Koobface Worm - Now a threat for Linux and Mac users

While malware may be circulating less actively for Linux or Mac users, there are still threats and the need to always be careful.  Koobface (Facebook spelled backwards) has now been retrofitted so that these environments may also be infected if users are not careful.

QUOTE: A new variant of the Koobface worm that targets Mac OS X and Linux as well as Windows is spreading through Facebook, MySpace and Twitter, security researchers warned today. Antivirus firms first reported the malware, dubbed "Boonana," on Wednesday when Intego and SecureMac, two Mac-only security vendors, warned Mac OS X users that the worm was aimed at them.

Boonana spreads via messages posted to social networking or microblogging sites. Those messages bait the trap with the subject "Is this you in the video?" and a link to a malicious site. People who bite and click the link are then prompted to run a Java applet.
