Burp Suite Proxy Intercept

Introduction

This tutorial covers the proxy intercept feature of Burp Suite, a widely used tool in penetration testing and ethical hacking. By learning how to configure and utilize this feature, you can effectively gather valuable information during your security assessments.

Step 1: Setting Up Burp Suite

• Download and Install Burp Suite

  • Go to the official Burp Suite website.
  • Download the appropriate version for your operating system.
  • Follow the installation instructions provided.

• Launch Burp Suite

  • Open the application after installation.
  • Choose the "Temporary Project" option for quick testing or create a new project if you intend to save settings.

Step 2: Configuring the Proxy Settings

• Access Proxy Settings

  • In the Burp Suite interface, navigate to the "Proxy" tab.
  • Select the "Options" sub-tab.

• Set Up the Proxy Listener

  • By default, Burp Suite listens on 127.0.0.1:8080. Ensure this setting is correct.
  • If needed, you can modify the port number to fit your network setup.

• Configure Browser to Use Burp Proxy

  • Open your web browser and access the network settings.
  • Set the proxy configuration to manual.
  • Enter the Burp Suite proxy settings:
    • Address: 127.0.0.1
    • Port: 8080

Step 3: Enabling Intercept

• Activate Intercept Feature

  • In the "Proxy" tab, switch to the "Intercept" sub-tab.
  • Ensure that intercept is turned on by clicking the "Intercept is on" button, which will change to "Intercept is off".

• Interception of HTTP Requests

  • With intercept enabled, any HTTP request made by the browser will be caught by Burp Suite.
  • You can review and modify requests before they reach the target server.

Step 4: Analyzing and Modifying Requests

• View and Edit Requests

  • When a request is intercepted, it will appear in the Burp Suite interface.
  • You can modify headers, parameters, or body content as needed.

• Forwarding Requests

  • Once you finish analyzing or modifying a request, click the "Forward" button to send it to the server.
  • Use the "Drop" button to discard unwanted requests.

Step 5: Using HTTP History

• Access HTTP History

  • After requests are sent, navigate to the "HTTP history" sub-tab under the "Proxy" tab.
  • Here, you can view all requests and responses that have been processed.

• Analyzing Responses

  • Click on individual entries to review the response data.
  • This information can help identify vulnerabilities or gather insights about the target application.

Conclusion

In this tutorial, you learned how to set up and use the proxy intercept feature in Burp Suite. By configuring the proxy, enabling intercept, and analyzing requests and responses, you can perform effective information gathering during penetration tests. Next steps could include exploring additional features of Burp Suite, such as intruder and scanner tools, to further enhance your testing capabilities.
