http://www.readability.com/articles/bhvqeaukShodan runs 24/7 and collects information on about 500 million connected devices and services each month.
It's stunning what can be found with a simple search on Shodan. Countless traffic lights, security cameras, home automation devices and heating systems are connected to the Internet and easy to spot.
Shodan searchers have found control systems for a water park, a gas station, a hotel wine cooler and a crematorium. Cybersecurity researchers have even located command and control systems for nuclear power plants and a particle-accelerating cyclotron by using Shodan.
I am surprised this is the first time I am hearing about this!
A search for Gurgaon was not very interesting but I am sure there is enough data here to cause mayhem.
