Shodan is commonly known for allowing users to search for banners displayed by a short list of services available over the internet. Shodan can quite easily be used for searching the internet for potentially vulnerable services to exploit, but its also a powerful defensive posturing tool as well as the first step in aggregating wide scopes of data for mining. Everyone knows routers, switches and servers are connected to the internet but what else is out there? Has anybody even looked? I suspect people stop after the popular searches and forego whats left. Did you know there are hydrogen fuel cells attached to the internet? Some of my findings were pretty surprising, and these discoveries are an excellent metric for identifying how successful our security campaigns as an industry are. Its a way to measure our success as a whole, by scanning the entire internet.
