Cyberattack Disables Freezers at Supermarkets Across Seven European Countries

Dozens of supermarkets across seven European countries reported that refrigerators and freezers overheated overnight on 1-2 November 2026 after a cyberattack. Temperatures rose as high as 50 degrees Celsius in some units, forcing stores to throw away frozen and chilled goods. Affected countries include Belgium, Sweden, Ireland, the Netherlands, Estonia, Finland and Luxembourg.

Sabcobel, a Belgian company that manufactures some of the affected equipment, said the evaporators on the units had been switched to defrost mode. The method matches the attack that hit hundreds of French supermarkets last month and caused tens of millions of euros in losses. No ransomware demand has been reported; the damage occurs as soon as the cooling systems fail.

Retailers and Scale

In Belgium and Luxembourg roughly 40 Delhaize stores were affected. One Delhaize branch in Hoeilaart, Flanders, estimated losses of €100,000 in produce alone, excluding the cost of temporary closure. Carrefour reported 15 of its 700 Belgian stores impacted. ICA and Coop stores in Sweden, SuperValu stores in Ireland (13 locations), Kesko in Finland and shops in Estonia and the Netherlands also reported failures. An IKEA store in Belgium was among those hit.

Swedish national cybersecurity authorities are investigating. The EU food and agriculture commissioner, Christophe Hansen, described the repeated attacks as "a deliberate attempt to disrupt our food supply chain and undermine consumers' confidence in it."

Technical Method and Precedents

The attack targets the control systems of commercial refrigeration units, remotely commanding them into continuous defrost. Once the temperature rises, food safety rules require the stock to be discarded. Last month's French incident affected as many as 700 stores and produced similar temperature spikes. Investigators have not publicly named a perpetrator. Speculation has included state-linked actors, but no group has claimed responsibility.

Stores posted notices that freezers were out of order due to a cyberattack and began clearing shelves. Some branches reopened after discarding affected stock and resetting systems. The simultaneous timing across multiple countries and chains suggests a common vulnerability in the refrigeration control software or network access used by several operators.

Supply-Chain and Consumer Effects

Beyond immediate spoilage, the attacks force temporary reductions in available chilled and frozen products and add costs for retailers already operating on thin margins. Consumers in affected cities faced empty freezer aisles and notices apologising for unavailable items. Cybersecurity agencies in the affected countries are coordinating with retailers and equipment suppliers to identify the entry point and apply patches. The pattern raises questions about the resilience of industrial control systems in everyday retail infrastructure.
