I don’t know how much of a thing this will end up being, but we are seeing ChatGPT-written malware in the wild.

…within a few weeks of ChatGPT going live, participants in cybercrime forums—­some with little or no coding experience­—were using it to write software and emails that could be used for espionage, ransomware, malicious spam, and other malicious tasks.

“It’s still too early to decide whether or not ChatGPT capabilities will become the new favorite tool for participants in the Dark Web,” company researchers wrote. “However, the cybercriminal community has already shown significant interest and are jumping into this latest trend to generate malicious code.”

Last month, one forum participant posted what they claimed was the first script they had written and credited the AI chatbot with providing a “nice [helping] hand to finish the script with a nice scope.”

The Python code combined various cryptographic functions, including code signing, encryption, and decryption. One part of the script generated a key using elliptic curve cryptography and the curve ed25519 for signing files. Another part used a hard-coded password to encrypt system files using the Blowfish and Twofish algorithms. A third used RSA keys and digital signatures, message signing, and the blake2 hash function to compare various files.

Check Point Research report.

ChatGPT-generated code isn’t that good, but it’s a start. And the technology will only get better. Where it matters here is that it gives less skilled hackers—script kiddies—new capabilities.

It’s remotely triggerable, but attackers would already have pretty deep network access if they could “prime” your server for compromise.

Are you an online oversharer? Do you give your full birthday to all your online shopping accounts? Have a few companies you have accounts with been breached but you didn’t take any action at the time? If you have bad digital habits, now is an excellent time to reset your digital presence. 

In isolation, these small digital transgressions don’t seem like a problem; however, cybercriminals can gather the bits and pieces of information you release into the world and Frankenstein them together to create believable impersonations or entirely new identities. 

To protect your identity, here are a few ways to limit the amount of personally identifiable information (PII) you share online, plus a few tools that can help you identify and close your current security holes. 

Bad Online Habits That Put Your PII at Risk 

Most digital bad habits seem insignificant; however, the more bad habits you have that pile-up, the more at risk your PII and your identity can be. Check out this list of three common habits that you should consider breaking today and why. 

1. Volunteering too much information.

When you sign up for new online shopping accounts, some companies ask for your birthday, your age, your middle name, and primary and secondary phone numbers and email addresses. While it might be nice to receive a special coupon on your birthday, you may want to reconsider volunteering unnecessary private details. To compromise you can sign up with a nickname and leave your birth year blank. That way, if a cybergang ever breaches the company, the criminals won’t get far with your personal details. To steal an identity and ruin someone’s credit, sometimes all it takes it a full name, birthday, and phone number. 

2. Oversharing on social media.

Do you post your every thought and movement on social media? While curating the perfect online profile can be fun, it can also be dangerous to your online safety. For instance, posting “get to know you” quizzes are a gold mine for social engineers and cyber criminals, as the results often reveal potential password inspiration, security question answers, and your likes and dislikes. From here, criminals can take educated guesses at your passwords or tailor a social engineering scheme that’s most likely to fool you. Consider setting your social media profiles to private and blocking followers you don’t know personally. Or, just keep parts of your life a mystery to the wider world. 

3. Reusing passwords.

We can all agree that increasingly strict password requirements are leading to longer and more complex passwords that are confusing to cyber criminals and to the rightful account holders, too! It’s tempting to reuse passwords to reduce the burden on your memory, but this puts your valuable PII in danger. Password and username combinations are often information that’s leaked in company breaches. In what’s called a brute force attack, a cybercriminal can plug that same pairing into hundreds of websites and wait for a hit. Since unique passwords for all your dozens of accounts is imperative, entrust their safekeeping to a password manager.  

Grade Your Online Safety With McAfee Protection Score 

If you’re feeling uneasy about your online habits and the effect they may have had on your online safety, McAfee Protection Score gives you the information you need to take charge and make changes. Protection Score not only tells you how safe (or unsafe) you are, but the tool also offers suggestions on how you can raise your score, and thus be safer online. The service monitors data breaches and indicates when your email was part of a leak. Protection Score also dives into the dark web so you don’t have to. If your government ID or financial information appears, your score will take a large hit. 

Protection Score not only tells you how safe (or unsafe) you are, but the tool also offers suggestions on how you can raise your score, and thus be safer online. The sooner you know your weak points, the quicker and more completely you can fortify your defenses and clean up after months (or years) of bad habits. Knowledge is power in the right against cyber criminals, so Protection Score is an excellent partner to help adopt smarter habits on the path to better online security. 

Get the Whole Package With McAfee+ Ultimate 

With McAfee+ Ultimate, you not only get a Protection Score but a host of other top-rate tools to protect your identity, retain your online privacy, and help you recover from an identity theft. Running an antivirus, connecting to a VPN and installing web protection on your browser are all ways to increase your Protection Score, and these features are available with McAfee’s most thorough privacy, identity, and device protection service.

Microsoft today released updates to fix nearly 100 security flaws in its Windows operating systems and other software. Highlights from the first Patch Tuesday of 2023 include a zero-day vulnerability in Windows, printer software flaws reported by the U.S. National Security Agency, and a critical Microsoft SharePoint Server bug that allows a remote, unauthenticated attacker to make an anonymous connection.

At least 11 of the patches released today are rated “Critical” by Microsoft, meaning they could be exploited by malware or malcontents to seize remote control over vulnerable Windows systems with little or no help from users.

Of particular concern for organizations running Microsoft SharePoint Server is CVE-2023-21743. This is a Critical security bypass flaw that could allow a remote, unauthenticated attacker to make an anonymous connection to a vulnerable SharePoint server. Microsoft says this flaw is “more likely to be exploited” at some point.

But patching this bug may not be as simple as deploying Microsoft updates. Dustin Childs, head of threat awareness at Trend Micro’s Zero Day Initiative, said sysadmins need to take additional measures to be fully protected from this vulnerability.

“To fully resolve this bug, you must also trigger a SharePoint upgrade action that’s also included in this update,” Childs said. “Full details on how to do this are in the bulletin. Situations like this are why people who scream ‘Just patch it!’ show they have never actually had to patch an enterprise in the real world.”

Eighty-seven of the vulnerabilities earned Redmond’s slightly less dire “Important” severity rating. That designation describes vulnerabilities “whose exploitation could result in compromise of the confidentiality, integrity, or availability of user data, or of the integrity or availability of processing resources.”

Among the more Important bugs this month is CVE-2023-21674, which is an “elevation of privilege” weakness in most supported versions of Windows that has already been abused in active attacks.

Satnam Narang, senior staff research engineer at Tenable, said although details about the flaw were not available at the time Microsoft published its advisory on Patch Tuesday, it appears this was likely chained together with a vulnerability in a Chromium-based browser such as Google Chrome or Microsoft Edge in order to break out of a browser’s sandbox and gain full system access.

“Vulnerabilities like CVE-2023-21674 are typically the work of advanced persistent threat (APT) groups as part of targeted attacks,” Narang said. “The likelihood of future widespread exploitation of an exploit chain like this is limited due to auto-update functionality used to patch browsers.”

By the way, when was the last time you completely closed out your Web browser and restarted it? Some browsers will automatically download and install new security updates, but the protection from those updates usually only happens after you restart the browser.

Speaking of APT groups, the U.S. National Security Agency is credited with reporting CVE-2023-21678, which is another “important” vulnerability in the Windows Print Spooler software.

There have been so many vulnerabilities patched in Microsoft’s printing software over the past year (including the dastardly PrintNightmare attacks and borked patches) that KrebsOnSecurity has joked about Patch Tuesday reports being sponsored by Print Spooler. Tenable’s Narang points out that this is the third Print Spooler flaw the NSA has reported in the last year.

Kevin Breen at Immersive Labs called special attention to CVE-2023-21563, which is a security feature bypass in BitLocker, the data and disk encryption technology built into enterprise versions of Windows.

“For organizations that have remote users, or users that travel, this vulnerability may be of interest,” Breen said. “We rely on BitLocker and full-disk encryption tools to keep our files and data safe in the event a laptop or device is stolen. While information is light, this appears to suggest that it could be possible for an attacker to bypass this protection and gain access to the underlying operating system and its contents. If security teams are not able to apply this patch, one potential mitigation could be to ensure Remote Device Management is deployed with the ability to remotely disable and wipe assets.”

There are also two Microsoft Exchange vulnerabilities patched this month — CVE-2023-21762 and CVE-2023-21745. Given the rapidity with which threat actors exploit new Exchange bugs to steal corporate email and infiltrate vulnerable systems, organizations using Exchange should patch immediately. Microsoft’s advisory says these Exchange flaws are indeed “more likely to be exploited.”

Adobe released four patches addressing 29 flaws in Adobe Acrobat and Reader, InDesign, InCopy, and Adobe Dimension. The update for Reader fixes 15 bugs with eight of these being ranked Critical in severity (allowing arbitrary code execution if an affected system opened a specially crafted file).

For a more granular rundown on the updates released today, see the SANS Internet Storm Center roundup. Nearly 100 updates is a lot, and there are bound to be a few patches that cause problems for organizations and end users. When that happens, AskWoody.com usually has the lowdown.

Please consider backing up your data and/or imaging your system before applying any updates. And please sound off in the comments if you experience any problems as a result of these patches.
