Facebook’s 120 million users are being constantly targeted by a virus dubbed ‘Koobface’ that uses the social network’s messaging system to infect PCs and tries to gather sensitive information such as credit card numbers.

It is the latest attack by hackers increasingly looking to prey on users of social networking sites. Facebook spokesman Barry Schnitt mentioned in an e-mail that most of the viruses have tried to use Facebook in similar ways to propagate themselves as Koobface has. Koobface spreads by sending notes to friends of someone whose PC has been infected. Messages, with subject headers like, “You look just awesome in this new movie,” direct recipients to a website where they are asked to download what it claims is an update of Adobe Systems Inc’s Flash player. Once downloaded the users end up with an infected computer, taking them to contaminated sites when they try to use search engines from Google, Yahoo, MSN and Live.com, according McAfee.
