The majority of Americans, 63%, have been scammed online. 54% have had their social media account(s) compromised, and 49% have been victims of a data breach. Cyber criminals are becoming smarter and more professional; scams are often targeted and scammers impersonate companies or people you are already familiar with to gain your trust and take advantage of you.
Correction: A top-level domain comes after the last dot, not before it (e.g., com, org, net, etc.). For example with the URL, www.example.com, www is the subdomain, example is root domain, and com is the top-level domain.
