A reported cyberattack disrupted refrigeration controls at stores in several French supermarket networks, according to reporting by Tom’s Hardware and La Dépêche. Coopérative U president Dominique Schelcher confirmed that refrigeration facilities in several stores were affected, but the number of stores, the attack’s cause and any food losses have not been reported.
A reported cyberattack on supermarket refrigeration controls has disrupted facilities at several stores in France, according to reports cited by Tom’s Hardware, while Coopérative U president Dominique Schelcher confirmed an impact within his network. The incident matters because refrigeration failures can put perishable stock at risk, but the number of affected stores and any confirmed food losses have not been disclosed.
Tom’s Hardware, citing French outlet La Dépêche, reported that several major retailers were targeted and that the affected equipment includes Danfoss-made refrigeration controls used by Intermarché, Leclerc and Coopérative U. The reporting described units being set to continuously defrost at 50 degrees Celsius. The supplied reports do not independently establish how many devices were affected or whether that setting applied across all impacted stores.
Schelcher said on Monday morning that refrigeration production facilities at several stores in the Coopérative U network had been affected since the previous night. He said teams had been mobilized to address the issue and that an investigation would follow. He called the incident “extremely serious.” His statement confirms disruption in part of the network, but does not specify the technical cause or the operational status of individual stores.
The report also said that deliveries and electronic shelf labels used for in-store pricing were apparently affected. Those details have not been confirmed in the material provided by a retailer or a named official. There is no reported accounting of spoiled products, store closures, customer impact or financial losses.
Risks to Chilled Stock and Store Operations
Supermarkets rely on refrigeration controls to keep chilled and frozen goods within required temperature ranges. If systems are made to defrost continuously, stores may need to check equipment and product temperatures, move stock or discard goods that cannot be kept safely. No food spoilage or safety impact has been confirmed in the available reporting, so the scale of any direct consumer effect remains unknown.
The reported effects on deliveries and electronic pricing, if verified, would broaden the disruption beyond refrigeration. Such systems support routine store operations, but the current accounts do not establish how widely those services were interrupted. For shoppers, the confirmed information at this stage is limited to disruption at several stores in one network, alongside reports that other chains were targeted.

Retailers and Refrigeration Controls
The account identifies Intermarché, Leclerc and Coopérative U as French supermarket groups using Danfoss-made refrigeration controls. That establishes a reported connection between the equipment and the stores named; it does not show that Danfoss itself was compromised or responsible for the incident. The supplied source does not describe how attackers gained access or whether the affected systems were connected through a shared service.
The incident was described as ongoing in the report. Schelcher’s statement places the start of the disruption at the previous night and confirms that response teams were working on the affected refrigeration facilities by Monday morning. Beyond those details, the material provided offers no account of earlier warnings, a previous related incident, or a broader timeline.
“A cyberattack has been affecting the refrigeration production facilities of several stores in our network since last night.”
— Dominique Schelcher, president of Coopérative U

Scope and Cause Still Undisclosed
The available reporting does not identify the attackers, their motive, or the method used to access the refrigeration controls. It also does not provide a confirmed count of affected retailers, stores or devices. While La Dépêche’s account, as summarized by Tom’s Hardware, names three chains, the supplied material includes direct confirmation only from Coopérative U.
It remains unclear whether the reported 50-degree defrost setting was observed across multiple systems or in a specific instance, and whether the delivery and electronic-label problems were caused by the same intrusion. Retailers have not provided confirmed figures for damaged stock, store closures, service restoration or customer consequences in the source material.

Retailer Response and Investigation
Coopérative U said response teams had been deployed to address the refrigeration disruption and that the incident would be investigated. The next useful updates would establish which stores and systems were affected, whether refrigeration settings have been restored, and whether products had to be removed from sale. No timetable for a full recovery was given.
Further statements from the named retailers or relevant authorities could clarify the reported effects on deliveries and electronic shelf labels, as well as whether the same cause affected each chain. Until those details are published, the incident’s full scope and any lasting consequences remain unconfirmed.

What did the attack reportedly do to the fridges?
The report said refrigeration units were set to continuously defrost at 50 degrees Celsius. The available information does not establish how many units had this setting or whether it applied to every affected store.
Has food been spoiled or made unsafe?
No confirmed food losses or safety impacts are reported in the supplied material. Any spoilage remains unconfirmed, and retailers have not provided figures on stock removed or discarded.
Were deliveries and electronic price labels affected?
The report said deliveries and electronic shelf labels were also apparently affected. Those impacts have not been independently confirmed in the source material.
Who carried out the attack?
