Facebook Christmas Worm Spreads Holiday Infection — InformationWeek.
PandaLabs, the research arm of anti-malware company Panda Security, says that a variant of the Koobface worm, Koobface.GK, is being spread through the posting of malicious links of Facebook wall pages.
Attempting to play the video or to click on the links on the page leads to an infection attempt, which will compromise the victim’s computer if successful.
The links take Facebook users to a fake embedded video player that offers a Christmas greeting, in keeping with the tendency of cybercriminals to try to exploit current or seasonal events.
