subfinder
Discover subdomains of a target domain using passive and active enumeration techniques. Use when tasks involve subdomain enumeration, attack surface mapping, DNS reconnaissance, finding hidden services, identifying forgotten subdomains, or expanding the scope of a security assessment. Subfinder uses passive sources (certificate transparency logs, DNS datasets, search engines) to find subdomains without touching the target directly.
