I have a particular problem with a potential security breach. I bought a new device today that connects to my phone via Bluetooth. Nothing strange about that.
Surprisingly when I turned Bluetooth on with my phone and set it to search for discoverable devices, it came up with 12 Bluetooth devices that I have no idea what they are.
I entered one of the MAC addresses into a MAC address database, and none of the addresses was recognised. Wondering if I had made a mistake, I put the MAC address of the mobile phone, and it correctly showed that it was made by OnePlus.
I'm somewhat concerned about why there are so many Bluetooth devices around my computer working area and would love to hear some advice on what I can do to try and discover what they are and what they are doing? I wouldn't be so concerned if their MAC addresses resolved to a legitimate manufactorer but showing not found concerns me.
