Below are the practical aspects that are included in this course, giving you a chance to put the knowledge you’ve learned into practice, and gain some hands-on experience.

Google Dorks, also referred to as Google Hacking, are a great way to create search queries that can find very specific content, such as admin login pages, or perform red team recon activities to identify old subdomains that could be an entry points into the target company.
