Facebook's millions of users are in the crosshairs of a computer virus dubbed Koobface that is being spread through the social networking site's messaging system.
Users whose computers are infected may have their credit card numbers stolen or their searches on Google, Yahoo and MSN diverted to fraudulent Web sites.
The malicious code underscores how hackers are increasingly targeting social networking sites including Facebook and MySpace to capitalize on their big audiences. Because social networking sites allow messages only between fellow members who are confirmed friends, many users assume they are safe.
