The attack against KISS frontman Gene Simmons' website last year was one of the most bizarre campaigns in the history of the online vigilante group Anonymous. But the FBI is on the case and has raided the home of a Washington man thought to be involved in the attack.

Remember when Anonymous got mad at Gene Simmons last October? They were peeved that he urged entertainment companies to take a hard stance against piracy in a speech, saying "be litigious, sue anybody – take their homes, their cars, DON'T LET ANYBODY CROSS THAT LINE."

So, Anonymous, which hates copyright law almost as much as they hate Scientology, decided to take Gene Simmons' website down with a DDoS attack—a flood of traffic that overwhelmed the server. Gene Simmons reacted to the attack like Gene Simmons, posting a rant on his website claiming "we will sue their pants off" and "they might find their little butts in jail, right next to someone who's been there for years and is looking for a new girl friend." It seemed at the time that Simmons had no idea what the hell he was talking about and was inviting the full force of Anonymous to crash down upon his aging mane. But Simmons might have the last laugh.

Nobody has been arrested, but the FBI did raid the home of a Gig Harbor, Washington man, according to a recently unsealed search warrant reported by the Seattle Times. The feds used records provided by Simmons' lawyer to determine that a computer from the home had participated in the attack—reloading Simmons' website more than 48,000 times in 47 minutes. The guy whose home was raided must be sweating: DDoS attacks, though they can be initiated with the click of a button, are punishable with up to 10 years in prison. And the Feds apparently have strong proof that this guy was directly involved in attacking Simmons' site, unlike in their clueless probe that earlier this year swept up people involved in the perfectly legal pursuit of running Anonymous' chat servers.

The members of the KISS Army must be fist-pumping like crazy in their beat-up Camaros.
