It’s just crazy how many Bluetooth devices have broken (or completely absent) authentication and pairing security.

It’s very difficult to tell when they’re encrypted, too. Your Bluetooth keyboard and mouse could be broadcasting everything keystroke and click unencrypted to anyone within 100m or so.

And that’s just the accessories. There have been tons of exploits of phone and computer firmware over the years as well. Security is an afterthought at best with Bluetooth.
