|

It has 2 ports one is for ftp and other is for ssh.

|

## FTP

|
||||
|
||||
Now we can read any file directly because there is no command to view files so we can download that flag file and read it later.
|
||||

||||

|
||||
|
||||
Now we came to find a folder called "noread" in which there are 2 key files.
|
||||
|
||||

|
||||
|
||||
|
||||
We downloaded those files and now we have to crack "private.asc".
|
||||

|
||||
|
||||
Using johntheripper's gpg2john we can crack the key
|
||||
|
||||

|
||||
|
||||
Now we know that password for "backup.pgp" is "xbox360" we are going to decrypt "backup.pgp" using this password.
|
||||

|
||||
|
||||
We now have obtained the root hash , now we just have to crack it.
|
||||

|
||||
|
||||
## SSH
|
||||
|
||||
Now we ssh into the box with username "root" and password "hikari"
|
||||
|
||||
<a href="https://imgur.com/D93cCzl"><img src="https://i.imgur.com/D93cCzl.png" title="source: imgur.com" /></a>
|
||||
|
||||
Now read "root.txt" and submit that flag to complete the CTF.
