Cyberattack Disrupts Supermarket Refrigeration Across Europe On November 2, 2026, a coordinated cyberattack targeted refrigeration systems in supermarkets across Belgium, Luxembourg, Sweden, Ireland, the Netherlands, Estonia, and Finland. The attackers remotely switched the units' evaporators to defrost mode, causing temperatures to rise to as high as 50°C (122°F), resulting in significant food spoilage. Major chains affected include Ahold Delhaize, Colruyt, ICA, Coop, and SuperValu, with reports indicating that around 40 Delhaize stores and 13 SuperValu locations were impacted. The attack method mirrors a previous incident in France from October 2026, where similar vulnerabilities were exploited. Authorities in Belgium and Sweden are investigating the incidents, and cybersecurity experts stress the need for improved security measures for operational technology devices. No group has claimed responsibility for the attacks, and the identity of the attackers remains unknown. 57 sources 73
