A recent malvertising and cryptocurrency-related campaign uses legitimate services like GitHub and FileZilla to distribute various malware, targeting Android, macOS, and Windows. The campaign, attributed to Russian-speaking threat actors, involves multiple malware variants, including RedLine, Vidar, and DanaBot. This method increases the efficiency of attacks by abusing authentic internet services.
Key Takeaways from Meeting Notes:
1. A multi-faceted cyber campaign, known as GitCaught, has been observed utilizing legitimate services like GitHub and FileZilla to distribute an array of malware variants including stealer malware and banking trojans to target Android, macOS, and Windows platforms.
2. Adversaries, likely Russian-speaking threat actors from the Commonwealth of Independent States (CIS), are behind the operation, and have been using fake profiles and repositories on GitHub to host counterfeit versions of well-known software in order to compromise devices and extract sensitive data.
3. The campaign involves malvertising and SEO poisoning to distribute malicious files embedded within various domains, and also includes the use of FileZilla servers for malware management and delivery.
4. The attacks are part of a larger campaign that aims to deliver multiple malware variants including RedLine, Lumma, Raccoon, Vidar, Rhadamanthys, DanaBot, and DarkComet RAT, with a notable infection pathway involving the redirection of victims to payloads hosted on Bitbucket and Dropbox, thus abusing legitimate services.
5. The Microsoft Threat Intelligence team has flagged the macOS backdoor codenamed Activator as a “very active threat”, noting its distribution via disk image files impersonating cracked versions of legitimate software and its ability to turn off macOS Gatekeeper and disable the Notification Center in order to steal data from specific wallet applications.
6. The campaign highlights the misuse of authentic internet services for cyber attacks and the reliance on multiple malware variants to increase its success rate, emphasizing the need for vigilant cybersecurity measures.
