How to Setup Sublist3r – Fast Subdomains Enumeration Tool

 Hi friends, today we're going to talk about a really easy-to-use yet effective tool for gathering the site's subdomains. I'll walk you through setting up Sublist3r, a quick tool for enumerating subdomains.

About Sublist3r

A Python tool called Sublist3r is intended to list website subdomains by utilizing multiple OSINT sources. It facilitates the collection and gathering of subdomains for the target domain by penetration testers and bug hunters. Many search engines, including Google, Yahoo, Bing, Baidu, and Ask, are currently supported by Sublist3r. In the future, more search engines might be added. Additionally, Sublist3r uses DNSdumpster, Virustotal, ThreatCrowd, Netcraft, and PassiveDNS to compile subdomains.

Sublist3r and subbrute were combined to boost the likelihood of employing bruteforce and a better wordlist to discover more subdomains. TheRook, the creator of subbrute, deserves all the recognition.
