Simulacra is a modular, multi-node ESP32-based anti-tracking system that creates a synthetic crowd of wireless devices to obscure a user's real devices from passive tracking and surveillance. It uses encrypted communication between nodes to coordinate decoys and detect potential threats.

Overview
Simulacra is designed to protect user privacy by generating a rotating population of realistic fake wireless devices that mask the user's real devices. It operates on multiple ESP32 boards, each with a specific role, and uses encrypted ESP-NOW communication to coordinate the fleet. The system passively detects tracking devices and provides a controller interface for managing the decoy network and monitoring threats.
Capabilities
- ▸Generates synthetic BLE/Wi-Fi advertising traffic
- ▸Coordinates multiple ESP32 nodes over an encrypted link
- ▸Detects and identifies tracking devices
- ▸Provides a controller interface for managing decoys and monitoring threats
- ▸Supports on-air fleet enrollment and secure communication
Best for
Simulacra is useful for individuals concerned about privacy and anti-tracking, especially in public spaces or when traveling. It can be used by researchers and developers exploring wireless security and privacy solutions, and by hobbyists interested in building and deploying anti-tracking systems.

Security considerations
Simulacra transmits synthetic wireless traffic and may detect tracking devices. Users must comply with local radio regulations and laws. The system includes a security model with asymmetric key management and encrypted communication, but the fleet transport key is shared and unencrypted at rest. Captured devices can be revoked to prevent compromise.
