Cyber-attack overheats supermarket freezers across hundreds of French stores

Hackers remotely altered refrigeration controls at as many as 700 French supermarkets, raising freezer temperatures high enough to spoil food and, in some cases, trigger fires and sprinkler damage. Investigators say the attackers exploited internet-connected equipment running obsolete firmware, unpatched software or default passwords, while disabling alarms or extending defrost cycles. No group has claimed responsibility, and attribution remains uncertain. The incident has exposed shared responsibility among retailers, contractors and equipment makers, as France delays broader connected-device security legislation.
