Cyberattack Targets French Supermarket Refrigerators, Forcing Mass Food Disposal

A cyberattack targeted French supermarket refrigeration systems by exploiting software vulnerabilities in legacy Danfoss AK-SM800 controllers. The attackers remotely raised refrigerator temperatures up to 50°C, resulting in mass food spoilage and disposal. This incident underscores the critical risks associated with end-of-life IoT devices remaining connected to the public internet. Since support for these specific controllers ended in 2021, thousands of similar vulnerable units remain accessible, highlighting the ongoing challenge of securing outdated infrastructure.
