In February, Doctor Web virus analysts reported that the VSDC video editor’s download link had been compromised on the popular software platform CNET. Instead of the genuine program, visitors received a modified installer bundled with TeamViewer valid files and a downloader trojan that further retrieved malicious auxiliary modules from the repository. Thus, the computer was infected with a trojan from the BackDoor.TeamViewer family, which allowed attackers to establish an unauthorised connection to an infected computer, as well as with a script for bypassing Microsoft Windows’s built-in anti-virus protection. Utilising BackDoor.TeamViewer, the attackers were able to deliver payload modules with malware such as stealers, keyloggers and RAT to infected devices.
