Cyberattacks Hit Supermarket Cooling Systems Across Europe
On November 2, 2026, cybercriminals targeted commercial refrigeration systems across multiple European nations, causing temperatures in supermarket freezers and refrigerators to rise significantly. Retail stores in Belgium, Sweden, Ireland, Luxemburg, Estonia, and the Netherlands experienced sudden temperature spikes in their cooling infrastructure, following a similar large-scale attack in France.
Belgium and Sweden Record Widespread Retail Disruptions
Retailers across Belgium confirmed disruptions in dozens of locations. Delhaize reported an IT incident affecting roughly 40 stores, while Carrefour recorded problems in 15 outlets and Spar noted issues in five shops. The Belgian Ikea branch in Mons also registered a limited impact. Sabcobel, a refrigeration technology service provider, mobilized technicians beginning at 1:00 AM to handle the situation, while the Belgian public prosecutor’s office opened an official investigation. In Sweden, the ICA Kvantum store in Sjöbo stated publicly on Facebook that internal temperatures reached up to 50 degrees Celsius due to a suspected hacker attack. Seven Coop supermarkets in Sweden also reported refrigeration failures, leading to spoiled food and temporary store closures.
Cooling System Failures Affect European Markets
Beyond Belgium and Sweden, the November 2 wave affected other European markets. Irish broadcaster RTÉ confirmed that 13 supermarkets experienced cooling system failures, forcing operators to discard refrigerated and frozen goods as a precaution. In the Netherlands, refrigeration firm Danfoss reported that at least 17 smaller businesses faced similar technical anomalies. Meanwhile, Estonian authorities confirmed an incident where attackers gained unauthorized access to the control computer of an older Danfoss refrigeration system that lacked recent software updates. Security analysts reviewing the pattern note similarities to an October 12 incident in France, where Danfoss cooling units in roughly 700 stores were compromised, resulting in millions of euros in damages and spoiled stock.
Swiss Retailers Report Attempted Intrusion Without Losses
Supermarket operators in Switzerland avoided operational disruptions during the latest wave of incidents. Representatives for Coop, Migros, and Aldi Suisse told the Swiss news agency AWP that their facilities remained unaffected on November 2. However, the Swiss cooperative Coop confirmed that it registered and successfully blocked similar hacking attempts directed at its infrastructure. Coop emphasized that it maintains comprehensive security measures that undergo regular review and enhancement. Migros similarly stated that it continuously monitors digital threats and enforces appropriate protective protocols without disclosing proprietary technical specifications.
Investigators Find No Ransom Demands or Motive
Investigators have not yet established attribution or a definitive motive for the attacks. None of the affected commercial enterprises have received ransom demands, nor have there been any documented data exfiltration events pointing toward financial extortion. The incidents follow a series of similar disruptions affecting refrigeration units at United States military bases during the summer of 2026, prompting monitoring by defense officials. Security researchers examining the hardware footprint note that potential vulnerabilities extend beyond Danfoss systems to include older equipment controllers manufactured by Copeland and Dixell.
