A Trojan virus named Koobface disrupt user activity on social networking site, Facebook, some time ago. Now, according to ScanSafe, Koobface has spread to other social networking sites. Koobface is a “message-generator” trojan, sending message to friends on social networks. It has been infecting Facebook’s, spreading via messages that told users to click a link that contains malware. Once a user click the link, then the user will be redirected to sites that contain malware, and then the users has already infected. Infected users will be very risky towards identity theft.

ScanSafe reported that the Trojan Koobface system has been infecting Bebo application, and will soon find other social networking sites such as Friendster, MySpace and BlackPlanet. “Users who click the link that contain Koobface Trojan will be greeted with a message that directs users to update their Flash Player to see a ‘video’. However, no actual video there or not necessary to update Flash player because all of that is only to get users sympathy so that Koobface will be more easily to install Trojan and infecting users system.” quoted Mary Landesman, senior security researcher at ScanSafe.

ScanSafe estimates that account used to block Koobface malware, although now only around 1 percent, but its development more quickly. “Suggestions, do not click link on suspicious or unexpected email, although the email is received from someone you known.” Landesman added.
