Cyberattack on French Supermarkets Spoils Millions of Euros in Food

On October 11, 2026, attackers compromised Danfoss-supplied refrigeration systems at over 400 French supermarkets (including Intermarché, Netto, and Carrefour), forcing units to heat to ~50°C for hours, spoiling large quantities of food, causing some fires, and resulting in multi-million euro losses; the incident exploited outdated, unpatched refrigeration software and is under investigation with no claimant to date.
