Not only now Kernel exploits are harder to build (thanks to fewer exploit techniques being available), the post-exploitation for jailbreak purposes (i.e. This security mitigation introduced in A12 (iPhone XS / XR) has indeed added complexity to the jailbreak development. Pointer Authentication Codes (PAC) and iOS PAC is hardware-level security mitigation that prevents many common exploit techniques from being usable because the memory addresses on the device are tagged, thus eliminating the possibility to easily jump to the addresses you want. This is by no means an easy feat because every device after iPhone X, this means iPhone XS / XR, iPhone 11, iPhone 12, and iPhone SE 2020, have what is called PAC or Pointer Authentication Codes. The device that was successfully jailbroken was an iPhone 11 Pro. There’s also another, more important side to this story that many seem to miss. This is important because it represents the very first jailbreak to be achieved and demonstrated publicly for iOS 15 which is currently in Beta.

Based on this type confusion primitive, we will explore different ways to trigger other kernel memory corruption issues including UAF, overflow and out-of-bounds access, and also bypass the sandbox to access any Mach services on iOS.Īs such, we can see Pangu Team does have multiple Kernel exploits, including User-After-Free types.Īccording to the official MOSEC account on Weibo, Pangu Team has demonstrated a full iOS 15 Beta 4 jailbreak working on iPhone 11 Pro.
In this talk, we will continue to analyze this vulnerability and discuss its giant attack vector. The MOSEC 2021 speakers page states the following about the presentation by Tielei: The XNU is the kernel behind iOS, macOS, tvOS, iPadOS, and is giving his talk “Explorations of XNU Port Type Confusion.” #MOSEC2021 /3AjmWn6MG0 Tielei Wang, a Pangu Team member, had a presentation called “Exploitations of XNU Port Type Confusion”. This year, Pangu Team had its own member as a speaker. Pangu Team, together with PoC (Power of Community) organize the MOSEC conference (Mobile Security Conference) every year.

New iOS 15 Beta 4 Jailbreak Achieved by Pangu Team at MOSEC 2021 For iPhone 11 Pro The last public jailbreak released by the Pangu Team was the iOS 9.2 – iOS 9.3.3 64-Bit jailbreak which was semi-untethered. On iOS 9.3.3, however, Pangu Team has moved to the IPA-based jailbreaks, the same type that Unc0ver and Taurine Jailbreak are nowadays. The Pangu Jailbreak started as an untethered jailbreak for iOS 7 back on iOS 7.1.2 days, and it has since progressed. They are nowadays focused on security research and they still do iOS hacking, demonstrating a brand new jailbreak almost every year, and usually for the latest version of iOS. Pangu Team is a well-known security research group that has released multiple exploits and complete jailbreaks before, back on iOS 7, iOS 8, and iOS 9 times.
