Since we have access to ftp through "anonymous" login we can upload a php reverse shell.

## PORT 21

We can grab the task.txt through "get" command.

We also found a list of passwords so that we can use it in brute forcing.

## PORT 22

By looking at the text file we can check if "lin" is a user on that box so we can bruteforce our way in through ssh by using hyrda.

```
hydra -l lin -P locks.txt ssh://$IP -t 4
```
$IP is nothing but a variable for bash environment , export IP=10.10.187.202.

We found the password for "lin".

We can root the box through "/bin/tar" we can find exploit to it by visiting GTFOBINS.

We are now root and we can read that root.txt flag in order to complete the CTF.
