NullTrace-Android-Injector

Inject shared libraries on any process in android

Successful shared library injections tested on real devices and emulators (handles nativebridge for arm lib injections on emulator)

Building:

1: Get the Android-NDK: https://developer.android.com/ndk/downloads?hl=en and make a new environment variable called NDK and link the root NDK directory to it, Or manually adjust the NDK and CMake_Toolchain paths here: Link NDK Link CMAKE_TC

Install CMake and Ninja and make sure the Path for both is set
https://cmake.org/download/ https://ninja-build.org/

2: On Windows: run the build.bat file in powershell by: .\build.bat

On Unix: chmod +x build.sh and run the build.sh file by: ./build.sh or bash build.sh or sh build.sh

3: The executables will be inside build_out/{arch}/NullTrace-Injector

Running:

su
chmod 777 NullTrace-Injector
chmod 777 (libraryname).so
./NullTrace-Injector -p (packagename) -lib (library path)

flags:

-p flag : provide package name like com.nullbit.pocinject
-lib flag : provide full library path like /data/local/tmp/libhacklib.so
