Burp Suite

“Burp Suite: the hacker’s tool for making websites say ‘excuse me’.”

Whether you are a developer or a security professional, understanding how applications are attacked is the key to defending them. Burp Suite is a fully featured web application attack tool: it does almost anything that you could ever want to do when penetration testing a web application. Burpsuit, in a nutshell, intercepts traffic between you and your browser and grants you the authority to alter and intercept packets.

Now, I’m not going to go over the basic setup because you can find it online; instead, we’ll look at deep insights and go over each tab one by one.

“Burp Suite: Making hacking less of a hassle since 2006.”

The Burp Suite’s Dashboard is the entry screen of this tool this is main section where you can get an overview of the tool’s status, activities and see if there is any automated scan running and what is it’s status. It serves as a central hub for Burp Suite.

The Target section of Burp Suite is a small but powerful tool that can be extremely helpful for testing websites. One of its most important features is the Scope section, which allows you to focus your testing efforts on a particular domain or website. By specifying a particular prefix for URLs or patterns to include or exclude from the scope, you can ensure that you’re testing only the areas of the website that are relevant to your testing efforts. The site map is another useful feature of the Target section, providing you with a tree-like structure that displays all the pages and assets present on the website.

To generate a site map, simply click on the “Site Map” tab and then click on the “Create” button. This can be extremely helpful in understanding the layout of the website and identifying potential vulnerabilities, such as cross-site scripting (XSS) attacks. Additionally, the Spider tool can be used to find all the directories and files available for the target website. By using the site map and scope sections together, you can focus your testing efforts on specific areas of the website and gain a better understanding of its overall structure. Overall, the Target section provides an array of helpful features and tools for website testing, making it an essential component of Burp Suite for any security professional.

Heading ahead to the point when the main game begins Proxy (The heart and soul of burp). In simple terms, a proxy is a place that lets us intercept, view, and modify requests as well as responses.

The proxy section consists of three main components: the intercept tab, the HTTP history tab, and the options tab. The intercept tab allows you to intercept HTTP/HTTPS requests and responses, giving you the ability to modify them before they are sent or returned. The HTTP history tab shows all of the requests and responses that have passed through the proxy, allowing you to review and analyze them. Finally, the options tab allows you to configure the proxy settings, including the listening port and SSL settings.

The intercept tab is perhaps the most important feature of the proxy section, as it allows you to control the flow of web traffic. When intercept is turned on, all requests and responses pass through the intercept tab. From here, you can choose to forward the request or response as is, modify it before sending or returning it, or drop it altogether. This makes it easy to test for vulnerabilities such as cross-site scripting (XSS) and SQL injection by manipulating the traffic and observing how the web application responds.

Now comes the Intruder tab. Intruder is used to automate customized attacks to Request Endpoints.

The Intruder section in Burp Suite is an essential tool for penetration testers and security professionals looking to automate and customize attacks against web applications. It allows you to select a target request and define a list of payloads or values to use in the attack. You can choose from a range of attack types to insert the payloads, such as sniper and cluster bomb attacks. Additionally, the Intruder section includes advanced options such as rate limiting and response handling.

You can save and load attack configurations for future use, making it easy to repeat or modify attacks as needed. The Intruder section also offers various features for analyzing the results of the attack, such as the ability to highlight differences between responses and automatically extract data from responses. With its powerful automation capabilities and advanced customization options, the Intruder section is an indispensable tool for anyone looking to assess the security of web applications.

Next comes Repeater!!

The Repeater section in Burp Suite is a tool that allows you to manually modify and replay individual HTTP requests. This section is useful for testing and debugging specific requests, as well as for exploring the functionality of a web application. To use the Repeater section, you need to select a request from the Proxy history tab and click the “Send to Repeater” button. This opens the request in a separate tab, where you can modify the request parameters and headers as needed. You can also use the Repeater section to resend the request multiple times with different values, making it easy to test the application’s response to various input scenarios.

The Repeater section includes several advanced features, such as the ability to add comments and tags to requests, automatically handle session tokens, and highlight differences between responses. Additionally, you can use the Repeater section to compare the responses of two requests side-by-side, making it easier to identify changes in the server’s response to different inputs.

“Burp Suite: Because who doesn’t love playing with other people’s packets?”

Last but not least, Comparer is an useful option.

In Burp Suite, the Comparer tool is used to compare two HTTP responses, requests or other pieces of data to identify differences between them. This tool is particularly useful for identifying subtle differences between responses, such as changes in session tokens, headers or other data.

There are many other options that you can explore; they are not as commonly used as this, but they can definitely do some cool things…
