1. Introduction

Burp Suite is an industry-renowned tool in the arsenal of cybersecurity professionals. The tool’s array of features makes it the de facto choice for web application security testing. In this post, we dive deep into the advanced techniques of Burp Suite, tailored for those who have a basic grasp of the tool and aim to elevate their skills to an expert level.

2. Setting Up and Configuring Burp Suite for Advanced Scanning

Before diving into advanced methodologies, ensuring Burp Suite is optimally configured is crucial.

• Optimized Memory Usage: Allocate more memory to Burp Suite if you plan to use it for extensive testing. In the 'VM options' section during the launch, set the maximum memory according to the available RAM.
• Up-to-date CA Certificates: Ensure that the Burp Suite CA certificate is installed on the browser/tested device. This allows seamless traffic interception without SSL/TLS warnings.
• Exclusions and Filters: Setting up appropriate scope and filters prevents scanning of out-of-scope areas, thereby conserving resources and time.

3. Mastering Extensions: Turbocharge Your Testing

Burp Suite's extensibility is one of its most potent features. Extensions can extend the capabilities of Burp Suite beyond its core functions.

• CO2: This extension provides multiple modules, including password profiling and various payload utilities.
• J2EEScan: Perfect for Java applications. It detects vulnerabilities specific to J2EE applications.
• Retire.js: Identifies JavaScript libraries with known vulnerabilities.

To install an extension, navigate to 'Extender' > 'BApp Store'. After installation, remember to configure the extensions as per the testing requirements.

4. In-depth Traffic Analysis: Beyond the Basics

With Burp Suite's Proxy tool, you can inspect, intercept, and modify the HTTP/HTTPS traffic.

• Highlighting: Use the 'highlight' feature in the HTTP history tab. This allows for easy identification of certain requests based on parameters or responses.
• Manual Mapping: As you browse the target application, requests and responses are recorded, enabling you to map the application manually.
• Response Rendering: The 'Render' tab provides a rendered view of the response, allowing you to see the application’s behavior.

5. Leveraging Automation with Burp Intruder

Intruder is a powerful component for automating custom attacks against applications.

• Sniper Mode: Useful for attacking single insertion points. The payload set can be customized to fit the requirement.
• Cluster Bomb: This mode is used when there are multiple insertion points, and you want to test all combinations of payloads.
• Payload Processing: Use built-in functions to encode/decode payloads, making it dynamic and relevant to the application's context.

6. Advanced Repeater Techniques

Repeater is where manual testing shines. It allows you to modify and resend individual requests to observe different outcomes.

• Session Handling: Often, when testing, sessions may expire. With the 'Use session handling rules' option, you can automate specific actions, like re-authentication.
• Rendering Responses: The 'Render' feature can be equally useful here to understand the visual changes after the request manipulation.

7. The Intersection with SubRosa's Cybersecurity Services
