A couple of days ago an email was sent to me about a new tool kit being sold on the darker side of the internet. The claim what that this new tool could kill the processes behind “any” AV, EDR, or XDR running on Windows 7 and newer. The same email included a link to what was supposed to be proof of its efficacy. I opened the link in a sandbox on a controlled VM just to be sure the link was not malicious all on its own. What I saw was nothing all that new, although it was a bit worrying.

On May 19th 2023 Barracuda disclosed that there was a critical vulnerability in their Email Security Gateway appliances. This vulnerability is tracked under CVE-2023-2868 and is listed as a remote command injection vulnerability. The flaw is present in software versions 5.1.3.001 up to 9.2.0.006 for the ESG appliances only. As this was disclosed as a Zero-Day vulnerability there was an accelerated patch release schedules with the first patches made available on May 20th.

This one will get filed in the “you knew it was going to happen” file. After the announcement of a few new top-level domains (TLDs) including .zip and .mov by Google the security world silently shook its head. The concept of using file extensions as TLDs is one that defies logic. As soon as I read about these new domains, I knew someone was going to create phishing or malware attacks with URLs that look like common file names. These attacks can leverage modern web design to make a target think they are using an application to run or open the file when they are really executing commands in the background to compromise their systems. Lo and behold! We now have file archiver in the browser as shown off by mr.d0x.

Wait, another danger of AI article? Yes, another one. Since far too many people and companies are ok with ignoring the dangers simply for the sake of the next big shiny thing, we thought we would at least be part of the awareness of it. I might also say “I told you so” when things do start to go sideways… ok I would not be that much of a jackass, but I do think that making sure to point out issues with new technology while others seem ok with glossing them over is a good idea.

The leak of tools used by threat groups, and spying agencies are events of inestimable importance in both the threat group and security worlds. To threat groups this is like free money. They now have access to someone else’s development efforts meaning they can spend less money developing the next payload for their own interests. On the security side it means that there is a high potential to see new variants of these tools hitting the wild which they now must defend against. It also increases the attack pool which they must defend against since now even unsophisticated groups have access to all the fun tools.

The Google Play Store is and has always been something of a playground for mobile malware groups. Over the past few years hundreds of malicious apps have been uncovered with tens of thousands of downloads. Everything from banking malware to information stealers and worse has been identified in the store. Google, to their credit, has tried to find a solution to this. The problem is that the mobile device theater is about as secure as the PC industry was in the late 90s given the shovel ware from mobile device makers, and then carriers.

In the never-ending saga of Ransomware, the threat groups that deploy or leverage this tool for financial gain are always looking for a new method of installation and ways to avoid increasingly sophisticated security measures. Although most organizations might not be employing overly sophisticated security, the really good targets might be. Even the use of advanced MDR/XDR makes the exposure window smaller when it comes to many ransomware attacks.

Popular open-source repository NPM is back in the news as a pair of packages were found to have malware in them. The malware in question is TurkoRat. TurkoRat is an open-source information stealer that has a few features attached to it. Among some of the components are things like a wallet grabber (wallets.js) which seems geared towards stealing crypto currency. Other components are ones you would expect from an InforStealer like credential theft etc. The package was found by ReversingLabs after it had been in place for two months.

As part of our ongoing (really never ending) series on modern ransomware, we are taking a look at a recent study of one Ransomware as a Service operation. In this case the look is at the Qilin scheme which was brought to light by Group-IB. They were able to infiltrate the group through a conversation with a recruiter (nothing like being invited in). The cybersecurity firm started their inside look in March of 2023 and what they found was eye opening. It shows that RaaS clearly pays well and that services like this make things easy and profitable for people looking to get in on the “fun” but might not have the skill set or infrastructure to do it on their own.

The same Ransomware gang that hit MSI recently also appears to have hit Pharmacy services provider PharMerica and stole information on 5.8 million patents. The data that was exfiltrated as part of the attack includes social security numbers, full name and address, health insurance, medications, and date of birth. PharMerica disclosed the breach to the Maine Attorney General on March 12th, 2023.
