 # Pupy
 Pupy is an opensource, cross-platform (Windows, Linux, OSX, Android), multi function RAT (Remote Administration Tool) and post-exploitation tool mainly written in python. It features an all-in-memory execution guideline and leaves very low footprint. Pupy can communicate using various transports, migrate into processes (reflective injection), load remote python code, python packages and python C-extensions from memory.  
 Pupy modules can transparently access remote python objects using rpyc to perform various interactive tasks.
