openhaystack
AI Summary: OpenHaystack is a framework designed for tracking personal Bluetooth devices through Apple’s Find My network, enabling users to create custom tracking tags for various physical objects. It utilizes a macOS application and custom firmware for Bluetooth devices, allowing them to be discoverable by nearby iPhones that can report their location without requiring cellular coverage. Notably, OpenHaystack leverages reverse-engineering and security analysis of Apple’s offline finding features, though it remains experimental and untested.
