PlayStation 3 Jailbreak


PlayStation 3 Jailbreak was the first USB chipset that allowed unauthorized execution of code, similar to homebrew, on the PlayStation 3. It works by bypassing a system security check using a memory exploit which occurs with USB devices that allows the execution of unsigned code.

Exploit

The underlying exploit and inner workings of the PlayStation 3 Jailbreak have been entirely reverse engineered and reimplemented through the open source .
Through analysis of USB traffic to and from the PS3 Jailbreak, it was found that the device induced a heap overflow in kernel-space memory to trigger execution of untrusted code.

Legality

Sony had taken a few steps to prevent the jailbreak of the PlayStation 3, and has associated the action as a form of copyright infringement. In eastern European countries, no action has ever been taken to condemn such cases.
The cases listed below are lawsuits Sony filed in courts to prohibit the sales and imports of circumvention devices that would jailbreak the system.
