把主要的文件查看了一下,其中一个文件 WPA-01.cap引起注意,看能否下载到本地

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

dlink@victim01:/usr/bin$ sudo -l
User dlink may run the following commands on localhost:
    (ALL) NOPASSWD: /usr/bin/TryHarder!

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!
