Write-up

We logged into this level using the private ssh key and not the password so currently we don’t have the password. But we can take a look at the password(for Level 14 only)since we know all passwords are in etc/bandit_pass directory.

cat /etc/bandit_pass/bandit14

To submit the password to localhost I used nc command.

echo 4wcYUJFw0k0XLShlDzztnTBHiqxU3b3e | nc localhost 30000
