Overview

Tech support scammers use browser APIs to make your computer appear frozen, then display fake virus warnings with phone numbers to call. These attacks target elderly and non-technical users who don't know how to escape.

ScamShield stops these attacks automatically:

HOW IT WORKS
- Monitors five browser APIs that scammers abuse: fullscreen, pointer lock, keyboard lock, beforeunload traps, and history spam
- Detects scam patterns: multiple APIs fired in quick succession, or rapid repeated calls to the same API
- Blocks the attack instantly — no popups, no decisions, no configuration needed
- Shows a notification so you know you were protected

WHAT IT BLOCKS
- Fullscreen takeovers that hide browser controls
- Pointer lock that makes your mouse disappear
- Keyboard lock that traps Escape, Alt+Tab, and other exit keys
- Beforeunload traps that spam "are you sure you want to leave?" dialogs
- History spam that breaks your back button
- Combo attacks that use multiple techniques at once

PRIVACY
- No data collection whatsoever
- No analytics, no tracking, no ads
- All detection happens locally in your browser
- Open source: https://github.com/robbalian/scamblock

PERFECT FOR
- Installing on a parent's or grandparent's computer
- Anyone who wants protection from browser-based scams
- Security-conscious users who want defense in depth

Privacy policy: https://scamblock.vercel.app/privacy.html

## Screenshots needed
1. Popup showing blocked events log
2. Notification when a scam is blocked
