Cybertroopers storming your ship?

FindDomains is a multithreaded search engine discovery tool that will be very useful for penetration testers dealing with discovering domain names/web sites/virtual hosts which are located on too many IP addresses. Provides a console interface so you can easily integrate this tool to your pentest automation system.

It retrieves domain names/web sites which are located on specified ip address/hostname.

In order to use FindDomains you need to:

  1. Create an appid from “Bing Developers” at this link.
  2. It’ll be like that : 32AFB589D1C8B4FEC73D4BCB6EA0AD810E0FA2C7
  3. When you have registered an appid, enter it to the “appid.txt” which is in the program directory.


  • Uses Bing search engine. Works with first 1000 records.
  • Multithreaded on crawling and DNS resolution.
  • Performs DNS resolution for extracted domains to eleminate cached/old records.
  • Has a console interface so it can be very useful with some command-line foo.

    Entering IP: directly into Bing’s search engine achieves the same thing.
