-This proof of concept exploits the failure to comply with the [**BSAM-PA-05 control**](https://www.tarlogic.com/bsam/controls/bluetooth-pairing-without-interaction/) within the BSAM methodolgy. Consequently, the device enables the pairing procedure without requiring user interaction and exposes its functionality to any agent within the signal range.

 ## Setup
 
 Ensure that your device is capable of functioning as an audio source, meaning it has a microphone, and that it is discoverable and connectable via Bluetooth.
 
 For instance, to be discoverable and connectable, the earbuds used during the talk must be outside of their charging case. By default, they only activate the microphone when placed in the user's ears, although this setting can be adjusted in the configuration app.
 
-Additionally, ensure that the device is not already connected, or alteratively, that it supports multiple connections.
