【PyHacker编写指南】打造网站后台扫描器

这节课是巡安似海PyHacker编写指南的《打造网站后台扫描器》

包括如何处理假的200页面/404智能判断等

喜欢用Python写脚本的小伙伴可以跟着一起写一写呀。

编写环境：Python2.x

​

​

00x1：

需要用到的模块如下：

import request

00x2：

先将请求的基本代码写出来：

import requests


def dir(url):
    headers={'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/65.0.3314.0 Safari/537.36 SE 2.X MetaSr 1.0'}
    req = requests.get(url=url,headers=headers)
    print req.status_code


dir('http://www.hackxc.cc')

​

00x3：

设置超时时间，以及忽略不信任证书

import urllib3
urllib3.disable_warnings()
req = requests.get(url=url,headers=headers,timeout=3,verify=False)

再加个异常处理

调试一下

再进行改进，如果为200则输出

if req.status_code==200:
    print "[*]",req.url

00x4：

难免会碰到假的200页面，我们再处理一下

处理思路：

首先访问hackxchackxchackxc.php和xxxxxxxxxx记录下返回的页面的内容长度，然后在后来的扫描中，返回长度等于这个长度的判定为404

def dirsearch(u,dir):
    try:
        headers = {
            'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/65.0.3314.0 Safari/537.36 SE 2.X MetaSr 1.0'}
        #假的200页面进行处理
        hackxchackxchackxc = '/hackxchackxchackxc.php'
        hackxchackxchackxc_404 =requests.get(url=u+hackxchackxchackxc,headers=headers)
        # print len(hackxchackxchackxc_404.content)
        xxxxxxxxxxxx = '/xxxxxxxxxxxx'
        xxxxxxxxxxxx_404 = requests.get(url=u + xxxxxxxxxxxx, headers=headers)
        # print len(xxxxxxxxxxxx_404.content)


        #正常扫描
        req = requests.get(url=u+dir,headers=headers,timeout=3,verify=False)
        # print len(req.content)
        if req.status_code==200:
            if len(req.content)!=len(hackxchackxchackxc_404.content)and len(req.content)!= len(xxxxxxxxxxxx_404.content):
                print "[+]",req.url
            else:
                print u+dir,404
    except:
        pass

很nice

00x5：

再让结果自动保存

        dirsearch(url,dir)
