Connectivity in these environments is often challenging, it isn't like connecting a consumer fridge to wifi. Sometimes you are bridging weird networks that multiple parties need access to. It should be secure but that isn't as straightforward as one might assume. Many of these systems have very long lives, so there are many limitations that reflect the technology that existed when they were built.
All of this is invisible to the average person but it is what makes the world work.
Maybe we throw it all away and go to 1990s-style grocery chain management, hire a bunch of people, and costs go up while reliability and monitoring shifts to humans. But that doesn't mesh with consumer expectations on price, which is probably how the whole system originated.
Further, once you have hundreds or thousands of devices, “just call someone to turn it up/down/off” doesn’t scale.
And yet, somehow it did scale just fine for a hundred years before we hooked everything up to the internet.
Yes, a lot of it exists to squeeze a bit more of a margin out of the business, but come on. The alternative isn't going back to the Middle Ages, it's shaving 0.1% off the profit margin. It's OK to wonder if the risk is worth it.
The increased profits that have occurred in recent decades have landed with the big food companies, not with the retail chains selling their products at very little margin.
They did promise to increase the cost of breakfast a couple years ago.
If only…
Which apparently why after >2000yrs of effort from both sides we now, finally!, have locks that no lockpicker can compromise.
Vulnerabilities will always exist. Systems will always be hackable. You solve the problem by patching what you can, and cleaning up after what gets exploited, if and when it gets exploited.
You must not mean what you have said here. If so, you are double-dipping.
I would be interested to know what the damage caused by this attack is compared to savings over a system where thermostats need to be adjusted on-site.
But more to the point, there's plenty of grocery stores that ask 20% more than their competitors and are doing just fine; in fact, constant price changes and promotions make it impossible for consumers to really compare if Safeway is cheaper than Whole Foods, so people usually go to the place that's physically closer, has better selection, or better vibes. I can't even know if a 12-pack of Coca-Cola is going to be $6.99 or $9.99 today.
The perspective of resiliency and how much will you lose if things go wrong seems kinda… new?
Funny that it should happen in France which has been at the forefront of European self resilience.
The biggest issue is that many of these IoT devices are badly secured. I spent years trying to convince people to build more secure IoT systems, but they always preferred cheap and easy solutions.
For me this has always been true of systems in general all across the decades that I've worked with technology. It's like pulling teeth to convince anyone in charge that backups or security are even a little bit important until after there's been a costly disaster, then it's all about "Why didn't you warn me this could happen?" - Umm... You mean like every single day for many months until you told me to shut up about it because my paranoia doesn't justify the tiny expense of ensuring you don't lose many tens of thousands of dollars or years of irreplaceable work or important records?

They highlight connection through a firewall, mention secure remote access methods, monitoring for data breaches, strong access controls, etc. Reasonable, but these are just recommendations, so the stores could have followed all of them or none at all.
An article about Danfoss vulnerabilities mentioned in a different comment (https://claroty.com/team82/research/freeze-the-controller-de...) says
> we searched publicly available internet-wide scanning platforms, including Shodan and Censys, for signatures associated with its management interface. It didn't take long to find what we were looking for. Numerous controllers [2765] were directly accessible from the public Internet.
So none at all is a possibility.
... And then the customer demands it be turned off, and the customer is always right...
Though I'm afraid things are getting worse, or at least it looked so a few years ago, back when I worked in this space. The hot thing in IIoT / Industry 4.0 was basically taking all webshit technologies and deploying them on industrial hardware, to "leverage mature innovation and OSS ecosystem" or such nonsense. The problem (one of many) being, once the engineers were done trimming excessive security measures that negatively impacted safety, they were still left with node.js running on industrial controllers, now even less secure in general than it was originally.
So you can find one, log in, and have a look for yourself.
You shouldn't.
But you can.
But you shouldn't. Okay? Don't.
I have been in meetings were the Data Security Officer refused to sign off on specific projects, without having a proper pentesting report in place, for example.
Because legally it would be their responsibility, if something would happen.
For the latter I would imagine you could have a short (maybe a month) logging period where you connect the fridges and collect data and then comeup with some offline system to manage them generally for better efficiency. You could even have a test group or single fridge that you keep connected to the internet for future data points (like in case of a giant heatwave or something)
Lets combine some testy topics: will LLMs make this any better? On the one hand, if it's easy for fridge manufacturers to churn out code, will the slop create enough cracks in the icemaker to sail the titanic through? Or will the lower barrier to pretty good security agents get more security into the IoT field (assuming it's taken advantage of?) Or will it not matter because the store manager will just set the web portal password to 123456?
Anything you might want to change with a freezer already requires someone physically there. It's like making a socket ratchet have a remote controlled direction toggle. Or a remote control button to light the inside of your money box on fire.
If you home refrigerator could be defrosted remotely, in what scenario would you ever do that?
