I had a lot of fun making this and I hope this project will change the way you see subdomain enumeration. The method explored here is highly effective and efficient.

This software is a subdomain enumeration tool.

A tool to bruteforce dumains!

Knock is an attack surface management tool and DNS reconnaissance framework used for discovering and mapping an organization's external infrastructure. It functions as a subdomain enumeration tool and HTTP security scanner to identify reachable hosts and organizational assets. The project distinguishes itself by using a passive-active hybrid enumeration strategy, combining external API lookups with active wordlist brute-force attacks and DNS zone transfers. It includes a multi-stage validation pipeline that detects DNS wildcard records and verifies host connectivity to filter out false positi

Subfinder is a passive subdomain enumeration tool and DNS discovery utility designed to identify valid subdomains and hostnames associated with a specific organization or domain. It functions as a passive reconnaissance tool, gathering information about target domains by querying online databases without sending network traffic to the target infrastructure. The tool utilizes a pluggable provider architecture to separate discovery logic into independent modules, allowing for the integration of multiple passive-source APIs. It employs a concurrent-worker request model to execute network request

Subdomain enumeration tool

ksubdomain是一款基于无状态子域名爆破工具，支持在Windows/Linux/Mac上使用，它会很快的进行DNS爆破，在Mac和Windows上理论最大发包速度在30w/s,linux上为160w/s的速度。 ksubdomain的发送和接收是分离且不依赖系统，即使高并发发包，也不会占用系统描述符让系统网络阻塞。

theHarvester is a command-line utility designed for gathering open-source intelligence and mapping an organization's external attack surface. It functions as a security information gathering framework that automates the collection of publicly available data to assist in reconnaissance and threat analysis. The tool utilizes a plugin-based architecture to execute isolated queries against various search engines and public databases. It employs asynchronous task execution to run multiple discovery operations in parallel, while a centralized pipeline aggregates and deduplicates findings from these

A fast sub domain brute tool for pentesters

Aquatone is a web screenshot reconnaissance tool that captures full-page screenshots of web services discovered during network reconnaissance and groups them by visual similarity. It scans a list of hosts or domains for HTTP and HTTPS services on common and custom ports to find responsive web endpoints, then takes full-page screenshots of those pages for quick review. The tool accepts piped input from other tools and extracts URLs, domains, and IP addresses using regex pattern matching, making it pipeline-friendly for integration into existing workflows. It can also read XML output from Nmap

Listing subdomains about a main domain using the technique called Hacking with search engines.

Amass is a network attack surface mapper and reconnaissance framework designed to discover and map the external, internet-facing infrastructure of a target organization. It functions as an open source intelligence tool that identifies public network boundaries and locates hidden or forgotten subdomains to define an organization's total reachable footprint. The project utilizes passive-source data aggregation from external APIs and public databases alongside active DNS brute-forcing and recursive subdomain expansion. It employs a graph-based asset mapping system to visualize the relationships

Sublist3r is a subdomain enumeration tool and passive reconnaissance framework designed to discover subdomains by querying search engines and public intelligence sources. It functions as a security tool for identifying the digital footprint of a target domain. The project provides both passive enumeration through multi-source API aggregation and active discovery via a DNS brute force tool. It includes a TCP port scanner to identify active services and open ports on discovered subdomains, facilitating attack surface mapping. The tool can be used as a standalone utility or as a Python security
