Dnscan is a python wordlist-based DNS subdomain scanner
A DNS meta-query spider that enumerates DNS records, and subdomains.
Fierce is a semi-lightweight scanner that helps locate non-contiguous IP space and hostnames against specified domains. It's really meant as a pre-cursor to nmap, unicornscan, nessus, nikto, etc, since all of those require that you already know what IP space you are looking for. This does not perform exploitation and does not scan the whole internet indiscriminately. It is meant specifically to locate likely targets both inside and outside a corporate network. Because it uses DNS primarily you will often find mis-configured networks that leak internal address space. That's especially useful in targeted malware.
$ pip3 install fierce
$ fierce -h
Anubis is a subdomain enumeration and information gathering tool. Anubis collates data from a variety of sources, including HackerTarget, DNSDumpster, x509 certs, VirusTotal, Google, Pkey, and NetCraft. Anubis also has a sister project, AnubisDB, which serves as a centralized repository of subdomains.
Prerequisites
If you are Linux user, the following modules or libraries are also required:
sudo apt-get install python3-pip python-dev libssl-dev libffi-dev
pip3 install anubis-netsec
snap install anubis
Nmap can Attempts to enumerate DNS hostnames by brute force guessing of common subdomains. With the dns-brute.srv argument, dns-brute will also try to enumerate common DNS SRV records. Wildcard records are listed as "*A" and "*AAAA" for IPv4 and IPv6 respectively.
The dns-brute module of nmap request the following.
coroutine dns io math rand Lepus is a utility for identifying and collecting subdomains for a given domain. Subdomain discovery is a crucial part during the reconnaissance phase. One of the strength of Lepus lies at Performing several checks on identified domains for potential subdomain-takeover vulnerabilities. The module is enabled with --takeover and is executed after all others. If such a vulnerability is identified, the results are printed in the output and in a .csv file in the respective project folder under the directory with the results. Checks are performed for the following services. Lepus performs the following. Services (Collecting subdomains from the below services) Dictionary mode for identifying domains (optional) Permutations on discovered subdomains (optional) Reverse DNS lookups on identified public IPs (optional)

It has a simple modular architecture and has been aimed as a successor to 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

SubDomainizer is a tool designed to find hidden subdomains and secrets present is either webpage, Github, and external javascripts present in the given URL. This tool also finds S3 buckets, cloudfront URL's and more from those JS files which could be interesting like S3 bucket is open to read/write, or subdomain takeover and similar case for cloudfront. It also scans inside given folder which contains your files.

SubScraper uses DNS brute force, Google & Bing scraping, and DNSdumpster to enumerate subdomains of a given host. Written in Python3, SubScraper performs HTTP(S) requests and DNS "A" record lookups during the enumeration process to validate discovered subdomains. This provides further information to help prioritize targets and aid in potential next steps. Post-Enumeration, "CNAME" lookups are displayed to identify subdomain takeover opportunities.

Horn3t is your Nr #1 tool for exploring subdomains visually. Building on the great Sublist3r framework (or extensible with your favorite one) it searches for subdomains and generates awesome picture previews. Get a fast overview of your target with http status codes, add custom found subdomains and directly access found urls with one click.

dnscan is a python wordlist-based DNS subdomain scanner. The script will first try to perform a zone transfer using each of the target domain's nameservers. If this fails, it will lookup TXT and MX records for the domain, and then perform a recursive subudomain scan using the supplied wordlist.

A Powerful Subdomain Scanner & Validator Written in sockets which makes it a lot more faster and easier to manage. It works by enumerating subdomains by searching them on web and by using local wordlists. It further identify the assets of a domain based on their ip and CNAME records and identify subdomains which are using the same IP addresses. It also scan ports if are given and enumerte possible server engines used on assets using the SERVER header returned in the response. It also enumerates possible returned HTTP status codes on port 80 and 443

Blackbird was designed to automate and handle the heavy lifting of recon for large domains. It currently uses the following tools to do the following functionalities. Blackbird also uses a slack legacy token to alert you whenever a certain segment from the functionalities listed above has been started or is finsihed. Finally you can also choose to run the BlackBird API, the API allows you to launch the scanner from slack or any other tool of choice!

Sublist3r is a python tool designed to enumerate subdomains of websites using OSINT. It helps penetration testers and bug hunters collect and gather subdomains for the domain they are targeting. Sublist3r enumerates subdomains using many search engines such as Google, Yahoo, Bing, Baidu, and Ask. Sublist3r also enumerates subdomains using Netcraft, Virustotal, ThreatCrowd, DNSdumpster, and ReverseDNS. subbrute was integrated with Sublist3r to increase the possibility of finding more subdomains using bruteforce with an improved wordlist. The credit goes to TheRook who is the author of subbrute
