A new version of the Koobface worm is making the rounds of Facebook this week. The link takes users to a page asking them to install an updated Flash player, which is instead a piece of malware. The worm also hijacks the victim s social networking account, by sending out additional invites in order to spread the worm to the victims friends and contacts. The worm currently is spreading across multiple networks, including hi5.com, friendster.com and bebo.com.
