Shodan is an Internet search engine capable of finding just about every connected thing imaginable.
"When people don't see stuff on Google, they think no one can find it. That's not true." That's according to John Matherly, creator of Shodan, the scariest search engine on the Internet.
Unlike Google, which crawls the Web looking for websites, Shodan navigates the Internet's back channels. It's a kind of "dark" Google, looking for the servers, webcams, printers, routers and all the other stuff that is connected to and makes up the Internet.
