Europe’s cyber vulnerability exposed

Europe is currently facing an unprecedented wave of cyberattacks. They have compromised supermarket refrigeration systems across at least 11 European nations, exposing critical weaknesses in seemingly ordinary food supply infrastructure. Hackers remotely raised temperatures to as high as 50 degrees Celsius, forcing retailers to discard tons of spoiled food.

Even French blood banks were targeted, although authorities apparently managed to protect their supplies. The incidents followed an October 11 attack affecting around 700 French supermarkets. The criminals exploited weaknesses in internet-connected refrigeration controllers.

Researchers had previously flagged vulnerabilities in Danfoss and Copeland refrigeration platforms. Danfoss confirmed that affected systems ran “outdated firmware”, illustrating how neglected security can threaten essential services.
