French Supermarket Cyberattack Turns Legacy Refrigeration Into Physical Risk

Paris, 13 October 2026 – A cyberattack on supermarket refrigeration systems across France has forced stores to discard fresh and frozen food, showing how vulnerable connected equipment can turn a digital intrusion into physical and financial damage. More than 400 outlets across several major retail groups were reported affected.

The attackers remotely triggered forced defrosting and raised temperatures in refrigeration systems. At least 300 Intermarché and Netto shops and more than 100 Coopérative U outlets were targeted, alongside several E Leclerc stores. Other chains reported disruption, while Paris prosecutors opened an investigation into the large-scale attack.
