Bandit Level 21 → Level 22

Level Goal

A program is running automatically at regular intervals from cron, the time-based job scheduler. Look in /etc/cron.d/ for the configuration and see what command is being executed.

Commands you may need to solve this level

cron, crontab, crontab(5) (use “man 5 crontab” to access this)

🔑 Solution

ssh bandit21@bandit.labs.overthewire.org -p 2220

Then enter the password obtained from the previous challenge.

We started by navigating to the /etc/cron.d directory, where we discovered an interesting file named cronjob_bandit22. We then used the cat command to inspect its contents. We came across an intriguing script located at /usr/bin/cronjob_bandit22.sh.

We ran cat again to read the script; it appears to write the bandit22 password to a strangely named file in /tmp.

Once again, we used the cat command to display the contents of the file located in the /tmp directory.

Great job! That’s the flag you’ll need for the next challenge.
