MacDefender leaps onto Facebook

In a desperate attempt to capture more victims before the latest Apple update kills MacDefender and MacGuard dead once and for all (for now anyway) the Mac malware has made the leap to Facebook and is now spreading virally, claiming to be a video of IMF boss Dominique Strauss-Kahn.
The malware is using a technique called clickjacking to spread. A message appears in your timeline apparently posted by one of your friends, in this case referring to the news story of IMF chief Dominique Strauss-Kahn who is facing charges in New York over charges of rape. You are then invited to click a link to view a story or in this case a video. Instead of opening anything however the malware download is triggered. Finally the message you received is now posted on your timeline to catch the next unwary viewer.
Security firm Sophos has the full details
Needless to say, if you see this on Facebook, don’t click on the link!
Windows users beware: The same video is also being currently used to spread the Windows Zeus botnet to Microsoft machines.
