对80端口的信息收集没有太大收获，虽然心有不甘，哈哈。

看能不能破解这个无线WIFI的密码

破解成功,wifi的密码为p4ssword,
也许SSID以及这个密码同时也是ssh的密码

User dlink may run the following commands on localhost:

提权
dlink用户可以无需密码执行/usr/bin/TryHarder!
但是目标主机并不存在该文件，因此可以创建该文件，结果失败，没有权限创建该文件，需要另外想办法

成功提权！
本靶机主要的解决途径是通过破解无线报文，获得SSID和密码，而且假设这个SSID和密码同时也是系统的用户名和密码！
