haystack 0.17

haystack is a Python module to search C structures in a process' memory.

What does it do?:

The basic functionnality is to search in a process' memory maps for a specific C Structures.

How do it knows that the structures is valid?:

You add some constraints ( expectedValues ) on the fields. Pointers are also a good start.

Where does the idea comes from?:

use http://www.hsc.fr/ressources/breves/passe-partout.html.fr  to get keys
use http://pauldotcom.com/2010/10/tsharkwireshark-ssl-decryption.html
 or http://www.rtfm.com/ssldump/ to read streams
use scapy, because it's fun ? but we need IP reassembly .
pynids could be more useful...
dsniff is now in python ?
flowgrep
use python.

HOWTO:

>>> import haystack
>>> haystack.findStruct( pid , 'ctypes.c_int')
>>> haystack.findStruct( pid , 'ctypes_example.big_struct')

It's easy to add new structures (check ctypeslib or do it by hand).
