What does raising the fridge's temperature look like for the attackers? I mean this in a couple ways.

How are they controlling so many at once? Like a list of IP's they can ssh into?

And then what form is the command taking? Some sort of linux command where they set a discrete value `fridgectl --temperature 50`

IDK not that important just find it hard to imagine what the sort of UX is here. Not a fridge-hacker-guy.
