Sony has stepped up its fight over recent PS3 exploits by filing for a restraining order against George "Geohot" Hotz, the "hacking group" fail0verflow and numerous other individual

Alleging that those involved have violated the US Digital Millennium Copyright Act and the Computer Fraud and Abuse Act, the firm is seeking a restraining order asking that all PS3 circumvention tools be taken offline and related computers be impounded.

Engadget points out that this isn't yet a lawsuit in the traditional sense as Sony hasn't filed a copyright infringement claim. The firm, it appears, simply wants the PS3 jailbreak and any information about it to disappear from the web, but that would seem to be only a short-term solution to the problem.
