Cyberattacks on supermarket refrigeration systems have hit stores across 10+ European countries, raising temperatures to 50°C and causing food spoilage.

Unknown actors have targeted refrigeration controls in European supermarkets, switching units to defrost mode and setting temperatures as high as 50°C. The first wave began October 11 in France, affecting roughly 700 stores and causing food spoilage plus millions in damage. A second wave expanded to at least 10 countries including Belgium, the Netherlands, Sweden, Luxembourg, Ireland, Estonia, Finland, Italy, Portugal and Germany, impacting chains such as Delhaize, Carrefour, Coop and SuperValu. Many controllers are end-of-life with exposed interfaces; no group claimed responsibility initially.
