Our fifth lab was focused on password cracking. We first created 6 users (useradd) and passwords (passwd) for each one using the sudo command, later creating a hash and utilizing a password cracking tool. Sudo allows the main user to execute commands as another user to modify or manage system services. A hash is used for password encryption, which we created for our users, then we ran the John the Ripper tool for 10 minutes to observe what could be cracked. The only thing cracked was my first user (user1) and its password (lucky). This was a fun lab that displayed how encryption protects data and the importance of creating strong passwords to decrease risks.
