Querying Shodan to obtain target information

Shodan is a search engine for Internet-connected devices. It is a useful source of information where we can find port and banner information of remote targets. One of the advantages is that we don't even need to send a single packet directly to the target to obtain juicy host information, including port number, protocol, and service banner.

In this recipe, you will learn how to use Shodan to obtain port and version information from a remote host with Nmap.

Getting ready

The NSE script shodan-api needs an API key before it can be used. Shodan offers a free developer API that you can obtain from 

https://developer.shodan.io/.

Make sure that you have your Shodan API key at hand before continuing.
