# 설치 가이드

1. 코드 내려받기

git clone https://github.com/alfiecg24/KextRW

깃허브에서 프로젝트 코드 전체를 내 컴퓨터로 내려받습니다.

cd KextRW

방금 내려받은 프로젝트 폴더 안으로 이동합니다.

2. Make

보통 추천

사전 준비물

Git GitHub에서 프로젝트 코드를 내려받으려면 필요합니다.
Make Linux/macOS는 보통 기본 설치되어 있습니다. Windows는 별도 설치(예: MSYS2, WSL)가 필요합니다.

make

생성된 빌드 설정을 바탕으로 실제 컴파일을 진행해 실행 파일을 만듭니다.

✅ 에러 없이 끝나면 성공입니다. 생성된 실행 파일을 직접 실행해보세요.

# KextRW

A macOS kernel extension offering several features useful for security/vulnerability research against XNU.

The features provided by this kernel extension include:
* Virtual kernel read/write
* Physical read/write
* Getting the kernel base and slide
* Kernel memory allocation and freeing
* Kernel call primitive
* Address translation

The codebase is originally based on [IOKernelRW](https://github.com/Siguza/IOKernelRW), where you can find installation instructions, as they will be the same for this project. Any binary that wishes to create a userclient for this kernel extension must possess the `com.apple.security.alfie.kext-rw` entitlement. An easy-to-use test program can be found in the `tests/` folder, but the offsets and addresses are specific to my machine.

You can find the path to your kernelcache by running `kmutil inspect` - it will be printed at the top. This will be necessary if you would like to update the offsets and addresses in `kextrw_test.c`. I have not tested this on anything other than macOS 15.2.

Building the project using `make all` will output a static `libkextrw` library and a header file in the `build/` directory, which you can then use to build projects on top of the primitives provided by the kernel extension. The `kextrw_test.c` file in the `tests/` directory offers an example of this use case.
