In today's video, I have pretty interesting news. Liang Chen of Keenlab team has published just a few hours ago a video in which he was demonstrating iOS 12.2 / 12.1.3 / 12.1.4 (as they are likely backward compatible) Jailbreak for the iPhone XS MAX (which is an A12 device), and thus the jailbreak is also compatible with the pre-A12 devices like iPhone 8, iPhone 7, iPhone 6 down to 5S. This is pretty big news because his jailbreak not only targets a firmware that is currently signed by Apple, but it also contains a PAC bypass.
PAC or Pointer Authentication Codes is a security mitigation technique introduced by Apple when they switched to armv8.3 architecture in the A12 chips used for iPhone XS, XR and XS MAX (and the new iPads). PAC is meant to protect the device from exploits based on ROP or JOP (Return-oriented programming and Jump-oriented programming). The first true PAC bypass for A12 devices was released by Brandon Azad of Google Project Zero a few months ago and it powers the Chimera Jailbreak on iOS 12.0 to 12.1.2, but rumors had it that the bypass was patched in iOS 12.1.3 or iOS 12.1.4 (although with no kernel exploit available, it's pretty hard to check).
Although #Keenlab team and Liang Chen aren't particularly known for releasing their jailbreaks, it does go to show that A12 devices are not as bulletproof as it was initially thought and the jailbreak community is far from giving up. While these devices do integrate new hardware mitigations which make jailbreaker's life a bit harder, it looks like there's always a way around that if you're willing to put the effort and the time in it.
