Here are some detailed instructions on how to install pydbg.
In its most basic form, you need the following to execute a program:
from pydbg import *
from pydbg.defines import *
def exception_handle(dbg):
print(dbg.dump_context())
raw_input("Press enter to continue...")
return DBG_EXCEPTION_NOT_HANDLED
def debug(exe_path, params):
dbg = pydbg()
pid = dbg.load(exe_path, params)
dbg.set_callback(EXCEPTION_ACCESS_VIOLATION, exception_handle)
dbg.set_callback(EXCEPTION_GUARD_PAGE, exception_handle)
dbg.run()
return
def fuzz(exe_file):
while <cond>:
<prepare the parameters>
#debug the program and stop when there's a crash
debug(exe_file, params)
