About forty Delhaize stores in Belgium were reportedly affected, along with Carrefour, Intermarché, Spar, ICA in Sweden and SuperValu in Ireland. Attackers alter settings, notably triggering defrost cycles; temperatures reportedly reached 50 to 55°C. On the night of October 11-12, around 700 French stores were hit. France's CERT-FR had warned about compromised Danfoss controllers. Danfoss said some devices ran outdated firmware. Nothing indicates a coordinated action.
