Simulacra is an open-source, modular anti-tracking system that uses ESP32 hardware to generate synthetic wireless noise, effectively masking a user's real devices within a crowd of fake signals.

Key Points

• The system creates a rotating population of fake BLE and Wi-Fi devices with realistic MAC addresses and advertising patterns to confuse passive trackers.
• It utilizes a multi-node architecture, including the ESP32-C5, ESP32-C6, and a "Vigil" controller board, coordinated via an encrypted ESP-NOW wireless link.
• The software features on-device self-learning that harvests ambient device structures to create new, anonymous decoy archetypes without storing identifying information.
• A "Vigil" touch-screen console provides real-time monitoring of fleet health, threat detection, and manual control over transmission presets like the high-volume "TURBO" mode.
• Users can deploy the system using a browser-based web-flasher or by compiling the firmware via ESP-IDF for custom, secure deployments.

Why it Matters

This project provides a sophisticated, hardware-based approach to personal privacy by addressing the growing prevalence of passive wireless surveillance and device tracking. By enabling users to blend into a synthetic crowd, it offers a practical tool for individuals to mitigate the risks posed by persistent trackers and location-based data collection.
