Overview
PhishDetector is an award-winning real-time security threat automation chrome extension. It deploys lightweight machine learning classifiers directly on the edge, enabling zero-day phishing protection without compromising user privacy or web rendering speed.
The Challenge
Phishing URLs change within hours. Traditional security architectures depend on massive, latency-heavy blacklist databases, leaving users exposed to new zero-day attacks while sharing private browsing history with cloud APIs.
The Engineering Solution
Engineered in-browser TensorFlow.js classifier agents. Extracted and normalized lightweight feature signals (URL length, subdomain structures, certificate characteristics) directly on the edge, providing zero-latency block warnings.
Key System Deliverables
- ✦Chrome Manifest V3 Extension running local TensorFlow.js classifiers
- ✦React frontend configured with Tailwind CSS for seamless user warning portals
- ✦Python Flask API backed by GCP and PostgreSQL to update model weights incrementally
Measurable Success
- ✓Provided absolute offline-first zero-day protection
- ✓Minimized lookup lags entirely by moving prediction algorithms to the client edge
- ✓Maintained total customer privacy boundaries with zero external browsing data leakage
