Seems like some less than desirable people in Japan have created a virus that infects people who use a popular P2P file sharing service called Winni. It is called Kenzero and installs itself after users have downloaded an illegal game called Hentai. It then asks for personal information to launch the game and grabs that info to post on a public website. Then it blackmails the user into paying to remove your name.

If this doesn't catches on with undesirables who go after porn users, it will be a miracle. Sounds like trouble brewing here.
