A new version of the Koobface worm is making the rounds of Facebook this week, this time in the guise of an invitation to view a fake YouTube video. The link takes users to a page asking them to install an updated version of the Flash player, which is instead a piece of malware.
As Brian Krebs at The Washington Post reports, the user ends up with a Trojan on his machine.
In addition, the worm also hijacks the victim’s social networking account, by sending out additional invites in order to spread the worm to the victim’s friends and contacts. The worm currently is spreading across multiple networks, including hi5.com, friendster.com, myyearbook.com, bebo.com and livejournal.com.
See, this is the reason why I’m the one person on the planet not on Facebook.
