It's a fridge. In a grocery store. You just get an employee to adjust the thermostat dial. How would the hackers demand payment if all you need to do is turn the dial back to "frozen"???
Edit: Yes i know the commercial fridges do not have "dials" and it's more involved. Still, if you have physical access to the thing, there's nothing that can be done from the outside that you can't revert.
