Koobface is a computer worm infection that takes advantage of users through social network messages in Facebook, Twitter, MySpace and others. Koobface attacks social network user’s profiles by sending a message asking them to view videos which redirects users to malicious websites designed to spread the Koobface infection. Many of the illicit messages sent via social networks have the subject line "You look funny in this new video" or "You look just awesome in this new movie." If the link within the message is clicked on, then it will ask that you update your flash player which leads to the download of malware. Koobface is able to infiltrate a users' system through a fake flash player update file named flash_player.exe. Other variants of Koobface are known as W32.Koobface, W32/Koobface, Worm.Win32.Koobface.b and Boface.
