Cyberattack shuts down refrigerators at French supermarkets
-
A coordinated cyberattack has disrupted refrigeration systems at multiple supermarket chains across France, with attackers reportedly remotely defrosting refrigerated units overnight. The incident is believed to have targeted Danfoss refrigeration controllers, according to reports.
The attack affected several retail chains, forcing refrigerated systems offline and raising concerns about food safety, inventory loss, and the security of internet-connected industrial control systems in commercial retail environments.
Key points:
- Refrigerators were remotely defrosted at multiple French supermarket chains
- The attack reportedly targeted Danfoss refrigeration controllers
- The disruption occurred overnight
- No specific malware, threat actor, or vulnerability identifier has been disclosed in the report
The incident highlights the growing risk posed by exposed building management and refrigeration control systems, which are increasingly connected to networks but often lack robust security controls. Operators of similar infrastructure are advised to review remote access policies, network segmentation, and firmware update practices for refrigeration and industrial controllers.
