The 6-digit pin code used to obfuscate Bluetooth communication between smartwatches and Android devices can be brute-forced into exposing messages in plain-text. An attacker would have to be fairly near the victim and log all intercepted data packets. The large-scale adoption of such an exploit could be fueled by the increasing number of smartwatch or smartbands. The research involved analyzing the raw traffic before being sent over the air via the baseband co-processor, built into most Android devices.”]
