What is Subfinder ❓
For the exploration and detection of subdomains, Subfinder is a tool that is publicly available. This open-source software is ideal for those involved in cybersecurity research, as well as those participating in bug bounty initiatives and penetration testing.
Subdomains are subsidiary domains that are attached to a primary domain entity. For instance, with “example.com” as the primary domain, “subdomain.example.com” would be one of its subdomains.
How Subfinder Works 🤔
Using a combination of search engines, certificate transparency logs, and DNS databases, Subfinder conducts searches to uncover subdomains associated with a targeted domain.
Its approach to subdomain enumeration employs both passive and active techniques.

Example 2, Scanning from List
To scan a bunch of targets from a file you can add the below command.

We can also set the threads upto 10, But I recommend you to go with 4 for better results.

In my personal opinion this is an another sub domain enum tool like sublist3r, I personally prefer to use sublis3r. I appreciate all the contributors ❤️
