Domain name permutation engine written in Go

DNSMORPH is a domain name permutation engine, inspired by dnstwist. It is written in Go making for a compact and very fast tool. It robustly handles any domain or subdomain supplied and provides a number of configuration options to tune permutation runs.

DNSMORPH includes the following domain permutation attack types:

• Homograph attack (both on single and duplicate characters)
• Bitsquat attack
• Hyphenation attack
• Omission attack
• Repetition attack
• Replacement attack
• Subdomain attack
• Transposition attack
• Vowel swap attack
• Addition attack

Installation

There are two ways to install dnsmorph on your system:

1. Downloading the pre-compiled binaries for your platform from the latest release page and extracting in a directory of your choosing.

2. Downloading and compiling the source code yourself by running the following commands:

   • go get -v github.com/netevert/dnsmorph
   • cd /$GOPATH/src/github.com/netevert/dnsmorph
   • go get -v ./...
   • go build

An Arch Linux package is also available.
