Automatic Phishing Detection

WebShield.AI is a powerful Chrome extension designed to protect you from phishing websites as you browse the internet. With a proactive approach, it scans URLs, checks global threat databases, analyzes page content, and utilizes a trained machine learning model to identify malicious sites in real-time.

• Four-Layer Detection Pipeline:

  • Layer 1 — URL Intelligence: Analyzes URL structure for suspicious patterns, lookalike domains, and misleading subdomains.

  • Layer 2 — Global Threat Reputation: Cross-references sites against Google Safe Browsing and PhishTank for immediate threat assessment.

  • Layer 3 — Live Content Analysis: Fetches and examines page content for fake login forms and credential harvesting patterns.

  • Layer 4 — Machine Learning Model: Employs a trained RandomForest classifier to score URLs based on numerous features.

• Real-Time Warning Banners: When a phishing site is detected, a prominent red banner appears on the page, explaining the reason for the flag and providing a quick escape route.

• User-Friendly Interface: Features a live badge on the extension icon indicating the site's safety status (safe, suspicious, or phishing), a risk score, and specific flags that triggered the alert.

• Privacy-Focused: Only sends the URL of the visited page for analysis, ensuring that cookies, history, and personal data remain private.

• Lightweight Performance: Designed to have no noticeable impact on browsing speed, with background scans, smart debouncing, and a 30-minute cache for recently visited sites.

WebShield.AI is ideal for anyone who shops, banks, or logs into accounts online, receives links via various communication channels, or simply wants an extra layer of security while browsing the web.
