Submission + - Windows RT jailbreak smash: Run ANY app on Surface slabs (theregister.co.uk)

iComp writes: "The security mechanism preventing unauthorised software running on ARM-powered Windows RT tablets — such as Microsoft's Surface slabtops — can be easily defeated.

The Redmond giant wanted only cryptographically signed executables, ideally those obtained from the official Windows application store, to run on its hardware. But, we're told, by twiddling a byte of memory in the Windows kernel, it is possible to disable the protection system and allow any code to run on the system.

Taking full control of the device, effectively jail-breaking the computer to run any ARM-compatible software, after that point is an exercise left to the user.

A security researcher calling him or herself C. L. Rokr claims to have found an oversight in the Windows kernel to allow this to happen. According to Rokr, all you have to do is fire up the Windows Debugger software with Administrator-level permissions, connect it to the tablet and manipulate the device's kernel memory."
