Shodan is an all new search engine. Unlike its contemporaries it doesn't crawl only the visible web. The visible web or the surface web is the part which search engine bots crawl and index. But Shodan search engine has access to peripherals, machines and several components of the Darknet. Shodan search engine : Knight of the Dark Web. Shodan search engine can even allow its users access to traffic signals or nuclear power plants! There was a similar A.I module in the PC game System Shock 2 named Shodan which made gamers run for their lives. So, taking hint from that John Matherly, a computer engineer has created the Shodan search engine. It can find a large number of devices connected to the internet. Anyone with an internet connection can access those devices which show up as unprotected on the Shodan results. "When people don't see stuff on Google, they think no one can find it. That's not true. - John Matherly" Shodan has information on 500 million devices which are connected to the internet! The kind of security failures discovered with Shodan are so wide scale that anything and everything that is connected to the Internet can be targeted if it's not running proper security measures!

A little example to demonstrate it's power can be one by Dan Tentler, who showcased how Shodan could be used to find control systems for garage doors, pressurized water heaters and coolers working on evaporation. "He in his endeavours found out that a whole car wash could be turned ON/OFF. An ice hockey rink in Denmark that he could melt with a single click. A city's entire traffic module was connected to the Internet and with one command entry it could be put to "TEST MODE". Also in his findings was the control system for a Hydroelectric power plant in France which had 2 turbines with capacity of 3 MW each! " And that's some serious power! And the reason that such things aren't secure in the first place is that security is thought later. The engineers and designers believe such devices to be hard to find. But now with the Shodan search engine it doesn't seem so. The conclusion is that right now Shodan is exclusively used for good purposes. Like finding worldwide security holes and patching them etc. Matherly had already completed Shodan 3 years ago. Screenshot of Homepage of Shodan.
