On the bright side I'm sure the manufacturer and others will have an increased security posture going forward.

It's not immediately obvious to me why fridges in supermarkets need remote control; a supermarket is a place where there are always people, it's not a base on Mars. And even if a remote is needed, it should probably not go further than the manager's office.

I don’t know to what degree control is needed, but remote supervision of cold holding temperatures is good to make sure food doesn’t spoil. Most places that don’t have networked fridges have staff manually logging the cold holding temperatures to make sure things are working.
Again, though, I don’t know about making changes though.

The other, more likely, answer is that there’s a diagnostic mode that allows raw control of the system and no one bothered to require physical presence to enable service mode.
With remote firmware update capability, at attacker could easily brick the entire fleet. With just service access it could be possible but would be more complex.

Having networked telemetry seems like a good idea, just not sure why they would need remote control too - that seems far more dangerous than necessary.

Wonderful world we live in where refrigerators and cars also become e-waste because a manufacturer gets tired of patching them

We're in a "post-patching world" in that the number of 0days coming out is so rapid, I'm not sure it would even matter.
The physical architecture itself is the problem. There needs to be better controls (physical and software) to access those systems. Airgap possibily.

Probably to inflict pain on the life of the voters so they can blame the government and manipulate the 2027 French presidential election in April. Maybe just a test.
Same as the high velocity train being sabotaged again just in the Spain national day. Hybrid war.

Wow, are you an optimist. The manufacturer has stated that they're past the period of security updates. And others... meaning the supermarkets? They outsource that. The people they outsource it to? Maybe they'll start paying attention to security.

2. Because they think (rightly or wrongly) that the benefits of monitoring and ease of maintenance and their contractor having direct access to the data outweigh the risks.
3. They think it outweighs the risk because IOT has been socially normalized, creating the wide perception that no, it's not that bad.
They almost certainly have insurance for this kind of event, and their insurer will almost certainly think real hard about the pros/cons of this, and will adjust rates accordingly. The grocer is free to take those rates into account when deciding on whether their next store will have an IOT HVAC.

Groceries see HVAC in the same way. If they can get their issue addressed or diagnosed by their HVAC contractor without him having to schedule and physically travel to their site, they'd prefer him to solve/start solving the problem immediately. Time is money and the faster the tech can diagnose the problem, the faster he can get on fixing it.
And yes, the prevalence of these systems means that many HVAC techs have the ability to turn off their customers' air conditioners/fridges. They don't use it maliciously, because that would be actual suicide for their business.

There is a ton of refrigerant piping, multiple condensing units, multiple evaporators, relays, and sensors connected to a controller that automates the refrigeration system. Not standalone refrigerators.
I shouldn’t need to list the benefits of remotely monitoring a system that can cause tens or hundreds of thousands of dollars if it fails.

We specifically want to prevent scenarios like: you take a leak, the leak turns into a shitting session or a phone call, you forgot you left the burner on.
2. Most of the time my wife and I make food together so if one person needs to take a leak the other one is around anyway.
3. For long slow cooking, we have plenty of comfy seating in the kitchen/dining area where we can get work done while being in sight of pots.
4. We have 2 pets we'd need to locate in an emergency, and so we tend to put electrical and fire safety higher than most people.

> Danfoss told AFP in a statement that most of the affected equipment was "legacy" products which "no longer receive software or security updates".
They sell fricken refrigerators for God's sake. Maybe I can understand planned obsolescence for a cell phone, but a fridge? And especially to grocery stores that operate on razor thin margins to begin with, the idea that they'll just dump their old working refrigerators because the manufacturer refused security updates is a guaranteed recipe for stuff like this.
quickthrowman 1 hour ago | parent
They use cold cases and have rooftop or outdoor condensing units and evaporators inside of the cold cases/freezers/etc. There’s refrigerant piping running all over the place and there’s a bunch of sensors and relays that are automated to manage the refrigeration system.
My assumption is the Danfoss control system they’re using is EOL, it’s the grocer’s responsibility to upgrade their automation equipment if it’s unsupported.

No, there is not always someone onsite with the experience and knowledge to monitor and change the system. Grocery stores do not have staff refrigeration techs onsite, they contract that out.

Dispatch an HVAC tech if an alarm comes up. Physical access should be the only way to shut down a system like this.

Your opinion does not change the fact that virtually every automation system can be access remotely. It can be done safely with proper access controls.

> Danfoss told AFP in a statement that most of the affected equipment was "legacy" products which "no longer receive software or security updates". It said its AK-SM800 and AK-SC355 fridge regulator systems were notably affected, with a version of the former using "outdated firmware". It added that it had long advised supermarkets to update from those models.
That being said I am curious what is typically the amount of time for software support offered on a newly released equipment and how common it is for super market to use obsolete software (especially for the part which carry some security risk like something with remote control). Also what about the insurance? Will they (fully) cover the financial loss? I don't know what is in their insurance contract and I am not a lawyer but it seems to me that using obsolete software make the supermarket responsible to some extent

It's a near guarantee. I've been in dozens of power plants where the engineering workstations or operator interface terminals are running Windows XP or Windows 7. More than zero of which were not properly air-gapped. If those sites (with sizable CapEx budgets) delay upgrading for various reasons I would expect grocery store chains to keep whatever they have running until it's broken to the point of not being fixable without a complete overhaul.
zer00eyz 1 hour ago | parent
I could see remote monitoring (of temps) and logging on the system (cycle time etc) but does one really need to control the defrost cycle? It's probably just a web interface on a single controller that used to be accessed by HVAC techs only.
> > "legacy" products which "no longer receive software or security updates".
Because it's the EU I have to wonder if they will finally mandate that software go into escrow and be released if support stops.

Hopefully it will extend to consumer tech like iPhones and other “waste as soon as {corp} is done with it”
_ache_ 56 minutes ago | parent
But the hack has already been disclosed and it's the responsability of the manufacturer to ensure that the fridge keep ever up to date or offline.
As with the USA Defense hack, it could have been prevented.

I can't for the life of me understand why these systems aren't air gapped, or at the very least network access is restricted to a small number of IPs or hardware keys.

AK-SM800 looks like a current product. Danfoss have a PDF dated 2026.06 about it: https://assets.danfoss.com/documents/latest/590332/BC3376298.... This mentions "All new Electronics platform supporting new Operating System (based on Linux)", and specifically advises against connecting it to the internet.. Reading between the lines, especially section 10.5, it sounds like there was a major security revamp in 'release 4.0'. The article mentions "outdated firmware", so perhaps that refers to things before 4.0.
AK-SC355 looks like a product from 2010 (that's the date in the PDF metadata, plus the examples in the manual mention 2009). https://3.imimg.com/data3/ID/LC/MY-3170595/danfoss-system-ma...
I haven't worked with supermarket control systems, so I only know what I've read in the PDFs, but it looks like this is not about throwing out entire fridges to update the control system. If you have the newer AK-SM800, it looks like the suggested action is to update firmware and follow instructions about keeping it well away from internet access. If you have the older AK-SC355, then keeping it away from the internet is even more important. Or, update to AK-SC355.

I worry that this kind of thing is going to be a recurrent problem. A lot of people have pretty strong intuitions, or even an explicit moral position, that they should never have to upgrade a physical machine that's working fine. Is there a threshold of vulnerability that will overcome that, or are we just going to see a lot more hacking of random infrastructure from now onwards?

On the other hand, wild that it doesn't revert to some sort of offline backup mode after warranty ends. Or that anyone bought it in the first place (that can't be standard in the industry, right?).

What if all manufacturers had to classify their product into internet connected i.e. smart or not. We mandate that manufacturer has to support updates for minimum 5 years or firmware source goes public. Have them put firmware source in escrow as well as have a way to update it.
If a manufacturer wants to reduce their liability then they have to release something to make it semi publicly supportable. With AI agents these days patching the firmware might one day be trivial.
Put some penalities with teeth behind this and maybe manufacturers will think twice before making everything smart.

I remember working on my car when I lived in an apartment. I'd take my tools out into the parking lot, and get to work. If I needed to use the potty, or get a snack, or whatever, I had to pack up the tools and take them inside. Then out again. It really stinks.
I currently live in a high trust neighborhood where I don't need to be present with anything outside.
It's so much better.
