iOS 13 tfp0 Jailbreak Exploit Achieved!

In today’s video, I have great news for those of you who are interested in jailbreaking iOS 13 or the newest iPhone 11, iPhone 11 Pro or iPhone 11 Pro Max. Developer @iBSparkes known as Sparkey has successfully achieved tfp0 yesterday on his brand new iPhone 11 running iOS 13.0. According to Sparkey, he has achieved that in under 3 minutes. Pretty impressive. It goes to show that the Jailbreak community still has a chance, even when Apple’s innovative devices come with more and more security features.

What is a tfp0 kernel exploit?

A tfp0 kernel exploit is enough to be able to start updating Unc0ver Jailbreak to work with the iOS 13. Pwn20wnd may still need to figure out a way to update his PACless implementation, as iPhone 11, iPhone 11 Pro and iPhone 11 Pro Max has PAC just like the A12 devices, but with tfp0 that should only take a matter of days, maybe weeks if iOS 13 is significantly breaking the PACless implementation.

Jailbreak developers use tfp0 kernel exploits in order to achieve Read and Write capability over Kernel’s virtual memory. Once that is achieved, anybody can apply patches to become root, escape the iOS SandBox, defeat AMFI (Apple Mobile File Integrity), which handles CodeSign, and also CoreTrust (which works with AMFI to prevent jailbreak binaries from being executed without a valid Code Signing blob).

What does this mean for iOS Jailbreaking?

In order for tweaks to be able to run, Pwn20wnd would still need to update his PAC-less (Pointer Authentication Codes) Unc0ver Jailbreak, but it should be pretty easy at this point. Sparkey has also demonstrated Cydia running on iOS 13 Beta 1 back when the Beta 1 was seeded in the summer.

For the rest of the devices, @IBSparkes’ achievement basically guarantees a jailbreak on iOS 13 if he decides to release that. There is, however, no word about any releases for the moment, so that may not happen until after Apple has patched the bug if Sparkey goes through the responsible disclosure route.
