Today I looked at my Bluetooth settings on my Surface Pro 3 and noticed there were two devices paired to my computer that I don't recognize. One was an LG keyboard phone, another is a computer. I removed both devices. I have never authorized these devices to connect and I am the only user of my computer.

 

Is this a cause for concern? What access could these devices gain in this way? I leave my Bluetooth on all the time, is that unwise?

 

Thanks for any advice.

Set up a wi-fi protected access.

Those links are regarding wpa security on wireless networks. I don't understand how they relate to Bluetooth pairing?

Ok thanks. I still don't see more than a general relation to the first two links, but the third link basically says Bluetooth is highly vulnerable if not configured properly:

  • Already done: Configure devices so that the user has to approve any connection request
  • Answers one of my questions: Turn off Bluetooth when not in use
  • Not configurable (unless this refers to discovery mode): Do not operate Bluetooth devices in Mode 1;
    Already done: ensure discovery mode is enabled only when necessary to pair trusted devices
  • Not configurable: Trusted devices should be paired in safe environments out of the reach of malicious elements
  • Not configurable: Minimize the range of devices to the shortest reasonable distance
  • Already done: Consider installing anti-virus and personal firewall software on each Bluetooth device

Windows 8.1's Bluetooth settings are minimal at best:

  • "Allow Bluetooth devices to find this PC" is already unchecked.
  • "Alert me when a new Bluetooth device wants to connect" is already checked.
  • (Windows 7's "Allow Bluetooth devices to connect to this computer" doesn't exist in 8.1.)
  • I also have Avast Antivirus running on the computer since day one. Virus scans are fine according to two other products.
  • I will now turn off Bluetooth when not in use (rarely used).

 

So unless I'm misunderstanding, it seems these settings aren't working as described, because I had two devices paired which I never authorized. Which still leaves the questions: Is this something I should be concerned about or is it a problem inherent to Windows 8.1? Could either of these devices which paired with my computer have accessed or altered my data?

 

Thanks again.
