What is typosquatting?

Typosquatting is registering a near-match of a brand's domain or handle — a transposed letter, a missing character, a swapped top-level domain — to catch people who mistype the real one.

It is a subset of cybersquatting distinguished by its method: it does not rely on anyone searching for the name, only on them getting it slightly wrong.

The common uses are phishing and credential harvesting, because a near-match domain makes a convincing sender address and a convincing login page. That makes the exposure a security problem rather than only a brand one.

Defensive registration is the usual answer for the highest-risk variants, on the basis that holding a name costs far less than contesting it later.
