v1.0.0 — Dead Man's Switch

Dead Man's Switch v1.0.0

Universal anti-forensic dead-man gate for ESP32 security firmware.
Successor to Suicide Marauder — the original ESP32 anti-forensic wipe system.

Features

• ROM SPI bypass brick — forensic obliteration hardware-validated on CYD
• Overwrite-then-erase + raw-read verify for all internal partitions
• SD full-LBA raw wipe (SDMMC) + file-level fallback
• Guardian — standalone firmware-agnostic dead-man gate (56-line .ino)
• Fork variant — gate compiled into ESP32Marauder, works on all flash sizes including 4 MB
• Password parity validation (PBKDF2-HMAC-SHA256, 63B max, whitespace rejection)
• 2-fail wipe — power-cycle-safe attempt counter
• GPIO dead-man switch — hardware arming line, cut/unplug/tamper triggers wipe
• Brownout hardening (ADC monitoring, NVS counter, fast_wipe)
• Fast wipe mode — skip SD, straight to flash erase + brick in seconds
• Dashboard hooks (SM_STATUS/INFO/ARM/DISARM/SET_PASSWORD/WIPE)
• T1/T2 tier system (reflashable vs. irreversible eFuse burn)
• Host provisioning tool (provision.py)
• Multiple input backends (serial, touch, button, Cardputer, mini joystick)
• CI matrix build with per-board SAFE_MODE bundles

Supported Boards

• ESP32 Classic (CYD, DevKit, etc.) — Hardware Validated

Planned Board Support

• ESP32-S3, ESP32-C3, ESP32-C6
• Flipper Zero (companion app)
• Raspberry Pi Pico W
• Any ESP32-based firmware

Integration

• Cyber Controller — flagship all-in-one security hardware controller
