On the night of October 11, attackers remotely accessed and manipulated refrigeration systems in hundreds of French supermarkets, leading to significant food spoilage and financial losses. The attackers targeted the Danfoss controllers, which manage the cooling systems, raising temperatures to as high as 50°C. This incident affected several retail chains, including Intermarché and Coopérative U, causing them to discard spoiled food. The French computer emergency response team, CERT-FR, issued an alert regarding the breach, urging operators to disconnect or tightly secure the affected Danfoss controller series, AK-SM and AK-SC. The National Cybersecurity Agency of France (ANSSI) emphasized the urgency of removing these controllers from the internet or restricting their access. While neither Danfoss nor French authorities have identified the perpetrators or detailed the method of attack, it is known that older models, which no longer receive updates, were primarily affected. Danfoss has acknowledged the issue, citing outdated firmware as a partial cause, and is working with customers to enhance security measures. French authorities, including the Paris prosecutor's office, have launched an investigation to determine the full extent of the damages and establish links between the attack and reported losses. The incident has prompted ANSSI to collaborate with European cybersecurity agencies, as the breach may have implications beyond France.
