It would be impossible nowadays to separate our everyday lives from technology. We travel well-worn, comfortable paths online and engage in digital activities that work for us. But could those seemingly harmless habits be putting out the welcome to cyber criminals out to steal our data?
It’s a given that our “digital-first mindset” comes with inherent risks. With the work and learn from home shift looking more permanent and cybercrime on the rise, it’s imperative to adopt new mindsets and put new skills in motion. The first step with any change? Admitting your family may have a few bad habits to fix. Here are just a few to consider.
1. You share toooo much online. Too Much Information, yes, TMI. Oversharing personal information online is easy access for bad actors online. Those out to do harm online have made it their life’s work to piece together your personal details so they can steal your identity—or worse. Safe Family Tips: Encourage your family not to post private information such as their full name, family member names, city, address, school name, extracurricular activities, and pet names. Also, get in the habit of a) setting social media profiles to private, b) regularly scrubbing personal information on social profiles—this includes profile info, comments, and even captions that reveal too much c) regularly editing your friends lists to people you know and trust.
2. You’ve gotten lazy about passwords. It’s tough to keep up with everything these days. We get it. However, passwords are essential. They protect your digital life—much like locks on doors protect your physical life. Safe Family Tips: Layer up your protection. Use multi-factor authentication to safeguard user authenticity and add a layer of security to protect personal data and all family devices. Consider adding comprehensive software that includes a password manager as well as virus and malware protection. This level of protection can add both power and peace of mind to your family’s online security strategy.
3. You casually use public Wi-Fi. It’s easy to do. If you are working away from home or on a family trip, you may need to purchase something, meet a deadline, or send sensitive documents quickly. Public Wi-Fi is easy and fast, but it’s also loaded with security gaps that cybercriminals camp out on. Safe Family Tip: If you must conduct transactions on a public Wi-Fi connection, consider McAfee Total Protection. It includes antivirus and safe browsing software, plus a secure VPN.
4. You have too many unvetted apps. We love apps, but can we trust them? Unfortunately, when it comes to security and privacy, apps are notoriously risky and getting tougher to trust as app technology evolves. So, what can you do? Safe Family Tips: A few things you can do include a) Double-checking app permissions. Before granting access to an app, ask yourself: Does this app need what it’s asking me to share? Apps should not ask for access to your data, b) researching the app and checking its security level and if there have been breaches, c) reading user reviews, d) routinely deleting dormant and unused apps from your phone. This is important to do on your phone and your laptop, e) monitor your credit report for questionable activity that may be connected to a malicious app or any number of online scams.
5. You’ve gotten too comfortable online. If you think that a data breach, financial theft, or catfish scam can’t happen to you or your family, it’s a sign you may be too comfortable online. Growing strong digital habits is an ongoing discipline. If you started strong but have loosened your focus, it’s easy to get back to it. Safe Family Tips: Some of the most vulnerable areas to your privacy can be your kids’ social media. They may be oversharing, downloading malicious apps, and engaging with questionable people online that could pose a risk to your family. Consider regularly monitoring your child’s online activity (without hovering or spying). Physically pick up their devices to vet new apps and check they’ve maintained all privacy settings.
6. You lack a unified family security strategy. Consider it: If each family member owns three devices, your family has countless security gaps. Closing those gaps requires a unified plan. Safe Family Tips: a) Sit down and talk about baseline security practices every family member should follow, b) inventory your technology, including IoT devices, smartphones, game systems, tablets, and toys, c) make “keeping the bad guys out” fun for kids and a challenge for teens. Sit and change passwords together, review privacy settings, reduce friend lists. Come up with a reward system that tallies and recognizes each positive security step.
7. You ignore updates. Those updates you’re putting off? They may be annoying, but most of them are security-related, so it’s wise to install them as they come out. Safe Family Tip: Many people make it a habit to change their passwords every time they install a new update. We couldn’t agree more.
Technology continues to evolve and open extraordinary opportunities to families every day. However, it’s also opening equally extraordinary opportunities for bad actors banking on consumers’ casual security habits. Let’s stop them in their tracks. If you nodded to any of the above habits, you aren’t alone. Today is a new day, and putting better digital habits in motion begins right here, right now.

Spyware is tricky. Some types notify users that they’re monitoring activity. Others function in stealth mode and use the information they collect for nefarious purposes. Spyware is a type of software that collects data about online users and reports it to a company or an individual. What just about everyone can agree on is that anonymous browsing is looking more and more appealing and is likely the way of the future.
Here’s more about the types of spyware, which types are legal, and how you can scrub your device and live more confidently online.
Here are a few types of spyware and facts about each:
Is it legal? Definitely not!
What is its purpose? Criminal
Keyloggers are the most intrusive of the spyware variations. It does exactly as its name suggests: It takes note of keyboard strokes, logs them, and reports to the owner of the nefarious software. Once the cybercriminal has digitally looked over your shoulder at your online activity, they make note of your passwords, walk into your online accounts, and pilfer your private personal information. They could use this information to gain entry to your online bank accounts or steal your identity.
Keyloggers are downloaded onto devices (cellphones, tablets, laptops, or desktop computers) without the user’s knowledge. Cybercriminals can hide them within email attachments or in malicious web pages. So, the best way to steer clear of keyloggers is to never download attachments you’re unsure about and don’t visit sites that seem unprofessional. One rule of thumb is to mostly stick to URLs that begin with https and include a lock icon. These sites are almost always secure.
To determine if your device is infected with a keylogger, check your system’s performance. Is your device running slowly? See if there are any spikes in activity or unknown programs running in the background. This could indicate that your device is hosting a malicious program.
Is it legal? Sometimes
What is its purpose? Advertising and criminal
Adware is categorized as a type of spyware. It tracks users’ online activity and spits out targeted pop-up advertisements. If you have the pop-up blocker enabled on your browser, you’ll likely be spared from the annoyance. Additionally, pop-ups can slow your device, so that’s another reason to turn on the pop-up blocking feature. Legitimate adware often asks users to opt into targeted ads.
Adware turns malicious (and illegal) when it contains malware. Sometimes cyber criminals hide malware within pop-ups. It’s easy to accidentally hit a link within a pop-up when you’re aiming quickly for the X to close it.
It’s easy to spot a device with an adware infestation. First, the number of pop-ups will be out of control. Also, the device will crash often, run very slowly, and have a short battery life. An antivirus program will likely be able to identify and remove the culprit. You can also check out your system monitor and end tasks that are draining your device’s power.
Is it legal? Yes
What is its purpose? Advertising
Cookies are delicious, especially to advertisers who use them to better target ads and make profits selling collected user data to third-party companies. Cookies are sometimes categorized as spyware, because they log the websites you visit and report them. You may notice the banners on websites that ask you to accept cookies.
Many users today are uneasy with sharing their online activity with strangers and advertisers. Sometimes the ads that pop up on your social media feed or in sidebars seem a little too targeted and it feels like someone is listening in to your conversations and attempting to make a profit from them.
How to Browse Free of Spyware
To scrub cybercriminals from your devices and confuse advertisers, consider the following steps you can easily add to your daily routine:

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

Due to their widespread use, Office Documents are commonly used by Malicious actors as a way to distribute their malware. McAfee Labs have observed a new threat “Squirrelwaffle” which is one such emerging malware that was observed using office documents in mid-September that infects systems with CobaltStrike.
In this Blog, we will have a quick look at the SquirrelWaffle malicious doc and understand the Initial infection vector.
Geolocation based stats of Squirrelwaffle malicious doc observed by McAfee from September 2021
Here is how the face of the document looks when we open the document (figure 3). Normally, the macros are disabled to run by default by Microsoft Office. The malware authors are aware of this and hence present a lure image to trick the victims guiding them into enabling the macros.
The VBA Userform Label components present in the Word document (Figure-4) is used to store all the content required for the VBS file. In Figure-3, we can see the userform’s Labelbox “t2” has VBS code in its caption.
Sub routine “eFile()” retrieves the LabelBox captions and writes it to a C:\Programdata\Pin.vbs and executes it using cscript.exe
Cmd line: cmd /c cscript.exe C:\Programdata\Pin.vbs
The dropped VBS Script is obfuscated (Figure-5) and contains 5 URLs that host payloads. The script runs in a loop to download payloads using powershell and writes to C:\Programdata location in the format /www-[1-5].dll/. Once the payloads are downloaded, it is executed using rundll32.exe with export function name as parameter “ldr”
De-obfuscated VBS script
VBS script after de-obfuscating (Figure-6)
Different techniques & tactics are used by the malware and we mapped these with the MITRE ATT&CK platform.
Malicious doc VBA drops and invokes VBS script.
CMD: cscript.exe C:\ProgramData\pin.vbs
Rundll32.exe is used to execute the dropped payload
CMD: rundll32.exe C:\ProgramData\www1.dll,ldr

Becoming a cloud first company is an exciting and rewarding journey, but it’s also fraught with difficulties when it comes to securing an entire cloud estate. Many forwarding-thinking companies that have made massive investments in migrating their infrastructure to the cloud are facing challenges with respect to their cloud-native applications. These range from inconsistent security across cloud properties to lack of visibility into the public cloud infrastructure where cloud-native applications are hosted—and more. All of these issues can create vulnerabilities in a sprawling attack surface that can be potentially exploited by cybercriminals.
Legendary Entertainment is a global media company with multiple divisions including film, television, digital studios, and comics. Under the guidance of Dan Meacham, VP of Global Security and Corporate Operations and CSO/CISO, the multi-billion dollar organization transitioned from on-premises data centers to the cloud in 2012.
Meacham points out that it’s been a source of great pride for his security and IT teams to always be “on top of the latest and greatest” technology trends—and migration to the cloud is no exception. That’s why his interest was sparked when he learned about the rollout of the MVISION security product line early in the migration process. Its cloud-native, open architecture was exactly the right fit for Legendary Entertainment’s environment.
As a cloud-first organization, Legendary Entertainment encountered challenges that are common to many companies that have migrated their workloads, applications, and data assets to the cloud. At first, the organization attempted to rely on security services natively provided by the individual cloud service providers: Amazon Web Services (AWS), Microsoft Azure, Google Cloud Platform (GCP), and Wasabi for cloud storage. As Meacham notes, “The security from one vendor doesn’t trickle over to the others. They all have different security controls, so our cloud security was not uniform, and security management was complicated.”
In their disparate multicloud environment spanning several cloud service providers, it became time-consuming and difficult to monitor and assess the security posture of applications and workloads, such as which systems needed patching or contained critical vulnerabilities.
With multiple management consoles required for its many cloud environments, applying and enforcing uniform security policy across their cloud estate was nearly impossible without investing a lot of time, effort, and resources.
Another problem in Legendary Entertainment’s early adoption of cloud-first was shadow IT, where employees or contractors enrolled in cloud collaboration platforms that were not authorized by IT. Although the shadow IT platforms were not connected to core systems, they made it more difficult to tightly monitor data which sometimes caused cloud-enabled applications to violate security policies. It is understandable that teams with a cloud-first mindset would embrace innovation and new collaborative experiences to accomplish goals faster. However, some of the shadow IT application has weak or no security controls – resulting the opportunities for external collaborator accounts to be compromised or have mis-managed privileges.
With high-profile data breaches in the entertainment industry in recent headlines, Legendary Entertainment was concerned about its level of risk and exposure, especially since it has valuable intellectual property such as scripts and marketing strategy plans for film releases among its holdings. The requirement for stronger security has been a boardroom-level conversation at digital media companies since the Sony Pictures hack and other vendor supply chain and workflow hacks. Attacks now extend beyond data leaks and can have far reaching business disruptions across an entire supply chain.
By deploying MVISION Cloud Native Application Protection Platform (MVISION CNAPP), Legendary Entertainment addressed all of these challenges at once. This unique solution prioritizes alerts and defends against the latest cloud threats and vulnerabilities. MVISION CNAPP combines granular application and data context with cloud security posture management and cloud workload protection in a single-console solution.
MVISION CNAPP provides Legendary Entertainment with broad and deep visibility across its entire infrastructure. It discovers all their cloud assets, including compute resources, containers, and storage and provides continuous visibility into vulnerabilities and security posture for applications and workloads running across multiple clouds.
Thanks to MVISION CNAPP, Meacham’s team can write, apply, and enforce security policies in a consistent fashion for the entire cloud estate. As Meacham points out, policy is continually checked so his team can correct any misconfigurations, disable services, or remove escalated privileges until corrections are made in alignment with internal compliance rules. And in many cases, the remediation can be automated internally in MVISION CNAPP or through workflow initiations.
“MVISION CNAPP gives me manageability and security uniformity for all our cloud platforms so that I can elevate the level of security and make it consistent across the board. Now that I have visibility into all our cloud assets from a high level, I can look at how current controls and configurations compare to our best practices, industry best practices, and to the best practices of peers who are using the same product. Without MVISION CNAPP, management is one to one, whereas with MVISION CNAPP, it’s one to many,” explains Meacham.
The Cloud Security Posture Management (CSPM) component of MVISION CNAPP provides Legendary Entertainment with on-demand scanning, which looks at all services used in the public cloud and checks their security settings against internal benchmarks. “This gives us a security posture score and provides feedback on what we can do to bring ourselves back into compliance,” observes Meacham. “If someone changes a configuration, we get an alert right away. And if it’s not in alignment with policy, we can roll it back to the previous settings. MVISION CNAPP also helps us remediate policy exceptions by clearly stating the risks, instances impacted, and the necessary step by step actions needed for resolution.”
MVISION CNAPP also ensures that Legendary Entertainment’s developers operate in a secure environment by alerting the security team when their actions violate security policies or increase the risk of a data breach. This effectively puts a halt to Shadow IT.
“MVISION CNAPP helps me keep my system administrators and developers accountable for what they are doing. We can make sure that they are consistent in how they execute, deploy, and build things. Configuration policies, on-demand scans, and different types of checks in MVISION CNAPP can help force that compliance. I am able to keep tabs on my developers to make sure they are operating according to these guidelines in any platform,” remarks Meacham.
MVISION CNAPP reduces risk associated with operating in the cloud, enabling Legendary Entertainment to run mission-critical applications and develop blockbuster movies such as “The Dark Knight Rises” and “Dune” securely across a heterogenous multicloud environment. The solution also enables contextual entitlements so that users can be identified and assigned selective access to and permissions for applications and resources based on the security profile of the devices they are using at any given time.
Legendary Entertainment leverages MVISION CNAPP’s data loss prevention (DLP) capabilities to monitor activity in cloud data stores in order to help prevent data breaches. Unusual or suspicious activity or unauthorized movement of data transit is tracked and flagged immediately by leveraging built-in UEBA capabilities.
“If I see 2,000 files change in 30 seconds, that’s a huge red flag indicating ransomware or some other type of attack. The solution’s monitoring tool detects suspicious behavior and immediately brings that to our awareness. If we see something like that happening on multiple platforms, we know that immediate action is required. The UEBA capability is invaluable for identifying external collaborators who may have compromised accounts, which we find on a regular basis.”
If you are looking for a simple-to-manage, high-visibility solution to secure your multicloud environment against the latest threats and vulnerabilities such as ChaosDB, take a look at MVISION CNAPP. For more information, visit: https://www.mcafee.com/enterprise/en-us/solutions/mvision-cnapp.html.

The Robinhood trading platform recently disclosed a data breach that exposed the information of millions of its customers. News of the attack was released on Monday, November 8th along with word the hackers behind it had demanded an extortion payment from the company.
According to Robinhood’s disclosure, the attack occurred on November 3rd, which allowed an unauthorized party to obtain the following:
In addition, smaller groups of Robinhood customers had yet more information compromised. Around 310 people had their names, birth dates, and zip codes exposed in the breach. Another 10 customers had “more extensive account details revealed,” per Robinhood’s disclosure.
Robinhood went on to say, “We believe that no Social Security numbers, bank account numbers, or debit card numbers were exposed and that there has been no financial loss to any customers as a result of the incident.”
Robinhood further stated that the company contained the intrusion and that it promptly informed law enforcement of the extortion demand. Robinhood says that it is continuing to investigate the incident with the assistance of a security firm.
The company advised its customers to visit the Robinhood help center to receive the latest messages from the company, noting that they will never include a link to access an account in a security alert.
Any data breach that you and your information may have been involved in calls for a few quick security steps:
1. Log into your account and update your password with a new one that is strong and unique. Likewise, if you use the same or similar passwords across several accounts, change those as well. (A password manager that’s included with comprehensive online protection software can do that work for you.) Set up two-factor authentication if your account allows for it, as this will provide an extra layer of protection as well.
2. Review your statements for any strange activity—even the smallest of withdrawals or transactions could be the sign of a larger issue.
3. Report any suspected fraud to the company or institution involved. They typically have set policies and procedures in place to provide support.
If you believe that you’ve become a victim of identity theft, file a report with local law enforcement and the Federal Trade Commission (FTC). Law enforcement can provide you with a case number that you may need as part of the recovery process. Likewise, the FTC’s identity theft website provides excellent resources, including a recovery plan and a step-by-step walkthrough if you create an account with them.
For even more information, visit our blog that points out the signs of identity theft and the steps you can take should you find yourself victim.
Given that the breach apparently exposed some 5 million email addresses, there’s the risk that these may end up in the hands of bad actors who may use them for follow-on attacks.
Notable among them would be phishing attacks, where hackers could target Robinhood users with phony messages in an attempt to get affected users to reveal further account information. For example, hackers could potentially create bogus emails that appear to come from Robinhood and direct users to a malicious site that requests account information. As Robinhood stated, the company will never include a link to access an account in a security alert. Users should visit the Robinhood site directly for account information.
This breach could lead to other phishing attacks as well, ones that may or may not pose as communication from Robinhood. Some of these phishing attacks can be rather easy to spot, as they may include typos, poorly rendered logos, or spoofed web addresses. However, some sophisticated hackers can roll out rather polished phishing attacks that can closely resemble legitimate communications.
In all, people can avoid falling victim to phishing attacks by keeping the following in mind:
1. Only access your accounts directly from the official website of the company or financial institution involved. If you receive an email, message, or text alerting you of an issue, do not click any links provided in the communication. Go straight to the site yourself by typing in the proper address and view your account information there. Likewise, calling the customer support line posted on their official site is an option as well.
2. Use comprehensive online protection software that includes a spam filter. This can prevent phishing emails from reaching your inbox in the first place.
3. Get to know the signs of phishing emails. A common sign of a scam is an email, ad, message, or site that simply doesn’t look or read right. (Maybe the grammar is awkward or the logo is grainy or has the colors slightly wrong.) However, some of them can look quite convincing, yet there are still ways to spot an attempted phishing attack.
4. Beware of email attachments you aren’t expecting. This is always good form because hackers love to spike attachments with malware that’s designed to steal your personal information. Whether you get an unexpected attachment from a friend or business, follow up before opening it. That’s a quick way to find out if the attachment is legitimate or not.
For more info on phishing and how to steer clear of it, check out our blog on how to spot phishing attacks.
The unfortunate fact is that data breaches can and do happen. Many of the larger data breaches make the headlines, yet many more do not—such as the ones that hit small businesses, restaurants, and medical care providers. In the hands of hackers, the information spilled by these breaches can provide them with the building blocks to commit identity theft. As a result, keeping on top of your identity and personal information is a must.
The good news is that you have solid options to prevent them from harming you or at least greatly lessen their potential impact. With identity theft protection, even in the short-term, you can monitor emails addresses and usernames that are being used to breach other accounts. You can monitor dozens of different types of personal information and receive alerts to keep an eye out for misuse. Likewise, it can monitor your email addresses and bank accounts for signs of misuse or fraud, plus provide theft protection and support from a recovery specialist if identity theft, unfortunately, happens to you.
Along those same lines, news of a data breach offers all of us a moment to pause and take stock of just how protected we are. Above and beyond the steps covered above, comprehensive online protection can protect your devices from malware, phishing attacks, malicious websites, and other threats. More importantly, it protects you—your identity and privacy, particularly in times where breaches such as the one we’re talking about here occur with seeming regularity.

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

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