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.

Video editing software CapCut users are being targeted by attackers to push different strains of malware. For those that are not aware of that CapCut is, it is a video editor and maker for TikTok and is the official one at that (ByteDance also owns TikTok). With over 500 million downloads from Google Play alone it is clearly a very popular app for people to grab to feed their TikTok streams with. It was only a matter of time before someone decided to go after the poplar app and with the growing number of bans and lock outs for ByteDance and their services, offering what appears to be an alternative way to get this software makes sense (from an attacker perspective).

PyPI (the Python Package Index) has stopped allowing the creation of new accounts and the upload of new packages. This move has been put in place to deal with a massive increase in identified malicious users and packages. This decision comes as other repositories like NPM and even Microsoft VSCode have identified new malware posing as well-known projects. Supply chain attacks and typo-squatting are not really a new thing and increases in attacks on repositories often happen on a fairly regular basis. However, the increase across three popular repos can been seen as a larger threat when put in context of the general IT market.

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.

It was only a matter of time before something like this happened. As services like ChatGPT, Midjourney, Bard and other “AI” platform we viral, threat actors were bound to start trying to get in on the action. ChatGPT and Midjourney were easy targets for this as neither has a standalone app yet. To use them you have to get to their online presence; ChatGPT’s website or Midjourney’s Discord. This gap allowed the threat group known as BatLoader to start impersonating both of them via cleverly crafted Google search ads.

They have also noted that this new beacon (called Geacon) has been popping up on malware review sites like Virus Total in the past few months. The new detections could be part of red-teaming exercises, but the increase seems to indicate that real-world malicious activity is also part of the surge in detections.
