Cyberattack on 700 supermarkets threatens food safety in France

A cyberattack affected close to 700 supermarkets in France and altered refrigeration systems, with temperatures reaching 50 degrees Celsius according to…

--- The context --- France relies on a vast supermarket network to preserve and distribute fresh products every day. When the systems that control refrigeration are manipulated, the danger stops being only digital and starts to affect food safety directly for thousands of shoppers who trust the cold chain. --- The facts --- The computer attack affected close to 700 of the 10.000 supermarkets in France, according to French finance minister Roland Lescure, who reported to Parliament. Attackers reportedly forced continuous defrosting cycles and raised refrigeration system temperatures to as high as 50 degrees Celsius, according to reports about the incident. Groupement Mousquetaires, which operates more than 4.000 establishments in Europe, reported effects at 300 Intermarché and Netto stores. Cooperative U recorded problems at 80 of its 2.000 supermarkets, and some stores had to throw away food, according to its chief executive, Dominique Schelcher. Carrefour and Monoprix were also affected. --- The positions --- Lescure ruled out risks to the national food supply, while acknowledging that the incident directly affects food security and describing it as a wake-up call for everyone. Schelcher argued, in indirect terms, that attacking equipment essential to preserving fresh products amounts to attacking the French food supply chain, calling what happened unprecedented, extremely serious and unacceptable. --- What remains unknown --- The Paris prosecutor's office opened an investigation to determine the scale of the damage, including damage linked to spoiled food and reported fires. The total amount of food discarded is still unknown, as is whether any consequences for consumer health will emerge from the episode. --- Unanswered questions --- Who carried out the attack and how did they gain access to the refrigeration systems? How much food was lost in total and at how many stores did it have to be discarded? Could a similar attack be repeated against other connected equipment in the food chain? --- EPM analysis --- The French government cybersecurity agency said it knew of numerous breaches linked to remote refrigeration control systems made by Danish firm Danfoss and United States firm Copeland. Danfoss said most of the affected equipment was old and no longer received security updates, and it recommended keeping firmware up to date and protecting systems with a firewall. 📌 EPM Take: In EPM's view, this attack shows that protecting food also means protecting the digital systems that preserve it, because old and exposed equipment can become a collective risk. The response cannot stop at investigating those responsible: it requires updating equipment, closing insecure access points and treating food cybersecurity as a shared public responsibility. If that correction is delayed, every connected store will keep relying on fragile defences against attacks that have already proved possible in practice.
