They didn't actually hit 50C, right? I read it as setting the thermostat to 50C, which basically would just turn off the cooling compressor entirely - not heat the fridge.

I read somewhere else that they activated a quick defrost function and as those were industrial fridge, it seems they can heat to 50C

Wouldn't surprise me if they could go all the way to 200C as part of self-cleaning/self-sterilizing cycle.

Well, if there's water (or ice/frost) inside, you probably don't want to go above 100C. You'd turn it into a boiler, and pressure-test the door seals.

		I don't know about these particular fridges that got hacked, but most supermarket fridges I've seen around the world either have no doors, or if they do, their doors have wide gaps and no seals (they'd only make it harder for the shoppers to shop, and given the usual foot traffic, they'd wear out completely after a week). Exceptions I've seen: some top-opened supermarket freezers (particularly with hinged, heavy doors), and most fridges in small shops. I've seen a few that could turn into pressure bombs this way, but I very much doubt these had any networking/remote control capabilities.

So far as I can tell, the thermostat was set to 150 C, and it actually reached 50 C.

Though given how easy it is to make the error, "150" may have been a fat-finger typo for "50".
