HackWatch — Wrist-Worn Security Tool for T-Watch 2020
Security-focused firmware for the T-Watch 2020 providing WiFi deauthentication detection, BLE device fingerprinting, and TV-B-Gone IR blaster — a penetration testing tool on your wrist.
Overview
HackWatch (86+ GitHub stars) by virtualabs transforms the LILYGO T-Watch 2020 into a wrist-worn security research tool. It combines WiFi reconnaissance, BLE device fingerprinting, and IR remote control capabilities in a smartwatch form factor — essentially a "Flipper Zero on your wrist" for discreet security testing and research.
Key Features
- WiFi Deauth Detection: Monitor for WiFi deauthentication attacks happening nearby — alerts you when someone is attacking wireless networks in your vicinity
- WiFi Scanner: Scan and enumerate nearby access points with signal strength, channel, and encryption info
- BLE Scanner: Discover and fingerprint Bluetooth Low Energy devices — identify device types, manufacturers, and services
- TV-B-Gone: Built-in IR blaster that cycles through TV power-off codes — turn off any TV with a tap on your watch
- Watch Face: Functional time display when not in security mode
- Touch Navigation: Swipe-based menu navigation on the T-Watch touchscreen
Getting Started
Flash HackWatch firmware via Arduino IDE or PlatformIO with the T-Watch 2020 board support. Power on and swipe through the menu to access WiFi scanner, BLE scanner, TV-B-Gone, and settings.
Why This Project
HackWatch demonstrates how much security tooling can fit on a wrist-worn device. The WiFi deauth detection feature is genuinely useful for defensive security — it alerts you when someone nearby is attacking wireless networks. The BLE fingerprinting helps identify what devices are broadcasting around you. It's an educational and practical tool for security-aware users.
