🛡️ CyberShield Website Analyzer

A professional Chrome Extension designed to analyze websites and classify them as:

📌 Project Overview

CyberShield is a browser-based website analysis tool developed as part of a Privacy and Usable Security project.

The extension automatically inspects the currently opened website and extracts multiple security-related features, including:

• URL characteristics
• HTTPS status
• Forms and input fields
• Suspicious URL patterns
• Phishing-related keywords
• Embedded content indicators
• Redirect behavior
• Domain reputation indicators

Based on these observations, the system calculates a risk score and provides a security classification.
