The PS3 was reportedly cracked wide open recently and Sony has said in a statement to Edge that they are intent on dealing with it. And dealing with it they are, Sony are biting back at the hackers, not so much on the soft or hardware side, but legally.
Sony is apparently seeking a temporary restraining order against everyone involved with cracking the PS3 open, ordering that all devices that circumvents the PS3 protection system taken offline and restricting the hackers from accessing the console.
The motion argues that the individuals and whatever devices involved violates the Digital Millennium Copyright Act and the Computer Fraud and Abuse Act for supposedly knowing that cracking the PS3 would open it up to piracy.
