Enumerate available domains generated modifying the original domain name through different cybersquatting techniques
About Squatm3gator
Squatm3gator is an open source web application built on the squatm3 Python tool. It generates domain names by modifying an original domain through several cybersquatting techniques, then enumerates which of the generated domains are available. The techniques include substitution, flipping, and two homoglyph modes: a fast mode that changes one letter at a time, and a complete mode that generates all possible combinations.
The project is intended for penetration testers who need lookalike domains for phishing attack simulations, and for security analysts who want to detect and prevent cybersquatting. The source describes running it with Docker Compose, after which the application is available at localhost:5000. The project is licensed under the GNU GPL and is at version 1.5. It has been presented at Black Hat Arsenal Europe 2018 and Black Hat Arsenal Asia 2019.
