Attacking Web Apps for Pentesting & Bug Bounty — Burpsuite

Burp Suite is an incredibly powerful tool that is essential for any web application pen tester and bug-bounty hunter. In this article, we will see what is Burpsuite in detail.

What is Burpsuite?

Burp Suite is a powerful and widely used web application testing platform. Burpsuite helps security engineers identify potential risks in web applications.

Burpsuite is also widely used by bug-bounty hunters. Since Burpsuite is a fully featured web-auditing platform, it comes with many tools to help you discover bugs in web applications. We can also use third-party modules to further improve Burpsuite’s capabilities.

Burpsuite is an essential tool for any security testing team. In this article, we’ll take a closer look at the main components of Burp Suite, including the proxy, the intruder, and the repeater.

Burp Proxy

One of the key components of Burpsuite is the Burp Proxy. This tool allows you to intercept and inspect traffic between your browser and the target. By intercepting this traffic, you can understand exactly what data is being sent and received. This is useful for identifying potential vulnerabilities or misconfigurations in the application.

The proxy is particularly useful for identifying issues such as cross-site scripting (XSS) and SQL injection. XSS is a type of security vulnerability that allows an attacker to inject malicious code into a web page. SQL injection allows an attacker to inject malicious SQL code into a web application. By identifying these types of issues, you can take steps to mitigate them and improve the security of your application.

Also, Burpproxy allows us to forward requests to other Burp tools before sending them to the target. This allows us to further analyze the traffic and inspect individual requests and responses. This can be useful for identifying patterns or anomalies that might indicate a vulnerability.

Burp Repeater

Another key component of Burpsuite is the Burp Repeater. The Repeater is a powerful tool that allows you to test the application by sending custom requests and analyzing the responses.

One of the key benefits of the Repeater is its ability to identify vulnerabilities that might not be visible during automated scans. Automated scans are useful for identifying a wide range of common vulnerabilities, but they may not be able to detect all the issues.

The Repeater gives us greater control over the testing process. It allows us to fine-tune our tests to identify specific vulnerabilities. For example, we will be able to identify a vulnerability by sending a request with a specific input.

By analyzing the response, we may find that the application is behaving in unexpected ways. This will indicate the possibility of a vulnerability. This vulnerability might not be detected using an automated scan, but it could potentially be exploited by an attacker.

The Repeater can also test the application’s resilience to specific types of attacks. For example, you can use the Repeater to send a series of requests to test the application’s ability to handle SQL injection or cross-site scripting (XSS) attacks. By understanding the application’s behavior in these scenarios, you can take steps to improve its security.

Burp Intruder

One of the most powerful tools in Burp Suite is the Burp Intruder. This tool allows you to launch automated attacks on web applications to test their security.

With the Burp Intruder, you can test for a wide range of vulnerabilities. This includes SQL injection, cross-site scripting (XSS), and directory traversal. The intruder is highly flexible, allowing us to customize our attacks.

We can also use the intruder to perform specific audits such as brute-forcing, dictionary attacks, and fuzzing. The Intruder also provides us the feature to target specific areas of the application by selecting custom parameters.

Given the damage Intruder can cause if used carelessly, Burp Suite has implemented rate-limiting in the community edition. This means that you can only use Intruder for a certain number of requests, such as brute forcing a login form, in the free version of the tool.

If you’re planning to use Burp Suite to audit your business applications, consider purchasing a commercial license. This will give you access to all the features of Burp Suite without any rate limits.

Other Burp Tools

Burpsuite also comes with many additional tools. These include the spider, scanner, decoder, sequencer, and comparer.

These tools serve as utilities in general web application audits. For example, the spider can help discover and map the content and structure of a web application. We can use the scanner to perform automated vulnerability scans.

The decoder helps to decode and analyze encoded data, while the sequencer enables us to test the randomness of tokens and session IDs.

The comparer compares the behavior of different requests and responses. In addition to these, there are also many third-party modules available in Burpsuite. These modules further extend the capabilities of Burpsuite to help us test our web applications.


In conclusion, Burp Suite is a powerful set of tools for web application auditing. It includes a range of tools and features for testing the security of web applications. The proxy, the intruder, and the repeater are some of the main components of Burp Suite, each one with a specific function for identifying and assessing security risks.

With the help of these tools, security professionals and testers can identify and mitigate risks in web applications. With all-around web auditing features, it is also an essential tool for bug-bounty hunters.
