Unix 14

In this challenge, you need to log in using the username pentesterlab and the password pentesterlab. The user root has left a backup of the home directory of users in a temporary directory, possibly /tmp or /var/tmp. Your task is to locate and extract the backup.gzip file and search for a file named credentials.txt which contains the password for the user victim.

Once you have the password, use the su command to become the user victim by running su victim. After successfully becoming victim, navigate to their home directory and search for the key to complete the challenge. Don't forget to clean up and remove any files you created during the decompression process.
