pymemimporter

pymemimporter is a funny PoC that allows you to import any .pyd from memory with only pure python code (no .pyd) !

It basically executes a shellcode with ctypes to add _memimporter (from py2exe project) as a builtin python module :D

based on Joachim Bauch's MemoryModule (https://github.com/fancycode/MemoryModule) and Didier Stevens' ShellCodeMemoryModule (https://blog.didierstevens.com/programs/shellcode/)

Only implemented for python 32bit on Windows

usage:

C:\Users\me\Desktop>python.exe
Python 2.7.11 (v2.7.11:6d1b6a68f775, Dec  5 2015, 20:32:19) [MSC v.1500 32 bit (Intel)] on win32
