Shodan is a new search engine like Google but specialized in one job. It can be used to find out unprotected servers, the ones with default passwords like “1234” or “pass” or whatever. It can be used to search for webcams, netcams, SCADA systems and much more! It is there for about 3 years now but not very popular with common people. It is however very popular with hackers who try to find out unprotected systems potentially vulnerable for hacking.
Shodan provides a very clean interface and one can expect good results on very simple search keywords like “default password”. It is sometimes eulogized with terms like “Google for Hackers”. It is crawling the web 24/7 and uses special methods to find its targets. Even amateur users can easily find out unprotected shop and office security cameras and see people moving about and ignorant about the fact that they are being watched on the internet.
Keeping its dark aspects aside, the site does not allow arbitrary searching by any visitor. To access search pages after the first one a user has to log in to Shodan. Registering there is totally free and they take no charges whatsoever for any search operations you do there.
If Shodan could also incorporate “generic” search capabilities like Google it well could become the top search engine. Now that we know about Shodan we should not think our domains are invisible if not not visible on Google search. Shodan is watching you!
