Sony has been granted a temporary restraining order against George Hotz and the hacking group fail0verflow after they published root key details and cracks for the PlayStation 3.
The injunction means George Hotz can no longer put information on the web about the hack and must hand over his computers to Sony.
He has 10 days to comply with the Californian court order to hand over his computer equipment.
The court order comes despite scepticism that Sony could pursue those behind the PS3 hack in California.
It’s only the first step for Sony, but it has proven to the court that PlayStation 3 jailbreaks can cause ongoing harm to the business. Although Hotz is forbidden from distributing the crack, it is still widely available over the internet.
