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.

How Does it Work?

XRay is a very simple tool, it works this way:

1. It’ll bruteforce subdomains using a wordlist and DNS requests.
2. For every subdomain/ip found, it’ll use Shodan to gather open ports and other intel.
3. For every unique ip address, and for every open port, it’ll launch specific banner grabbers and info collectors.
4. 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.
• HTML title tag.
• DNS version.bind. and hostname.bind. records.
• MySQL, SMTP, FTP, SSH, POP and IRC banners.

Notes

Shodan API Key

The shodan.io API key parameter ( -shodan-key KEY ) is optional, however if not specified, no service fingerprinting will be performed and a lot less information will be shown (basically it just gonna be DNS subdomain enumeration).

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 behavior.

Installation

Make sure you are using Go >= 1.7, that your installation is working properly, that you have set the $GOPATH variable and you have appended $GOPATH/bin to your $PATH.

Then:

go get github.com/evilsocket/xray
cd $GOPATH/src/github.com/evilsocket/xray/
make get_glide
make install_dependencies
make build

If you see errors regarding a missing go-bindata binary, try the following and then make build again:

go get -u github.com/jteeuwen/go-bindata/...

You’ll find the executable in the build folder.

Usage

Usage: xray -shodan-key YOUR_SHODAN_API_KEY -domain TARGET_DOMAIN
Options:
  -address string
        IP address to bind the web ui server to. (default "127.0.0.1")
  -consumers int
        Number of concurrent consumers to use for subdomain enumeration. (default 16)
  -domain string
        Base domain to start enumeration from.
  -port int
        TCP port to bind the web ui server to. (default 8080)
  -session string
        Session file name. (default "<domain-name>-xray-session.json")
  -shodan-key string
        Shodan API key.
  -wordlist string
        Wordlist file to use for enumeration. (default "wordlists/default.lst")

Example:
