Pyjacker

Pyjacker

Pyjacker is a little framework to hijack library functions and create hooks in python language.

Instructions

• Create your hooks python module, for example:

from ctypes import * import pyjacker

libc = CDLL('libc.so.6')

@pyjacker.hook('ssize_t write(int fd, const void* buf, size_t count)', ctypes_ret_type=c_long, ctypes_args=(c_int, c_void_p, c_ulong)) def write(fd, buf, count): print "hooking write" print fd print buf print count

return libc.write(fd, buf, count)

if name == "main": import sys pyjacker.launch(sys.argv[1:], file)

• Launch your hooks file with your program and its args:

$ python hooks.py program arg1 arg2
