SubFinder is a subdomain discovery tool that uses various techniques to discover massive amounts of subdomains for any target. It has been aimed as a successor to the sublist3r project. SubFinder uses Passive Sources, Search Engines, Pastebins, Internet Archives, etc to find subdomains and then it uses a permutation module inspired by altdns to generate permutations and resolve them quickly using a powerful bruteforcing engine. It can also perform plain bruteforce if needed. The tool is highly customizable, and the code is built with a modular approach in mind making it easy to add functionalities and remove errors.
- Simple and modular code base making it easy to contribute.
- Fast And Powerful Bruteforcing Module
- Powerful Permutation generation engine. (In Development)
- Many Passive Data Sources (29 At Present)
- Multiple Output formats
