PyPatch

Inject arbitrary code into any running python interpreter

Supports all configurations of PyInstaller and PyArmor

---

Overview

pypatch includes:

• PyPatch injection executor to run a pre-packed python program and inject code at any time (before startup/after startup)

• Python injector library to run arbitrary code with any python3x.dll

• Process injector library to inject dlls

Usage

• Write the payload you want to inject in inject.py
• Compile a DLL with the payload with make dll
• Compile an injector (in cmd/injector) with your program and dll paths

Example

program.py obfuscated with pyarmor 8.4.2 and packed with pyinstaller 6.1.0

import time

def main():
  while True:
    print("Working")
    time.sleep(1)

if __name__ == "__main__":
  main()

Injecting inject.py with pypatch executor before startup

import os
print("Hello from inject.py!")
print = lambda *args, **kwargs: os.write(1, b"Boo!\n")
