The Browser Exploit Framework (BeEF) is an easy-to-use open-source tool for attacking web browsers used by security professionals and attackers alike. There are few known methods for defending against BeEF attacks, so I decided to build a Chrome extension to thwart attacks. It is called Vegan.
The Vegan Chrome Extension can be downloaded here. This is an open source proof of concept, and is provided as is. Use at your own discretion.
