XRay: a great network OSINT gathering tool

Really useful in the first phases of a penetration test


XRay is a tool for network OSINT gathering developed by Simone Margaritelli, useful to make initial tasks of information gathering and network mapping.

It make a bruteforce of subdomains using a wordlist and DNS requests, and for every subdomain/ip found retrieves from Shodan the open ports and from ViewDNS some historical data.
Finally, for every unique ip address, and for every open port, it launch specific banner grabbers and info collectors.

Grabbers and Collectors

  • HTTP Server, X-Powered-By and Location headers.
  • HTTP and HTTPS robots.txt disallowed entries.
  • HTTPS certificates chain.
  • HTML title tag.
  • DNS version.bind. and hostname.bind. records.
  • MySQL, SMTP, FTP, SSH, POP and IRC banners.

Anonymity and Legal Issues

The software will rely on your main DNS resolver in order to enumerate subdomains, also, several connections might be directly established from your host to the computers of the network you’re scanning in order to grab banners from open ports. Technically, you’re just connecting to public addresses with open ports (and there’s no port scanning involved, as such information is grabbed indirectly using Shodan API), but you know, someone might not like such behaviour.

If I were you, I’d find a way to proxify the whole process … #justsaying
