Скачать или смотреть XSSniper Masterclass Bypass WAFs and Find XSS Vulnerabilities Easily

Want to understand XSS basics without the fluff? In this video I show XSS fundamentals, how WAFs detect common payloads, and a live XSSniper demo — all in a safe lab so you can learn how attackers think and how to stop them.

0:00 Intro — what this video covers
0:35 Why XSS still matters
1:50 Quick XSS types primer
3:10 How WAFs try to stop XSS (high level)
5:00 XSSniper setup & run (lab only)
11:30 Evasion concepts & how to think about payloads (conceptual)
20:00 Wrap — what’s coming next

Coming soon - live bug bounty hunt
I’ll be posting a live bug bounty hunt video next where I test targets in-scope for a program. I already hit a high-severity reflected XSS in that scope - I’ll publish the full hunt and disclosure process as soon as I have permission from the vendor to disclose. If you want the real-world follow-up, subscribe and hit the bell so you don’t miss it.

If you learned something, drop a like and leave a comment: what WAF do you want me to test next? If you want me to break down any payload step-by-step (conceptually), say so and I’ll cover it in the next deep-dive.

Disclaimer (READ):
All testing shown in this video was performed in an isolated lab environment or on targets with explicit permission. Do NOT use these techniques against systems you do not own or have written authorization to test. Unauthorized testing is illegal and unethical — if you discover a real vulnerability, follow the target’s responsible disclosure or bug bounty process.

Enjoy the video, learn responsibly, and help make the web safer.
