SENTINEL: 실시간 피싱 감지를 위한 Manifest V3 확장 프로그램

Sentinel: a Manifest V3 extension for real-time phishing detection

Phishing pages get better every year. Sentinel is a Manifest V3 browser extension I built to layer multiple signals:

• URL heuristics / typosquat-style checks
• Optional Google Safe Browsing lookups
• Brand / page content signals
• Popup dashboard + in-page banner + block interstitial
