Microsoft now 'actively investigating' Surface jailbreak tool

Tools

Microsoft is now "actively investigating" the Jailbreak tool for Windows RT that surfaced last week, according to a report on The Register, and will take "appropriate action as necessary."

Though no further details were provided, this is a departure from Microsoft's (NASDAQ: MSFT) earlier stance where it played down the issue as not being related to security. "We applaud the ingenuity of the folks who worked this out and the hard work they did to document it. We'll not guarantee these approaches will be there in future releases," said Microsoft at that time.

The RT Jailbreak Tool allows users to run any software that is ported to the ARM-based Windows RT operating system, not just software from the official Windows Store. The tool leverages an existing flaw found in Windows to make running unsigned apps possible, utilizing the mechanism that was discovered and outlined in detail by security researcher C. L. Rokr in a post early last week.

At that time, Rokr pointed out that the inability to run Windows 8 code on the ARM-based Windows RT platform is nothing more than an artificial separation. Interestingly, he also highlighted the possibility of enforcing the code integrity checks in reverse on a Windows 8 device to see what Windows RT feels like.

Of course, the technique detailed in the original blog was beyond the reach of ordinary users--and probably many developers too. The RT Jailbreak Tool, on the other hand, works automatically and takes just 20 seconds to perform the jailbreak. The tool also makes its changes within the memory, which means that the changes are not permanent and will be restored upon a restart.
