Assisting Facebook’s security team efforts to purge the Koobface worm from the popular social-networking site, Microsoft added detection of the Koobface worm to the Malicious Software Removal Tool (MSRT). Since its release two weeks ago the newest version of MSRT has removed Koobface nearly 200,000 times from over 133,677 computers.
Koobface targets social networking sites and spreads by tricking users into responding to a message supposedly sent from one of their friends such as, “Check out this video.”
Clicking on links within these messages leads to a victim’s password and account information being stolen and the cycle continues as the account is then used to spread the infection to the user’s contacts.
The worm morphs with over 20,000 variations to date, as always it is important to keep security software up to date and not click on links willy nilly.
