Koobface is a computer worm that targets users of the social networking websites Facebook (its name is an anagram of "Facebook"), MySpace, hi5, Bebo, Friendster and Twitter. Koobface is designed to infect Microsoft Windows and Mac OS X, but also works on Linux (in a limited fashion). Koobface ultimately attempts, upon successful infection, to gather login information for FTP sites, Facebook, and other social media platforms, but not any sensitive financial data. It then uses compromised computers to build a peer-to-peer botnet. A compromised computer contacts other compromised computers to receive commands in a peer-to-peer fashion. The botnet is used to install additional pay-per-install malware on the compromised computer as well as hijack search queries to display advertisements. It was first detected in December 2008 and a more potent version appeared in March 2009. A study by the Information Warfare Monitor, a joint collaboration from SecDev Group and the Citizen Lab in the Munk School of Global Affairs at the University Toronto, has revealed that the operators of this scheme have generated over $2 million in revenue from June 2009 to June 2010.
