FOFA

FOFA (fofa.info) is a Chinese cyberspace search engine that indexes internet-facing hosts, services, and devices by banner, header, certificate, and icon fingerprints, letting researchers query for exposed assets much like Shodan or Censys. It supports a custom query syntax, icon/favicon-hash search, batch search, and an API for programmatic recon, making it a common tool for attack-surface discovery, threat hunting, and OSINT investigations.
