French Supermarket Fridges Hacked: Cyberattack Sparks Fires

A large-scale cyberattack has targeted hundreds of French supermarkets, causing refrigerators and freezers to overheat. The incident, reported by Reuters and CNBC, resulted in food spoilage and fires across multiple regions. Fridges at major chains including Carrefour, Monoprix, Intermarché, and Coopérative U heated up to 50 degrees Celsius (122 degrees Fahrenheit) overnight.

Coopérative U’s CEO Dominique Schelcher confirmed that the cyberattacks affected the refrigeration production facilities of several stores. He described the attack as "extremely serious and unprecedented," noting that targeting equipment essential to fresh product preservation is unacceptable. Les Mousquetaires, which owns Intermarché and Netto, stated that around 180 stores were affected. They expect damages to reach several million euros in losses, though precise figures are pending from court-appointed bailiffs and insurance experts.

The attack appears to be part of a broader wave of cybercrimes affecting Europe. Felix Aime, a senior cyber threat intelligence analyst at Sekoia Threat Detection and Research, said the attack affected several European countries, including Spain, Portugal, Poland, Germany, and Belgium. In the Netherlands, Ahold Delhaize reported a security issue within its network, taking systems offline, though stores remained open. Interpol’s global chief information security officer Bjorn R. Watn noted that AI is increasing the scale and speed of such attacks, describing it as an evolution rather than a revolution.

European Commissioner for Agriculture and Food Christophe Hansen condemned the attack, stating that "the weaponization of food has become a reality." He emphasized that food security requires more attention at all levels. The incident underscores a shift in cyber threats, where physical infrastructure, specifically those maintaining food supply, are now direct targets. This is not merely a digital breach; it is a physical disruption with immediate consequences for consumer safety and operational continuity.

Our read: the attack vector is significant. By targeting the cooling systems, hackers forced a physical response that could not be patched remotely. The damage is tangible: spoiled goods, smoke, and potential fires. The scale, spanning multiple countries and chains, suggests a coordinated effort. The financial impact, reported as several million euros by one group, is likely an underestimate given the broader regional reach. This incident will likely accelerate investment in industrial cyber defense for critical infrastructure, moving beyond IT networks to operational technology. The line between a cyber incident and a physical disaster is now blurred.
