The past few months have seen radical changes to our work and home life under the Coronavirus threat, upending norms and confining millions of American families within just four walls. In this context, it’s not surprising that more of us are spending an increasing portion of our lives online. But this brings with it some familiar cyber-risks. In Part 1 of this mini-series, we explained how cyber-criminals are looking to capitalize on these sweeping changes to society to further their own ends.
Now let’s take a look at what you can do to protect your family, your data, and access to your corporate accounts.
The bad guys are laser-focused on stealing your personal data and log-ins and increasingly see the remote worker as an easy target for leapfrogging into corporate networks. That’s not to mention the potential internet safety risks inherent in bored kids spending more time in front of their screens. To respond, you’ll need to create an equally focused “home security plan” governed by sensible policies and best practices. Here are some of the key areas to consider.
Protect your smart home and router
Increasingly, unprotected smart home devices are being targeted by cyber-criminals to turn into botnets to attack others. They might also provide sophisticated attackers with a stepping-stone into your corporate systems, via the home network. The home router, with its known flaws, is (after the modem) the digital front door to the smart home and the basis for your networking, so it should be first in any security strategy. Consider the following when tackling home network security:
|

Secure your home office
Cyber-criminals are primed to take advantage of distracted home workers and potentially less secure PCs/devices. Secure this environment by doing the following:
|
|
Stay safe from phishing
Phishing is the number one tactic used by attackers to trick you into installing malware or handing over your log-ins. Emails, text messages, social media messages and more are spoofed to appear as if sent by a legitimate company or contact. In response:
|
|
Use video conferencing safely
New videoconferencing platforms can introduce risk, especially if you’re not familiar with the default settings. Here’s how to stay safe when video conferencing:
|
|
Stay safe shopping and banking
Next, protect your financial information and stay safe from e-commerce fraud by doing the following:
|
|
Think about online safety for kids
They may be under your roof for more hours of the day than usual, but your children are also likely to be spending more time online. That means you need to have a measured conversation with them about internet safety, backed up with parental controls. Consider the following:
|
|
Mobile security best practices
Finally, sheltering at home has limits, particularly for restless kids. When they go to the store or out to the park, facemasks notwithstanding, they’re likely going to use their mobile devices, just as they’ll continue to do at home. Of course, you’re not exempt either from mobile threats. Ensure mobile security by

When it comes to protecting the home from security and privacy threats during lockdown, leave no stone unturned. Cyber-criminals will always look for the weak link in the chain and focus their efforts there. Network security is important, but it doesn’t replace the need for protection on each individual device. You’ll need to cover your router, network, smart devices, and all endpoints (PCs, laptops, mobiles and other devices). Here’s how Trend Micro can help:

Maintaining your family’s security and privacy on all their devices during the coronavirus lockdown above all means changing your mindset, to take into account the mix of work and play in the household during the “new normal.” Use these tips and tools during lockdown and you’ll be well on your way to ensuring you and your family’s safety from malicious viruses—both digital and natural.
The post Top Tips For Home Cybersecurity And Privacy In A Coronavirus-Impacted World (Part 2) appeared first on .
Welcome to the new normal. We’re all now living in a post-COVID-19 world characterized by uncertainty, mass home working and remote learning. The lines demarcating normal life have shifted abruptly – perhaps never to return. That’s not the worst that can happen, as we all know, but it does mean we all need to get used to new ways of living, working and studying from home. This has major implications for the online safety, security and privacy of our families.
To help you adapt to these new conditions while protecting what matters most, Trend Micro has developed a two-part blog series on “The New Normal.” Part 1 identifies the scope and specific cyber-threats of the new normal. Part 2 provides security tips and products to help address those threats.
In April, nearly 300 million Americans were estimated to be in government-mandated lockdown. Even as some businesses, municipalities and states begin to relax these rules, experts have warned of subsequent waves of the virus, which could result in new localized lockdowns. In short, a lot of people will continue to work from home, while their children, also at home, attempt to study remotely from their mobile devices.
This has considerable implications for how we spend our time. Without that morning commute to work or school, more of it than ever will involve sitting in front of a desktop, laptop, tablet or smartphone screen. Even the smart TV is enlisted. Dangers include

|
Unfortunately, the increase in working from home (WFH), especially for those not used to it, may lead to an increase in risky behavior, such as: using non-approved apps for work; visiting non work-related sites on work devices; and using personal devices to access work resources. Recent global Trend Micro research found that:

This is not about restricting your freedom to visit the sites you want to visit while at home. It’s about reducing the risk of exposing corporate data and systems to possible malware.
Unsurprisingly, there has also been a major uptick in the volume of cyber-threats targeting home users. With a captive audience to aim at, it’s a huge opportunity for cyber-criminals to steal your log-ins and personal data to sell to fraudsters, or even to steal corporate passwords and information for a potentially bigger pay-off. They are helped by the fact that many home workers may be more distracted than they usually would be at the office, especially if they have young children. Your kids may even share the same laptops or PCs as you, potentially visiting risky sites and/or downloading unapproved apps.
There’s also a chance that, unless you have a corporate machine at home, your personal computing equipment is less secure than the kit you had in the office. Add to that the fact that support from the IT department may be less forthcoming than usual, given that stretched teams are overwhelmed with requests, while themselves struggling to WFH. One recent report claimed that nearly half (47%) of IT security pros have been taken off some or all of their typical security tasks to support other IT-related jobs. In another, only 59% of respondents said they believe their cybersecurity team has the right tools and resources at home to perform their job effectively.
It’s time to step up and take security into your own hands. Stay on the lookout for the following threats.

World Password Day isn’t the most popular day on the calendar, but it’s an important reminder that good password hygiene is essential to staying safe online. This World Password Day, we’d like to talk about improving your password hygiene, how you can help your friends and family improve theirs, and what the future of authentication holds.
The SolarWinds hack in 2020 is one of the most devastating hacks in the history of the internet. Close to 20,000 company’s systems were compromised, losing billions of pieces of data in the process. If you’re one of the 37% of Americans that go long periods of time without updating passwords*, large-scale attacks like SolarWinds can be devastating. By stealing so many login credentials simultaneously, attackers can potentially access exponentially more accounts by reusing leaked credentials on different sites. Unfortunately this is not an isolated event, data breaches from websites and services we frequently use continue to happen through 2021 as well.
According to a recent survey we conducted, 34% of Americans have reused the same, or similar, password more than once. By using the same password for multiple accounts, attackers only need to find one password, creating a domino effect that makes it easier to access more accounts. If that password is weak, it becomes even easier to tip over that first domino.
Our guidance is to create strong, hard-to-guess passwords to protect your accounts. We recommend creating a unique password for every online account, using more than 16 characters, with upper and lower case letters, some numbers, and special symbols, to make a stronger than average password. How are you supposed to remember all of those strong passwords, though?
Well, password managers, especially those included in comprehensive security suites like McAfee® Total Protection, do much of the heavy lifting for you. For instance, McAfee’s integrated password manager not only helps you create stronger passwords and store them, but will also autofill your credentials and log you into websites as well. These convenient features extend beyond just your computer and can be used on other devices like your phone and tablet. Best of all, password managers that are an integrated part of a security suite can be monitored, so you’ll be alerted if your passwords get exposed in a data breach.
You’ve already taken a step towards improving your password hygiene by reading this blog post. But the next step is, have an honest look at your passwords. Do you write them down, use the same for many accounts, or use weak ones? Then it may be time for a change to better protect your accounts and the personal info in those accounts.
If you’re like a certain member of my family—that will remain nameless, Mom—who kept their passwords written down in a notepad, making the change to a password manager (McAfee’s, naturally) was a life-changing moment. Not only did it help her see just how often she was using the same login credentials, she now has an easy way to store, auto-fill, and even generate strong passwords across all her accounts and devices. An intended bonus was that she also realized how many accounts she was no longer using!
Now that you know more about what makes a strong password and how to protect them, let’s talk about why strong passwords are just the start of keeping your accounts safe. You’re probably already using Two-Factor Authentication for apps and services, but you may not have heard the term before. Two-Factor Authentication, or 2FA, is the second layer of protection to authenticate or prove you are the owner of this account. If you’ve received a text message or an email to confirm a new account signup, that’s a type of 2FA.
Text messages and email aren’t the only types of 2FA. There are USB keys, apps, and even systems built-in to your phone, like facial recognition to open phone apps, for example. Some popular 2FA options are USB keys and Google Authenticator.
The great thing about 2FA is that it helps make your strong passwords even more effective by stopping an attacker from using stolen credentials. If you fell victim to a phishing attack that looked like your bank’s website, the attacker would have your email and password combination. Without 2FA, they could log into your account and pretend they’re you. With 2FA in place, it becomes much harder for an attacker to access your account because they’re missing that last important piece of information.
Humans are almost always the weakest link when it comes to securing information. But by committing ourselves to better password practices, with help from the latest technology, we can make sure passwords are a strong link in our security chain; one that will only get stronger in the future.
For instance, using a device like a key-fob, new passwordless systems can authenticate a user without entering their login details. Not only does this make logging into your accounts lightning fast, you also never have to remember a complicated password again.
Biometric locks, like FaceID, are another example of passwordless entry. Using your face, or a fingerprint to authenticate yourself makes it much harder for attackers to break into your accounts.
We hope this Password Day post has helped answer some questions about password hygiene and how to take better care of your online accounts. Online security changes from day to day, so staying aware of new technologies and building safe new habits is essential. Perhaps one day this day will no longer need to exist on our calendars, as we look to a future where we might not need passwords at all. While we collectively make strikes towards this future, let’s celebrate this day while it lasts.

The post World Password Day: Make Passwords the Strongest Link in Your Online Security appeared first on McAfee Blogs.
Passwords: we entrust our most important data to these strings of letters, numbers, and special characters. So, we should make sure our passwords are words or phrases that we can easily remember, right? While this might be the most convenient option, there are more secure ways to digitally lock up your most sensitive personally identifiable information (PII). In celebration of World Password Day, we’re diving into how you can practice top-notch password security without compromising convenience.1
Over the years, the password has remained a good first line of defense against cyberattacks. However, most of us tend to choose passwords based on memorable things from our lives, like family names or our pets’ birthdays. As it turns out, these details are easy for hackers to find on social media sites like Facebook or LinkedIn. It’s also human nature to opt for convenience, and for many people that means setting easy-to-remember and easy-to-guess passwords. Plus, out of convenience, people often reuse passwords across multiple accounts and services. The downside is that if one account becomes compromised, all accounts become compromised.
As an alternative to single-word passwords, many security experts advocate for passphrases over passwords. Passphrases are longer strings of words and characters that are easier for you to remember and harder for nefarious software and cybercriminals to guess than random strings of upper and lowercase letters, numbers and symbols. But, according to a study, the average American internet user was projected to have 300 online accounts by 2022.2 Can you imagine memorizing 300 different passphrases? We can all agree that sounds pretty unrealistic, so users tend to look for other solutions.
If the answer is yes, you may want to reconsider, as there are several risks associated with this practice. Although it’s convenient to have your browser save your passwords, they tend to do a lousy job of safeguarding your passwords, credit card numbers and personal details, such as your name and address.
Let’s take Google Chrome, for example. Unlike most dedicated password managers, Chrome doesn’t use a primary password to encrypt all your credentials. (Note that some browsers do use one, and are therefore more secure, though you’ll still need to trust your browser provider.) This makes your Chrome-stored passwords relatively weak to “local” attacks. For example, if someone gets hold of—or guesses—your Windows password, they can then see all the logins stored in your browser’s password manager.
Another consideration to note is that the security of all your accounts is tied to your browser account’s security. Let’s say you use the sync option to make your credentials available on all your devices. This means that logins are stored in the cloud and, though encrypted, if someone manages to hack into your browser account, they will gain access to all your logins.
What can you do to help ensure your online profiles are kept safe without spending hours managing a complex list of passwords? Here are some easy ways to lock down your digital life without sacrificing convenience:
A password manager is a software application that stores your passwords and other sensitive information. You can install it on computers or mobile devices and store all passwords in an encrypted file (or database). The best option is to use a password manager like McAfee True Key to store and create strong, random passwords for each site you visit. You’ll have one primary password that grants access to the rest of them—ideally, a long and random passphrase that you can remember. Once everything is set up, it should be seamless. As you log in to new sites, the password manager will offer to save your credentials for later use.
One of the best ways to protect your accounts against unauthorized access is to turn on two-factor authentication for every site that offers it. Using two-factor authentication means a site will prompt you for a unique security code, in addition to your password, whenever you log in to an account for which you have enabled this feature.
Two-factor authentication adds an extra layer of security by requiring another form of identification after you enter your username and password. Some services send a temporary passcode over text message. Others require the user to approve login attempts from new devices using an app. If someone steals your device or gains access to your account details, they’re out of luck unless they also have access to this second piece of information. Two-factor authentication is available on a wide range of websites and can help keep your accounts safe from would-be hackers, so you should always use it when available.
A VPN, or virtual private network, encrypts your data and masks your online behavior from snooping third parties. When you go to a website, your computer connects to the server where the site is hosted, and that website can see a certain amount of data about you and your computer. With a VPN, you connect to a private server first, which scrambles your data and makes it more difficult for digital eavesdroppers to track what you’re doing online.
VPNs can provide users with greater peace of mind when on the go. Say you’re traveling on a business trip and need to connect to the Wi-Fi network provided by your hotel. Shifty characters often lurk on unprotected, free networks (such as those provided by hotels, coffee shops, airports, etc.) to lift PII from people handling sensitive emails, making banking transactions, or shopping online. McAfee Safe Connect VPN encrypts your online activity with bank-grade encryption to protect your data from prying eyes. With a premium paid plan, you can protect up to five devices at once and enjoy unlimited data protection.
With your growing number of accounts all requiring passwords—emails, social media profiles, online banking—it’s no wonder that people tend to reuse passwords across multiple sites. This may be convenient, but it creates significant security risks if a suspicious actor manages to obtain one of your passwords and attempts to use it elsewhere. That’s why having strong passwords matters.
Do yourself a favor and opt for a dedicated password manager that will auto-save and store your credentials for you, so you only have one password to remember. Who says security and simplicity can’t coexist?
The post This World Password Day, Here’s How a Password Manager Can Simplify Your Life appeared first on McAfee Blog.
Whether using the internet for play or work, you want to spend your time online enjoying the peace of mind that comes with having a secure network.
You don’t want to contend with someone taking your personal data — whether it’s credit card information, passwords, or bank account details — via malware or a data breach on your Android, Windows, or Apple iOS device.
Fortunately, with some sensible precautions and simple steps, you can use your connected devices productively without worrying about cybercriminals and malicious software. This article explains how to stop hackers from getting access to your sensitive data.
You can take steps to protect your different computing and mobile devices and operating systems. These steps can be divided into technological solutions and the right awareness and information to provide a comforting measure of self-protection.
It’s like learning karate for self-defense, giving you confidence as you negotiate the wider world (and hoping that you never have to use it).
When it comes to identity protection software, McAfee provides a proven solution with our identity protection and privacy services. The protection includes alerts if your sensitive information is found on the dark web (up to 10 months sooner than other providers), personal data cleanup from sites gathering and selling your information, and an unlimited virtual public network (VPN) service that protects your privacy as you use public Wi-Fi networks.
You’ll also get up to $1 million in identity theft coverage and hands-on restoration support to help you reclaim your identity.
Simple, obvious passwords and passcodes (like your street address, your birthday, your kids’ or pets’ names, or “1234” or “abcd”) are easy for cybercriminals to crack, giving them unwanted access to your private data.
The stronger your password, the better your protection. Some best password practices include:
It’s important not to be a standing target. Just as you should use different passwords for everything, you should regularly change your passwords. You should do this a few times a year (although some cyber experts say this might not be necessary if you have a long and very complicated password).
If you have a number of passwords that you update often, it might be worth getting a password manager like McAfee True Key to keep track of them. Not only will you not be faced with remembering all your different passwords or writing them down (also a no-no), but it can also help you create and store unique passwords.
The software uses the strongest encryption algorithms available to protect your passwords, scrambling them so no one else can access them. It’ll also suggest new passwords and automatically log you into your online accounts with just one master password.
Another important line of defense is multi-factor authentication (sometimes known as two-factor authentication). This system uses a password and a second piece of verification — often an SMS message sent to your Android device or iPhone — to authenticate your identity.
This provides hard-to-beat protection even if a hacker has your password. Besides receiving SMS codes, there are also code-generating apps and physical security keys.
Thinking before you click on an email or text is a very important defense against phishing scams. Your bank won’t send you an email or text notifying you that there’s been suspicious activity on your account.
Does getting a large refund from your phone company sound too good to be true? It is. Similarly, the Internal Revenue Service (IRS) won’t text to tell you that you owe them money, and princes aren’t going to give you a fortune out of the blue.
Internet users beware: If you’re not absolutely certain that the text message you received is from a legitimate and trusted source, delete it. You can always contact the business or person directly to confirm that the message is legit.
Any operating system or app you use is open to malicious cyberattacks. This is why you should keep all your software up to date with the latest versions. Software developers are continually fixing holes in their products and offering cybersecurity patches to make them as safe and hacker-proof as possible.
Make sure your software, firmware, and security settings are up to date on your home’s Wi-Fi router, as well. You can often change your settings to allow for automatic updates.
Sure, who doesn’t like to go to a cafe, library, or hotel lobby to use the free Wi-Fi? But security is often weak in these public networks. If you open your online banking account or access personal information, you may unwittingly be giving a personal invitation to eavesdropping cybercriminals.
This is where the bank-grade level of protection of McAfee Secure VPN comes in, which automatically turns on when you need it and keeps you safe on public Wi-Fi networks.
Even if your device does get hacked, you can protect vital information on your Windows or macOS system with an encryption program like BitLocker or FileVault. You can protect any hard drive you use, including portable ones and USB keys.
It’s also a good idea to only shop at encrypted websites marked with the prefix “HTTPS” in their URLs.
One of the best ways to surf the web in comfort while keeping hackers at bay is with the comprehensive solutions provided by McAfee Total Protection.
Your protection includes proactive measures (meaning we’ll guide you to the best choices for prevention), early detection, and expert identity theft support.
This means you’ll get identity monitoring, up to $1 million in identity theft coverage, lost wallet protection, premium antivirus software, a secure VPN, and personal data removal. In particular, our Personal Data Cleanup service will help find and remove your personal information from data broker websites and people search sites.
With McAfee, you don’t have to be afraid of hackers. Let us deal with them.
The post How to Stay One Step Ahead of Hackers appeared first on McAfee Blog.
Password protection is one of the most common security protocols available. By creating a unique password, you are both proving your identity and keeping your personal information safer. However, when every account you have requires a separate password, it can be an overwhelming task. While you should be concerned about the safety of your data, you also want to avoid the frustration of forgetting your password and being blocked from the information you need. However, the benefits of using strong, unique passwords outweigh the occasional inconvenience.
The main benefit of a strong password is security. Hackers work quickly when they are trying to access accounts. They want to steal as much information as they can in as short a time as possible. This makes an account with a strong password less inviting because cracking the code is much more involved.
A strong password also limits the damage that hackers can do to your personal accounts. A common strategy involves cracking the passwords of less secure sites with limited personal information. The hackers hope that they can use the password from your gym membership app to access information in your online banking account. Strong password protection prevents this situation.
When someone is registering an online account, it can be tempting to blaze through the password process. In order to move quickly, there are several poor password practices that people employ.
A password is considered strong when it is difficult for a hacker to crack it quickly. Sophisticated algorithms can run through many password combinations in a short time. A password that is long, complex and unique will discourage attempts to break into your accounts.
If you want a password that is memorable but strong, you can easily turn a phrase into a layered, complex password. In this process, it is important to note that you should not use personal information that is available online as part of your phrase.
Now, you have a password that you can remember while challenging the algorithms hackers use.
When you consider the number of accounts you need to protect, coming up with a properly layered password is a time-consuming task. Even if you are able to decide on a memorable phrase, there are just too many accounts that need passwords. A password manager is a helpful tool to keep you safe while you are online. It acts as a database for all of your passwords. Each time you create a new code, it stores it so that you can automatically enter it later. You only need to remember a single password to access the tools of your manager.
Most managers can also do the work of creating complex, layered passwords for your accounts. These will be a string of random numbers, letters and characters. They will not be memorable, but you are relying on the manager to do the memorizing. These machine-generated passwords are especially helpful for accounts you rarely access or that do not hold significant information.
For critical accounts like your bank account or a work-related account, it can be helpful to keep an offline list of your passwords. Complex passwords are meant to be difficult to remember. You may recall the phrase but not all the detailed changes that make it layered. Keeping a document on a zip drive or even in a physical paper file or journal will allow you to access your information if your hardware fails or you are switching to a new system.
Cracking passwords is just one of the strategies hackers use to steal information. In addition to using strong passwords, it is important to employ comprehensive security software. Strong passwords will help protect your online accounts. Strong overall security will keep your hardware and network safe from danger.

Apple and Microsoft recently released software updates to fix dozens of security holes in their operating systems. Microsoft today patched at least 60 vulnerabilities in its Windows OS. Meanwhile, Apple’s new macOS Sonoma addresses at least 68 security weaknesses, and its latest update for iOS fixes two zero-day flaws.
Last week, Apple pushed out an urgent software update to its flagship iOS platform, warning that there were at least two zero-day exploits for vulnerabilities being used in the wild (CVE-2024-23225 and CVE-2024-23296). The security updates are available in iOS 17.4, iPadOS 17.4, and iOS 16.7.6.
Apple’s macOS Sonoma 14.4 Security Update addresses dozens of security issues. Jason Kitka, chief information security officer at Automox, said the vulnerabilities patched in this update often stem from memory safety issues, a concern that has led to a broader industry conversation about the adoption of memory-safe programming languages [full disclosure: Automox is an advertiser on this site].
On Feb. 26, 2024, the Biden administration issued a report that calls for greater adoption of memory-safe programming languages. On Mar. 4, 2024, Google published Secure by Design, which lays out the company’s perspective on memory safety risks.
Mercifully, there do not appear to be any zero-day threats hounding Windows users this month (at least not yet). Satnam Narang, senior staff research engineer at Tenable, notes that of the 60 CVEs in this month’s Patch Tuesday release, only six are considered “more likely to be exploited” according to Microsoft.
Those more likely to be exploited bugs are mostly “elevation of privilege vulnerabilities” including CVE-2024-26182 (Windows Kernel), CVE-2024-26170 (Windows Composite Image File System (CimFS), CVE-2024-21437 (Windows Graphics Component), and CVE-2024-21433 (Windows Print Spooler).
Narang highlighted CVE-2024-21390 as a particularly interesting vulnerability in this month’s Patch Tuesday release, which is an elevation of privilege flaw in Microsoft Authenticator, the software giant’s app for multi-factor authentication. Narang said a prerequisite for an attacker to exploit this flaw is to already have a presence on the device either through malware or a malicious application.
“If a victim has closed and re-opened the Microsoft Authenticator app, an attacker could obtain multi-factor authentication codes and modify or delete accounts from the app,” Narang said. “Having access to a target device is bad enough as they can monitor keystrokes, steal data and redirect users to phishing websites, but if the goal is to remain stealth, they could maintain this access and steal multi-factor authentication codes in order to login to sensitive accounts, steal data or hijack the accounts altogether by changing passwords and replacing the multi-factor authentication device, effectively locking the user out of their accounts.”
CVE-2024-21334 earned a CVSS (danger) score of 9.8 (10 is the worst), and it concerns a weakness in Open Management Infrastructure (OMI), a Linux-based cloud infrastructure in Microsoft Azure. Microsoft says attackers could connect to OMI instances over the Internet without authentication, and then send specially crafted data packets to gain remote code execution on the host device.
CVE-2024-21435 is a CVSS 8.8 vulnerability in Windows OLE, which acts as a kind of backbone for a great deal of communication between applications that people use every day on Windows, said Ben McCarthy, lead cybersecurity engineer at Immersive Labs.
“With this vulnerability, there is an exploit that allows remote code execution, the attacker needs to trick a user into opening a document, this document will exploit the OLE engine to download a malicious DLL to gain code execution on the system,” Breen explained. “The attack complexity has been described as low meaning there is less of a barrier to entry for attackers.”
A full list of the vulnerabilities addressed by Microsoft this month is available at the SANS Internet Storm Center, which breaks down the updates by severity and urgency.
Finally, Adobe today issued security updates that fix dozens of security holes in a wide range of products, including Adobe Experience Manager, Adobe Premiere Pro, ColdFusion 2023 and 2021, Adobe Bridge, Lightroom, and Adobe Animate. Adobe said it is not aware of active exploitation against any of the flaws.
By the way, Adobe recently enrolled all of its Acrobat users into a “new generative AI feature” that scans the contents of your PDFs so that its new “AI Assistant” can “understand your questions and provide responses based on the content of your PDF file.” Adobe provides instructions on how to disable the AI features and opt out here.
If only Patch Tuesdays came around infrequently — like total solar eclipse rare — instead of just creeping up on us each month like The Man in the Moon. Although to be fair, it would be tough for Microsoft to eclipse the number of vulnerabilities fixed in this month’s patch batch — a record 147 flaws in Windows and related software.
Yes, you read that right. Microsoft today released updates to address 147 security holes in Windows, Office, Azure, .NET Framework, Visual Studio, SQL Server, DNS Server, Windows Defender, Bitlocker, and Windows Secure Boot.
“This is the largest release from Microsoft this year and the largest since at least 2017,” said Dustin Childs, from Trend Micro’s Zero Day Initiative (ZDI). “As far as I can tell, it’s the largest Patch Tuesday release from Microsoft of all time.”
Tempering the sheer volume of this month’s patches is the middling severity of many of the bugs. Only three of April’s vulnerabilities earned Microsoft’s most-dire “critical” rating, meaning they can be abused by malware or malcontents to take remote control over unpatched systems with no help from users.
Most of the flaws that Microsoft deems “more likely to be exploited” this month are marked as “important,” which usually involve bugs that require a bit more user interaction (social engineering) but which nevertheless can result in system security bypass, compromise, and the theft of critical assets.
Ben McCarthy, lead cyber security engineer at Immersive Labs called attention to CVE-2024-20670, an Outlook for Windows spoofing vulnerability described as being easy to exploit. It involves convincing a user to click on a malicious link in an email, which can then steal the user’s password hash and authenticate as the user in another Microsoft service.
Another interesting bug McCarthy pointed to is CVE-2024-29063, which involves hard-coded credentials in Azure’s search backend infrastructure that could be gleaned by taking advantage of Azure AI search.
“This along with many other AI attacks in recent news shows a potential new attack surface that we are just learning how to mitigate against,” McCarthy said. “Microsoft has updated their backend and notified any customers who have been affected by the credential leakage.”
CVE-2024-29988 is a weakness that allows attackers to bypass Windows SmartScreen, a technology Microsoft designed to provide additional protections for end users against phishing and malware attacks. Childs said one of ZDI’s researchers found this vulnerability being exploited in the wild, although Microsoft doesn’t currently list CVE-2024-29988 as being exploited.
“I would treat this as in the wild until Microsoft clarifies,” Childs said. “The bug itself acts much like CVE-2024-21412 – a [zero-day threat from February] that bypassed the Mark of the Web feature and allows malware to execute on a target system. Threat actors are sending exploits in a zipped file to evade EDR/NDR detection and then using this bug (and others) to bypass Mark of the Web.”
Update, 7:46 p.m. ET: A previous version of this story said there were no zero-day vulnerabilities fixed this month. BleepingComputer reports that Microsoft has since confirmed that there are actually two zero-days. One is the flaw Childs just mentioned (CVE-2024-21412), and the other is CVE-2024-26234, described as a “proxy driver spoofing” weakness.
Satnam Narang at Tenable notes that this month’s release includes fixes for two dozen flaws in Windows Secure Boot, the majority of which are considered “Exploitation Less Likely” according to Microsoft.
“However, the last time Microsoft patched a flaw in Windows Secure Boot in May 2023 had a notable impact as it was exploited in the wild and linked to the BlackLotus UEFI bootkit, which was sold on dark web forums for $5,000,” Narang said. “BlackLotus can bypass functionality called secure boot, which is designed to block malware from being able to load when booting up. While none of these Secure Boot vulnerabilities addressed this month were exploited in the wild, they serve as a reminder that flaws in Secure Boot persist, and we could see more malicious activity related to Secure Boot in the future.”

Adobe today released nine patches tackling at least two dozen vulnerabilities in a range of software products, including Adobe After Effects, Photoshop, Commerce, InDesign, Experience Manager, Media Encoder, Bridge, Illustrator, and Adobe Animate.
KrebsOnSecurity needs to correct the record on a point mentioned at the end of March’s “Fat Patch Tuesday” post, which looked at new AI capabilities built into Adobe Acrobat that are turned on by default. Adobe has since clarified that its apps won’t use AI to auto-scan your documents, as the original language in its FAQ suggested.
“In practice, no document scanning or analysis occurs unless a user actively engages with the AI features by agreeing to the terms, opening a document, and selecting the AI Assistant or generative summary buttons for that specific document,” Adobe said earlier this month.
