Cyberattacks crank French supermarket refrigeration systems up to 50°C

Reports describe cyberattacks that manipulated supermarket refrigeration controllers in France—raising temperatures to unsafe levels, spoiling food, and in some cases starting fires—impacting hundreds of stores; the incidents involve Danfoss AK-SM/AK-SC devices, a previously disclosed predictable authentication bypass, many internet-exposed endpoints, CERT-FR advisories, and ongoing uncertainty about the exact exploit used.
