Burp Suite

Burp Suite is a toolkit for performing security testing of web applications. It is used by information security professionals to test the security of web-based applications, find vulnerabilities, and help to mitigate those vulnerabilities.
For CTF challenges and test exams, the Community Edition is enough, but for real engagements the Pro Edition is necessary.
The main components of Burp Suite include:

• Burp Proxy: This component acts as a man-in-the-middle between your web browser and the web server. It allows you to intercept and modify traffic between the two.
• Burp Scanner: This component performs automated testing of web applications for vulnerabilities. It can identify common vulnerabilities such as SQL injection, cross-site scripting (XSS), and insecure file uploads, among others.
• Burp Intruder: This component allows you to perform customized attacks on web applications. You can use it to test for vulnerabilities by sending multiple requests with different payloads to a target application.
• Burp Repeater: This component allows you to manually test and debug individual requests and responses.
• Burp Sequencer: This component analyzes the randomness of token values in HTTP responses, which can help to identify vulnerabilities related to the predictability of tokens.
• Burp Extender: This component allows you to write your own plugins and integrations for Burp Suite.

To use Burp Suite, you will need to configure your web browser to use Burp as a proxy.
It is possible to use the FoxyProxy extension for Firefox to quickly configure your web browser to use Burp.
Then, you can start intercepting and modifying traffic as needed. It is important to note that Burp Suite should only be used with permission on applications that you are authorized to test.
