TL;DR
Refrigeration systems at more than 115 supermarkets and other businesses across at least six European countries were reportedly disrupted overnight on November 1–2, 2026. Reports describe internet-reachable controllers switched into defrost or heating modes, but the attacker’s identity and any role for AI remain unknown.
Refrigeration systems at more than 115 stores and businesses in at least six European countries were reportedly disrupted overnight on November 1–2, with some freezers switched into defrost or heating modes. The incidents affected retailers in Belgium, the Netherlands, Sweden, Luxembourg, Ireland and Estonia, with additional problems reported in Finland; authorities and companies have not identified who was responsible or confirmed that artificial intelligence was used.
Reports from Belgium describe stores whose refrigeration controllers could no longer be adjusted locally after temperatures changed. At a Delhaize in Eeklo, freezers reportedly reached 50 °C, while a Proxy Delhaize in Hoepertingen reported freezers at 15 °C and estimated that at least €60,000 of food had to be discarded. These figures come from media reports and the affected businesses, rather than a consolidated official damage assessment. A butcher in Antwerp reportedly shut its systems down in time to limit losses.
Retailers and industry sources described incidents across several countries. Ahold Delhaize said an IT incident affected refrigeration systems in several dozen stores; BleepingComputer put the number at about 40 in Belgium and Luxembourg. Carrefour Belgium reported 15 affected stores out of 700, while Coop Sweden said seven of its more than 800 stores were affected. ICA reported at least four stores, and 13 SuperValu stores in Ireland and one Selver store in Estonia were also reported affected. In the Netherlands, a Danfoss spokesperson told NOS that at least 17 businesses, mostly butchers and neighbourhood shops, had problems. The totals differ between reports and may include different kinds of businesses.
Belgian refrigeration installer Sabcobel said the incident involved evaporators remotely switched into defrost mode, using a mechanism it described as the same as in France in October. Its chief executive, Stephan Moelans, said technicians began disconnecting installations around 1 a.m. and that internet-reachable controllers at customer sites were attacked directly. He said Sabcobel itself was not hacked. Belgium’s federal prosecutor has opened a criminal investigation.

5 Ways AI Could Affect Europe’s Supermarket Refrigeration Security
A reported wave disrupted refrigeration controls at more than 115 stores and businesses across at least six countries. AI remains part of the framing—not a confirmed explanation for the incident.
A cross-border disruption with uneven counts
Retailer and media figures differ; they may describe different sites, systems, and types of business.
Belgium
15 Carrefour stores
Reports also cited about 40 affected Ahold Delhaize stores in Belgium and Luxembourg.
Netherlands
At least 17 businesses
Mostly butchers and neighbourhood shops, according to a Danfoss spokesperson.
Sweden
7 Coop stores
ICA separately reported at least four affected stores.
Luxembourg
Included in reports
Counts were grouped with Belgian incidents in some coverage.
Ireland
13 SuperValu stores
Reported among the locations affected.
Estonia
1 Selver store
Additional refrigeration issues were also reported in Finland.
How AI could matter—without assuming it was used
These are security implications to consider. The available reports do not establish AI use in this incident.
1. Faster discovery
AI tools could help attackers sort exposed internet-facing equipment more quickly. No evidence says that happened here.
2. More tailored attacks
Automated tools could adapt messages or probes to specific vendors and sites. The access route in these reports is unknown.
3. Quicker disruption
Automation can make it easier to repeat control changes across reachable devices, raising the stakes for remote systems.
4. Faster triage
Defenders could use AI to group alerts and spot unusual temperature or controller changes across many locations.
5. Better coverage gaps
Analysis tools may help identify sites or equipment outside central safeguards, a concern raised by some retailer reports.
Keep claims grounded
General warnings about AI-assisted cyber activity do not show that AI found, accessed, or changed these controllers.
Why refrigeration security becomes a food and business issue
Reports describe immediate operational consequences, though the full losses remain unsettled.
Remote control affected
Internet-reachable refrigeration controllers were reportedly targeted.
Temperature changes
Some units reportedly entered defrost or heating modes, or became unresponsive.
Stock at risk
One Hoepertingen store reported freezers at 15 °C and an estimated €60,000 in discarded food.
Trading disrupted
Stores faced emergency work, downtime, and possible spoilage. Combined costs are not confirmed.
A similar mechanism was reported in France
A previous French wave offers context, but it does not establish a shared attacker or campaign.
France, October 11–12
The Paris prosecutor’s office counted about 700 victims, according to the source material. Sabcobel said the November refrigeration mechanism resembled the French incident.
Exposed remote interfaces
CERT-FR warned that remote-management interfaces for refrigeration controllers were exposed online contrary to good practice, and said campaigns were probably ongoing.
Same actor or access path
No attacker has been identified. Reports do not establish whether the French and November incidents share an operator, or how each controller was accessed.
AI use or patch status
AI involvement is unconfirmed. Updates reportedly existed months earlier, but the affected products, deployment status, and their effect are not specified.
“We have identified an IT incident affecting the refrigeration systems in several dozen stores.”
Ahold Delhaize
Questions retailers can use while investigations continue
These checks address risks raised by the reports; no single measure is guaranteed to prevent an incident.
Review remote access
Check whether refrigeration management interfaces are exposed online and who can reach them.
Find systems outside central oversight
Inventory independent sites, third-party equipment, and controllers not covered by group safeguards.
Confirm vendor updates
Identify affected models and verify whether relevant updates have been applied at each site.
Investigators
Belgium’s federal prosecutor has opened a criminal investigation.
Businesses
Retailers and providers are assessing equipment, stock, and losses.
Evidence needed
Access routes, controller models, verified site counts, and any AI evidence.
Open questions
No public investigation completion date or final cross-country damage total is provided.
Risks to Stores and Food Stocks
Refrigeration is a core operational system: when it fails, shops can face spoiled stock, interrupted trading and costly emergency work. The reported losses at individual Belgian businesses illustrate how a cyber incident involving building equipment can have immediate physical and financial effects, even without reports of an intruder entering a store.
The reports also point to a potential security gap in equipment managed outside a retailer’s central network. ICA, Coop and Colruyt said some affected locations operated independently or used systems outside central safeguards; the Finnish reporting likewise described problems at smaller stores outside group protections. That does not establish a single cause for every incident, but it makes connected refrigeration controls a concern for retailers and other businesses that rely on remotely managed building systems.
AI is part of the article’s framing, but it is not an established explanation for this event. Belgium’s cyber centre has warned generally of rising attacks that can involve AI; no cited company, investigator or authority has said that AI was used to find or access the refrigeration controllers. Readers should distinguish that broad warning from evidence about this particular wave.

A French Wave Preceded the Disruptions
The European incidents followed a reported attack on supermarkets in France during the night of October 11–12, 2026. The Paris prosecutor’s office counted about 700 victims, according to the source material. Belgium’s Sabcobel said the refrigeration mechanism in the November incidents was the same as in France, but that comparison does not by itself establish that the same person or group carried out both waves.
France’s national cybersecurity agency, CERT-FR, warned on October 12 that remote-management interfaces for refrigeration controllers were exposed online contrary to good practice. It said attack campaigns were probably still ongoing. The source material also says manufacturers had issued updates months earlier; it does not specify which products were updated, whether every affected controller received the updates, or whether patching would have prevented these incidents.
Reported impacts vary by country and store. Some systems were said to have entered defrost mode, while others reportedly produced heat or became unresponsive. Retailer statements describe different affected sites and units, so the reported figures should not be treated as a final, consistent count.
“We have identified an IT incident affecting the refrigeration systems in several dozen stores.”
— Ahold Delhaize
Attribution and AI Use Remain Unknown
No attacker has been identified, and the source material reports no claim of responsibility. Belgium’s cyber centre has warned that the perpetrator may never be identified, while the federal prosecutor’s investigation remains open. It is not confirmed whether the November incidents were carried out by the same actor as the French October wave.
AI involvement has not been established. General warnings about AI-assisted cyber activity are not evidence that AI played a role in this incident. The available reports do not say how attackers obtained access to each controller, whether they used stolen credentials or another route, or whether every affected site was reached in the same way.
The precise scale and financial impact also remain unsettled. Media and company counts differ, and reported temperatures range from 15 °C to 50 °C. There is no single confirmed total for spoiled food, downtime or repair costs across the countries involved. The available source material also does not confirm whether updates had been applied to each affected controller.
Investigations and Store Checks Continue
Belgium’s federal prosecutor is investigating, while affected retailers and refrigeration providers are assessing damaged equipment and losses. Authorities and businesses will need to establish how the controllers were accessed, which models and configurations were involved, and whether the incidents share an operator or technical method. No public completion date for the investigation is provided in the source material.
Retailers with connected refrigeration equipment may review whether remote-management interfaces are exposed online, which systems sit outside central oversight, and whether vendor updates have been applied. Those are practical security questions raised by the incident, not proof that any single measure would have stopped it. Further reporting should clarify the verified number of affected sites, the scale of food losses and whether investigators find evidence of AI use.
Key Questions
How many stores were affected?
Reports put the total at more than 115 stores and businesses across at least six countries, with additional problems reported in Finland. The counts vary by outlet and may cover different types of businesses, so a final total has not been established.
Were the attacks confirmed to involve AI?
No. The source material reports general warnings about AI-related cyber activity, but no authority or affected company has confirmed AI was used in these incidents.
How did the refrigeration systems get disrupted?
Sabcobel said internet-reachable refrigeration controllers were attacked directly and that evaporators were switched into defrost mode. France’s CERT-FR had previously warned that remote-management interfaces were exposed online. The exact access method for every affected site is not known.
Who was responsible?
No person or group has been identified, and no one has claimed responsibility in the reports provided. Belgium’s federal prosecutor has opened an investigation.
Were the November incidents linked to the French attacks?
Sabcobel described the refrigeration mechanism as the same as in the French wave of October 11–12. That is a reported technical similarity, not confirmation that the same attacker was involved.
