Porn malware blackmails victims
By Edward Berridge
A FORM OF MALWARE has been seen in the wild which sniffs and publishes the user's net history on a public website before demanding a fee for its removal.
The Japanese trojan Kenzero installs itself on computers using a popular filesharing service called Winni.
It mysteriously targets those who download illegal copies of Hentai, which are pornographic cartoon games. It requests the victim's personal details as part of the download process.
It then takes screengrabs of the user's web history and publishes it online in their name, before sending an e-mail or pop-up screen demanding a credit card payment of 1,500 yen (£10) to "settle your violation of copyright law" and remove the webpage.
Many victims have paid up in Japan where a loss of honour is often viewed as an unbearable humiliation..
