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
Generates permutations, alterations and mutations of subdomains and then resolves them
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
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。
