SubBrute

A DNS meta-query spider that enumerates DNS records, and subdomains.

DNS reconnaissance using Fierce

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.

Installing Fierce

$ pip3 install fierce

$ fierce -h

Features of Fierce
  • Traverse IPs near discovered domains
  • Attempt an HTTP connection on domains discovered
  • Zone transfers
Anubis information gathering tool

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.

How to install Installing

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

Features of Anubis subdomain enumeration
  • AnubisDB
  • Advanced features like using nmap
  • Uses Shodan
Subdomain scanning using Nmap dns-brute

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 requires the following.

  • coroutine coroutine
  • dns dns
  • io io
  • math math
  • rand rand

Tools developed for subdomain finding

  • SubFinder

    SubFinder is a subdomain discovery tool that discovers valid subdomains for websites by using passive online sources. 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

    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

    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

    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

    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
