SubDoxer

Overview

SubDoxer is a Python tool designed to discover subdomains associated with a target domain. Ideal for cybersecurity enthusiasts and penetration testers, this tool helps you map out potential subdomains quickly and efficiently.

Version 1.1 of SubDoxer utilizes a predefined list of over 500 common and potential subdomains to check against a target domain. It employs DNS resolution to verify the existence of these subdomains.

Features

  • DNS Resolution: Uses DNS 'A' record checks to verify subdomain existence.
  • Multithreading: Accelerates the process using concurrent threads.
  • Extensive Subdomain List: Includes over 500 predefined subdomains.
  • Customizable: Easily extendable with additional subdomains.
  • Colorful Output: Provides clear and colorful console output using colorama.
