A latest buildable and debuggable Objective-C runtime (objc4-818.2) project.

Run iPhone (xnu-arm64) in a Docker container! Supports KVM + iOS kernel debugging (GDB)! Run xnu-qemu-arm64 in Docker! Works on ANY device.

Bidirectional XPC message interception and more. Powered by Frida

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

XNU kernel, Kernel Collection and CodeQL build scripts

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.

GeoSn0w's majestic knowledge base for iOS 12 / iOS 13 Jailbreak Development.

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.

A script for automatically compiling xnu and it's dependencies works for 10.13 High Sierra+ source code from Apple Inc.

CodeQL + DTrace = Memory Disclosure Vulnerabilities in XNU

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

Sniff XPC communication using Frida and Go

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

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