What is BeEF – The Browser Exploitation Framework

What is BeEF?

BeEF is short for The Browser Exploitation Framework. It is a web-based login testing tool.

Amid growing concerns about web-based attacks on customers, including mobile clients, BeEF allows a professional login inspector to check the actual location of the targeted security environment using client-side attack vectors. Unlike other security frameworks, BeEF looks beyond the rigid network perimeter and client system, and tests usage within the context of one open door: a web browser. BeEF will connect to one or more web browsers and use them as marine heads to launch targeted command modules and additional attacks against the system within the browser context.

Browser Exploitation Framework (BeEF) is a penetration test, or pen scanner, a tool designed to provide attack vectors on the active client side and exploit any potential threats in a web browser. BeEF differs between pen testing frameworks because it does not attempt to address the most secure network features of the system. Instead, BeEF adheres to one or more web browsers to be used as a Paid for Injectable Payment, to exploit exploit modules, and to evaluate the risk program by adhering to browser-influenced services.
BeEF has a very competent, but straightforward API, which acts as a pivot where its efficiency stops and grows up to mimic a full cyber attack.

This short tutorial will look at a few ways this flexible and flexible tool can be used to test pen.

Browser Exploitation Framework (BeEF) is a powerful and intelligent defense tool. BeEF is the first strategy that provides entry testers with effective vectors of attack on the client side. Unlike other security frameworks, BeEF focuses on using browser vulnerabilities to assess the security status of the target. This project is for formal research purposes only and access checks.

BeEF connects one or more web browsers to the application submission of targeted command modules. Each browser may be in a different defensive context, and each context may provide a different set of attack vectors. The framework allows the login checker to select specific modules (in real time) to guide each browser, hence each context.

The framework contains many command modules that use a simple and powerful BeEF API. This API is at the heart of the efficiency and effectiveness of the framework. It summarizes the complexity and facilitates the rapid development of custom modules.


Install BeEF

BeEF is built specifically for Kali Linux 2019.2 and above, so you do not have to install anything when using one of those versions on your computer.

In mid-2019, Kali removed BeEF as a pre-installed exploit tool, moving it from “kali-linux-default” to “kali-linux-large” metapackage. That means that once you install the new version of Kali, you will no longer have BeEF, however, you can save it if you update your old version of Kali to 2019.3 or higher.

Once you have it, use the following command to review everything. And if you don’t, the same command will apply. Just make sure you use beef-xss and not “beef” because the latter is a translator of the programming language, which is different. (We made that mistake in our video above, so do not do the same.)

$ sudo apt install beef-xss

Whether you have installed it before or should have installed it, everything is the same.


Open BeEF Service

Once the BeEF is installed, you can find it under Applications -> System Services, and click on “Start Cow”. It will open a terminal window to start the service.

If you do not see any beef related tools in that folder, or if you do not see that folder at all, you may have installed “beef” and not “beef-xss” so be sure to do the latest. (You can also start the BeEF in the exploitation tools folder when “in the cow xss framework.)

If you have errors when your browser fails to load, you can bypass the problem by opening your favorite web browser, such as Firefox or Chrome, and go to the following URL, localhost ( web server in port 3000.
