Browser Exploitation Framework (BeEF) is a penetration testing tool designed to assess security posture through client-side attack vectors targeting web browsers. The framework operates by hooking one or more web browsers, establishing them as entry points for launching directed command modules and conducting further attacks against target systems from within the browser context. BeEF enables security professionals to evaluate the actual security posture of target environments by exploiting browser-based vulnerabilities and weaknesses. The tool provides a platform for executing various client-side attacks and assessing how browsers can be leveraged as attack vectors in penetration testing scenarios. The framework focuses specifically on browser-based exploitation techniques, allowing testers to understand and demonstrate the risks associated with client-side security vulnerabilities in web browser environments.
