Cyberattack Thaws French Supermarkets' Refrigerators

A cyberattack targeted Danfoss refrigeration controllers, causing refrigerators in multiple French supermarket chains to defrost. The attack affected 250 to 350 stores, leading to significant financial losses and food waste. The attackers exploited older versions of Danfoss control software to trigger the automatic defrosting system, raising refrigerator temperatures. Intermarché, Coopérative U, and other major chains confirmed the incident, with investigations underway to determine the cause and impact.
