Hackers hijack refrigeration controllers at about 700 French supermarkets (Danfoss, Copeland and Dixell XWEB)
Overnight on Oct 11 to 12, attackers took remote control of internet-exposed refrigeration controllers at hundreds of French supermarkets (Intermarché and Netto, Coopérative U, E. Leclerc and others), forcing fridges and freezers into continuous defrost with setpoints around 50°C, spoiling fresh and frozen stock and reportedly causing small fires. CERT-FR names Danfoss AK-SM and AK-SC series plus Copeland and Dixell xweb controllers, says campaigns are probably still ongoing, and tells operators to take every controller off the public internet. Most affected Danfoss units are end-of-life models (AK-SM 800, AK-SC 355) that get no fixes; the entry vector and attacker are still unconfirmed.

Je confirme qu’une cyberattaque touche depuis cette nuit les installations de production de froid de plusieurs magasins de notre réseau @CooperativeU. Nos équipes sont pleinement mobilisées, en lien avec les frigoristes, pour rétablir la situation au plus vite. Une enquête devra permettre de faire toute la lumière sur cette attaque. S’attaquer à des équipements essentiels à la conservation des produits frais et à l’approvisionnement alimentaire des Français est d’une extrême gravité et est inédit. C’est inacceptable.
