HACKERS TARGET SUPERMARKET REFRIGERATORS ACROSS EUROPE, FOOD STOCKS SPOIL AS TEMPERATURES SOAR
November 3, 2026
BRUSSELS, NOVEMBER 3: A wave of cyberattacks targeting supermarket refrigeration systems has disrupted grocery operations across several European countries, forcing retailers to discard spoiled food after hackers allegedly manipulated refrigerator and freezer temperature controls.
Supermarkets in Belgium, Sweden, Luxembourg, Ireland, Estonia and the Netherlands reported incidents affecting their cooling systems on Monday. Several stores experienced sudden temperature increases, with some refrigerators and freezers reportedly reaching as high as 50 degrees Celsius.
Major retail chains, including ICA, Coop, Ahold Delhaize, Carrefour and Colruyt, reported disruptions at affected outlets. In Belgium, approximately 15 Carrefour stores were impacted, while several dozen Delhaize outlets experienced refrigeration problems. Ireland's Musgrave Group also confirmed that 13 SuperValu stores had been affected.
The attacks caused significant food losses, with retailers removing chilled and frozen products from shelves to prevent the sale of potentially unsafe items. A Belgian butcher reportedly estimated losses of approximately €15,000 after refrigeration systems at his business were compromised.
Cybersecurity experts have raised concerns about vulnerabilities in remotely managed refrigeration and building-control systems, which allow supermarket equipment to be monitored and operated through connected networks. Investigators have not yet identified those responsible, and no group has publicly claimed responsibility.
The latest incidents follow a similar cyberattack in France last month, when refrigeration systems at hundreds of supermarkets and independent stores were reportedly manipulated, resulting in widespread food spoilage.
The repeated attacks have intensified concerns about the cybersecurity of essential retail infrastructure and the potential consequences of digital intrusions into food-storage and distribution systems.
