This talk delivers a highly practical and incredibly accessible method for detecting various BLE trackers using a sub-$15 "Cheap Yellow Display." While the underlying concept of BLE detection isn't entirely new, the speakers have engineered a user-friendly, open-source solution that broadens detection beyond just Apple AirTags to include other manufacturers like Tile, and crucially, exposes the wider privacy risks associated with everyday BLE devices, including medical implants. The project's extremely low barrier to entry and clear demonstration of real-world privacy implications make this…
