Typical severity: Medium. Likelihood of attack: Low. An adversary registers a domain name with at least one character different than a trusted domain. A TypoSquatting attack takes advantage of instances where a user mistypes a URL (e.g. www.goggle.com) or not does visually verify a URL before clicking on it (e.g. phishing attack). As a result, the user is directed to an adversary-controlled destination. TypoSquatting does not require an attack against the trusted domain or complicated reverse engineering.
Authenticate all servers and perform redundant checks when using DNS hostnames. | Purchase potential TypoSquatted domains and forward to legitimate domain.
