iOS 11.2.1 Has Been Jailbroken!

Security researchers at Alibaba’s Pandora Labs have successfully jailbroken the iPhone X on iOS 11.2.1. The news comes following the group’s untethered jailbreak of iOS 11.2.

“[Jailbreaking] is a very technical challenge and a peak for every iOS security researcher trying to climb.” says Long Lei, a security researcher who has reported seven vulnerabilities to Apple.

The Apple-implemented SMAP for iOS 11.1 is flawed and can be bypassed in a certain way. However, in the latest version, this issue has been fixed, which requires safety researchers to use other ways to solve the impact of SMAP . In addition, in older versions of iOS , security researchers could also trigger the kernel GC via the mach_zone_force_gc interface, or they could only populate the same type of data. But in iOS 11 , Apple disables the mach_zone_force_gc interface, so a new way to fire the kernel GC is needed.

Song Yang, head of Ali Secure Pandora Laboratories, says compared to other jailbreak in the past two years, Pandora Lab’s jailbreak is “perfect.”

“Although iOS 11.2 fixes some security issues, we confirmed on the day of release that the new version will still be able to jailbreak.” Song Yang said, “Although we soon escaped iOS 11.2 perfectly, we were limited to security research purposes, So it does not provide jailbreak tools. ”

While this jailbreak is unlikely to see public release, we’re hopeful that the recent exploits released by Ian Beer will lead to jailbreak for iOS 11.1.2. The exploit is also expected to result in a jailbreak for the Apple TV.
