Windows RT jailbreak tool can run unsigned program

Two days ago we reported that security researcher clrokr has developed a temporary jailbreak method for Windows RT, allowing Microsoft's ARM operating system to run unsigned, ARM-based Desktop program. Now, another programmer has also released his Windows RT automatic jailbreak tool.

The tool's creator is "netham45″, which was released on the XDA Developers website earlier today. This tool mainly runs an unsigned desktop program on Windows RT by modifying a specific part of the Windows RT system kernel to allow the user to change the minimum signature level of the system.

Microsoft previously said that it "always applauded for this clever approach," but they pointed out that this jailbreak needs to be done every time Windows RT starts, and will no longer exist after the reboot. This is because the operating system's UEFI secure boot process currently holds the lowest signature level on a permanent basis. Microsoft also said that this model "…" is not a security vulnerability, and does not pose a threat to Windows RT. More importantly, Microsoft may be looking for ways to turn off this vulnerability in Windows RT, even if it is not a high-risk vulnerability.
