Hacker group targets Sony in retaliation for lawsuit

The hacker group Anonymous has warned of a cyber attack against Sony, as retaliation for its suit against hackers George Hotz (aka "GeoHot") and Graf_Chokolo. The group calls the attack #OpSony, and calls it part of Operation Payback.

"Congratulations, Sony," the post read. "You have now received the undivided attention of Anonymous. Your recent legal action against our fellow hackers, GeoHot and Graf-Chokolo, has not only alarmed us, it has been deemed wholly unforgivable." The message accuses Sony of abusing the judicial system and violating user privacy. Cyber attacks by Anonymous have resulted in denial-of-service errors, and the group is under investigation by the FBI.

Though it may be unrelated, Kotaku notes that the PlayStation Network was down today for maintenance, and the PlayStation Blog and US PlayStation site have been intermittently unavailable today. We've contacted Sony for word on whether this is related to the threatened attacks.
