Hackers raise temperatures on fridges in hundreds of French supermarkets

Hackers targeted the refrigeration systems of hundreds of French supermarkets, raising temperatures to as high as 122°F (50°C). The attack affected multiple major retailers, including Carrefour, Monoprix, and Les Mousquetaires, resulting in millions of dollars in food waste and, in some instances, sparking fires. Investigators have identified a vulnerability in legacy control systems manufactured by the Danish firm Danfoss. The French National Cybersecurity Agency (ANSSI) is leading the investigation, while EU officials have characterized the event as a 'weaponization of food.'
