Lookalike Domains and Typosquatting: How Fake Websites Imitate Real Brands
How attackers use misspellings, extra words, and lookalike characters to make domains feel familiar.
What lookalike domains do
Lookalike domains imitate familiar brands by changing letters, adding words, using unusual TLDs, or hiding the brand inside a longer hostname.
Typosquatting patterns
Common patterns include missing letters, swapped letters, numbers replacing letters, and support or billing words added to a brand.
Homoglyph and punycode risk
Some characters look similar across alphabets. Punycode can represent internationalized domains, but attackers may abuse visual similarity.
Business impact
Brand impersonation can lead to fake login pages, payment fraud, customer support scams, and trust damage. Customers may blame the real brand after a bad experience.
What CheckLink checks
CheckLink can identify basic lookalike patterns and punycode signals today. Brand monitoring is a planned beta for broader reporting and review workflows.
