A cyberattack reportedly disrupted refrigeration controls at stores belonging to several French supermarket chains, including Intermarché, Leclerc and Coopérative U. Coopérative U’s president confirmed that refrigeration facilities at several stores in its network were affected; the reported impact on deliveries and electronic prices has not been independently detailed.
A cyberattack reportedly disrupted refrigeration controls at stores belonging to several French supermarket chains, with Coopérative U confirming that refrigeration facilities at multiple locations in its network had been affected. The incident may also have disrupted deliveries and electronic shelf labels, according to French outlet La Dépêche, though the scope of those effects has not been established in the available reporting.
Coopérative U president Dominique Schelcher said Monday morning that a cyberattack had affected refrigeration production facilities at several stores in the chain’s network since the previous night. He said response teams had been mobilized to address the issue and that the company would investigate. Schelcher described the incident as “extremely serious.”
The report by La Dépêche, as summarized by Tom’s Hardware, said the attack targeted refrigeration controls made by Danfoss and used by French retailers Intermarché, Leclerc and Coopérative U. It reported that some units had been set to continuous defrosting at 50 degrees Celsius. The source material does not specify how many stores or devices were affected, or confirm whether that temperature setting applied across all impacted sites.
La Dépêche also reported possible effects on deliveries and in-store pricing managed through electronic shelf labels. The available account does not detail which delivery operations were affected, how many labels or stores were involved, or whether customers saw incorrect prices. The precise technical method used to access or alter the refrigeration systems has not been disclosed.
Risks to Food Storage and Store Operations
Refrigeration is a basic operational requirement for supermarkets, particularly for stores selling chilled or frozen food. If cooling equipment is impaired, retailers may need to inspect products and systems, adjust operations or discard stock, depending on how long temperatures were outside safe limits. The reporting does not establish whether food was spoiled or whether any products were removed from sale.
Potential disruption to electronic shelf labels and deliveries could extend the impact beyond refrigeration. Shelf labels are used to display prices in stores, while delivery interruptions could affect the movement of goods. Those reported effects remain short on detail, so their scale and consequences for shoppers are not yet clear.
The incident also highlights the operational exposure created when essential store equipment is digitally controlled. A problem affecting refrigeration systems can have direct consequences for daily retail operations, even when there is no reported evidence of a wider disruption to payment systems or customer data. Neither such effects nor any data theft are established in the source material.

Retailers and Controls Named in Reports
The account concerns several supermarket chains operating in France, rather than a confirmed Europe-wide outage. Tom’s Hardware, citing La Dépêche, named Intermarché, Leclerc and Coopérative U as retailers using the Danfoss-made refrigeration controls reportedly targeted. The source material does not provide statements from Intermarché or Leclerc confirming an impact on their stores.
Coopérative U’s public confirmation establishes that refrigeration facilities at several of its stores were affected, but it does not on its own confirm that every retailer named in the report experienced the same problem. The source describes an incident beginning the previous night and being addressed on Monday morning; it provides no later update on whether systems had been restored.
“A cyberattack has been affecting the refrigeration production facilities of several stores in our network since last night.”

Scope and Cause Still Undetermined
The available reporting does not identify who carried out the attack, how the refrigeration controls were accessed, or whether the activity involved a vulnerability, compromised credentials or another route. No group has been identified as responsible, and no motive has been reported.
The number of affected stores, the duration of any temperature changes and the status of the refrigeration systems remain unclear. It is also not established whether the reported 50-degree setting occurred at all affected locations, whether food safety was compromised, or whether deliveries and electronic prices were measurably disrupted. The source material contains no confirmed financial losses, customer-data impact or final findings from an investigation.

Retailer Investigation and System Checks
Coopérative U said teams were mobilized to address the refrigeration problem and promised an investigation. The next updates would need to establish whether affected controls have been returned to normal, which stores and equipment were involved, and whether any products or services were affected as a result.
Further confirmation from Intermarché, Leclerc, Danfoss or relevant authorities could clarify whether the incident extended across the retailers named in the report and how the systems were compromised. Until those details are released, the incident should be described as a reported cyberattack with a confirmed refrigeration impact at several Coopérative U locations, while the broader operational effects remain unverified.
