Malware “court jester” attacks Facebook

IT security and control firm Sophos has warned users of Facebook to exercise care, following an attempt by hackers to infect computers by spreading messages containing malicious links on the popular social networking website. The recent attack comes in the form of Wall Messages left on Facebook users’ to view a video, but clicking on the link takes users to a site which urges them to download a file to watch the movie. Sophos says it detects the executable file as the Troj/Dloadr-BPL Trojan horse, which in turn downloads further malicious code (detected as Troj/Agent-HJX), and displays an innocent image of a court jester sticking his tongue out.
