What is the name of the program for executing a script under a certain condition (for example, the presence of a bluetooth-id)?

Question

Cryptography

I need the means of protection of such a plan:
For example, someone steals a laptop, and let's say that my bluetooth is paired with a laptop on my phone, and as soon as the laptop disappears from the phone's bluetooth radius, then some script is executed (for example, deleting mbr) on it.
Or vice versa, some script is not executed without my phone.
(One of the reasons why I need this, let's say I have a cryptocontainer open and I didn’t have time to unmute it, as a result, when the connection with my phone is broken, this will automatically be done)
Not necessarily with the bluetooth of the phone, maybe there are alternative methods. (press the button under the table hee hee)
Interested both for windows and at the bios level (I mean before loading the OS).

Answer 1

You will have to write software yourself that will constantly poll for the presence of a bt connection, and perform the necessary actions with the necessary triggers. To run the program before the OS, you will have to write your own bootloader, or use grub, but in this case you will have to write drivers for the bt adapter yourself.

Answer 2

You invent nonsense, leave the computer lock the user + autolock after a minute of inactivity.
The user is locked to do something by the system, this is already a reboot for anyone and the cryptocontainer cannot be opened in any way.
