Native code execution

The native_function submodule
"""""""""""""""""""""""""""""
.. automodule:: windows.native_exec.native_function
:members: create_function
Simple machine code generation
""""""""""""""""""""""""""""""
These modules allow you to write some simple x86 / x64 shellcode. This is useful to use in adequation to :func:`create_function`.
The instruction name are as explicit as possible with the following convention:
* This is `intel syntax` so `dest, src`
* X specify a value passed as parameters::
Mov_EAX_X(0x42) # mov eax, 0x42
* D is for `dereference`::
Mov_EAX_DX(0x42424242) # mov EAX, [0x42424242]
Mov_DEAX_EDI() # mov [EAX], EDI
All instructions follow this interface:
.. py:class:: Instruction
.. py:method:: get_code(self)
:returns: :class:`str`: The raw code of the instruction
.. py:method:: get_mnemo(self)
:returns: :class:`str`: The mnemonic of the instruction
Example::
import windows.native_exec.simple_x86 as x86
i = x86.Mov_EAX_X(0x42434445)
i.get_code()
# '\xb8EDCB'
i.get_mnemo()
# 'mov EAX, 0x42434445'
You can also use a :class:`MultipleInstr` instance to merge instructions
Example::
import windows.native_exec.simple_x86 as x86
code = x86.MultipleInstr()
code += x86.Mov_EAX_X(0x42434445)
code += x86.Push_EAX()
code += x86.Ret()
code.get_code()
# '\xb8EDCBP\xc3'
print(code.get_mnemo())
# mov EAX, 0x42434445
# push EAX
# ret

IAT Hooking
"""""""""""
.. _hook_protocol:
The hook protocol
-----------------
Callback arguments
''''''''''''''''''
A hook callback must have the same number of argument as the hooked API, PLUS a last argument `real_function`.
The `real_function` argument is a callable that represent the hooked API, it can be called in two ways:
* Without argument, the call will be done with the argument originaly passed to your callback. This allow simple redirection to the real API.
* With arguments it will simply call the API with these.
Example::
def createfile_callback(lpFileName, dwDesiredAccess, dwShareMode, lpSecurityAttributes, dwCreationDisposition, dwFlagsAndAttributes, hTemplateFile, real_function):
print("Trying to open {0}".format(lpFileName))
if "secret" in lpFileName:
return 0xffffffff
# Perform the real call
return real_function()
.. _type_information:
Type information
''''''''''''''''
In order make the magic behind Python Hook Callback, :mod:`ctypes` need to have type information about the API parameters.
There is (again) two ways to give those informations to your hook callback. Both techniques use a decorator to setup type information to the callback.
* Giving the type manualy using the decorator :class:`windows.hooks.Callback`::
from windows.hooks import *
# First type is return type, others are parameters types
@Callback(ctypes.c_void_p, ctypes.c_ulong)
def exit_callback(x, real_function):
print("Try to quit with {0} | {1}".format(x, type(x)))
if x == 3:
print("TRYING TO REAL EXIT")
return real_function(1234)
return 0x4242424243444546
* Using the `Callback` decorator generated from known functions::
from windows.hooks import *
# Decorator name is always API_NAME + "CallBack"
@CreateFileACallback
def createfile_callback(lpFileName, dwDesiredAccess, dwShareMode, lpSecurityAttributes, dwCreationDisposition, dwFlagsAndAttributes, hTemplateFile, real_function):
print("Trying to open {0}".format(lpFileName))
if "secret" in lpFileName:
return 0xffffffff
return real_function()
.. note::
See the list of known functions
Put the hook
------------
To setup your IAT hook you just need:
* A callback that respect the :ref:`hook_protocol`
* The :class:`IATEntry` to hook
You just need to use the function :func:`IATEntry.set_hook`
Full Example::
import windows
from windows.hooks import *
@CreateFileACallback
def createfile_callback(lpFileName, dwDesiredAccess, dwShareMode, lpSecurityAttributes, dwCreationDisposition, dwFlagsAndAttributes, hTemplateFile, real_function):
print("Trying to open {0}".format(lpFileName))
if "secret" in lpFileName:
return 0xffffffff
return real_function()

imp = my_exe.pe.imports
iat_create_file = [entry for entry in imp['kernel32.dll'] if entry.name == "CreateFileA"]

Remote Python Injection
***********************
It's possible to inject the python interpreter into remote process. All you need to do is to use the method :func:`windows.winobject.WinProcess.execute_python`.
Calling this function will trigger the interpreter injection and the python code execution.
For simpler interaction interaction with the remote python, you can an RPC master linked to the remote interpreter.
RPython 101
'''''''''''
RPython is a very simple Pythonic (I hope so) RPC slave-master. It's goal is to allow easy manipulation of a remote interpreter.
The only action up to the `slave` is the creation of it's `name_pool`: a namespace of object accessible by the `master`.
After that the `slave` will just wait for request and return the desired object.
All slave object seen by the master are proxy that redirect operation to the slave.
RPython RPC to remote process
'''''''''''''''''''''''''''''
For easy manipulation of a remote Python interpreter, you can use the RPCInjection module::
import windows
import RPCInjection
calc = [x for x in windows.system.processes if x.name == "calc.exe"][0]
master = RPCInjection.launch_remote_slave(calc)
# Master is a RPC-master to a python interpreter in calc.exe
master['windows']
# <RemoteObj |<module 'windows' from 'C:\Users\hakril\Documents\Work\PythonForWindows\windows\__init__.pyc'>|>
# This is a way to get our own (python.exe) pid
windows.current_process.pid
3624
# This is a way to get the pid of calc.exe
master['windows'].current_process
# <RemoteObj |<windows.winobject.CurrentProcess object at 0x055E6250>|>
master['windows'].current_process.pid
5052
# We can also play with the peb of the remote process
master['windows'].current_process.peb
# <RemoteObj |<windows.winobject.PEB object at 0x054A3DF0>|>
master['windows'].current_process.peb.commandline
# <RemoteObj |<WinUnicodeString ""C:\Windows\SysWOW64\calc.exe" " at 0x55e9850>|>
# we can import new stuff
x['json']
# ...
# RPython.exchange.RemoteKeyError:
# ....
# KeyError: u'json'
x.imp('json')
# <RemoteObj |None|>
x['json']
# <RemoteObj |<module 'json' from 'C:\Python27\Lib\json\__init__.pyc'>|>
.. note::
The slave `name_pool` in RPCInjection is filled with :mod:`windows`, :mod:`__import__`, :mod:`ctypes` and :mod:`self` (the RemotePythonSlave object)
