Do you have a webcam? Have you put a password on it? You probably should, if you don’t fancy ending up on this creepy search engine.

Shodan is the world's first search engine for Internet-connected devices.

Shodan claims to be the world’s first search engine for internet-connected devices. It allows users to see which of their devices are connected to the Internet, see where it’s located, and who is using it. Since its creation in 2009, the site quickly exposed the how vulnerable a number of so-called Internet of Things devices were to hacking.
