HTTP暴力破解、撞库,有一些惯用的技巧,比如:
1. 在扫号人人网时,我遇到单个账号错误两次,强制要求输入验证码,而对方并未实施IP策略。
我采用维护10万(用户名,密码) 队列的方式来绕过验证码。具体的做法是,当某个用户名、密码组合遇到需要验证码,就把该破解序列挂起,放到队列尾部等待下次测试,继续破解其他账号密码。
这样就可以保证2/3的时间都在进行正常破解和扫号。
2. 在破解美团网某系统账号时,我遇到了单个IP访问有一定限制,请求频率不可过快。于是我挂了72个 HTTP代理来解决这个问题。 看似每个IP的请求都正常,但其实从整个程序上看,效率还是挺可观的。
本篇我发出自己抓HTTP的脚本片段,其实只有几行。匿名代理是从这里抓取的:http://www.xici.net.co/nn/
首先获取代理列表 :

from bs4 import BeautifulSoup import urllib2 of = open ( 'proxy.txt' , 'w' ) for page in range ( 1 , 160 ): html_doc = urllib2.urlopen( 'http://www.xici.net.co/nn/' + str (page) ).read() soup = BeautifulSoup(html_doc) trs = soup.find( 'table' , id = 'ip_list' ).find_all( 'tr' ) for tr in trs[ 1 :]: tds = tr.find_all( 'td' ) ip = tds[ 1 ].text.strip() port = tds[ 2 ].text.strip() protocol = tds[ 5 ].text.strip() if protocol = = 'HTTP' or protocol = = 'HTTPS' : of.write( '%s=%s:%s\n' % (protocol, ip, port) ) print '%s=%s:%s' % (protocol, ip, port) of.close() |
接着验证代理是否可用,因为我是用于破解美团网系统的账号,因此用了美团的页面标记:
