As we are a man (or in this case a proxy) in the middle (MITM), the browser will think there is something wrong and will throw an error as seen above. Lots of sites have TLS (HTTPS) to encrypt the data from the client to their server. However, if we visit a HTTPS site such as: we will get a horrible TLS error: This is all traffic your browser is generating. You may also see lots of other request Burp picks up. If you navigate to a HTTP website such as Burp will pick it all up:īurp will hold the proxied request until you either stop intercepting or click the forward button. Hooorrraaaayyy, we now have Burp Suite intercepting any traffic we generate through the browser. Make sure your checkbox for running is ticked. You will find if you open Burp Suite, click Proxy and then option, there will be a proxy listener with these details: What you are doing now is proxying all of your web traffic through your local machine that is being intercepted by anything that is listening. To stop your browser from tunneling everything through to your machine first, open up your firefox network settings again and click 'No proxy'

On Firefox, open the preferences (about:preferences#general) and scroll to the bottom where you can see Network Settings then click on Settings.

Other browsers will work, just have to find the correct browser setting. Now we have Burp installed we need to get it to intercept our traffic. You should be presented with the following interface: One you have Burp installed open the application.

Configure the TLS (self-signed) certificate for HTTP S interceptingĭownload Burp from here (make sure you have Java installed too).

Configure the browser to intercept all our traffic for inspection.

For the purpose of this tutorial I will be using the free version. In this set of tutorials we will go through how to set up Burp to intercept traffic on your web browser. Burp Suite (referred to as Burp) is a graphical tool for testing web application security.
