Hackers heat up supermarket fridges, spoiling food across France

A cyberattack on Danfoss-managed refrigeration controllers disrupted hundreds of supermarket refrigeration systems across France (Oct 11–12), extending defrost cycles and delaying alarms, which caused widespread food spoilage, financial losses, equipment damage and reported fires; affected equipment was mostly legacy, unsupported models (AK-SM800, AK-SC355), CERT-FR issued containment and remediation advice, and investigations are ongoing with no public claim of responsibility.
