Cross Site Scripting in Action How Hackers Exploit Websites

Cross-Site Scripting (XSS) is one of the most common web vulnerabilities — and one of the easiest to demonstrate. In this video, we show how a single line of code can change the behav-ior of a website, turning harmless input into a hacker’s playground. • This demo uses a safe, intentionally vulnerable test site. Do not attempt this on real websites. • Learn how XSS works, why it’s dangerous, and what developers can do to protect against it. • Subscribe for more cybersecurity tips, demos, and ethical hacking insights.
