3. Repeater

With Repeater, you can manually tweak and re-send requests to your satisfaction.

Use Case:

Picture that you want to test an SQL injection vulnerability. You can capture the request using the Proxy and forward it to the Repeater. There, you can experiment with payloads such as ' OR 1=1 -- to emulate an SQL injection attack.

4. Scanner – Pro version only

Scanner serves as your automated aid. It examines your site and seeks to discover known vulnerabilities.

Use Case:

A quick scan of a client’s e-commerce site can reveal whether it is exposed to common issues, such as insecure cookies or outdated libraries, and if JavaScript needs updating.

5. Decoder

Sometimes, web data is encoded (like Base64 or URL encoding). Decoder helps you convert it into comprehensible text, and vice versa.

Use Case:

You may come across a cookie value encoded as gibberish: YWRtaW49dHJ1ZQ==. Input it into Decoder, and it translates to admin=true.

6. Comparer

This tool is utilized to facilitate comparisons between two sets of data (like two server responses).

Use Case:

Perhaps you are conducting a role-based access assessment. Two requests should be made, one as a standard user and another as an admin, to analyze them for similarities or discrepancies.

7. Extender

Extender allows you to add or develop plugins, creating an open-ended system to enhance Burp’s capabilities.

Use Case:

Incorporate the Logger++ Firefox extension to monitor each request your browser makes in a comprehensive log. You can also create a custom extension if necessary.
