Legacy Security Flaws Trigger Massive European Supermarket Cyberattack
A coordinated cyberattack compromised refrigeration systems in approximately 700 French supermarkets, causing temperatures to spike to 50°C and igniting fires. The breach exploited outdated, internet-exposed controllers from Danfoss, Copeland, and Dixell, resulting in massive food spoilage and estimated losses of tens of millions of euros. French authorities are investigating the incident, which also affected retailers in Spain, Portugal, Poland, Germany, and Belgium, highlighting critical failures in basic cybersecurity hygiene.
