Interestingly, a major Dutch supermarket was also hit by a yet-undescribed cyberattack, prompting them to basically shut down every IT system. So not a hack of a control system, sounds more like an ordinary ransomware attack... but still tantalizing that two EU countries have their food supplies targeted the same day... the day of a big NATO "russia we dont mess around" conference, too.
Maybe, just maybe, fridges shouldn't be online. Cue immediate responses of: but don't you understand, management can now monitor it 24/7 and adjust in real time. To which I have about the same response:
I would maybe tone that down that sentiment a bit and limit the adjustement.
You actually do want to be able to monitor them remotely, like most industrial/commercial refrigeration, to detect failures faster and more reliably. They should still be at least secured with normal auth/autz in addition to perimeter security, though.
If I can know when a fridge failed within the hour (even at night) then I can also dispatch a technician same/next day more easily.
There is value in nuance and debating whether the solution should be scaled down to say a store ( or only available on local vlan or something), but I think the value of discussing that is kinda diminishing, when, apparently, the controls for all stores can be done from the same hit.
But to address your specific point:
being able to monitor does not ( or at least should not ) automatically equal put it on the web
Monitoring would be one thing, but there's almost no conceivable reason to allow setting the temperature or triggering a defrost cycle remotely. When was the last time you changed the temperature setting on your fridge or freezer? It's something you set once when you install it and then never touch again.
This kind of inspector gadget "smart tech" lunacy has infected basically all consumer products. It's got to stop.
This is pretty interesting as the Danfoss vulnerability was suspected to be related to a similar situation that occurred across US military bases in late August 2026.
immediately thought of this article as well. really interesting. I could imagine someone using options/futures or other obscure financial instruments to make some money off this. hard to think of other motivations
I think Russia is doing random stuff of the kind, my understanding is it’s just about sawing general chaos, not doing a strong action that would be discussed at a diplomatic level.
Looks like that specific vulnerability was found this summer, disclosed in coordination with the vendor and at least some models were patched [0] (unclear if all models were), but from early reports:
- they either didn't warn their customers this was a critical security patch,
- many of these fridges/freezers were directly accessible on the internet with their own 3G/4F SIM cards without further protection!
Good. I’m not happy that this happened. That’s a large financial loss. I don’t like thinking about all the good, edible food thrown away instead of nourishing people. But the infosec thing that keeps me up at night is the utter lack of SCADA security. “Relax! This dam won’t collapse as long as no one guesses our public IP address!”
Lots of industrial controls haven’t been updated since they were deployed in the 90’s. “And why should they be? If it ain’t broken…” Well, because they’re freaking broken!
So I’m glad that this happened in a tangible, public way people can easily understand without it involving something much more drastic. If your family asks about this, explain that you’re glad no one blew up a gas pipeline… yet.
There is certainly a need to raise awareness of the danger of connected/online devices. If something is connected to the public Internet then it can be attacked. If something has built-in wireless connectivity then it can be attacked. Unfortunately it really is as simple as that. Safeguards are needed accordingly.
Connected vehicles are the example that terrifies me the most. There have been numerous examples of lax security in this area already and a fleet of rogue cars or delivery trucks could obviously cause huge amounts of damage, injury, and loss of life.
There's a legacy of openness in car tech and software that was never designed with robust security and isolation of critical components in mind. I've heard that this has started to change more recently and that's reassuring if true. But this still feels like an area with far too little regulation or oversight given the past choices of vehicle manufacturers and far too much rush to connect everything up remotely even for minor convenience reasons.
In some cases there also now seems to be legally mandated connectivity for things like automated emergency calls after an accident. This should at least have a genuine benefit in the unfortunate situation that it's needed - but until vehicle security looks more like Fort Knox than a sandcastle it might still prove to be a bad choice in the end.
To not control any industrial processes remotely? I hope you realize that requiring that would make solar and wind farms completely non-viable, among many, many other things.
Seems like 95% of devices could be managed with a hardware filter that only allows through a handful of very rudimentary signals (more like Morse code than a full digital transmission), and then of course a properly designed on-device API that defines those signals and doesn't allow you to trigger a defrost remotely, when that should only ever be done with somebody physically present for example.
I'm interested to know how many "legacy" controllers no longer patched by the manufacturer are operating solar and wind farms today.
If it's a lot, maybe the manufacturers should be compelled to provide security patches if remote control is required to operate their products. For the sake of national security, of course.
Of all the things to put on a network, this ranks as one of the dumbest, ever. You don't need control of the unit done over a network, just the data on whether it is working or not. Anything else is simply asking for someone else to come along and break your stuff.
To boot, refrigeration has been wholly automatic for decades. It literally runs itself. It doesn't need any network connectivity other than to say "I work" and "I'm broken" and that's it. Allowing control commands to be sent over the network is, yet again, just asking for trouble.
> While they may be known across the world as ‘French fries’, there’s nothing French about them. The name ‘friet’ comes from patates frites, Belgian-French for ‘fried potatoes’. One possible explanation for the association could have been formed in the First World War, when American soldiers were introduced to ‘fried potatoes’ in Belgium, but thought they were in France because that was the language spoken in that region. Whether you call them Flemish or Belgian, our delicious fries are made from bintje potatoes per tradition, and are the tastiest you’ll find anywhere on the planet.
Maybe they shouldn't.

Adjust: possibly, withing a range
Shutting down: Big no no

Could this be the same group? Or someone inspired by reading that article? Or just entirely unrelated?

Crazy stuff

Will they never learn?
Yes you might need to be able to centrally monitor and manage things but that should be happening on a private network.
If it's a lot, maybe the manufacturers should be compelled to provide security patches if remote control is required to operate their products. For the sake of national security, of course.
* Fridges are read-only through their remote interface.
Both of these can be true if you must connect them to the internet.
To boot, refrigeration has been wholly automatic for decades. It literally runs itself. It doesn't need any network connectivity other than to say "I work" and "I'm broken" and that's it. Allowing control commands to be sent over the network is, yet again, just asking for trouble.
