Hi all,

Here's a nse script to do passive scanning, querying the Shodan API:
  https://github.com/glennzw/shodan-hq-nse

Example usage:

Tweet to RT/whatever if you're into such things:

Hi,

Nice!

I'm not exactly an NSE pro, but I'm getting the impression that instead
of having to remember to specify -Pn -sn, perhaps it would be better to
also be able to specify the IP via --script-args so that Nmap doesn't
know about the IP at all. Right now we're not completely stealthy -
there's also the rDNS lookup performed.

I'm seeing a lot of potential for this kind of scripts - they could for
example diff against the already performed scan. If I was you though,
I'd first make sure that this is something that Nmap maintainers are
willing to include in the official distribution - I personally don't
know the line between acceptable and inacceptable external scripts.

Cheers,
d33ath
