NekoJB Jailbreak IPA

What is NekoJB Jailbreak?

The Kernel File Descriptor (KFD) exploit, which enables kernel memory read and write privileges up to and including iOS & iPadOS 16.6 beta 1, is currently being utilized to modify system files, much like the MacDirtyCow exploit was used on iOS & iPadOS 15.0-16.1.2. This leads to the question - can it be used for jailbreaking?

When KFD was initially discussed, its potential use in creating a jailbreak was highlighted, though concerns were raised about newer devices requiring a PPL bypass. However, good news for users of older devices: a developer has initiated a project to use KFD to create a jailbreak compatible with older arm64 devices, up to the iPhone X.

The project is led by HAHALOSAH, the developer behind the NoFreeAppLimit jailbreak tweak, with Mineek of the palera1n team lending their expertise in creating jailbreaks for older devices. Although palera1n is already available and can jailbreak almost any version of iOS or iPadOS on iPhone X or older, it is a semi-tethered jailbreak and requires a computer to return to a jailbroken state after every reboot. Users, particularly iPhone X users, also have to deal with the loss of SEP-related features such as Touch ID/Face ID, passcode, and Apple Pay.

A semi-untethered jailbreak based on KFD would offer older device users more convenience while jailbreaking, and would also provide unrestricted access to the above-mentioned SEP-related features, meaning no loss of Touch ID/Face ID, passcode, and Apple Pay functionalities.

HAHALOSAH announced in a post shared to /r/jailbreak on Saturday morning that the project is currently called nekoJB. However, it won't support arm64e devices due to the requirement of a PPL bypass that doesn't yet exist. Although a KFD-based jailbreak hasn't been achieved as yet, the post displays a screenshot of sandbox escape being achieved - a significant step forward.

The progress of the nekoJB project is certainly intriguing, as it holds the potential to provide a handy alternative to palera1n for those still using their arm64 devices.
