The Witty Worm

Hack In The Box - 'Witty' Worm Wrecks Computers: "The 'Witty' worm writes random data onto the hard drives of computers equipped with the Black Ice and Real Secure Internet firewall products, causing the drives to fail and making it impossible to restart the PCs.

At least 50,000 computers have been infected so far..."
