Chains in Sweden, Belgium and Luxembourg say fridge temperatures rose overnight, similar to hack of French stores

Supermarket chains in Sweden, Belgium and Luxembourg have said the temperatures of their refrigerators and freezers in dozens of stores rose overnight, prompting fears of a cyber-attack similar to one that caused millions of euros of food losses in France.

Sweden’s Coop chain told the daily Aftonbladet on Monday that six of ​its stores ‌had been ​affected, while ICA said it was “aware that a limited ​number of stores were affected by an incident overnight which impacted their refrigeration and freezer systems”.

  • imagine having a freezer that’s susceptible to a cyber attack. Why the fuck is it connected to the internet? All it needs is a thermostat. The closest thing to a “smart feature” that might benefit is the ability to send a notification if power fails or temperature falls below a set value, neither of which should be hackable by an outside party.

    We bought a new Liebherr refrigerator, without a water connection and more importantly, no Wi-Fi connection.

    Looks like people didn’t learn any lessons from the past cyber-attack. Well, these kinds of attacks will continue as long as users don’t take corrective measures !

      I think these fridges are only supposed to be on the local network so they can be controlled centrally, and I assume the attackers gained access to the network. I HOPE these aren’t connected to a Datacenter like those cheap Chinese smart lights

    YTF does a refrigerator need to be on net control??? Isn’t it a set once and forget it device? Maybe to monitor it to report a failure… but to CONTROL it???

      I was gonna argue that a local remote control alternative doesn’t exist, but I really don’t know why you’d need freezers to be remotely controlled. They’re more of a set and forget.

        At a large scale you want some settings to monitor temps and controling defrosting and cleaning. I’m sure energy management is also helpful if there is a power cut or the backup generators are taking a minute out two to warm up.

        Walmart had that since the early 2000’s. Fucking bullshit then too. We once had a section go out and called corporate and they argued it was working because their computer said so. Fucking dumb asses we are looking at it and some asshat in Arkansas (we are in Texas) tells us we are wrong. They finally agreed to send a rep from headquarters to drive down and look for himself (who knows cost of that) just for that guy to go "yall right it broke. " Then.we got local guy come fix it.

    The question isn’t so much, “Why were these on the internet?”, so much as, “Why were these not securely connected?”

    At my last job, our AWS resources were firewalled off, only accepting connections from our internal VPN. To get on that, you had to be coming from the IP of an office or a DevOps team member’s home IP.

    The local firewalls could have only allowed traffic to the freezer VLAN from the remote monitoring IP.

    And that’s just two ideas off the top of my head. If my dumbass can do it, you don’t need a high level networking expert to fix this.

      I work as an IT consultant, and this doesn’t surprise in the least. Non-tech companies tend to have terrible security posture and governance. It seems like they only implement a basic security posture if they have to by law or they got hacked and lost a lot of money. I think the unintended consequences of this hacks are actually helping supermarkets to get their shit together in cyber security

    I work for the food industry, in automation. Our whole factory is connected. To the point that from my office, I can control most of the factory machines. From my office, from my laptop that needs to be connected through an ethernet cable to one of the tech network of the factory.

    If I want to connect from another device, I need to set up a vpn with credentials and an authorised IP.

    The only way to access our tech network from the outside is stealing my credentials and then ask some of my colleagues to authorise a device and IP for my credentials, something highly suspicious that would raise a lot of alarms.

    I’m not going to say that a system like this is infallible but turns an attack like this extremely unlikely. This is how you should have your systems “connected”. Not through a login portal exposed to the damn internet.

    The first and foremost sign of intelligence is the ability to learn. Somehow, those supermarket owners seem to lack this important trait.

      IT Security sits in cost center side of the business for these Legacy companies.

      It’s very much a " everything is fine why do we pay you?" Or everything is broken why do we pay you?" Situation

        Yeah, this is why I resist getting a job actually doing mainly IT security despite having been part of far too many incident response and recovery teams over the years. It seems like a no-win job at the moment because leaders rarely value it.

      You’re asking capitalists to slightly not maximize short term profit… good luck.

      Perhaps worse, you’re asking people who are full of themselves to question whether they might have been wrong/uniformed about something.

      Again, good luck.

          Are supermarket owners in Europe typically… capitalist?

          I am pointing out that the system that creates and maintains ‘supermarket owners’ does so in a way that also selects for and emphasizes certain traits in supermarket owners.

    They’re sitting exposed to the public internet with a well known and super basic password. If your shit is on Shodan, you better know in detail the multiple layers of protection in use. Today’s date is not a password.

    I think the takeaway here is how lucky these supermarkets have been. Any threat actor who’s organized would recognize the potential here and work to establish a proper foothold in the organization and try to pivot to corporate or payment networks. Instead they’re just turning off the refrigerators.

      They are grocery stores, not some break room fridge. This attack is both economic (for the spoiled food that needs to be thrown out and the price increase that will come with that reduced supply) and on health (because not all spoiled food will necessarily be recognized as such in an effort to avoid the first consequence, plus if the fridges containing milk go warm for a few hours, they can test some milk and it’ll probably still be fine, but that best before date is now likely useless at best or misleading at worst). Also, even if most food is fine, if some food isn’t, it will mess with some people’s heads pretty badly.

      If the intention behind the hack was disruption and damage, IMO this is one of the more effective angles they could attack.

          Milk will have problems if it’s the 50c fast-defrost cycle that the fridges in the first attack reportedly hit.

          If that was the case, why do they spend so much money on keeping it refrigerated before people buy it instead of being kept on normal shelves with all the other “refridgerate after opening” foods?

            Depends on the kind of conservation method they applied to the milk. Milk that was sterilized at lower temps is considered “fresh” and has to be kept refrigerated. Milk that has been pasteurized at higher temps is sterile and won’t cause bacteria to grow even if it’s kept at room temp.

            This however changes when you open the milk and it enters in contact with microorganisms that are naturally present in the atmosphere and that can proliferate in the milk; to avoid this, you need to keep milk at fridge temps so bacteria won’t grow too fast (if you keep it open in the fridge for too long, bacteria will grow anyway and the milk will go spoiled).

              Ah interesting. I know eggs can be (though the industrial washing they get changes that by removing an important protective layer), but figured the few times I got milk that went bad before the best before date it was because it wasn’t properly stored before I got it.

              Might depend on the pasteurization method maybe? Like the “bring it close to boiling” doesn’t kill everything in it but the chemicals might? (Speculation)

              Edit: apparently it has to do with the temperature it is pasteurized. There’s one version, most common in north America, that pasteurizes at slightly under a boil, which doesn’t kill everything in it and requires refrigeration before opening.

              And then there’s UHT milk, which is pasteurized at 138°C, and this apparently kills everything such that the milk doesn’t need to be kept in the fridge until it is open, and is more common in Europe and parts of Asia.

      Yeah except people turning them off now doesn’t preclude the freezers from your other possibility. It’s entirely possible someone somewhere has been sitting on access to those things for a while and only recently did a Claude script kiddie get in and start messing around with things.
