A simple keylogger for Windows written in Python using Pynput. May not work correctly on macOS/Linux.
Requirements: pip install pynput
You can rename keylogger.py to keylogger.pyw to run the keylogger in Ghost Mode, or keep the .py extension to keep the command window open. If you use .pyw, you must force stop "python.exe" from Task Manager once you're done.
