Happy birthday Nmap!

[Pierre LALET <pierre () droids-corp org>]

Hi Nmap,

I understand you've just turned 18. Happy birthday! You can now drink
alcohol (OK, not everywhere) and watch porn (OK, probably not
everywhere)!

I have a present for you, a script to grab screenshots from Web
servers. It does not qualify for inclusion in your source tree, since
it relies on external programs, but I though it might interest some
people here.

It is similar to the script from SpiderLabs [1] but relies on a
PhantomJS script rather than Wkhtmltoimage.

[1] https://github.com/SpiderLabs/Nmap-Tools/blob/master/NSE/http-screenshot.nse

It is integrated to an opensource network recon project (IVRE, which
is French for DRUNK, have a look now you're allowed!), but it can be
used alone:

  - install PhantomJS

  - get the PhantomJS script [2], make it executable and install it to
    a directory in your PATH

  - get the NSE script [3], install it to Nmap's script directory, run
    'nmap --script-update'

[2] https://github.com/cea-sec/ivre/raw/master/docker/client/screenshot.js

[3] https://github.com/cea-sec/ivre/raw/master/docker/client/http-screenshot.nse

If you're too lazy, you can get the Docker image ivre/client and run
Nmap from a container.

Now you are old enough, you can see that:


$ nmap -p 80 --script=http-screenshot www.youporn.com

Starting Nmap 6.49SVN ( https://nmap.org ) at 2015-09-02 11:26 CEST
Nmap scan report for www.youporn.com (31.192.116.24)
Host is up (0.016s latency).
PORT   STATE SERVICE
80/tcp open  http
|_http-screenshot: Saved to screenshot-31.192.116.24-80.jpg


OK let's see if it worked:


$ convert screenshot-31.192.116.24-80.jpg -crop 193x40+7+35 \

Cheers!
