French supermarkets suffer refrigerator shutdown after unprecedented cyberattack

Major French supermarket chains including E. Leclerc, Intermarché, and Cooperative U were hit by a cyberattack that remotely triggered the defrosting of refrigeration systems across hundreds of stores, forcing the disposal of spoiled food and raising food security concerns. The attack targeted refrigeration control systems from Danish manufacturer Danfoss, with the company noting that most affected equipment were legacy products no longer receiving security updates. French authorities have launched an investigation and are coordinating with European counterparts to address the vulnerability.
