Denum

Overview

Denum is a specialized tool for the reconnaissance phase of penetration testing and is particularly valuable for bug bounty hunters. It streamlines the process of gathering and cleaning domain names from URLs, enabling users to efficiently extract and standardize core domain names and subdomains. By doing so, Denum helps extend the scope of security assessments and vulnerability research, making it an essential asset for comprehensive and effective security investigations.

✨ Features

• Clean Domain Names: Converts URLs like https://www.example.com/ to example.com.
• Handle Various URL Formats: Supports different URL structures and protocols.
• Error Handling: Alerts if the input file is missing or if an invalid domain is encountered.

📚 Requirements

• Bash Shell
• jq (for JSON processing)
• curl (for HTTP requests)
• grep, awk, sed (for text processing)

🚀 Getting Started

1. Clone the repository:

   sudo apt-get update && sudo apt-get upgrade -y
   git clone https://github.com/kalmux1/Denum.git
   cd Denum
   sudo chmod +x denum.sh

2. Run the script:

   ./denum.sh -i input.txt -o output.txt

   • -i <file>: Specify the input file containing domain names.
   • -o <file>: Specify the output file to save cleaned domain names.

🛠️ How It Works

The script processes each line from the input file to extract and clean domain names. It uses a series of Bash commands to strip out unwanted URL components and then saves the cleaned domains to the specified output file.

• clean_domain(): Function to clean and standardize domain names from URLs.
• Error Handling: Alerts the user if there are issues with input files or invalid data.
