lets connect everything to internet, what could go wrong?

u/templeofsyrinx1 9h ago edited 9h ago

From reading some of the articles on this, it's being reported the remote management software that can be used to control the temperatures was compromised because of the lack of firmware updates.

122

u/rockmasterflex 9h ago

But why would it need to be controlled remotely? It’s a fridge.

114

u/KeyMessage989 9h ago

Pretty obvious answer for commercial fridges is people aren’t always in the building so you can tell if you have a failure

65

u/Frost_moss 9h ago

That requires remote monitoring, not remote control.

u/KeyMessage989 9h ago edited 9h ago

And you wouldn’t want the ability to adjust the temp if needed for any reason when no one is there? Again, this isn’t your LG wifi fridge. It’s an industrial control setup. A grocery store may have 50-60 fridges like this, maybe more, you really want to have to manually adjust every single fridge or freezer based on what’s in there? These systems have been along way longer than the ones in our house

u/Flutes_Are_Overrated 7h ago

Fridges are designed to keep the environment at a set temperature.

-3

u/KeyMessage989 7h ago

Yes and sometimes that temp needs to be adjusted

12

u/Flutes_Are_Overrated 6h ago

It shouldn't. But let's say it needs to be from time to time. That doesn't require always online remote access. As someone else knowledgeable explained, you can do this in clusters with one physical point controlling each cluster.

A supermarket having unified remote control on 100% of their refrigerators is a stupid idea and this failure shows why it's a stupid idea.

u/RockemChalkemRobot 3h ago

Building Automation is far from being a bad idea. Maybe too much of it is front-facing, and vulnerable, but I dont see many people saying you should have to go to a bank to make a monetary transaction. Our global economy being vulnerable is much more dangerous than some grocery store.

Hire a human being to work in your multi-million dollar facility like you're supposed to. Stop trying to rationalize irrational decisions being made solely for greed by some CEO that doesn'tcare whatsoever about you.

u/KeyMessage989 9h ago edited 8h ago

Yes, integrated industrial control systems is irrational as opposed to a person whose job it is to change the temp knob on 100 fridges and be on call whenever they need adjustment. Yep, I’m irrational. Let’s do the same for oil refineries. Who needs ICS when you have a guy

u/tamebeverage 8h ago

Not who you're talking to, but I work in control systems. It's entirely possible to have a control loop that's fully local and entirely disconnected from the internet as well as a remote monitoring loop with no control access. We do it all the time. You can have a terminal on site to be able to control them all from a single access point or several, as your needs dictate.

Remote monitoring, send an alarm that something is wrong, then have your guy go out and do the tippy taps at the local terminal.

u/k_dub503 8h ago

You could have person at the facility that monitors stuff and could remotely make adjustments from a control unit within the facility. Put the units on an internal computerized system that is not tied to the internet. They don't need to physically go and manually adjust each unit.

fundamentally fulfillable with a separate temperature monitoring system. Wildly inappropriate to expose CONFIGURATION AND CO NTROL of the fridge to the internet when you just need to know if it’s failing to hit a threshold

If the temps are suddenly not right, chances are something broke and you have to send someone to check it out. You ain't gonna fix it by setting a new temp.

Also, it takes time before it gets to be too late.

If temps are above safe limits in the US a store has 4 hours before the product becomes unsellable.

Remote access was the problem in this case. Supermarkets are rarely completely empty of people, even in the middle of the night

u/Sleek_ 7h ago

I don't know about your country but here(Europe) there is no night guard. The place is just locked, plus some alarms i guess

Supermarkets rarely have night guards in the US either. It's stock crews and janitorial working over night.

u/TotalBismuth 8h ago

That just needs read access, not ability to change temperature. Heck just setup a simple monitor that connects to wifi. Completely separate from the fridge system.

u/ceyhanli 8h ago

Reminds me of the Target attack. They’ve used a third party company to save on electric bills, the lights would turn on when a customer approached the fridge. It could be something similar.

These are large complex industrial control systems, not the fridge in your house.

Remote temperature monitoring probably as a store probably has dozens of them and it’s easier if they self report everyday for logging etc.

u/ididntunderstandyou 8h ago

The cold chain is one of the most critical part of food distribution. It makes sense for all supermarket fridges to be managed by head office.

- Better tracking of the cold chain and automatic reporting of any issues

  • automated maintenance sent if needed
  • staff no longer paid to perform hourly temperature checks
  • doesn’t put the responsibility on an underpaid staff if a fridge is not on and thousands worth of food spoils
  • no chance a prankster can switch off a fridge and spoil the food (oh wait…)

u/perenniallandscapist 9h ago

Oh let's neglect cybersecurity, too when we get it. We are not ready for the next big conflict. We are too far removed from how it used to be, and tech is starting to change so fast even the engineers don't understand it all. Either way, simpler living is going to be the future. The ability to put food up that doesn't rely on the grid is going to be big again

u/monkeymetroid 9h ago

Thats certainly a 2026 headline. Its not about fridges, but id think twice before purchasing a "smart" range oven. Being able to remotely start a burner or oven poses risks that will never be worth the mild convenience.

1

u/oviforconnsmythe 5h ago

I don't ever see myself buying a smart appliance, particularly a fridge of all things. At least for an oven/stove it gives you the peace of mind that you shut it off if you leave the house in a rush. Though your point about how disasterous it could be if there was a bug or security issue is valid.

That said, I can see at least some rationale in smart fridges in commercial settings, particularly in France (and more broadly, Europe). Electricity is expensive af in France, and in some cases has variable pricing based on peak/off peak schedules during the day/night. Being able to automatically pre-cool fridges during off peak pricing periods and making software controlled adjustments in real-time (more sensitive than typical thermocouples) could save the store serious money. Especially when multiplied over a large number of fridge/freezers. It's surely more reliable and cheaper than wasting an employees time manually adjusting everything....up until something like this security breach happens. But even then, the company that manages the automation said the companies didn't keep up with firmware updates, exposing the flaw.

If there are people motivated to go after your blink cameras, there will be people motivated to do actual dangerous malicious shit. Is the risk high? No of course not, but its also not worth it imo

Also, ai has empowered many more "bad actors" not all cybercriminals are oceans 11 levels of scale and not every "bad actor" is a human at a certain scale

u/ohlookahipster 8h ago

They don’t use it to blow up your house. Hackers use smart appliances as ‘zombies’ in a larger bot net attack.

That Samsung smart fridge you glaze so much? It’s likely been used in a data breach. Hell, it was probably enlisted it in the recent Stryker attack on hospital EHRs.

Your smart oven could be used in the next oil pipeline hack without your knowledge.

3

u/monkeymetroid 8h ago

That is a much more likely risk if one got compromised, but i was also pointing out the very rare "deranged individual" risk who is now able to utilize ai to actually harm people such as preheating a oven or turn a burner on (not sure you can do that one with current models) while people are asleep. A lot of the wrong type of individuals now have a much lower barrier of entry to enact their wills and are also able to scale their very scary amd psychotic motivations if enough work is put in. Anyone who think this is not possible have a rigid lack of imagination. Not being likely is not a good excuse for a worst case scenario at where the tech of ai agents are currently at.

There's a search engine that scans open ports on folks networks. Right now, there are who knows how many in home cameras completely open to anyone who wants to look all because the security on them isn't set up right.

Well, there’s many thousands of “ethical hackers” that use similar tools and techniques as the nefarious hackers and focus on IT vulnerabilities.

Ethical hackers been critical in stopping or undoing ransomeware attacks, building free security tools, identifying MANY zero day vulnerabilities before criminals, and many other cybersecurity areas.

There’s also “hacktivists” who do use hacking to identify, report, and shut down criminal websites - particularly those involving sex trafficking or child exploitation.

I work in cybersecurity and we talk about ethical hackers quite often.

u/ohlookahipster 8h ago

Hackers have been behind notable data dumps. There’s also grey hats who jump to the other side and help with vulnerabilities.

But most of these high profile hacks are going to be 1) driven by greed via ransomware, or 2) typically state sponsored. So we’re talking kids who want millions or the DPRK who does it for the love of the game.

u/DisenchantedByrd 9h ago

Just the usual cuplrit, large corporates not managing their infrastructure.

A source close to the issue said refrigeration control systems from Danish manufacturer Danfoss were targeted. 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.

u/Drokstab 8h ago

Were they able to update without replacing the units? If it was a simple software update I understand but if they need to replace the units that's absurd.

u/David_W_ 8h ago

Given the phrasing "update from those models" I'm betting it's a hardware replacement, not a software update.

https://www.reuters.com/business/retail-consumer/french-supermarket-chain-intermarche-hit-by-cyberattack-150-stories-targeted-2026-10-12/

Edit: Ah...looks like they triggered some of the units to forcefully defrost. I guess that'll do it.

3

u/Duideka 8h ago

I have had a controller fail on a freezer before and it was stuck on electric defrost and I came back to a freezer at 80c and everything inside cooking. The electric defrosts put out a lot of heat.

There are often also heat strips in the doors to stop the doors from freezing shut so if you cut off refrigeration things can get hot quick.

This IoT bullshit has gone way too far. If you don't want strangers controlling your shit, don't put your shit on the effin internet.

2

u/ahj3939 7h ago

Why wouldn't you? How else do you monitor and maintain them?

Do you have someone go by every hour and check the temperatures and call for repair when there is a failure? Will the be in the store 24 hours a day to perform this duty?

Or do you have an electronic system that is constantly monitoring not only the temperatures but also the internal operating parameters of the refrigeration system and log an alarm when something goes wrong? This could even preemptively catch a failure before a unit fails and all the food contained within needs to be thrown away.

u/Sarge2008 4h ago

Do you have someone go by every hour and check the temperatures and call for repair when there is a failure?

I worked in the deli department of a grocery store when I was in college. We had a temp logbook that had to be filled out every 2 hours from open to close. It's not hard to have someone walk around the department and get temp readings from the cold cases and some of the prepared items.

Actual physical employees - as we've done for the past hundred years between the invention of refrigeration and the internet.

I'm not wrong. A chain of supermarkets having an automated system in place to monitor their critical systems is only logical.
