Live Demos: Clickjacking & XSS When Headers Are Missing

Select an attack type below. Use the toggle to turn protection ON or OFF and watch what happens in real-time. These are real browser behaviors, not simulations.

Interactive Security Header Attack Demos

Explore interactive demonstrations of real attacks. Most exploit missing HTTP security headers β€” clickjacking, cross-site scripting (XSS), MIME sniffing, referrer data leakage, and more. Others go beyond headers: email spoofing (SPF/DMARC), HTTPS downgrade, cookie flags, and version disclosure, which the scanner grades separately β€” they matter just as much. Select an attack type below, then toggle the relevant protection on or off to see it activate in real time. These are real browser behaviors, not simulations.

What This Header Does

X-Frame-Options tells browsers whether your site can be embedded in iframes on other websites. Without it, a bad actor could use the browser's framing behavior to overlay your site with invisible elements under the right conditions. This demo shows how the technique works.

Real-world incidents where this weakness made exploitation easier

These are real attack paths where this weakness made exploitation easier, faster, or more scalable. They are not proof that one missing header alone caused each breach.
