Subdomain trick

Brand name placed in the left-hand labels of a host owned by someone else (login.brand.tld.other.tld).

How to spot it

  • Brand appears to the left of the real registrable domain
  • Long hosts with several dots

What to do

Apply the 4-step rule: ignore everything left of the last two labels; those two labels are the owner.

What the real thing looks like

  • Genuine subdomains like login.brand.tld
