Cyberattack Hits Supermarkets Across Europe

Getting your Trinity Audio player ready...

Europe, November 3, 2026: A major cybersecurity incident has disrupted supermarket operations across several European countries after hackers allegedly gained unauthorized access to refrigeration and freezer control systems. The attacks caused temperatures inside some refrigerators and freezers to rise dramatically, reaching as high as 50°C (122°F), forcing retailers to remove or discard large quantities of chilled and frozen food.

The incidents were reported across Belgium, Sweden, Estonia, Finland, Luxembourg, the Netherlands and Ireland. Several supermarket operators have confirmed cybersecurity or technical incidents, while investigations are continuing to establish the full extent of the attacks.

The incident has raised serious concerns about the cybersecurity of modern food supply chains and the growing risks associated with internet-connected industrial equipment.

Supermarkets Across Europe Affected by Cyberattacks

Several major supermarket chains have reported problems with their refrigeration infrastructure.

Retailers affected include:

• ICA and Coop: Supermarket chains in Sweden reported refrigeration disruptions, with some stores experiencing significant temperature increases.
• Carrefour: Around 15 stores in Belgium reportedly experienced refrigeration problems.
• Delhaize: Dozens of stores in Belgium and Luxembourg reported issues affecting refrigerators and freezers.
• SuperValu: Refrigeration systems in 13 stores in Ireland were affected.
• Colruyt: Five stores in Belgium reported problems with their cooling systems.
• IKEA: Its Mons location in Belgium also reported an incident affecting refrigeration units.

In some locations, stores had to remove fresh meat, dairy products, frozen food, and other temperature-sensitive products from their shelves to protect customers.

How Did Hackers Target Supermarket Refrigerators?

One of the most concerning aspects of the incident is the method reportedly used by the attackers.

Modern supermarkets often use internet-connected refrigeration controllers to monitor and regulate temperatures across multiple refrigerators and freezer units.

These systems allow operators to manage cooling equipment remotely.

However, when such systems have outdated software, weak security settings or exposed internet connections, they can become vulnerable to unauthorized access.

In the latest incidents, attackers reportedly manipulated refrigeration settings and, in some cases, switched cooling equipment into defrost mode.

This caused temperatures to rise sharply, potentially damaging food products stored inside the affected units.

Cybersecurity experts have warned that poorly secured operational technology systems can create serious vulnerabilities for businesses.

Temperatures Reached 50°C in Some Locations

Reports from affected European supermarkets indicate that temperatures inside certain refrigeration systems rose to approximately 50°C.

Such temperatures are far beyond the safe operating conditions required for storing chilled and frozen food.

As a precaution, several retailers removed affected products from sale and arranged inspections of their refrigeration equipment.

In some locations, supermarket workers were forced to empty refrigerators and freezers, resulting in substantial food waste and financial losses.

The incident also affected smaller food businesses and independent retailers in some areas.

Is This Connected to the Previous Cyberattack in France?

The latest European incidents come just weeks after a similar cyberattack affected supermarkets in France in October 2026.

During that incident, hackers reportedly gained control of refrigeration systems at hundreds of supermarkets and food businesses.

The attackers manipulated temperature settings, causing cooling equipment to overheat and resulting in substantial food losses.

Investigations into the French incident identified vulnerabilities involving internet-connected refrigeration controllers.

The similarities between the French and latest European incidents have raised questions about whether the attacks are connected.

However, authorities have not yet established whether the same individuals or groups are responsible for both incidents.

Who Is Behind the Cyberattacks?

At present, no hacker group has publicly claimed responsibility for the latest incidents.

Investigators are examining possible security weaknesses, unauthorized access and the potential involvement of organized cybercriminal groups or other actors.

Authorities have also warned against drawing conclusions about the identity or motives of the attackers before investigations are completed.

Belgian authorities have opened an investigation into the incident, while cybersecurity teams and affected retailers are working to understand how the systems were compromised.

Why Are Supermarkets Becoming Targets of Cyberattacks?

The incident highlights a growing problem for businesses that depend on connected technology.

Supermarkets increasingly rely on automated systems for refrigeration, inventory management, security cameras, payment terminals and building operations.

Although these technologies improve efficiency, they also create additional cybersecurity risks.

A successful attack on a single connected system can potentially disrupt several stores or facilities.

Refrigeration equipment is particularly important because food products can become unsafe or unusable if temperatures are not properly maintained.

Experts have recommended stronger network security, regular software updates, secure remote access and continuous monitoring of industrial control systems.

Could Similar Cyberattacks Affect Other Countries?

The latest incidents have raised concerns about the vulnerability of supermarkets and food distribution networks worldwide.

Many countries use similar internet-connected refrigeration and building-management technologies.

This means that cybersecurity weaknesses in industrial equipment could potentially create risks for retailers beyond Europe.

However, there is currently no confirmed evidence that the latest European incidents have directly affected supermarket chains in India or other Asian countries.

Businesses are being encouraged to review their cybersecurity systems and ensure that critical infrastructure is protected against unauthorized access.

Conclusion

The cyberattacks targeting supermarket refrigeration systems across Europe demonstrate how digital security threats can affect everyday life.

What might appear to be a technical problem involving refrigerators can quickly become a major business and food-waste issue.

As investigations continue, the incidents are likely to increase attention on the cybersecurity of connected industrial equipment and the protection of essential supply chains.

For supermarket operators, securing digital infrastructure is no longer just an IT responsibility. It is also an important part of protecting food, businesses and consumers.
