Would You Trust a Smart Refrigerator After France’s Refrigeration Hack?

A refrigerator used to be a relatively simple appliance. It kept food cold, made ice, and occasionally reminded you that someone had left the door open. Today, some smart refrigerators can connect to Wi-Fi, send alerts to your phone, monitor temperature changes, and even show what’s inside without opening the door.

Those smart features can make everyday life more convenient. However, connecting an appliance to the internet also raises a question that rarely comes up when comparing storage capacity or finishes on conventional refrigerators: What if someone else gained control of that connection?

That question became harder to dismiss after hackers targeted connected refrigeration systems across hundreds of supermarkets in France on Sunday night, October 11, 2026. 

What Happened in France?

The Guardian reported on Monday, October 12, 2026, that hackers forced the temperatures of many French supermarket fridges up to 50°C (122°F) overnight in an unprecedented cyberattack, affecting several hundred stores nationwide, with fires and food losses reported.

According to ABC News, the refrigerator hacking affected several major food retailers in France. Les Mousquetaires, which owns Intermarché, said refrigeration systems at around 150 of its stores were heated to 50°C for six hours. Carrefour reported that 80 supermarkets were affected, while Monoprix said the attack reached approximately 5% of its stores. Coopérative U also confirmed that its supermarkets had been targeted. 

Later estimates cited by NPR suggested that the cyberattack affected around 500 to 700 stores in France between Sunday night and Monday morning.

Cyril Scheubel manages a large Intermarché supermarket outside Dijon. He told NPR that a surveillance company called him around 4 a.m. Monday, warning that temperatures were rising in the store’s freezers and cold rooms.

"I got in my car right away and went to the store. When I opened the freezers, there was no more cold - just hot air coming out," said Scheubel.

Supermarkets use commercial refrigeration-management systems that can control multiple refrigerators and freezers across an entire store. Maintenance companies may access control panels over the internet to monitor temperatures, adjust settings, and respond remotely to equipment problems. In this case, that remote access appears to have been turned against the stores.

Danfoss, one of the companies whose refrigeration-management systems were affected, said many affected units had reached the end of their supported life or were running outdated firmware. However, investigators were still examining the exact methods used in the attack.

Speaking to ABC News on October 13, 2026, Richard Buckland, Professor of Cybercrime, Cyberwar and Cyberterror at the University of New South Wales, discussed several possible motives. 

“Of course it could be cybercrime. It could be the first step in an extortion attempt to say to other companies, this is what we can do, pay us money, or we'll do it to you, or it could be state-sponsored attacks,” he said.

What was already clear, however, was how quickly interference with a connected system could have real-world consequences. A remote change led to spoiled food, damaged equipment, and major disruption across hundreds of stores.

Forbes reported that exact losses are unknown, but some impacted supermarket chains have suggested they face steep financial hits. Thierry Cotillard, CEO of supermarket group Intermarché, told French outlet BFM TV he expects losses to total tens of millions of euros nationwide in a single day (€10 million is equal to more than $11.1 million).

Nearly a week after the attack, NPR said no culprits have been named in the hack that has shocked the country.

The attack doesn’t prove that household smart refrigerators face the same vulnerabilities. Commercial supermarket systems operate differently and on a much larger scale. Still, the incident raises a question that applies to any internet-connected appliance: How much convenience are consumers willing to trade for the risks of connecting an appliance to the internet?

Why This Matters for Smart Refrigerators

The attack in France targeted commercial refrigeration-management systems, not the smart refrigerator in someone’s kitchen. These systems control refrigeration across entire supermarkets, and maintenance companies may access them remotely. A household refrigerator has different functions, users, and security risks.

The incident doesn’t prove that attackers can target household smart refrigerators the same way, nor does it mean every connected refrigerator is unsafe. However, both rely on software, internet access, and security updates to keep their connected features working safely.

The level of risk may also depend on what those features can control. Some refrigerators use connectivity mainly to send open-door or temperature alerts. Others allow owners to change settings remotely, view internal cameras, or connect the appliance to a wider smart-home system. The more access a connection provides, the more important it becomes to protect it.

In his ABC News interview, Professor Richard Buckland explained why cybersecurity can no longer be treated as something that only protects information: “I guess we've still got the mindset that cybersecurity is protecting data or protecting money. But actually, it's protecting fridges, lifts, airplanes, self-driving cars.”

The question isn’t whether every smart refrigerator will be hacked. It’s whether its connected features are useful enough to justify the added security risk. To answer that, we first need to look at what those features offer.

What Makes a Smart Refrigerator Useful?

Connecting a refrigerator to the internet can add features that aren’t available on a standard model. Depending on the refrigerator, owners may be able to:

• Receive an alert when the door is left open

• Check or adjust the temperature from a phone

• Get maintenance notifications

• View the refrigerator’s contents through internal cameras

• Track stored food and suggest adding items to a grocery list when supplies run low

• Monitor energy use

Some features have clear practical value. A door alert may prevent food from spoiling, while a temperature warning could help owners notice a cooling problem sooner. Internal cameras and food-tracking features may also help owners check what they have at home and decide what to buy while grocery shopping.

Other features may feel unnecessary if they’re rarely used. That’s why a smart refrigerator's value depends on the household. If the connected tools make everyday life easier, the added technology may feel worthwhile. But that convenience comes with risks that a standard refrigerator doesn’t have.

How to Use a Smart Refrigerator More Safely

Whether you already own a smart refrigerator or plan to buy one, you can reduce some of the risks of connecting it to the internet. The Cybersecurity and Infrastructure Security Agency (CISA) and the National Institute of Standards and Technology (NIST) recommend protecting smart devices with stronger account security, regular updates, and a secure home network. 

Start with these steps to use your smart refrigerator more safely:

• Replace any default password with a strong, unique one

• Enable multi-factor authentication if the account supports it

• Keep the refrigerator’s software and companion app updated

• Turn on automatic updates when available

• Protect your Wi-Fi router and consider placing smart appliances on a separate guest network

• Disable connected features you don’t use

• Remove personal accounts and reset the refrigerator before selling or disposing of it

Don’t rely only on the app to tell you whether the refrigerator is working properly. An independent refrigerator thermometer or temperature alarm can warn you if the cooling system fails or the connected monitoring becomes unavailable.

If you’re still choosing a model, check how long the manufacturer provides security updates and whether essential cooling functions will continue working without an internet connection. These details can help you decide whether the smart features are worth bringing into your home.

Is the Convenience Worth It?

The attack in France doesn’t automatically make household smart refrigerators unsafe. It does show that connected technology needs attention long after installation. 

Manufacturers need to provide security updates, while owners need to install them and protect their accounts and networks.

For some households, temperature alerts, internal cameras, and food-tracking tools may be worth the responsibility. Others may decide that a standard refrigerator already does everything they need. There’s no single answer for everyone. 

Knowing the benefits and risks, would you trust a smart refrigerator in your home?
