our respective remits.
During 2020 and 2021, ICANN’s gTLD contracted parties have been constructively engaged with other parts of the ICANN community, and with ICANN Org, to advance improved understanding on the topic of DNS security threats, and to identify new and improved mechanisms to enhance the security, stability and resiliency of the domain name registration and resolution systems. Collectively, the registries and registrars have engaged with nearly all groups represented in the ICANN community, and we have produced important documents related to DNS abuse definitions, registry actions, registrar abuse reporting, domain generating algorithms, and trusted notifiers. These all represent significant steps forward in framing the context of the roles, responsibilities and capabilities of ICANN’s gTLD contracted parties, and, consistent with our Letter of Intent commitments, Verisign has been an important contributor, along with our partners, in these Contracted Party House initiatives.
In addition, the gTLD contracted parties and ICANN Organization continue to engage constructively on a number of fronts, including upcoming work on standardized registry reporting, which will help result in better data on abuse mitigation practices that will help to inform community work, future reviews, and provide better visibility into the DNS security landscape.
It is important to note that groups outside of ICANN’s immediate multi-stakeholder community have contributed significantly to the topic of DNS abuse mitigation:
Internet & Jurisdiction Policy Network
The Internet & Jurisdiction Policy Network is a multi-stakeholder organization addressing the tension between the cross-border internet and national jurisdictions. Its secretariat facilitates a global policy process engaging over 400 key entities from governments, the world’s largest internet companies, technical operators, civil society groups, academia and international organizations from over 70 countries. The I&JP has been instrumental in developing multi-stakeholder inputs on issues such as trusted notifier, and Verisign has been a long-time contributor to that work since the I&JP’s founding in 2012.
DNS Abuse Institute
The DNS Abuse Institute was formed in 2021 to develop “outcomes-based initiatives that will create recommended practices, foster collaboration and develop industry-shared solutions to combat the five areas of DNS Abuse: malware, botnets, phishing, pharming, and related spam.” The Institute was created by Public Interest Registry, the registry operator for the .org TLD.
Global Cyber Alliance
The Global Cyber Alliance is a nonprofit organization dedicated to making the internet a safer place by reducing cyber risk. The GCA builds programs, tools and partnerships to sustain a trustworthy internet to enable social and economic progress for all.
ECO “topDNS” DNS Abuse Initiative
Eco is the largest association of the internet industry in Europe. Eco is a long-standing advocate of an “Internet with Responsibility” and of self-regulatory approaches, such as the DNS Abuse Framework. The eco “topDNS” initiative will help bring together stakeholders with an interest in combating and mitigating DNS security threats, and Verisign is a supporter of this new effort.
Other Community Groups
Verisign contributes to the anti-abuse, technical and policy communities: We continuously engage with ICANN and an array of other industry partners to help ensure the continued safe and secure operation of the DNS. For example, Verisign is actively engaged in anti-abuse, technical and policy communities such as the Anti-Phishing and Messaging, Malware and Mobile Anti-Abuse Working Groups, FIRST and the Internet Engineering Task Force.
As a leader in the domain name industry and DNS ecosystem, Verisign supports and has contributed to the cross-community efforts enumerated above. In addition, Verisign also engages directly by:
An important concept and approach for mitigating illegal and abusive activity online is the ability to engage with and rely upon third-party “trusted notifiers” to identify and report such incidents at the appropriate level in the DNS ecosystem. Verisign has supported and been engaged in the good work of the Internet & Jurisdiction Policy Network since its inception, and we’re encouraged by its recent progress on trusted notifier framing. As mentioned earlier, there are some key questions to be addressed as we consider the viability of engaging trusted notifiers or building trusting notifier entities, to help mitigate illegal and abusive online activity.
Verisign’s recent experience with the U.S. government (NTIA and FDA) in combating illegal online opioid sales has been very helpful in illuminating a possible approach for third-party trusted notifier engagement. As noted, we have also benefited from direct engagement with the Internet Watch Foundation and law enforcement in combating CSAM. These recent examples of third-party engagement have underscored the value of a well-formed and executed notification regime, supported by clear expectations, due diligence and due process.
Discussions around trusted notifiers and an appropriate framework for engagement are under way, and Verisign recently engaged with other registries and registrars to lead the development of such a framework for further discussion within the ICANN community. We have significant expertise and experience as an infrastructure provider within our areas of technical, legal and contractual responsibility, and we are aggressive in protecting our operations from bad actors. But in matters related to illegal or abusive content, we need and value contributions from third parties to appropriately identify such behavior when supported by necessary evidence and due diligence. Precisely how such third-party notifications can be formalized and supported at scale is an open question, but one that requires further exploration and work. Verisign is committed to continuing to contribute to these ongoing discussions as we work to mitigate illegal and abusive threats to the security, stability and resiliency of the internet.
Over the last several years, DNS abuse and DNS-related security threat mitigation has been a very important topic of discussion in and around the ICANN community. In cooperation with ICANN, contracted parties, and other groups within the ICANN community, the DNS ecosystem including Verisign has been constructively engaged in developing a common understanding and practical work to advance these efforts, with a goal of meaningfully reducing the level and impact of malicious activity in the DNS. In addition to its contractual compliance functions, ICANN’s contributions have been important in helping to advance this important work and it continues to have a critical coordination and facilitation function that brings the ICANN community together on this important topic. The ICANN community’s recent focus on DNS abuse has been helpful, significant progress has been made, and more work is needed to ensure continued progress in mitigating DNS security threats. As we look ahead to 2022, we are committed to collaborating constructively with ICANN and the ICANN community to deliver on these important goals.

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.

How do you connect online these days? I’ll give you an example from my own life: From my 15-year old son to my 80-year-old mother, not one of us leaves the house without our phone. And today, there isn’t a single thing you can’t do on your phone. It’s the minicomputer that goes where you go.
This trend in the way we connect is reflected in recent data too. In fact, we’ve found that the average consumer spends 6 hours and 55 min online per day, split between mobile (52%) and desktop (48%). Whether you’re a Boomer, Gen X, a Millennial, or Gen Z, the way you connect online is diverse and specific to you.
As for what we’re doing online? It’s just about everything. After all, we spend an average of 7 hours per day on connected devices and the pandemic has forced us to do even more online. The downside to this rapid change in the way we live is that we are opening ourselves up to more risk which leaves consumers feeling highly concerned about their ability to keep their personal info secure or private. We need new protection for this new normal.
What all these changes mean is that you’re able to have the same online experience regardless of where you are, what you’re doing, or what device you’re using. Your favorite streaming service is a great example – you can just as easily find a movie on a tablet as you can on your laptop. In fact, you can pause the movie you’re watching on that tablet and pick up where you left off on your laptop. Your experience with online security should offer the same convenience and familiarity. More importantly, online protection should give you a feeling of confidence however or wherever you choose to connect.
This means knowing your personal info is secure even when accessing an unsecured network, your browsing habits remain private, and you can take necessary actions should your information be compromised. To put it another way, YOU are what we’re focused on protecting and we do that by making sure everything you connect with is also secure.
A phone is the remote control for your life. From the palm of your hand, you’re able to shop, browse, stream, and create – everything you do online you can now do from your phone. So, it’s crucial that your phone be a major focus of our online protection. The new mobile app makes it easier to get robust protection for your identity, privacy, and phone. Let’s look at a few of the capabilities offered by the new mobile app.
Think about all the online accounts you’ve created in the past year. How many of them do you use regularly? Sometimes I think I have more food delivery apps on my phone than I do restaurants to use them on. Regardless of how often you use an account (or if you no longer use it at all!), any personal information (like emails, addresses, credit cards) added to it is available online and vulnerable to breaches. McAfee Security comes with identity protection, a feature that monitors your personal information and then notifies you when there’s a risk of your data being compromised. What this means is that if we detect that your data was stolen, you’ll be alerted an average of 10 months earlier than similar services, so you can act before your data is used illegally or shows up on the dark web.
Let’s say you’re about to use the free internet at your favorite café for a speedier connection. Time to flip on your virtual private network (VPN). Forget about digging through a sea of menus to find your VPN. The new mobile app offers a seamless VPN experience so you can keep your activity hidden on less-than-secure Wi-Fi. Or, better yet, you can set up a Secure VPN to automatically turn on for unsecured Wi-Fi networks. Whatever you choose, Secure VPN keeps your personal data and location private anywhere you go with unlimited data and bank-grade Wi-Fi encryption.
At the end of the day, phones are devices and they’re vulnerable to viruses, malware, and, increasingly, malicious apps. The new McAfee Mobile app offers an antivirus scan for Android phones and system scans to see if your passcode is strong enough and that your OS is up to date on iOS devices.
Most importantly, the app is part of McAfee’s total online protection, so the experience on your phone is the same as on your PC. It’s protection that goes where you go – at home on your PC, or on the go with your mobile.
If you’re an existing McAfee subscriber using McAfee Total Protection or McAfee LiveSafe, you can get the app right now. And, if you’ve already got the app installed, just make sure it’s up-to-date and you’ll be all set with the new look and features.
Interested in trying the app out? You can buy or get a free trial of McAfee Total Protection here and get started today.

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.

How does that information get collected in the first place? We share personal information with companies for multiple reasons simply by going about our day—to pay for takeout at our favorite restaurant, to check into a hotel, or to collect rewards at the local coffee shop. Of course, we use our credit and debit cards too, sometimes as part of an online account that tracks our purchase history.
In other words, we leave trails of data practically wherever we go these days, and that data is of high value to hackers. Thus, all those breaches we read about.
Whether it’s a major breach that exposes millions of records or one of many other smaller-scale breaches like the thousands that have struck healthcare providers, each one serves as a reminder that data breaches happen regularly and that we could find ourselves affected. Depending on the breach and the kind of information you’ve shared with the business or organization in question, information stolen in a breach could include:
What do crooks do with that data? Several things. Apart from using it themselves, they may sell that data to other criminals. Either way, this can lead to illicit use of credit and debit cards, draining of bank accounts, claiming tax refunds or medical expenses in the names of the victims, or, in extreme cases, assuming the identity of others altogether.
In all, data is a kind of currency in of itself because it has the potential to unlock several aspects of victim’s life, each with its own monetary value. It’s no wonder that big breaches like these have made the news over the years, with some of the notables including:
Facebook – 2019: Two sets of data exposed the records of more than 530 million users, including phone numbers, account names, and Facebook IDs.
Marriott International (Starwood) – 2018: Half a million guests had names, email and physical mailing addresses, phone numbers, passport numbers, Starwood Preferred Guest account information, dates of birth, and other information about their stays exposed.
Equifax – 2017: Some 147 million records that included names, addresses, dates of birth, driver’s license numbers, and Social Security Numbers were exposed, along with a relatively small subset of 200,000 victims having their credit card information exposed as well.
As mentioned, these are big breaches with big companies that we likely more than recognize. Yet smaller and mid-sized businesses are targets as well, with some 43% of data breaches involving companies of that size. Likewise, restaurants and retailers have seen their Point-of-Sale (POS) terminals compromised, right on down to neighborhood restaurants.
When a company experiences a data breach, customers need to realize that this could impact their online safety. If your favorite coffee shop’s customer database gets leaked, there’s a chance that your personal or financial information was exposed. However, this doesn’t mean that your online safety is doomed. If you think you were affected by a breach, there are multiple steps you can take to help protect yourself from the potential side effects.
One of the most effective ways to determine whether someone is fraudulently using one or more of your accounts is to check your statements. If you see any charges that you did not make, report them to your bank or credit card company immediately. They have processes in place to handle fraud. While you’re with them, see if they offer alerts for strange purchases, transactions, or withdrawals.
File a police report and a Federal Trade Commission (FTC) Identity Theft Report. This will help in case someone uses your Social Security number to commit fraud, since it will provide a legal record of the theft. The FTC can also assist by guiding you through the identity theft recovery process as well. Their site offers a step-by-step recovery plan that you can follow and track your progress as you go.
If you suspect that your data might have been compromised, place a fraud alert on your credit. This not only ensures that any new or recent requests undergo scrutiny, but also allows you to have extra copies of your credit report so you can check for suspicious activity. You can place one fraud alert with any of the three major credit reporting agencies (Equifax, Experian, TransUnion) and they will notify the other two. A fraud alert typically lasts for a year, although there are options for extending it as well.
Freezing your credit will make it highly difficult for criminals to take out loans or open new accounts in your name, as a freeze halts all requests to pull your credit—even legitimate ones. In this way, it’s a far stronger measure than placing a fraud alert. Note that if you plan to take out a loan, open a new credit card, or other activity that will prompt a credit report, you’ll need to take extra steps to see that through while the freeze is in place. (The organization you’re working with can assist with the specifics.) Unlike the fraud alert, you’ll need to contact each major credit reporting agency to put one in place. Also, a freeze lasts as long as you have it in place. You’ll have to remove it yourself, again with each agency.
Ensure that your passwords are strong and unique. Many people utilize the same password or variations of it across all their accounts. Therefore, be sure to diversify your passcodes to ensure hackers cannot obtain access to all your accounts at once, should one password be compromised. You can also employ a password manager to keep track of your credentials, such as one you’ll find in comprehensive online protection software.
A solution such as this will help you to monitor your accounts and alert you of any suspicious activity. Specifically, our own Identity Protection Service will monitor several types of personally identifiable information, alert you of potentially stolen personal info, and offer guided help to neutralize the threat. Also, it can help you steer clear of some types of theft with preventative guidance that can help keep theft from happening in the first place. With this set up on your computers and smartphone you can stay in the know and address issues immediately.
To use your credit card safely online to make purchases, add both a VPN and password manager into your toolbox of security solutions. A VPN keeps your shopping experience private, while a password manager helps you keep track of and protect all your online accounts. Again, you’ll find a VPN as part of comprehensive online protection software.

You may have spotted the news last week that U.S. federal prosecutors brought charges against the former chief security officer of Uber. At issue was a breach that occurred in 2016, where prosecutors allege that he covered up a $100,000 payoff to the hackers responsible for the attack. The specific charges are obstructing justice and concealing a felony for the alleged cover-up.
While the breach itself is relatively old news and the company has since paid a $148 million settlement along with an agreement to regular audits of its privacy and security systems, this is a reminder that breaches happen. What’s more, it may be some time before you become aware of them, even in instances when companies move quickly, transparently, and in your best interest.
According to research we recently published, nearly three-quarters of all breaches have required public disclosure or have affected financial results, up five points from 2015. Additionally, industry studies show that it can take roughly nine month on average to identify and contain a breach. Yes, that’s more than nine months, and a lot can happen to your credit in that timeframe. Thus the onus is on us to be vigilant about our own credit.
Here’s a quick list of things you can do right now to keep on top of your credit—and that you can do on an ongoing basis as well, because that’s what it takes to keep tabs on your personal info today.
Closely monitor your online accounts: Whether it’s your credit card statements, banking statements, or your individual accounts for services like Uber, review them closely. If you see any suspicious activity, notify the institution or service and put a freeze on your account(s) as needed. Even a small charge can indicate a bigger problem, as that means your information is out there in the wild and could be used for bigger purchases down the pike. In the event you feel your Uber account has been compromised, you can contact them via their “I think my Uber account has been hacked” page.
Update your settings: That includes your privacy settings in addition to changing your password. As far as passwords go, strong and layered passwords are best, and never reuse your credentials across different platforms. Plus, update your passwords on a regular basis. That’ll further protect your data. Using a password manager will help you keep on top of it all, while also storing your passwords securely.
Enable two-factor authentication: While a strong and unique password is a good first line of defense, enabling app-based two-factor authentication across your accounts will help your cause by providing an added layer of security.
Check your credit: Depending on where you live, there are different credit reporting agencies that keep a centralized report of all your credit activities. For example, the major agencies in the U.S. are primarily Equifax, Experian, and TransUnion. Likewise in the U.S., the Fair Credit Reporting Act (FCRA) requires these agencies to provide you with a free credit check at least once every 12 months. It’s a relatively quick process, and you might be surprised what you find—anywhere to incorrect address information to bills falsely associated with your name. Get your free credit report here from the U.S. Federal Trade Commission (FTC). Other nations provide similar services, such as the free credit reports for UK customers.
Freeze your credit: Freezing your credit will make it impossible for criminals to take out loans or open up new accounts in your name. To do this effectively, you will need to freeze your credit at each of the three major credit-reporting agencies (Equifax, TransUnion, and Experian).
Consider using identity theft protection: A solution like McAfee Identify Theft Protection will help you to monitor your accounts and alert you of any suspicious activity in addition to the activities I’ve listed above. Additionally, you can use a comprehensive security solution such as McAfee Total Protection to help protect your devices and data from known vulnerabilities and emerging threats.
For all the technology we have at our fingertips, our best defense is our eyes. Keeping a lookout for fishy activity and following up with family members when unfamiliar charges show up on your accounts will help you keep your good name in good standing.
The thing is, we never know when the next data breach might hit and how long it may be until that information is discovered and finally disclosed to you. Staying on top of credit has always been important, but given all our apps, accounts, and overall exposure these days, it’s a must.

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:

If you find that your email has been hacked, one of your immediate reactions is wondering what you should next.
The answer: take a deep breath and jump into action. There are five steps can help you prevent or minimize any damage done by a compromised account.
So why do hackers go after email accounts? Fact is, that email account of yours is a treasure trove. There’s a good chance it contains years of correspondence with friends and family, along with yet more email from banks, online retailers, doctors, contractors, business contacts, and more. In all, your email packs a high volume of personal info in one place, which makes your email account a top prize for hackers.
Let’s take a look at how you can take back control of your email account, along with some things you can do to keep it from getting hacked in the first place.
This one speaks for itself. You go to check your email and find that your username and password combination has been rejected. You try again, knowing you’re using the right password, and still no luck. There’s a chance that a hacker has gotten a hold of your password, logged in, and then changed the password—thus locking you out and giving them control of your account.
Hackers often compromise email accounts to spread malware on a large scale. By blasting emails to everyone on your hacked contact list, they can reach dozens, even hundreds, of others with a bogus email that may include an attachment that’s infected with malware. And no doubt about it, some of those emails can look a little odd. They don’t sound or read at all like the person they’re trying to impersonate—you—to the extent that some of your contacts may ask if this email really came from you.
On the flip side, this is a good reason to never open attachments you weren’t expecting. Likewise, if you get a somewhat strange email from a friend or business contact, let them know. You may be the first indication they get that their email has been compromised.
A sluggish device could be a sign of malware in general. The thing with malware is that it tends to act like a system and resource hog, which may cause your device to run slowly, to turn off and on again suddenly, or even run hot. In some cases, the malware is logging keystrokes on your computer or taps on your phone to siphon off things like usernames and passwords so that a hacker can take control of the accounts associated with them—such as your email, not to mention your bank accounts. This makes a strong case for antivirus and antimalware protection that’s automatically kept up to date to protect against the latest threats.
Change your password for your email account if you can. Make it a strong, unique password—don’t reuse a password from another account. Next, update the passwords for other accounts if you use the same or similar passwords for them. (Hackers count on people using simpler and less unique passwords across their accounts—and on people reusing passwords in general.) A password manager that’s included with comprehensive online protection software can do that work for you.
In the case where you’ve been locked out of your account because you think the hacker has changed the password, your email provider should have a webpage dedicated to recovering your account in the event of a lost or stolen password. (For example, Google provides this page for users of Gmail and their other services.) This is a good reason to keep your security questions and alternate contact information current with your provider, as this is the primary way to regain control of your account.
As mentioned above, a big part of the hacker’s strategy is to get their hooks into your address book and spread malware to others. As quickly as you can, send a message to all your email contacts and let them know that your email has been compromised. And if you’ve done so, let them know that you’ve reset your password so that your account is secure again. Likewise alert them that they shouldn’t open any emails or attachments from you that were sent during the time your account was compromised.
Also as mentioned above, there are several ways that a hacker can get a hold of your email account information—one of them by using malware. Give your device a thorough virus scan with comprehensive online protection software to ensure your device is free from malware. Set up a regular scan to run automatically if you haven’t already. That will help keep things clean in the long run.
Sometimes one bad hack leads to another. If someone has access to your email and all the messages in it, they may have what they need to conduct further attacks. Take a look at your other accounts across banking, finances, social media, and other services you use and keep an eye out for any unusual activity.
More broadly speaking, your email account is one of the several pieces that make up the big picture of your online identity. Other important pieces include your online banking accounts, online shopping accounts, and so on. No question about it, these are things you want to keep tabs on.
With that, check your credit report for any signs of strange activity. Your credit report 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.
Beyond keeping tabs on your identity, you can protect it as well. Online identity protection such as ours can provide around-the-clock monitoring of your email addresses and bank accounts with up to $1M of ID theft insurance in the event your identity gets compromised. Additionally, it can put an identity recovery pro on the case if you need assistance in the wake of an attack or breach. Taking a step like this can help keep your email account safer from attack in the first place—along with many others as well.

With the acceleration of cloud migration initiatives—partly arising the need to support a remote workforce during the pandemic and beyond—enterprises are finding that this transformation has introduced new operational complexities and security vulnerabilities. Among these are potential misconfigurations, poorly secured interfaces, Shadow IT (access to unauthorized applications), and an increasing number of connected devices and users. To navigate these challenges, enterprises are relying on managed service providers to monitor and protect their cloud environment.
To better serve its customers and secure its own environments, one global technology provider decided to expand its existing on-premises data loss protection (DLP) and web protection with a comprehensive and robust cloud security strategy based on solutions from the MVISION portfolio of solutions. Already a long-time user of McAfee Enterprise on-premises solutions, the global technology provider not only secured its internal cloud infrastructure consisting of more than 5,000 endpoints across over 30 locations worldwide, they also applied the same approach to the millions of endpoints they manage for more than 10,000 customers.
A primary objective for the global technology provider is securing data in the cloud in Software-as-a-Service (SaaS) applications (Microsoft Office 365, OneDrive, Salesforce, and others) and Infrastructure-as-a-Service (IaaS) platforms (Microsoft Azure, Amazon Web Services, Google Cloud Platform).
As a first step in its cloud journey, the global technology provider evaluated a number of cloud access security brokers (CASB) solutions. Ultimately, they decided to implement MVISION Cloud for AWS, Office 365, and Shadow IT. In addition to providing comprehensive visibility into cloud app usage, these solutions help with compliance; data loss prevention (DLP) by monitoring the movement of sensitive and confidential data content traveling to or from the cloud, within the cloud, and cloud to cloud; and detection and remediation of threats primarily through user and entity behavior analytics (UEBA).
But the global technology provider didn’t stop there. When we rolled out MVISION Unified Cloud Edge, the global technology provider tested it and enthusiastically adopted it. As defined by Gartner, MVISION Unified Cloud Edge is an industry-leading example of Secure Access Service Edge (SASE), a security framework that brings together network connectivity and security into a single, cloud-delivered solution that supports business transformation, edge computing, and workforce mobility.
The global technology provider has reaped multiple advantages from this implementation across its own internal environment and for its customers.
MVISION Unified Cloud Edge combines multiple capabilities under one umbrella: CASB functionality with web proxy and DLP with a single administrative hub, ePolicy Orchestrator® (ePO) for streamlined management.
MVISION Unified Cloud Edge capabilities and the ease of integration with the McAfee Enterprise ecosystem has made life easier for the global technology provider’s team, saving time and resources. Now they can set consistent policies from device to cloud and provide users with accelerated and secure access to the tools they use every day, such as Box, Dropbox, and others. As the information security operations manager points out: “A single management console reduces overhead as does being able to set policies that we can sync and apply to multiple data sources on multiple cloud solutions, without having to recreate rules.”
MVISION Unified Cloud Edge has also enabled the global technology provider to further boost its cloud data protection. For example, it can detect data that is improperly managed and stored. Now the organization can apply their existing on-premises data policies to the cloud. For example, they can prevent certain user behaviors that may put both corporate and customer cloud data at risk. These include copying data to cloud apps or USBs, printing it, taking screen captures, accessing risky websites, and uploading data to unauthorized websites.
To create a more secure internal environment, MVISION Unified Cloud Edge has been invaluable for the global security provider. They have a better handle on the applications that are being used across their company. The solution also provides risk scores for the cloud apps that are being used to help steer users away from Shadow IT and toward using only authorized apps. When employees propose new apps to help them do their jobs better, the IT security team can check the security of these apps against requirements and make any necessary modifications to ensure compliance.
“The Shadow IT CASB automatically blocks all cloud services that are deemed high risk, both at our on-premises Web Gateway and the built-in cloud web gateway manager. So, when users attempt to use an unsanctioned SaaS application, they see a message explaining that the app is not safe,” notes the information security operations manager.
The global technology provider also sells SaaS solutions to its clients. With MVISION Unified Cloud Edge, the global technology provider can protect data on any newly sanctioned SaaS applications at no extra cost.”
After a successful experience with McAfee Enterprise overall and specifically with the implementation of MVISION Unified Cloud Edge, the information security operation manager recommends the solution to any organization beginning or in the midst of migrating to the cloud.
“I would advise other companies thinking about their cloud transformation journey to seriously consider MVISION Unified Cloud Edge . . . It has a very user-friendly interface and does so much out of the box,” he asserts. “The level of granularity in policy setting lets you do things you don’t think possible or are much easier to accomplish than you realize. . . I don’t think any other vendor offers such a complete package.”

Cloud Security Gateways (CSGs) are one of the hottest and most sought-after technologies in the market today, driven by the adoption of cloud services for business transformation and the acceptance of hybrid workforce policies. CSGs, also commonly known as Cloud Access Security Brokers (CASBs), are responsible for enforcing security policies to protect cloud-hosted corporate assets from advanced threats, while enabling seamless and secure access to these assets from any location and device.
We have witnessed an exponential growth in cloud usage in the past two years, primarily driven by remote workforce adoption. Based on the data collected by our research team from millions of connected McAfee Enterprise users across the globe, the overall usage of enterprise cloud services spiked by 50% across all industries, while the collaboration services witnessed an increase of up to 600% in usage. This led to an astonishing 630% increase in external attacks on the cloud accounts. Taking all these factors and trends into consideration, CSGs have become a highly essential element of any organization’s cloud security strategy, playing the most critical role for enabling data protection, threat prevention and compliance in the cloud.
McAfee Enterprise continues to innovate in the cloud security space with a laser-focused strategy towards empowering our customers with the best-in-class cloud security solution. MVISION Cloud, recognized as the industry’s leading CSG solution, has become a vital part of enterprise security, allowing organizations to safely migrate to the cloud while protecting their “crown jewels” – the data. A huge testament to our cybersecurity vision is the IDC MarketScape Worldwide Cloud Security Gateways 2021 Vendor Assessment (Doc # US48334521, November 2021), and we are proud to announce that McAfee Enterprise has been recognized as a leader in the report.
According to the report, “McAfee has a strong ecosystem of security solutions, including Secure Web Gateway, CSG, and endpoint security that it can integrate to enable customers in their data loss prevention, User Behavior Analytics, XDR, and threat prevention goals. McAfee has focused on providing robust protection and DLP, with the scale and speed necessary to support large user bases.”
McAfee Enterprise’s multi-vector data protection capabilities go beyond the cloud to uniquely discover and protect sensitive assets on managed endpoints, in-network shares, and on-premises databases, enabling full scope of data protection from device-to-cloud. The industry-leading data protection and threat protection capabilities are tightly integrated with a unified policy framework that allows policy enforcement, data classification and incident management from a centralized console, reducing the cost and complexity of managing hybrid IT deployments, while improving the user experience.
Figure 1: McAfee Enterprise Multi-Vector Data Protection
MVISION Cloud is an integral component of our Unified Cloud Edge (UCE) solution, and together with McAfee Enterprise’s Next-Gen Secure Web Gateway (SWG) and MVISION Private Access (ZTNA) delivers the industry’s most comprehensive Security Services Edge (SSE) solution – the security element of the Secure Access Service Edge (SASE) framework. With McAfee Enterprise’s DLP technology being the common denominator across all the core SSE components, organizations can seamlessly utilize a unified, data-centric framework for centralized visibility and control over their entire digital footprint, while riding on an accelerated path for digital transformation and workplace mobility.
Figure 2: MVISION Unified Cloud Edge (UCE)
Our mission towards building a unified security platform for protecting data from device-to-cloud and defending against advanced threats and adversaries has established McAfee Enterprise as a leader in cybersecurity across multiple forums, and the 2021 IDC MarketScape report is another distinguished feather in our decorated cap.

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.

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.
