European supermarkets hit by fridge and freezer cyberattacks after earlier French incident
Retailers in Belgium, Ireland, Sweden, Finland and Estonia suffered attacks on refrigeration control systems that caused sudden temperature changes, nearly identical to a mid-October attack on French supermarkets. Carrefour, Spar and Ahold Delhaize were named as affected, and no group has claimed responsibility. CERT-FR advised disconnecting refrigeration controllers with public IP addresses and reconnecting only via a secure VPN after verifying configuration.
Supermarket fridges in Belgium and Sweden overheated in suspected cyberattacks
Refrigeration systems at supermarkets including Delhaize, Colruyt and ICA stores were remotely set to around 50°C overnight on 2 November, with some stores blaming a cyberattack. Attackers reportedly switched evaporators into forced defrost mode, the same method used against hundreds of French stores in mid-October, which involved Danfoss equipment and caused fires and food losses.
