Security researchers are warning of a new variant of the Imuler Trojan for Mac OS X that specifically targets Tibetan activists.
"There have been a variety of droppers seen, the most recent of which purport to be group photos of Tibetan organizations," writes Intego's Lysa Myers. "This backdoor Trojan family was first discovered in September 2011 as a Mac PDF Trojan horse and has been targeting activist organizations with emails containing what appear to be pictures."
"The malware, a variation of the OSX/Imuler Trojan, which previously infected Apple computers with sexy photos and malicious PDFs, gives attackers remote control and the ability to download and steal sensitive files and information that could be used to commit fraud or extortion," writes TechNewsDaily's Ben Weitzenkorn.
"If your Mac was successfully infected by malware like this, you have effectively given remote control of your computer and your data to an invisible and unknown party," writes Sophos' Graham Cluley. "They could steal files from your Mac, spy on your emails, and plant further malware onto your systems. (It will be left as an exercise to the reader to come up with a shortlist of who might have an interest in breaking into the computers of Tibetan organisations)."
