A small business owner is configuring a domain for their website. They use their Gmail account as the registrant for the website; however, they do not check that account frequently. An attacker has been watching the small business owner and through footprinting the owner's social media, they brute$-$force their way into the Gmail account. The attacker then resets the password on the registrant account, changes the domain ownership, and removes all email records.
