Hack disables fridge controls at hundreds of French supermarkets
A coordinated cyberattack hit refrigeration systems at French grocery chains E. Leclerc, Intermarché and Coopérative U early Monday, forcing connected fridges and freezers into defrost mode for hours and raising temperatures to around 50°C. The intrusion spoiled food and triggered fires in some stores, and authorities say other chains were also affected. Danfoss, maker of the targeted AK-SM800 and AK-SC355 system controllers, said the hit units were running outdated firmware and that it is working with customers on mitigation.
