XRay is a tool for network OSINT gathering, its goal is to make
some of the initial tasks of information gathering and network
mapping automatic.

XRay is a very simple tool, it works this way:
* It'll bruteforce subdomains using a wordlist and DNS requests.
* For every subdomain/ip found, it'll use Shodan to gather open
ports and other intel.
* If a ViewDNS API key is provided, for every subdomain
historical data will be collected.
* For every unique ip address, and for every open port, it'll
launch specific banner grabbers and info collectors.
* Eventually the data is presented to the user on the web ui.

Grabbers and Collectors
* HTTP Server, X-Powered-By and Location headers.
* HTTP and HTTPS robots.txt disallowed entries.
* HTTPS certificates chain ( with recursive subdomain grabbing
from CN and Alt Names ).
* HTML title tag.
* DNS version.bind. and hostname.bind. records.
* MySQL, SMTP, FTP, SSH, POP and IRC banners.
