Clickjacking (Missing Frame Protection)
Overview
Clickjacking embeds a target website in a transparent iframe on an attacker's page. The victim is tricked into clicking UI elements on the invisible iframe (e.g., approve a transfer, change settings, delete account).
Detection Strategy
Look for HTTP responses that do not set either:
X-Frame-Options: DENYorX-Frame-Options: SAMEORIGINContent-Security-Policy: frame-ancestors 'none'or'self'
Remediation
Use CSP frame-ancestors (modern, preferred) or X-Frame-Options (legacy).
X-Frame-Options: DENY
Content-Security-Policy: frame-ancestors 'none';
