Accepted Answer

Yes, the skill includes advanced techniques for discovering leaked UUIDs and testing for predictable patterns even when non-sequential identifiers are used by the application.

Question 4

Is Burp Suite required to use this skill?

Accepted Answer

While Burp Suite is highly recommended for professional exploitation and automation, the logic and detection steps can be applied using any intercepting proxy tool or manual browser manipulation.

Question 5

Does it provide code examples for fixing these security issues?
