Kenzer0 is a computer trojan that is spread across peer-to-peer networks and is programmed to monitor the browsing history of victims.[1]
The Kenzero trojan was first discovered on the November 27, 2009, but researchers think it went undetected for a few months prior to the initial discovery.[2]
Kenzero attacks computers that download files through peer-to-peer networks (P2P). Once the file is opened, the virus locates the victim's browsing history and publishes it online. People can then view the file(s).[3] [4] It then demands a fee for its removal.[5]
The virus hides inside video files of Hentai anime. It spreads via p2p networks.
