"Shodan is a search engine that lets the user find specific types of computers (webcams,routers,servers, etc.) connected to the internet using a variety of filters. Some have also described it as a search engine of service banners, which are metadata that the server sends back to the client.This can be information about the server software, what options the service supports, a welcome message or anything else that the client can find out before interacting with the server." --WikipediaSo you get shodan a little bit right? Now, how are we going to search these on line devices (IOT) with the help of shodan? Just visit SHODAN.
Now you can submit your queries such as webcams, default password etc. If you are lucky you will get access to those devices without a password or with default password like admin.
