Last month a new search engine appeared, called Shodan. It is a Computer Search Engine, available for free in public, allowing search for routers, servers, computers or any device that opens a port. It is based on a simple idea: Port scan, grab headers and index the results. Quoting Shodan’s quick guide, “SHODAN lets you find servers/ routers/ etc. by using the simple search bar up above. Most of the data in the index covers web servers at the moment, but there is some data on FTP, Telnet and SSH services as well. Let me know which services interest you the most and I’ll prioritize them in my scanning”.
