hi

test this sample code :
def detect_overflow(dbg):
if dbg.dbg.u.Exception.dwFirstChance:
return DBG_EXCEPTION_NOT_HANDLED
print "Access Violation Happened!"


def startdbg():

dbg = pydbg()
dbg.load("target.exe")
dbg.set_callback(EXCEPTION_ACCESS_VIOLATION, detect_overflow)
dbg.run()
if __name__ == '__main__':
startdbg()

Thanks netw0rm for reply.

dbg = pydbg()
dbg.load("target.exe",sample_file)

I am using above code in my fuzzer but the issue is target application get started by the debugger but the sample_file is not load.

Thanks

hi phreak , you must enter your path samplee file with \\  , see a sample in follow :

dbg.load("C:\\Program Files\\r2 Studios\\Xion\\Xion.exe","C:\\Documents and Settings\\netw0rm\\Desktop\\lol.m3u")
