The instance shows the information for connecting to the remote server via SSH. No additional clues other than the description was given.
The syntax for connecting to SSH server through a given port is:
ssh -p <port> <username>@<website URL>
The tool that automates tasks to run at set intervals in linux is usually cron. The crontab file is at /var/spool/cron/crontabs. Trying to access this file gave me a warning as I lack user privilege as a picoCTF player to see the crontab file.
However, upon surfing through some of the directories, I have found an interesting hack in the form of a custom directory, named “challenge” in the root of the file system.
The /challenge directory contains a file named ‘metadata.json’ that holds the flag as its content.
