What is checkra1n?
Based on the infamous checkm8 exploit, checkra1n is a tethered jailbreak tool designed for iOS 14. It is developed by Luca Todesco and the rest of the Kim Jong Cracks team.
The latest build brings support for iOS 14.0 as well as tvOS 14.0. However, support for newer devices seems to be limited at the moment. Only iPhone and iPad models with the A9/A9X chip are compatible at the moment.
Nevertheless, the developer team is working on adding support for iPhone 7, 7 plus, and other devices.
On the other hand, iPhone models with the A11 Bionic chip – iPhone 8, 8 Plus, and X – will be addressed in a future update.
The reason being that Apple uses a new mitigation technique in SEPOS on devices with the A10 chip and above. For instance, if you boot an iPhone in DFU mode and the SEP (Secure Enclave Processor) gets a request to decrypt user data, it causes a kernel panic.
While checkm8 is a powerful BootROM exploit, it does not affect the SEP. However, things have changed with the release of blackbird vulnerability, which allows an attacker to access the SEP. If all goes well, an update for A11 devices will go live soon.
Apart from iOS devices, checkra1n also supports the bridgeOS operating system of Apple’s T2 security chip.
Jailbreaking Apple’s security chip will be of little use for the average user, however.
Important: Refrain from using beta releases on your primary device. Beta and alpha builds should only be used on spare devices.
