A coordinated cyberattack on hundreds of French supermarkets has exposed a striking vulnerability in the modern food supply chain: the systems that keep fresh food cold.
According to Reuters, refrigeration units at major chains including Carrefour, Monoprix, Intermarché, and Coopérative U were pushed to temperatures as high as 50 degrees Celsius overnight, causing food spoilage and, in some cases, fire risk. The incident underscores how a digital breach can quickly become a physical and operational crisis for retailers.

Critical Systems Put At Risk
Dominique Schelcher, chief executive of Coopérative U, confirmed that cyberattacks had disrupted “refrigeration production facilities of several stores.” In a LinkedIn post, he described the attack as “extremely serious and unprecedented,” arguing that targeting equipment essential to preserving fresh products and supplying consumers is unacceptable.
The disruption appears to have extended beyond France. Felix Aime, a senior cyber threat intelligence analyst at Sekoia Threat Detection and Research, told Reuters that the attack affected several European countries, including Spain, Portugal, Poland, Germany, and Belgium.
A Broader Warning For Food Supply Chains
European Commissioner for Agriculture and Food Christophe Hansen condemned the attack in a post on X, warning that food security needs greater protection at every level. His remarks reflect a growing concern among policymakers and security experts: food infrastructure is increasingly a strategic target.
That shift matters because supermarkets now depend on interconnected digital systems to manage refrigeration, inventory, logistics, and store operations. When those systems fail, the consequences can move quickly from operational disruption to lost product, financial damage, and public safety concerns.
For retailers, the episode is likely to sharpen focus on cyber resilience, especially in systems tied to temperature control and other critical store functions. For governments, it is another reminder that food security is no longer just a supply-chain issue. It is a cybersecurity issue as well.
CNBC said it had reached out to Carrefour, Monoprix, Intermarché, Coopérative U, and E. Leclerc for comment.
