Protecting the Cold Chain When Refrigeration Systems Come Under Attack
Recent cyber incidents across Europe have shown how vulnerable the refrigerated food supply chain can be when connected refrigeration systems are compromised. In mid-October 2026, attackers remotely took control of refrigeration controllers at as many as 700 French supermarkets, forcing units into defrost mode or raising temperatures as high as 50°C (122°F). The result was widespread food spoilage, some equipment fires, and losses estimated in the tens of millions of euros.
