Python bindings for Microsoft DbgEng

Pybag provides helper functions on top of Python bindings for Microsoft Debug Engine to facilitate Windows native debugging.

Windows:

python setup.py install

Use Python's repl as a command shell if desired. Ctrl-c will break-in to the debugger if you are in a wait() call.

from pybag import *

def handler(bp, dbg):
    print("*********** BREAK")
    return DbgEng.DEBUG_STATUS_GO

dbg = UserDbg()
dbg.create("notepad.exe")
dbg.bp("Kernel32!WriteFile", handler)
dbg.go()

from pybag import *

def handler(bp, dbg):
    print("*********** BREAK")
    return DbgEng.DEBUG_STATUS_GO

dbg = UserDbg()
d.connect("tcp:server=192.168.1.10,port=5555")
dbg.create("notepad.exe")
dbg.bp("Kernel32!WriteFile", handler)
dbg.go()

from pybag import *

k = KernelDbg()
k.attach("net:port=50000,key=1.2.3.4")
