5 Powerful Linux Tools to Discover Subdomains as an Ethical Hacker

If you're an ethical hacker, gathering information about the subdomains of a website is important. Here are some free Linux tools that will help you.

When it comes to web penetration testing, an essential aspect of the reconnaissance stage is the discovery of subdomains. Before diving into the actual pentesting, it's crucial to enumerate subdomains to gain a better understanding of the project's scope.

You never know what interesting domains you might stumble upon that could uncover significant vulnerabilities. Here we'll explore some fantastic free Linux tools that can assist you in this subdomain enumeration process. So let's dive in and discover these resources that can enhance your web security assessment capabilities.

A subdomain serves as an extension to the main domain of a website, offering a way to organize or differentiate various sections of the site. In a website's domain structure, there are two primary parts: the top-level domain (TLD) and the second-level domain (SLD).

In this case, the TLD is "com," while the SLD is "makeuseof." Now, if there was a dedicated section for partnerships on the site, the subdomain for this section could be named partnerships, resulting in the full URL partnerships.makeuseof.com. This subdomain allows for easy categorization and navigation within the website.
