Course Description

This course is the follow-up to one of my previous courses – Case-Studies of Award-Winning XSS Attacks: Part 1. We will continue our XSS hunting journey and you will learn about more award-winning XSS attacks.

There are many people hunting for XSSs, but only a few of them are successful and get a 4‑digit ($$$$) reward per single XSS. What makes them successful? They focus on non‑standard XSSs and this is exactly what I present in this course!

I’m one of the top hackers at HackerOne (among more than 100,000 registered hackers), and I really know how to make money out there. If you want to become a successful XSS hunter, then this course is just for you.

In Part 2 of Case-Studies of Award-Winning XSS Attacks, you will learn about the following non-standard XSS attacks:

1. XSS via XML
2. XSS via location.href
3. XSS via vbscript:
4. From XSS to Remote Code Execution

For every single bug there is a DEMO so that you can see how to find these bugs step-by-step in practice.

Do you want to become a successful XSS hunter? Let’s enroll to this course and continue our exciting journey.

If you are interested in more award-winning XSS attacks, then I also recommend you to see Case-Studies of Award-Winning XSS Attacks: Part 1.
