Something different came to mind as I read this article - there has been recent chatter regarding impending Food security issues - it was even talked about by India's foreign minister recently:

I wonder if this attack is some kind of early warning about capabilities of disruptive forces.

Watch Dogs was ahead of its time. How long before one of these hacker groups claim the DedSec name as their own?

So, those fridges are in the supermarkets, right? Where people work, who have to empty a fridge before it can be remotely defrosted. Why can't those people just press a defrost button? What is the point of doing defrosting remotely when you cannot do it without the onsite support?

>Where people work, who have to empty a fridge before it can be remotely defrosted.

You don't empty a fridge with built-in defrost. Your home fridge defrosts itself every 12-24 hours and you don't have to do anything.

Normally, the temperature recovers in ~1 hour after a defrost. The attack is apparently chaining manual defrost commands one after another so that the interior gets way too hot.

Could it be that it defrosts only by raising the temperature for a few hours just a bit to get the same effect and they food stays there?

That's way the non-smart walk-in coolers work; every 12 hours they turn off the fans and heat the cooling element for about 15 minutes to melt any ice that's built up on it.

Ice anywhere else is treated as a separate problem and turning the cooler off to fix it is not typically an available option.

On the one hand, this might be an escalation of a war below the threshold of "Europe orders general mobilisation". On the other hand, it seems that you just have to sneeze in the general direction of anything 'cyber' to cause an incident, shame on us if we can't get very basic security in order.

hacked or backdoored? [1]

> The four-page security note, a copy of which was reviewed by Reuters, said that undocumented cellular radios had been discovered “in certain foreign-manufactured power inverters and BMS,” referring to battery management systems.

> cyberattack, which has hit Danfoss-made refrigeration controls

Danfoss AK-SM 720 or 850? Pull the ethernet cord, now.

The latter can be flashed with the new 800A series firmware which is safer, but I still would not put it on the public internet under any circumstances.

Supermarkets in the Netherlands were also hit. Seems like a Russian linked attack.

There was an article recently about a similar hack on fridges in American military bases I believe.
