FoilSuite: Open-Source Toolkit Runs Phishing Detection Locally in Browser

A PhD researcher built FoilSuite, a privacy-first security toolkit with three tools: FoilGuard for on-device phishing detection, FoilVault for zero-knowledge password management with risk-aware autofill, and FoilLab for hands-on security challenges. All tools run locally without external API calls or telemetry, using cryptographic primitives like AES-GCM-256 and Argon2id. The project aims to counter credential theft through UI deception and provide realistic security training.
