SHODAN is a computer search engine. But is is unlike any other search engine. While other search engines scour the web for content, SHODAN scans for information about the sites themselves. The result is a search engine that aggregates banners from well-known services. For penetration testers, SHODAN is a game-changer, and a goldmine of potential vulnerabilities.
