With Koobface spreading throughout social networking sites, Twitter has taken action by suspending accounts known to be infected with Koobface malware.  Koobface takes control of logged in social network sites to post messages on behalf of the victim to convince friends to click on a link.  These links direct the friends to malicious websites that attempt to infect the visitor.  Koobface also attacks users on Facebook and MySpace using similar techniques.  Previous variants of Koobface have attacked Bebo, Friendster, LiveJournal, and Hi5 according to CERT.
Previously Koobface would use trending topics like Michael Jackson to fool users to click on links to malicious sites when the link advertised a Michael Jackson video.  Koobface is being developed on a regular basis to bypass security software and avoid detection.  Koobface is also able to obtain data from infected users machines and is considered a dangerous threat.
