In December, a group of hackers who call themselves failOverflow released a package of software that allows pirated games to be run on the PS3.

On Tuesday, Sony filed a lawsuit against failOverflow asking for a temporary restraining order to block the distribution of the package. FailOverflow posted on Twitter that their goal was to “be able to run Linux with dual-boot into GameOS, without 3D restrictions, on every PS3 currently out there” and not to encourage the use of pirated games.

Sony claims that the tools released violate U.S. copyright law, including the Digital Millennium Copyright Act and the Computer Fraud and Abuse Act.

The programs that are in the package include Metldr Keys, dePKG Firmware Decrypter, 3.55 6 Firmware Jailbreak code and Signing tool which allow access control, encryption and digital signature protection in the PS3. Games that are authorized to run on the PS3 have a unique digital signature which is not present on pirated games. With this package, the user can execute code that will enable the pirated games to run.
