Hacker's paradise is the search engine Shodan that crawls and finds online devices. This scary search engine allows users to expose internet-connected devices such as iPhones, routers, baby monitors, office building heating-control systems, webcams, medical devices, traffic lights, cars and even the power plant controls with much more.
Shodan is a search engine that has totally different crawling methods than Google. Google crawls online websites while Shodan crawls online devices like his founder said. A 29-year-old young guy named John Matherly build Shodan in 2009.
This search engine basically allows users to expose and also hack online devices using the security flaws in these internet-connected devices. Matherly named Shodan after "the villainous sentient computer in the videogame System Shock," according to Forbes. He said, “It’s a reference other hackers and nerds will understand.”
Matherly actually has not invented Shodan for hackers. He builds this search engine to be used by network giants like Microsoft, Ciscoc and others 'to canvas the world for their competitors’ products.' But this search engine has now become an important tool for police, security researchers and academics that want to expose such devices that should not be o the internet. Hackers also use is widely to hack such devices that have security flaws.
But if we look at expected figures of internet-connected devices, that a Swedish tech company Ericsson estimates to be 50 billion by 2020, Shodan is a big threat for all. Yet Matherly do not admit that his search engine is scary or any threat. He says, “I don’t consider my search engine scary. It’s scary that there are power plants connected to the Internet.”
