Cyberattack Disrupts Refrigeration at French Supermarkets, Causing Food Spoilage

On October 11–12, 2026, attackers targeted legacy Danfoss AK-SM800 and AK-SC355 refrigeration controllers in hundreds of French supermarkets (including Intermarché, Carrefour, and Coopérative U), raising temperatures to 50°C, causing widespread food spoilage, fires, and millions of euros in losses; the incident affected over 300 stores, exploited known unpatched vulnerabilities in outdated firmware, and is being investigated by France's ANSSI, with attackers possibly using internet-scanning tools like Shodan to find exposed devices.
