CNNMoney.com calls Shodan “the scariest search engine on the Internet.” Why? “Unlike Google, which crawls the Web looking for websites, Shodan navigates the Internet's back
channels,” it writes. “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.” Who uses such a service? Mostly penetration testers, security professionals, academic researchers and law enforcement agencies, thought cybercriminals are thought to frequent Shodan,
too.
