Microsoft has released its final monthly batch of security updates for 2022, fixing more than four dozen security holes in its various Windows operating systems and related software. The most pressing patches include a zero-day in a Windows feature that tries to flag malicious files from the Web, a critical bug in PowerShell, and a dangerous flaw in Windows 11 systems that was detailed publicly prior to this week’s Patch Tuesday.
The security updates include patches for Azure, Microsoft Edge, Office, SharePoint Server, SysInternals, and the .NET framework. Six of the update bundles earned Microsoft’s most dire “critical” rating, meaning they fix vulnerabilities that malware or malcontents can use to remotely commandeer an unpatched Windows system — with little to no interaction on the part of the user.
The bug already seeing exploitation is CVE-2022-44698, which allows attackers to bypass the Windows SmartScreen security feature. The vulnerability allows attackers to craft documents that won’t get tagged with Microsoft’s “Mark of the Web,” despite being downloaded from untrusted sites.
“This means no Protected View for Microsoft Office documents, making it easier to get users to do sketchy things like execute malicious macros, said Greg Wiseman, product manager at security firm Rapid7. This is the second Mark of the Web flaw Microsoft has patched in as many months; both were first publicly detailed over the past two months on Twitter by security researcher Will Dormann.
Publicly disclosed (but not actively exploited for now) is CVE-2022-44710, which is an elevation of privilege flaw in the DirectX graphics component of Windows 11.
Another notable critical bug is CVE-2022-41076, a remote code execution flaw in PowerShell — a key component of Windows that makes it easier to automate system tasks and configurations.
Kevin Breen at Immersive Labs said while Microsoft doesn’t share much detail about CVE-2022-41076 apart from the designation ‘Exploitation More Likely,’ they also note that successful exploitation requires an attacker to take additional actions to prepare the target environment.
“What actions are required is not clear; however, we do know that exploitation requires an authenticated user level of access,” Breen said. “This combination suggests that the exploit requires a social engineering element, and would likely be seen in initial infections using attacks like MalDocs or LNK files.”
Speaking of malicious documents, Trend Micro’s Zero Day Initiative highlights CVE-2022-44713, a spoofing vulnerability in Outlook for Mac.
“We don’t often highlight spoofing bugs, but anytime you’re dealing with a spoofing bug in an e-mail client, you should take notice,” ZDI’s Dustin Childs wrote. “This vulnerability could allow an attacker to appear as a trusted user when they should not be. Now combine this with the SmartScreen Mark of the Web bypass and it’s not hard to come up with a scenario where you receive an e-mail that appears to be from your boss with an attachment entitled “Executive_Compensation.xlsx”. There aren’t many who wouldn’t open that file in that scenario.”
Microsoft also released guidance on reports that certain software drivers certified by Microsoft’s Windows Hardware Developer Program were being used maliciously in post-exploitation activity.
Three different companies reported evidence that malicious hackers were using these signed malicious driver files to lay the groundwork for ransomware deployment inside victim organizations. One of those companies, Sophos, published a blog post Tuesday detailing how the activity was tied to the Russian ransomware group Cuba, which has extorted an estimated $60 million from victims since 2019.
Of course, not all scary and pressing security threats are Microsoft-based. Also on Tuesday, Apple released a bevy of security updates to iOS, iPadOS, macOS, tvOS and Safari, including a patch for a newly discovered zero-day vulnerability that could lead to remote code execution.
Anyone responsible for maintaining Fortinet or Citrix remote access products probably needs to update, as both are dealing with active attacks on just-patched flaws.
For a closer look at the patches released by Microsoft today (indexed by severity and other metrics) check out the always-useful Patch Tuesday roundup from the SANS Internet Storm Center. And it’s not a bad idea to hold off updating for a few days until Microsoft works out any kinks in the updates: AskWoody.com usually has the lowdown on any patches that may be causing problems for Windows users.
As always, please consider backing up your system or at least your important documents and data before applying system updates. And if you run into any problems with these updates, please drop a note about it here in the comments.
Happy National App Day! No, we don’t mean apps of the mozzarella stick and potato skin variety, but your mobile apps that let you order dinner, hail a taxi, stay connected to your friends, and entertain you for hours with silly videos. While they’re undoubtedly useful, mobile apps are also a weak spot in some people’s digital safety. Cybercriminals take every chance they get to trick people through all kinds of technology, and mobile apps are no exception.
To celebrate National App Day, here are a few tips to keep your mobile and your personally identifiable information (PII) safe.
Did you know that there are hundreds of apps on the Android and Apple app stores whose only aim is to steal your passwords? In 2022, Meta identified more than 400 fake apps disguised as various utilities that targeted users to weasel Facebook login and password combinations.1 Malicious apps also regularly masquerade as photo editors and wallpapers but their real purpose is to run malware in the background of the mobile device, such as this Squid Game app from 2021.
Little-known apps aren’t the only ones you have to be wary of either. The biggest companies are also falling to cybercrime. For instance, more details recently came to light about a breach at Uber that leaked the PII of 57 million users. Plus, the popular mobile payment service, Cash App had the personal details of 8.3 million current and former users leaked.2
To keep your cellphone free of malicious software and your PII and password secure, take these five mobile security tips with you into the new year.
The new year is as good a time as any to unload any unnecessary baggage, emotional, literal, or in this case, digital. Go through your phone and delete the apps you haven’t used in the last six months. Make sure to completely delete your account with that app and not just hide it from your homepage. The smaller your digital footprint, the less at risk your PII is of being compromised in a breach.
Before you download any new app, it’s a good idea to conduct some background research on it. How many detailed reviews does it have? Who is the app developer? A phony app usually reveals itself through its lack of reviews. Consider apps with less than 50 reviews fishy. Skim the reviews for specific details and typos. If it’s lacking in detail but brimming with typos and grammatical mistakes, it could signal a fake. This research should take about five minutes, so don’t worry; it shouldn’t be too much of an inconvenience, and that time will be well spent.
Just like it’s a good idea to keep on top of global news, set up news alerts for cybersecurity breaches. If a company falls to a cybercriminal, the alert will give you the valuable time you need to act quickly to either delete your account or change your password.
For every online account, it is essential to create a unique password or passphrase. That way, if you do get hacked through an app or get tricked by a fake one, you don’t have to worry about cybercriminals using that password to walk into your other accounts. Password managers are an excellent way to keep all your passwords secure and free up your brain space for things other than dozens of passwords.
When you sign up for a new app, you can expect to give it a username, a password, and maybe your first name; however, if it has optional fields for your full birthday or your address, consider leaving those blank. The less information the company has about you, the less that can end up in cybercriminals’ hands if the app is breached.
The first step to better cyber habits is arming yourself with the knowledge of the threats that are out there. The best advice here is to slow down, observe and think about your next move every time you download a new app. The signs of a fake are usually not difficult to spot. Then, once you’re confident in its legitimacy, limit the amount of PII you share with it. In this digital world we live in, consider everyone susceptible to a breach.
To give you peace of mind, supplement your great habits with a tool, like McAfee+ Ultimate, that will cover all your bases and be your partner to live your best private life online.

Watch ThreatWise TV: Explorations in the spam folder
The spam folder: that dark and disregarded corner of every email account, full of too-good-to-be-true offers, unexpected shipments, and supposedly free giveaways.
You’re right to ignore this folder; few good things come from exploring it. But every once in a while one of these misleading, and sometimes malicious, emails manages to evade the filters that normally siphon them off, landing them in your inbox instead.
Fortunately, it’s easy enough to spot these emails if you know what to look for. We’ve investigated this folder once before, showcasing a variety of scams. With the holiday season in full swing, we thought this would be a good time to revisit how scammers are trying to trick unsuspecting users.
The holiday season is traditionally a time when this type of activity increases, and this year is no different. According to research published by credit reporting agency TransUnion, the average daily number of suspected digital fraud attempts was up 82 percent globally between Thanksgiving and Cyber Monday (Nov 24–Nov 28) compared to the rest of the year (Jan 1–Nov 23) and 127 percent higher for transactions originating in the US.
This level of activity makes it all the more important to be aware of these scams. With that in mind, let’s dive into the spam folder to get a picture of the types of campaigns currently circulating.
While much of the spam circulating is innocuous, many emails are phishing attempts, and some are indeed malicious. To explore these scams, we used a dedicated computer, segmented from the rest of the network, and leveraged Cisco Secure Malware Analytics to safely open the emails before clicking on links or opening attachments. The point being, we do not recommend doing this at home.
By far, the largest category of spam we saw were surveys scams. According to these emails, if you fill out a simple survey you’ll receive “exclusive offers” such as gift cards, smartphones, smart watches, power drills, or even pots and pans.
There are even some campaigns that specifically target the holiday shopping season.
Clicking the links in these emails takes the recipient to sites where they are asked to fill out a survey.
These pages often include fake testimonials that say how easy the survey is and what they did with their free gift.
The surveys are straightforward, comprising 10-20 simple questions that cover demographic information and shopping habits.
After the survey is completed, these sites offer the choice of a handful of rewards. All the recipient must do is pay for shipping. They are then brought to a page where they can fill out shipping and payment information, and the reward is supposedly shipped.
However, the attempts to make payment often appear to fail, or the recipient is informed that the prize is no longer available.
An unsuspecting user may simply give up at this point, disappointed that they won’t be getting their free gift. What they may not be aware of, is that they have just given their credit card details away in a phishing scam.
In their 2021 Internet Crime Report, the Internet Crime Complaint Center (IC3) said that Non-Payment / Non-Delivery scams such as these led to more than $337 million in losses, up from $265 million in 2020. Credit card fraud amounted to $172 million in 2021 and has been climbing continuously at a conservative rate of 15-20 percent since 2019.
According to Cisco Umbrella, many of the sites asking for credit card details are known phishing sites, or worse, host malware.
Another topic that we covered the last time we explored these types of scams was package delivery spam. These continue to circulate today. There are a variety of shipping companies impersonated in these campaigns, and some generic ones as well.
Many of these campaigns claim that a package could not be delivered. If the recipient clicks on a link in an email, they’re brought to a web page that explains that there are outstanding delivery fees that need to be paid.
The recipient is further enticed by suggestions that the package contains a big-ticket item, such as an iPhone or iPad Pro. All the recipient is required to do is enter their credit card details to cover the shipping.
While no outright malicious activity was detected while examining these emails in Secure Malware Analytics, several suspicious behaviors were flagged. Chances are the bad actors behind these campaigns are phishing for credit card details.
Sometimes the simplest approaches can work just as well as the flashiest. This certainly holds true with spam campaigns, given the prominence of plain-text messages.
The topics covered in such emails run the gamut, including medical cures, 419 scams, romance and dating, pharmaceuticals, weight loss, and many of the scam types we’ve already covered. Many of these link to phishing sites, though some attempt to establish a dialog with the recipient, tricking them into sending the scammers money.
The IC3 report says that victims of confidence fraud and romance scams lost $956 million collectively, which is up from $600 million in 2020. Healthcare fraud, such as the miracle pills and prescriptions scams, resulted in $7 million in losses in 2021, but nearly $30 million in 2020. While these types of scams seem generic and easily spotted, they still work, and so it’s important to be aware and avoid them.
Many emails hitting the spam box attempt to trick users of various services into believing that there is a problem with their account. The problems cover all sorts of services, including streaming platforms, email providers, antivirus subscriptions, and even public records.
If the links are clicked, the recipient is presented with landing pages that mimic the respective services. Any details that are entered will likely be phished, leading to account takeover and/or access to personal records. However, some domains encountered in these cases may do more than just steal information, they could deliver malware too.
Another frequently encountered scam surrounds billing. Many of these appear to be unexpected bills for services the recipient never purchased.
These emails include attachments that are designed to look like official invoices. Interestingly, most of the attachments that we looked at this time were harmless. The goal is to get the recipient to call what appears to be a toll-free number.
While we haven’t called any of these numbers, the experience usually unfolds like a standard customer service call. In the end the “agents” simply claim the charges—which never existed in the first place—have been removed. Meanwhile the scammers steal any personal or financial information provided during the call.
While most billing scams we encountered played out as described above, a few did indeed contain malware.
In this example, the email appears to come from an internet service provider, informing us that our monthly bill is ready.
An invoice appears to be attached, stored within a .zip file. If the recipient opens it and double clicks the file within, a command prompt appears.
This may seem unusual to the recipient, especially since no invoice appears, but by this point it’s too late. The file contains a script that launches PowerShell and attempts to download a remote file.
While the remote file was no longer available at the time of analysis, there is a high likelihood it was malicious. But even though we were unable to determine its contents, Secure Malware Analytics flagged the script execution as malicious.
Knowing about prevalent scams, especially during the holiday season, is a first step in guarding against them. Granted the bad actors who distribute these spam campaigns do everything they can to make their scams look legitimate.
Fortunately, there are several things that you can do to identify scams and defend against them:
But even the best of us can be fooled, and when overseeing a large operation it’s more a matter of when, rather than if, someone clicks on the wrong link. There are elements of the Cisco Secure portfolio that can help for when the inevitable happens.
Cisco Secure Malware Analytics is the malware analysis and malware threat intelligence engine behind all products across the Cisco Security Architecture. The system delivers enhanced, in-depth, advanced malware analysis and context-rich intelligence to help better understand and fight malware within your environments.

This time of year, the air not only gets chillier but a bit cheerier for everyone … including online scammers. Holiday scams are a quick way to make a buck, and cybercriminals employ several holiday-themed schemes to weasel money and personally identifiable information (PII) from gift givers.
Here are three common holiday scams to watch out for this year, plus a few tips to help you stay safe online.
Gift cards are a standby present for the people on your list who are difficult to buy for or for people you don’t know too well but want to get them a small something. Whether the gift card is worth $5 or $500, an online scammer can steal the entire value through two techniques: a brute force attack or phishing. Known as gift card cracking, cybercriminals can take wild guesses at gift card codes and cash in the value for themselves by methodically guessing strings of numbers and letters and crossing their fingers for a match. Cybercriminals will also employ phishing emails, texts or social media direct messages to trick people into divulging gift card information.
To avoid gift card cracking, encourage gift receivers to redeem their gift card quickly to shorten the amount of time a scammer has to guess the code correctly. Or, you could opt for a paper gift certificate from a small business that doesn’t require online redeeming at all. To avoid gift card phishing scams, do not engage with any type of correspondence that claims they can double the value of your gift card or claims that there’s a problem with it. Be instantly on alert if anyone asks for the activation code. If the gift card-issuing business really needs to replace your purchase, they’ll issue you a new code. They’ll never ask for your existing one.
Are you a procrastinator? Watch out for last-minute shopping scams that are targeted at people who leave their gift buying until deep in December. As with anything else, if it’s too good to be true, it probably is. Shopping scams often take the form of phishing emails where criminals impersonate a well-known merchant or shipping company.
While sales often have a quick timeline, don’t let that short timeline pressure you into making an impulsive decision. Phishers rely on people’s excitement or inattention to trick them into giving up their credit card or banking information. Phishing emails, when you take the time to inspect them, are usually easy to spot. The logos are often blurry, there are often typos and grammar mistakes, and the tone of the message will seem “off.” Either it will sound very formal and impersonalized or it will sound very informal and seem pushy.
To protect your finances during the holiday season, consider putting a lock on your credit. This is easy to do with McAfee credit lock. You can still use your credit card and shop as you normally would. A credit lock is useful because, in case a criminal gets ahold of your PII, they won’t be able to open lines of credit in your name. This protects your credit score, which is essential to keep in good standing if you hope to buy a house or take out a loan anytime soon.
Just because a “company” has an ad on Facebook or Instagram doesn’t mean that it’s a legitimate establishment. Before buying from an online store you’ve never heard of, do some background research on it and read customer reviews to make sure that it’s real and will deliver you a quality product.
Take note of the online store’s URL before entering it. (You can preview the link by hovering over it with your cursor.) If the URL is a string of letters and numbers, it could be a malware site in disguise. One way to alert you to suspicious sites is McAfee Web Protection. Web Protection color codes links to identify potential malware and phishing sites and alert you to steer clear.
Your mind is already drawn in a bunch of different directions this holiday season (cooking, traveling, shopping, wrapping, tidying) so give yourself a respite from worrying about the safety of your identity and finances. McAfee+ Ultimate includes a VPN, Web Protection, credit lock, antivirus and more to cover all your bases to keep your devices and your PII safe.
The post ‘Tis the Season for Holiday Scams appeared first on McAfee Blog.
Even with the holidays in full swing, scammers won’t let up. In fact, it’s high time for some of their nastiest cons as people travel, donate to charities, and simply try to enjoy their time with friends and family.
Unfortunate as it is, scammers see this time of year as a tremendous opportunity to profit. While people focus giving to others, they focus on taking, propping up all manner of scams that use the holidays as a disguise. So as people move quickly about their day, perhaps with a touch of holiday stress in the mix, they hope to catch people off their guard with scams that wrap themselves in holiday trappings.
Yet once you know what to look for, they’re relatively easy to spot. The same scams roll out every year, sometimes changing in appearance yet remaining the same in substance. With a sharp eye, you can steer clear of them.
With Black Friday and Cyber Monday in the books, we can look forward to what’s next—a wave of post-holiday sales events that will likewise draw in millions of online shoppers. And just like those other big shopping days, bad actors will roll out a host of scams aimed at unsuspecting shoppers. Shopping scams take on several forms, which makes this a topic unto itself, one that we cover thoroughly in our Black Friday & Cyber Monday shopping scams blog. It’s worth a read if you haven’t done so already, as digs into the details of these scams and shows how you can avoid them.
However, the high-level advice for avoiding shopping scams is this: keep your eyes open. Deals that look too good to be true likely are, and shopping with retailers you haven’t heard of before requires a little bit of research to determine if their track record is clean. In the U.S., you can turn to the Better Business Bureau (BBB) for help with a listing of retailers you can search simply by typing in their names. You can also use https://whois.domaintools.com to look up the web address of the shopping site you want to research. There you can see its history and see when it was registered. A site that was registered only recently may be far less reputable than one that’s been registered for some time.
Plenty of new tech makes its way into our homes during the holiday season. And some of that tech can be a little challenging to set up. Be careful when you search for help online. Many scammers will establish phony tech support sites that aim to steal funds and credit card information. Go directly to the product manufacturer for help. Often, manufacturers will offer free support as part of the product warranty, so if you see a site advertising support for a fee, that could be a sign of a scam.
Likewise, scammers will reach out to you themselves. Whether through links from unsolicited emails, pop-up ads from risky sites, or by spammy phone calls, these scammers will pose as tech support from reputable brands. From there, they’ll falsely inform you that there’s something urgently wrong with your device and that you need to get it fixed right now—for a fee. Ignore these messages and don’t click on any links or attachments. Again, if you have concerns about your device, contact the manufacturer directly.
With the holidays comes travel, along with all the online booking and ticketing involved. Scammers will do their part to cash in here as well. Travel scams may include bogus emails that pose as reputable travel sites telling you something’s wrong with your booking. Clicking a link takes you to a similarly bogus site that asks for your credit card information to update the booking—which then passes it along to the scammer so they can rack up charges in your name. Other travel scams involve ads for cut-rate lodging, tours, airfare, and the like, all of which are served up on a phony website that only exists to steal credit card numbers and other personal information.
Some of these scams can look quite genuine, even though they’re not. They’ll use cleverly disguised web addresses that look legitimate, but aren’t, so don’t click any links. If you receive notice about an issue with your holiday travel, contact the company directly to follow up. Also, be wary of ads with unusually deep discounts or that promise availability in an otherwise busy season or time. These could be scams, so stick with reputable booking sites or with the websites maintained by hotels and travel providers themselves.
Donations to an organization or cause that’s close to someone’s heart make for a great holiday gift, just as they offer you a way to give back during the holiday season. And you guessed it, scammers will take advantage of this too. They’ll set up phony charities and apply tactics that pressure you into giving. As with so many scams out there, any time an email, text, direct message, or site urges you into immediate action—take pause. Research the charity. See how long they’ve been in operation, how they put their funds to work, and who truly benefits from them.
Likewise, note that there some charities pass along more money to their beneficiaries than others. As a general rule of thumb, most reputable organizations only keep 25% or less of their funds for operations, while some less-than-reputable organizations keep up to 95% of funds, leaving only 5% for advancing the cause they advocate. In the U.S., the Federal Trade Commission (FTC) has a site full of resources so that you can make your donation truly count. Resources like Charity Watch and Charity Navigator, along with the BBB’s Wise Giving Alliance can also help you identify the best charities.
The holidays also mean a flight of big-time sporting events, and with the advent of online betting in many regions scammers want to cash in. This scam works quite like shopping scams, where bad actors will set up online betting sites that look legitimate. They’ll take your bet, but if you win, they won’t pay out. Per the U.S. Better Business Bureau (BBB), the scam plays out like this:
“You place a bet, and, at first, everything seems normal. But as soon as you try to cash out your winnings, you find you can’t withdraw a cent. Scammers will make up various excuses. For example, they may claim technical issues or insist on additional identity verification. In other cases, they may require you to deposit even more money before you can withdraw your winnings. Whatever you do, you’ll never be able to get your money off the site. And any personal information you shared is now in the hands of scam artists.”
You can avoid these sites rather easily. Stick with the online betting sites that are approved by your regional gambling commission. Even so, be sure to read the fine print on any promo offers that these sites advertise because even legitimate betting sites can freeze accounts and the funds associated with them based on their terms and conditions.
A complete suite of online protection software, such as McAfee+ Ultimate can offer layers of extra security. In addition to more private and secure time online with a VPN, identity monitoring, and password management, it includes web browser protection that can block malicious and suspicious links that could lead you down the road to malware or a phishing scam—which antivirus protection can’t do alone. Additionally, we offer $1M identity theft coverage and support from a recovery pro, just in case.
And because scammers use personal information such as email addresses and cell phone numbers to wage their attacks, other features like our Personal Data Cleanup service can scan high-risk data broker sites for your personal information and then help you remove it, which can help reduce spam, phishing attacks, and deny bad actors the information they need to commit identity theft.
That’s why they enjoy the holidays so much. With all our giving, travel, and charity in play, it’s prime time for their scams. Yet a little insight into their cons, along with some knowledge as to how they play out, you can avoid them.
Remember that they’re playing into the hustle and bustle of the season and that they’re counting on you to lower your guard more than you might during other times of the year. Keep an eye open for the signs, do a little research when it’s called for, and stick with reputable stores, charities, and online services. With a thoughtful pause and a second look, you can spare yourself the grief of a scam and fully enjoy your holidays.
The post Unwrapping Some of the Holiday Season’s Biggest Scams appeared first on McAfee Blog.
Let’s face it: Having “2022 election” in the headline above is probably the only reason anyone might read this story today. Still, while most of us here in the United States are anxiously awaiting the results of how well we’ve patched our Democracy, it seems fitting that Microsoft Corp. today released gobs of security patches for its ubiquitous Windows operating systems. November’s patch batch includes fixes for a whopping six zero-day security vulnerabilities that miscreants and malware are already exploiting in the wild.
Probably the scariest of the zero-day flaws is CVE-2022-41128, a “critical” weakness in the Windows scripting languages that could be used to foist malicious software on vulnerable users who do nothing more than browse to a hacked or malicious site that exploits the weakness. Microsoft credits Google with reporting the vulnerability, which earned a CVSS score of 8.8.
CVE-2022-41073 is a zero-day flaw in the Windows Print Spooler, a Windows component that Microsoft has patched mightily over the past year. Kevin Breen, director of cyber threat research at Immersive Labs, noted that the print spooler has been a popular target for vulnerabilities in the last 12 months, with this marking the 9th patch.
The third zero-day Microsoft patched this month is CVE-2022-41125, which is an “elevation of privilege” vulnerability in the Windows Cryptography API: Next Generation (CNG) Key Isolation Service, a service for isolating private keys. Satnam Narang, senior staff research engineer at Tenable, said exploitation of this vulnerability could grant an attacker SYSTEM privileges.
The fourth zero-day, CVE-2022-41091, was previously disclosed and widely reported on in October. It is a Security Feature Bypass of “Windows Mark of the Web” – a mechanism meant to flag files that have come from an untrusted source.
The other two zero-day bugs Microsoft patched this month were for vulnerabilities being exploited in Exchange Server. News that these two Exchange flaws were being exploited in the wild surfaced in late September 2022, and many were surprised when Microsoft let October’s Patch Tuesday sail by without issuing official patches for them (the company instead issued mitigation instructions that it was forced to revise multiple times). Today’s patch batch addresses both issues.
Greg Wiseman, product manager at Rapid7, said the Exchange flaw CVE-2022-41040 is a “critical” elevation of privilege vulnerability, and CVE-2022-41082 is considered Important, allowing Remote Code Execution (RCE) when PowerShell is accessible to the attacker.
“Both vulnerabilities have been exploited in the wild,” Wiseman said. “Four other CVEs affecting Exchange Server have also been addressed this month. Three are rated as Important, and CVE-2022-41080 is another privilege escalation vulnerability considered Critical. Customers are advised to update their Exchange Server systems immediately, regardless of whether any previously recommended mitigation steps have been applied. The mitigation rules are no longer recommended once systems have been patched.”
Adobe usually issues security updates for its products on Patch Tuesday, but it did not this month. For a closer look at the patches released by Microsoft today and indexed by severity and other metrics, check out the always-useful Patch Tuesday roundup from the SANS Internet Storm Center. And it’s not a bad idea to hold off updating for a few days until Microsoft works out any kinks in the updates: AskWoody.com usually has the lowdown on any patches that may be causing problems for Windows users.
As always, please consider backing up your system or at least your important documents and data before applying system updates. And if you run into any problems with these updates, please drop a note about it here in the comments.
On Black Friday and Cyber Monday, the deals roll out. So do some of the worst Black Friday and Cyber Monday scams.
Hackers, scammers, and thieves look to cash in this time of year by blending in with the holiday rush, spinning up their own fake shipping notices, phony deals, and even bogus charities that look legitimate at first glance, yet are anything but. Instead, they may be loaded with malware, point you to phishing sites that steal your personal info, or they may simply rip you off.
Classically, many online scams play on emotions by creating a sense of urgency or even fear. And for the holidays, you can throw stress into that mix as well—the stress of time, money, or even the pressure of finding that hard-to-get gift that seems to be out of stock everywhere. The bad actors out there will tailor their attacks around these feelings, hoping that they’ll catch you with your guard down during this busy time of year.
So while knowing how to spot a great gift at a great price is solid skill to have this time of year, so is the ability to spot a scam. Let’s look at some of the worst ones out there, along with what you can do to steer clear of them.
Come this time of year, keeping tabs on all the packages you have in transit can get tricky. You may have an armload of them enroute at any given time, and scammers will look to slip into this mix with phony order confirmations sent to your mailbox or your phone by text. Packed with either an email attachment or a link to a bogus website, they’ll try to get you to download malware or visit a site that attempts to steal your identity.
These messages can look quite legit, so the best way to keep track of your orders is on the sites where you purchased them. Go directly to those sites rather than clicking on any links or attachments you get.
This scam plays out much like the fake order scam, yet in this case the crooks will send a phony package tracking notification, again either as a link or as an attachment. For starters, legitimate retailers won’t send tracking numbers in an attached file. If you see anything like that, it’s surely a scam designed to inject malware onto your device. In the case of a link, the scammers aim to send you to a site that will steal your personal info, just like in the case above.
Once again, the best way to track your packages is to go to the source. Visit the online store where you made your purchase, open your current orders, and get your package tracking information from there.
A classic scammer move is to “typosquat” phony email addresses and URLs that look awfully close to legitimate addresses of legitimate companies and retailers. So close that you may overlook them. They often appear in phishing emails and instead of leading you to a great deal, these can in fact link you to scam sites that can then lift your login credentials, payment info, or even funds should you try to place an order through them.
You can avoid these sites by going to the retailer’s site directly. Be skeptical of any links you receive by email, text, or direct message—it’s best to go to the site yourself by manually typing in the legitimate address yourself and look for the deal there.
At the heart of holiday shopping is scarcity. And scarcity is something scammers love. There’s always some super-popular holiday item that’s tough to find, and scammers will spin up phony websites and offers around those items to lure you in. They may use the typosquatting technique mentioned above to pose as a legitimate retailer, or they may set up a site with their own branding to look legitimate on their own (or at least try). Either way, these scams can hurt you in a couple of ways—one, you’ll pay for the goods and never receive them; and two, the scammers will now have your payment info and address, which they can use to commit further fraud.
If the pricing, availability, or delivery time all look too good to be true for the item in question, it may be a scam designed to harvest your personal info and accounts. Use caution here before you click. If you’re unsure about a product or retailer, read reviews from trusted websites to help see if it’s legitimate. (The Better Business Bureau is a great place to start—more on that in moment.)
In the season of giving, donating to charities in your name or in the name of others makes for a popular holiday gesture. Scammers know this too and will set up phony charities to cash in. Some indications that a phony charity has reached you include an urgent pitch that asks you to “act now.” A proper charity will certainly make their case for a donation, yet they won’t pressure you into it. Moreover, phony charities will outright ask for payment in the form of gift cards, wire transfers (like Western Union), money orders, or even cryptocurrency—because once those funds are sent, they’re nearly impossible to reclaim when you find out you’ve been scammed.
There are plenty of ways to make donations to legitimate charities, and the U.S. Federal Trade Commission (FTC) has a site full of resources so that you can make your donation truly count.
Some of it takes an eagle eye that can spot these scams as they pop up in your inbox, texts, social media feed, and so on. Yet you have further ways you can keep safe while shopping on Black Friday, Cyber Monday, and any time.
This is a great one to start with. Directly typing in the correct address for online stores and retailers is a prime way to avoid scammers online. In the case of retailers that you don’t know much about, the U.S. Better Business Bureau (BBB) asks shoppers to do their research and make sure that retailer has a good reputation. The BBB makes that easier with a listing of retailers you can search simply by typing in their name.
Secure websites begin their address with “https,” not just “http.” That extra “s” in stands for “secure,” which means that it uses a secure protocol for transmitting sensitive info like passwords, credit card numbers, and the like over the internet. It often appears as a little padlock icon in the address bar of your browser, so double-check for that. If you don’t see that it’s secure, it’s best to avoid making purchases on that website.
In the U.S., the Fair Credit Billing Act offers the public protection against fraudulent charges on credit cards, where citizens can dispute charges over $50 for goods and services that were never delivered or otherwise billed incorrectly. Note that many credit card companies have their own policies that improve upon the Fair Credit Billing Act as well. However, debit cards aren’t afforded the same protection under the Act. Avoid using a debit card while shopping online and use your credit card instead.
Two-factor authentication is an extra layer of defense on top of your username and password. It adds in the use of a special one-time-use code to access your account, usually sent to you via email or to your phone by text or a phone call. In all, it combines something you know, like your password, with something you have, like your smartphone. Together, that makes it tougher for a crook to hack your account. If any of your accounts support two-factor authentication, the few extra seconds it takes to set up is more than worth the big boost in protection you’ll get.
Public Wi-Fi in coffee shops and other public locations can expose your private surfing to prying eyes because those networks are open to all. Using a virtual private network (VPN) encrypts your browsing, shopping, and other internet traffic, thus making it secure from attempts at intercepting your data on public Wi-Fi, such as your passwords and credit card numbers.
What’s more, a VPN masks your whereabouts and your IP address, plus uses encryption that helps keep your activities private. As a result, companies and data brokers can potentially learn far less about you, your shopping, your travels, your habits, and any other information that they could possibly collect and otherwise profit from.
Yes, it’s true. Your information gets collected, bought, and solid online. In fact, personal information fuels a global data trading economy estimated at $200 billion U.S. dollars a year. Run by data brokers that keep hundreds and even thousands of data points on billions of people, these sites gather, analyze, buy, and sell this information to other companies as well as to advertisers. Likewise, these data brokers may sell this information to bad actors, such as hackers, spammers, and identity thieves who would twist this information for their own purposes.
Getting your info removed from these sites can seem like a daunting task. (Where do I start, and just how many of these sites are out there?) Our Personal Data Cleanup can help by regularly scanning these high-risk data broker sites for info like your home address, date of birth, and names of relatives. It identifies which sites are selling your data, and depending on your plan, automatically requests removal.
Another place where personal information is bought and sold, stored, and exchanged is the dark web. The problem is that it’s particularly difficult for you to determine what, if any, of your info is on the dark web, stashed away in places where hackers and thieves can get their hands on it. Identity monitoring can help. McAfee’s identity monitoring helps you keep your personal info safe by alerting you if your data is found on the dark web, an average of 10 months before our competitors.
Monitored info can range anywhere from bank account and credit card numbers to your email addresses and government ID number, depending on your location. If your information gets spotted, you’ll get an alert, along with steps you can take to minimize or even prevent damage if the information hasn’t already been put to illegal use.
Identity protection through McAfee takes identity monitoring a step further by offering, depending on your location and plan, identity theft coverage for financial losses and expenses due to identity theft, in addition to hands-on help from a recovery professional to help restore your identity—all in addition to the identity monitoring called out above, again depending on your location and plan.
Keeping an eye on your bills and statements as they come in can help you spot unusual activity on your accounts. A credit monitoring service can do that one better by keeping daily tabs on your credit report. While you can do this manually, there are limitations. First, it involves logging into each bureau and doing some digging of your own. Second, there are limitations as to how many free credit reports you can pull each year. A service does that for you and without impacting your credit score.
Depending on your location and plan, McAfee’s credit monitoring allows you to look after your credit score and the accounts within it to see fluctuations and help you identify unusual activity, all in one place, checking daily for signs of identity theft.
A complete suite of online protection software like McAfee+ can offer layers of extra security while you shop. In addition to the VPN, identity, credit monitoring, and other features mentioned above, it includes web browser protection that can block malicious and suspicious links that could lead you down the road to malware or a phishing scam—along with a password manager that can create strong, unique passwords and store them securely as well. Taken together, McAfee+ offers all-in-one online protection for your identity, privacy, and security that can keep you far safer when you shop online—and as you spend your time online in general.
Even if you take the proper precautions the unexpected can happen. Whether it’s a scam, an identity crime, or flat-out theft, there are steps you can take right away to help minimize the damage.
The first bit of advice is to take a deep breath and get right to work on recovery. From there, you can take the following steps:
Whether you spot a curious charge on your bank statement, discover potentially a fraudulent account when you check credit report, or when you get an alert from your monitoring service, let the bank or organization involved know you suspect fraud or theft. With a visit to their website, you can track down the appropriate number to call and get the investigation process started.
Some businesses will require you to file a local police report and acquire a case number to complete your claim. Beyond that, filing a report is a good idea in itself. Identity theft is still theft and reporting it provides an official record of the incident. Should your case of identity theft lead to someone impersonating you or committing a crime in your name, filing a police report right away can help clear your name down the road. Be sure to save any evidence you have, like statements or documents that are associated with the theft. They can help clean up your record as well.
In the U.S., the identity theft website from the Federal Trade Commission (FTC) is a fantastic resource should you find yourself in need. In addition to keeping records of the theft, the FTC can provide you with a step-by-step recovery plan—and even walk you through the process if you create an account with them. Additionally, reporting theft to the FTC can prove helpful if debtors come knocking to collect on any bogus charges in your name. With a copy of your report, you can ask debtors to stop.
An instance of identity fraud or theft, suspected or otherwise, is a good time to review your options for a credit freeze or lock. As mentioned earlier, see what the credit bureaus in your region offer, along with the terms and conditions of each. With the right decision, a freeze or lock can help minimize and prevent further harm.
Strongly consider using a monitoring service like the one we described earlier to help you continue to keep tabs on your identity. The unfortunate fact of identity theft and fraud is that it can mark the start of a long, drawn-out affair. One instance of theft can possibly lead to another, so even what may appear to be an isolated bad charge on your credit card calls for keeping an eye on your identity all around. Many of the tools you would use up to this point still apply, such as checking up on your credit reports, maintaining fraud alerts as needed, and reviewing your accounts closely—along with utilizing an identity monitoring service.
A recovery service can help you clean up your credit in the wake of fraud or theft, all by working on your behalf. Given the time, money, and stress that can come along with setting your financial record straight, leaning on the expertise of a professional can provide you with much-needed relief on several counts.
Just as it’s always been, hackers, scammers, and thieves want to ruin a good thing. In this case, it’s your spirit of giving and sharing in the holiday season. Yet with this list of top scams and ways you can avoid them, you can keep bad actors like them at bay. Remember, they’re counting on you to be in a hurry this time of year, and maybe a bit stressed and a little disorganized to boot. Take your time while shopping out there and keep an eye out for their tricks. That extra moment can save you far more time and money than you may think.

Microsoft today released updates to fix at least 85 security holes in its Windows operating systems and related software, including a new zero-day vulnerability in all supported versions of Windows that is being actively exploited. However, noticeably absent from this month’s Patch Tuesday are any updates to address a pair of zero-day flaws being exploited this past month in Microsoft Exchange Server.
The new zero-day flaw– CVE-2022-41033 — is an “elevation of privilege” bug in the Windows COM+ event service, which provides system notifications when users logon or logoff. Microsoft says the flaw is being actively exploited, and that it was reported by an anonymous individual.
“Despite its relatively low score in comparison to other vulnerabilities patched today, this one should be at the top of everyone’s list to quickly patch,” said Kevin Breen, director of cyber threat research at Immersive Labs. “This specific vulnerability is a local privilege escalation, which means that an attacker would already need to have code execution on a host to use this exploit. Privilege escalation vulnerabilities are a common occurrence in almost every security compromise. Attackers will seek to gain SYSTEM or domain-level access in order to disable security tools, grab credentials with tools like Mimkatz and move laterally across the network.
Indeed, Satnam Narang, senior staff research engineer at Tenable, notes that almost half of the security flaws Microsoft patched this week are elevation of privilege bugs.
Some privilege escalation bugs can be particularly scary. One example is CVE-2022-37968, which affects organizations running Kubernetes clusters on Azure and earned a CVSS score of 10.0 — the most severe score possible.
Microsoft says that to exploit this vulnerability an attacker would need to know the randomly generated DNS endpoint for an Azure Arc-enabled Kubernetes cluster. But that may not be such a tall order, says Breen, who notes that a number of free and commercial DNS discovery services now make it easy to find this information on potential targets.
Late last month, Microsoft acknowledged that attackers were exploiting two previously unknown vulnerabilities in Exchange Server. Paired together, the two flaws are known as “ProxyNotShell” and they can be chained to allow remote code execution on Exchange Server systems.
Microsoft said it was expediting work on official patches for the Exchange bugs, and it urged affected customers to enable certain settings to mitigate the threat from the attacks. However, those mitigation steps were soon shown to be ineffective, and Microsoft has been adjusting them on a daily basis nearly each day since then.
The lack of Exchange patches leaves a lot of Microsoft customers exposed. Security firm Rapid7 said that as of early September 2022 the company observed more than 190,000 potentially vulnerable instances of Exchange Server exposed to the Internet.
“While Microsoft confirmed the zero-days and issued guidance faster than they have in the past, there are still no patches nearly two weeks out from initial disclosure,” said Caitlin Condon, senior manager of vulnerability research at Rapid7. “Despite high hopes that today’s Patch Tuesday release would contain fixes for the vulnerabilities, Exchange Server is conspicuously missing from the initial list of October 2022 security updates. Microsoft’s recommended rule for blocking known attack patterns has been bypassed multiple times, emphasizing the necessity of a true fix.”
Adobe also released security updates to fix 29 vulnerabilities across a variety of products, including Acrobat and Reader, ColdFusion, Commerce and Magento. Adobe said it is not aware of active attacks against any of these flaws.
For a closer look at the patches released by Microsoft today and indexed by severity and other metrics, check out the always-useful Patch Tuesday roundup from the SANS Internet Storm Center. And it’s not a bad idea to hold off updating for a few days until Microsoft works out any kinks in the updates: AskWoody.com usually has the lowdown on any patches that may be causing problems for Windows users.
As always, please consider backing up your system or at least your important documents and data before applying system updates. And if you run into any problems with these updates, please drop a note about it here in the comments.
Microsoft Corp. is investigating reports that attackers are exploiting two previously unknown vulnerabilities in Exchange Server, a technology many organizations rely on to send and receive email. Microsoft says it is expediting work on software patches to plug the security holes. In the meantime, it is urging a subset of Exchange customers to enable a setting that could help mitigate ongoing attacks.
In customer guidance released Thursday, Microsoft said it is investigating two reported zero-day flaws affecting Microsoft Exchange Server 2013, 2016, and 2019. CVE-2022-41040, is a Server-Side Request Forgery (SSRF) vulnerability that can enable an authenticated attacker to remotely trigger the second zero-day vulnerability — CVE-2022-41082 — which allows remote code execution (RCE) when PowerShell is accessible to the attacker.
Microsoft said Exchange Online has detections and mitigation in place to protect customers. Customers using on-premises Microsoft Exchange servers are urged to review the mitigations suggested in the security advisory, which Microsoft says should block the known attack patterns.
Vietnamese security firm GTSC on Thursday published a writeup on the two Exchange zero-day flaws, saying it first observed the attacks in early August being used to drop “webshells.” These web-based backdoors offer attackers an easy-to-use, password-protected hacking tool that can be accessed over the Internet from any browser.
“We detected webshells, mostly obfuscated, being dropped to Exchange servers,” GTSC wrote. “Using the user-agent, we detected that the attacker uses Antsword, an active Chinese-based opensource cross-platform website administration tool that supports webshell management. We suspect that these come from a Chinese attack group because the webshell codepage is 936, which is a Microsoft character encoding for simplified Chinese.”
GTSC’s advisory includes details about post-compromise activity and related malware, as well as steps it took to help customers respond to active compromises of their Exchange Server environment. But the company said it would withhold more technical details of the vulnerabilities for now.
In March 2021, hundreds of thousands of organizations worldwide had their email stolen and multiple backdoor webshells installed, all thanks to four zero-day vulnerabilities in Exchange Server.
Granted, the zero-day flaws that powered that debacle were far more critical than the two detailed this week, and there are no signs yet that exploit code has been publicly released (that will likely change soon). But part of what made last year’s Exchange Server mass hack so pervasive was that vulnerable organizations had little or no advance notice on what to look for before their Exchange Server environments were completely owned by multiple attackers.
Microsoft is quick to point out that these zero-day flaws require an attacker to have a valid username and password for an Exchange user, but this may not be such a tall order for the hackers behind these latest exploits against Exchange Server.
Steven Adair is president of Volexity, the Virginia-based cybersecurity firm that was among the first to sound the alarm about the Exchange zero-days targeted in the 2021 mass hack. Adair said GTSC’s writeup includes an Internet address used by the attackers that Volexity has tied with high confidence to a China-based hacking group that has recently been observed phishing Exchange users for their credentials.
In February 2022, Volexity warned that this same Chinese hacking group was behind the mass exploitation of a zero-day vulnerability in the Zimbra Collaboration Suite, which is a competitor to Microsoft Exchange that many enterprises use to manage email and other forms of messaging.
If your organization runs Exchange Server, please consider reviewing the Microsoft mitigations and the GTSC post-mortem on their investigations.

This month’s Patch Tuesday offers a little something for everyone, including security updates for a zero-day flaw in Microsoft Windows that is under active attack, and another Windows weakness experts say could be used to power a fast-spreading computer worm. Also, Apple has also quashed a pair of zero-day bugs affecting certain macOS and iOS users, and released iOS 16, which offers a new privacy and security feature called “Lockdown Mode.” And Adobe axed 63 vulnerabilities in a range of products.
Microsoft today released software patches to plug at least 64 security holes in Windows and related products. Worst in terms of outright scariness is CVE-2022-37969, which is a “privilege escalation” weakness in the Windows Common Log File System Driver that allows attackers to gain SYSTEM-level privileges on a vulnerable host. Microsoft says this flaw is already being exploited in the wild.
Kevin Breen, director of cyber threat research at Immersive Labs, said any vulnerability that is actively targeted by attackers in the wild must be put to the top of any patching list.
“Not to be fooled by its relatively low CVSS score of 7.8, privilege escalation vulnerabilities are often highly sought after by cyber attackers,” Breen said. “Once an attacker has managed to gain a foothold on a victim’s system, one of their first actions will be to gain a higher level of permissions, allowing the attacker to disable security applications and any device monitoring. There is no known workaround to date, so patching is the only effective mitigation.”
Satnam Narang at Tenable said CVE-2022-24521 — a similar vulnerability in the same Windows log file component — was patched earlier this year as part of Microsoft’s April Patch Tuesday release and was also exploited in the wild.
“CVE-2022-37969 was disclosed by several groups, though it’s unclear if CVE-2022-37969 is a patch-bypass for CVE-2022-24521 at this point,” Narang said.
Another vulnerability Microsoft patched this month — CVE-2022-35803 — also seems to be related to the same Windows log file component. While there are no indications CVE-2022-35803 is being actively exploited, Microsoft suggests that exploitation of this flaw is more likely than not.
Trend Micro’s Dustin Childs called attention to CVE-2022-34718, a remote code execution flaw in the Windows TCP/IP service that could allow an unauthenticated attacker to execute code with elevated privileges on affected systems without user interaction.
“That officially puts it into the ‘wormable’ category and earns it a CVSS rating of 9.8,” Childs said. “However, only systems with IPv6 enabled and IPSec configured are vulnerable. While good news for some, if you’re using IPv6 (as many are), you’re probably running IPSec as well. Definitely test and deploy this update quickly.”
Cisco Talos warns about four critical vulnerabilities fixed this month — CVE-2022-34721 and CVE-2022-34722 — which have severity scores of 9.8, though they are “less likely” to be exploited, according to Microsoft.
“These are remote code execution vulnerabilities in the Windows Internet Key Exchange protocol that could be triggered if an attacker sends a specially crafted IP packet,” wrote Jon Munshaw and Asheer Malhotra. “Two other critical vulnerabilities, CVE-2022-35805 and CVE-2022-34700 exist in on-premises instances of Microsoft Dynamics 365. An authenticated attacker could exploit these vulnerabilities to run a specially crafted trusted solution package and execute arbitrary SQL commands. The attacker could escalate their privileges further and execute commands as the database owner.”
Not to be outdone, Apple fixed at least two zero-day vulnerabilities when it released updates for iOS, iPadOS, macOS and Safari. CVE-2022-32984 is a problem in the deepest recesses of the operating system (the kernel). Apple pushed an emergency update for a related zero-day last month in CVE-2022-32983, which could be used to foist malware on iPhones, iPads and Macs that visited a booby-trapped website.
Also listed under active attack is CVE-2022-32817, which has been fixed on macOS 12.6 (Monterey), macOS 11.7 (Big Sur), iOS 15.7 and iPadOS 15.7, and iOS 16. The same vulnerability was fixed in Apple Watch in July 2022, and credits Xinru Chi of Japanese cybersecurity firm Pangu Lab.
“Interestingly, this CVE is also listed in the advisory for iOS 16, but it is not called out as being under active exploit for that flavor of the OS,” Trend Micro’s Childs noted. “Apple does state in its iOS 16 advisory that ‘Additional CVE entries to be added soon.’ It’s possible other bugs could also impact this version of the OS. Either way, it’s time to update your Apple devices.”
Apple’s iOS 16 includes two new security and privacy features — Lockdown Mode and Safety Check. Wired.com describes Safety Check as a feature for users who are at risk for, or currently experiencing, domestic abuse.
“The tool centralizes a number of controls in one place to make it easier for users to manage and revoke access to their location data and reset privacy-related permissions,” wrote Lily Hay Newman.
“Lockdown Mode, on the other hand, is meant for users who potentially face targeted spyware attacks and aggressive state-backed hacking. The feature comprehensively restricts any nonessential iOS features so there are as few potential points of entry to a device as possible. As more governments and repressive entities around the world have begun purchasing powerful commodity spyware to target individuals of particular importance or interest, iOS’s general security defenses haven’t been able to keep pace with these specialized threats.”
To turn on Lockdown Mode in iOS 16, go to Settings, then Privacy and Security, then Lockdown Mode. Safety Check is located in the same area.
Finally, Adobe released seven patches addressing 63 security holes in Adobe Experience Manager, Bridge, InDesign, Photoshop, InCopy, Animate, and Illustrator. More on those updates is here.
Don’t forget to back up your data and/or system before applying any security updates. If you experience glitches or problems installing any of these patches this month, please consider leaving a comment about it below; there’s a decent chance other readers have experienced the same and may chime in here with useful tips.
Microsoft today released updates to fix a record 141 security vulnerabilities in its Windows operating systems and related software. Once again, Microsoft is patching a zero-day vulnerability in the Microsoft Support Diagnostics Tool (MSDT), a service built into Windows. Redmond also addressed multiple flaws in Exchange Server — including one that was disclosed publicly prior to today — and it is urging organizations that use Exchange for email to update as soon as possible and to enable additional protections.
In June, Microsoft patched a vulnerability in MSDT dubbed “Follina” that had been used in active attacks for at least three months prior. This latest MSDT bug — CVE-2022-34713 — is a remote code execution flaw that requires convincing a target to open a booby-trapped file, such as an Office document. Microsoft this month also issued a different patch for another MSDT flaw, tagged as CVE-2022-35743.
The publicly disclosed Exchange flaw is CVE-2022-30134, which is an information disclosure weakness. Microsoft also released fixes for three other Exchange flaws that rated a “critical” label, meaning they could be exploited remotely to compromise the system and with no help from users. Microsoft says addressing some of the Exchange vulnerabilities fixed this month requires administrators to enable Windows Extended protection on Exchange Servers. See Microsoft’s blog post on the Exchange Server updates for more details.
“If your organization runs local exchange servers, this trio of CVEs warrant an urgent patch,” said Kevin Breen, director of cyber threat research for Immerse Labs. “Exchanges can be treasure troves of information, making them valuable targets for attackers. With CVE-2022-24477, for example, an attacker can gain initial access to a user’s host and could take over the mailboxes for all exchange users, sending and reading emails and documents. For attackers focused on Business Email Compromise this kind of vulnerability can be extremely damaging.”
The other two critical Exchange bugs are tracked as CVE-2022-24516 and CVE-2022-21980. It’s difficult to believe it’s only been a little more than a year since malicious hackers worldwide pounced in a bevy of zero-day Exchange vulnerabilities to remotely compromise the email systems for hundreds of thousands of organizations running Exchange Server locally for email. That lingering catastrophe is reminder enough that critical Exchange bugs deserve immediate attention.
The SANS Internet Storm Center‘s rundown on Patch Tuesday warns that a critical remote code execution bug in the Windows Point-to-Point Protocol (CVE-2022-30133) could become “wormable” — a threat capable of spreading across a network without any user interaction.
“Another critical vulnerability worth mentioning is an elevation of privilege affecting Active Directory Domain Services (CVE-2022-34691),” SANS wrote. “According to the advisory, ‘An authenticated user could manipulate attributes on computer accounts they own or manage, and acquire a certificate from Active Directory Certificate Services that would allow elevation of privilege to System.’ A system is vulnerable only if Active Directory Certificate Services is running on the domain. The CVSS for this vulnerability is 8.8.”
Breen highlighted a set of four vulnerabilities in Visual Studio that earned Microsoft’s less-dire “important” rating but that nevertheless could be vitally important for the security of developer systems.
“Developers are empowered with access to API keys and deployment pipelines that, if compromised, could be significantly damaging to organizations,” he said. “So it’s no surprise they are often targeted by more advanced attackers. Patches for their tools should not be overlooked. We’re seeing a continued trend of supply-chain compromise too, making it vital that we ensure developers, and their tools, are kept up-to-date with the same rigor we apply to standard updates.”
Greg Wiseman, product manager at Rapid7, pointed to an interesting bug Microsoft patched in Windows Hello, the biometric authentication mechanism for Windows 10. Microsoft notes that the successful exploitation of the weakness requires physical access to the target device, but would allow an attacker to bypass a facial recognition check.
Wiseman said despite the record number of vulnerability fixes from Redmond this month, the numbers are slightly less dire.
“20 CVEs affect their Chromium-based Edge browser and 34 affect Azure Site Recovery (up from 32 CVEs affecting that product last month),” Wiseman wrote. “As usual, OS-level updates will address a lot of these, but note that some extra configuration is required to fully protect Exchange Server this month.”
As it often does on Patch Tuesday, Adobe has also released security updates for many of its products, including Acrobat and Reader, Adobe Commerce and Magento Open Source. More details here.
