GeoSn0w's OpenJailbreak Project, an open-source iOS 11 to iOS 13 Jailbreak project & vault.

A WIP "Vulnerable by Design" kext for iOS/macOS to play & learn *OS kernel exploitation

An Open-Source iOS 11.0 -> 11.4.1 (soon iOS 13) Jailbreak, made for teaching purposes.

Research into porting the XNU kernel to ARM devices.

Welcome to Hoyt's SRD Repo for the Apple Security Research Device. Contribute Code or Open an Issue or Discussion.

A QEMU fork emulates D22AP/D221AP devices(iPhone X).

Research on Apple's USB protocols

Providing a great interface to the iOS kernel, hardware, threads and processes in a great research environment. (WIP)

PoC showing a method to hide syscalls on XNU (arm64 macOS and iOS) from static analysis

Checks macOS for Kernel Task Port. It may help detect intrusive kexts that would leak the kernel task.

Build your own complete XNU kernel header set, replaces Kernel.framework. Gain access to kernel private structures and symbols etc with IDE indexing worked.

iOS 12.0 -> 12.1.2 _kernproc and _rootvnode offsets for 16K devices

Kernel Fuzzer for Apple's XNU, mainly meant for the iOS operating system

A dump of some things from Jonathan Levin's newosxbook

Integration fork of QEMU focusing on XNU platforms (arm, aarch64, etc)

macOS kext, and userspace client to play with the zalloc kernel allocator.

Latest XNU Source from Apple.

Get p-state distribution and active frequency on Intel Macs without using IPG or kexts, by accessing /dev/xcpm
