Introducing BeEF
BeEF is short for Browser Exploitation Framework. It is an open source penetration testing tool focused on exploiting vulnerabilities in the web browser.
As an open source project, BeEF relies on a community of developers to maintain and improve the project. If you're interested in contributing to the BeEF project, there is a whole section in the wiki dedicated to developer knowledge to help get you started! IV - Development
BeEF started in 2006 as a Ruby project, developed by a team led by Wade Alcorn. Amid growing concerns about web-borne attacks against both web and mobile clients, BeEF allows penetration testers to assess the security posture of a target environment by using client-side attack vectors. Unlike other security frameworks, BeEF looks past the hardened network perimeter and client system, and examines exploitability within the context of the one open door: the web browser. BeEF will hook one or more web browsers and use them to launch directed command modules and further attacks against the system from within the browser context.
