Module 5 :The Complete Guide to Cross-Site Scripting: Reflected, Stored, & DOM XSS
Cross-Site Scripting (XSS) is officially the #1 most dangerous software weakness in the world today according to the 2024 CWE Top 25. In this masterclass, we move beyond the "alert box" to show you how hackers actually use XSS to hijack sessions, steal credit cards, and take over administrative panels.
In this video, you will learn:
The Three Pillars: A deep dive into Reflected (Type-I), Stored (Persistent), and DOM-based XSS.
Advanced Variants: How "Blind XSS" allows attackers to target internal support dashboards and admin tools.
Real-World Breaches: The anatomy of the 2018 British Airways attack (380,000 victims) and the legendary Samy Worm.
The Attacker's Workflow: How to identify "Sources" and "Sinks" in JavaScript and use tools like Burp Suite and DOM Invader to find vulnerabilities.
Modern Defenses: How to implement context-aware output encoding, HTML sanitization (DOMPurify), and Content Security Policy (CSP) to stop attacks cold.
Whether you are a student, a developer, or an aspiring bug bounty hunter, this guide provides the technical foundation you need to master web security.
