Subdomain Scanner

A wordlist based subdomain scanner written in golang. It scans a target domain for subdomains using a provided wordlist and saves the discovered subdomains with a status code of 200 to an output file.

Usage

Prerequisites

• Install Go

Running the Scanner

1. Clone or download the repository.

2. Open a terminal and navigate to the directory containing scanner.go.

3. Run the following command:

   go run scanner.go -domain example.com

   Replace example.com with the target domain you want to scan.

Options

• -domain: Specify the target domain to scan (required).

• -wordlist: Path to the wordlist file containing subdomains. Defaults to subdomains.txt.

• -output-file: Output file to write found subdomains. Defaults to found-subdomains.txt.

Example

go run scanner.go -domain example.com -wordlist custom-wordlist.txt -output-file discovered-domains.txt

This command will scan example.com using a custom wordlist (custom-wordlist.txt) and save the discovered subdomains to discovered-domains.txt.

Note

• The program will only write subdomains with a status code of 200 to the output file.

• Ensure that you have the necessary permissions to scan the target domain.

• Use responsibly and respect the terms of service of the target domain.
