Machine-in-the-Middle (MitM) BLE Attack

This report demonstrates a practical BLE relay (Man-in-the-Middle) attack against a KeyWe smart lock using two Raspberry Pi 3B+ devices, Kinivo BTD-400 adapters, Node.js tools (noble, bleno, gattacker), and simple commands to spoof the lock's BLE advertisement and proxy traffic; the author documents setup, commands, captured GATT traffic, and notes the attack's applicability to other BLE smart locks and the risk posed by auto-unlock features.
