Why is KS03-566382 attached to my Bluetooth? It appears about 15 to 30 minutes after I'm on my computer and It's interrupting my service, my computer becomes slower and delayed. How can I find out who it is and remove it?

The Bluetooth System Preference/Setting will show any nearby bluetooth devices....just because you see them does not mean they are connected to your computer. In fact, you must pair a bluetooth device to a particular device.....they don't pair automatically unless you have previously paired them with your Mac (usually requires confirming a code).
Any bluetooth devices which are actually paired with your Mac will be shown as "Connected". You can disconnect any connected bluetooth device you don't want. You can also unpair a connected device as well so it won't automatically reconnect. See this Apple article for details:

If the bluetooth device does not show as "connected", then you have nothing to worry about. It is like how you may see multiple SSIDs for numerous WiFi networks. Just because you can see them does not mean you are connected to them, or they to you.

Not necessarily a hacker, it could be someone in the neighborhood who just put up their bluetooth device in pairing mode.
Bluetooth range is only around 30 meters so as stated it's likely someone near by being benign rather than a hacker army from a foreign nation
