Typosquatting

Typosquatting is the registration of domains that differ from a real domain by a typo, a swapped or extra letter, a hyphen or another TLD, to catch mistyped visits and to make phishing links look familiar.

How it works

Variants are produced systematically: omission, repetition, transposition, keyboard-neighbour replacement, added words such as -login or -support, and alternative TLDs.

The same lists are used defensively: monitoring which variants of a brand domain get registered and start resolving.

Example from the PhishDestroy database

How to protect yourself

  • Watch the exact spelling and TLD of sites that handle money or logins.
  • Brand owners can generate variants of their domain and monitor new registrations.
