How Attackers Trick Users via Clickjacking (UI Redressing)

In a clickjacking attack, an adversary embeds your web application or payment form inside a transparent iframe overlay on a malicious website. When a victim clicks a seemingly harmless button on the attacker's page, they unknowingly click an administrative button or initiate a fund transfer on your embedded site.

Frequently Asked Questions

What is the difference between X-Frame-Options: DENY and SAMEORIGIN?

DENY completely prevents the page from being framed by any site (including your own), whereas SAMEORIGIN allows framing only if the parent site has the exact same origin.

Does frame-ancestors replace X-Frame-Options?

Modern browsers prioritize Content-Security-Policy frame-ancestors, but including X-Frame-Options ensures full backward compatibility with legacy clients.
