Xbox 360 Software Jailbreak Released Nearly 20 Years After Launch

The Peer Pressure softmod allows users to run unsigned code on the device.

A persistent software exploit, or softmod, called Peer Pressure has been released for the Xbox 360. It bypasses several system limitations on the console and runs unsigned code without requiring traditional hardware modifications.

To function, Peer Pressure modifies the console’s NAND image and hard drive security sector. During startup, the system initiates a sequence of DMA attacks, allowing the exploit to bypass restrictions on executing software code.

One of the main features of the softmod is removing digital signature restrictions on executable files. This enables the execution of homebrew applications and bypasses license and security checks for games and downloadable content.

Peer Pressure provides three boot modes that users can switch between to start the console in either a modified or standard state.

A built-in NAND write lock helps prevent unwanted changes that could cause the console to fail to boot.

Additional features of Peer Pressure include launching Xell and other Linux-like environments when turning on the console via the disc eject button, as well as loading third-party DLL libraries into games and applications. The latter function can be used to run RB3Enhanced or restore older Xbox 360 interfaces, including Blades and NXE.
