A nationwide cyberattack targeting commercial refrigeration controllers compromised approximately 700 food retailers across France, causing widespread food spoilage and store fires. Exposed management units from vendors including Danfoss and Copeland were manipulated to trigger overnight defrost cycles, pushing temperatures to 50 degrees Celsius for six hours. This operational failure affected major grocery chains including Carrefour, Monoprix, Les Mousquetaires, and Coopérative U, with similar disruptions reported across Spain, Portugal, Poland, Germany, and Belgium.
Total retail losses reached millions of euros. While French Economy Minister Roland Lescure framed the event as a critical national security wake-up call, the incident highlights a severe disconnect between state cybersecurity doctrine and commercial execution. Audits exposed over 1,700 unpatched, internet-facing controllers managed by third-party maintenance contractors without proper authentication controls. The French national cybersecurity agency ANSSI and Paris prosecutors have launched joint investigations into the critical supply chain vulnerability.
