subblaster

Super-fast multi-source subdomain bruteforcer in Go.

Note: This is not a public subdomain enumerator and is not an efficient way to get pre-captured subdomains. If you need fast enumeration, please use pre-existing tools like amass, sublister etc.

What is this then?

There are several domains whose subdomains are present in DNS records but aren't caught by popular enumeration services. These don't appear online due to them not being scraped by crawlers that these providers / security companies deploy. This tool is an attempt to maximize the speed of discovering them while minimizing the time taken.

Features

Customizable multi-source wordlists (TheRook's subbrute, Daniel Miessler's seclists and more!)
Multithreaded bruteforcing using Golang
Multi-resolver subdomain resolution and port scanning in-built
Multiple inputs, multiple outputs

Usage

# to build the program
go build

./subblaster 0x4f.in

Examples:

Generate paired JSON outputs

This helps generate output in the form of {"subdomain": "www.example.com", "domain":"example.com"}, useful for dumping to a DocumentDB
