Cyber Sabotage: Massive Attack on IoT Cooling Systems Paralyzes European Supermarkets
A sophisticated cyberattack has targeted the refrigeration infrastructure of hundreds of supermarkets across France and several other European nations. By exploiting vulnerabilities in Danfoss cooling management software, hackers remotely raised freezer temperatures to 50 degrees Celsius, leading to widespread food spoilage and hardware fires. The incident has caused tens of millions of euros in losses and prompted a high-level investigation by the French National Cybersecurity Agency (ANSSI). The breach highlights critical vulnerabilities in IoT-enabled food supply chains and the risks associated with outdated industrial firmware.
