Inject-Dylib

ObjC Code to Programmatically Perform Dylib Injection. Code leveraged from Wojciech Regula's FirefoxStealer project (https://github.com/r3ggi/FirefoxStealer).

Steps:

1. Build your injection dylib to do whatever function you desire (ex: pop calc, print text to stdout, etc.)
2. In the Inject-Dylib main file, edit the binpath variable value and enter the path to the application you want to inject into
3. In the Inject-Dylib main file, edit the maliciousDylibPath variable value and enter the name of the injection dylib you want to use
4. Build the Inject-Dylib project (by default Xcode will drop the binary to ~/Library/Developer/Xcode/DerivedData/Inject-Dylib-[random]/Build/Products/Debug)
5. Place your injection dylib in the same folder as the Inject-Dylib binary

6. ./Inject-Dylib

I included a sample dylib that opens calc if the injection is successful.
