European Supermarkets Hit by Cyberattack Raising Fridge Temps to 50°C

Supermarkets across Europe experienced a cyberattack affecting refrigeration systems, causing temperature spikes up to 50 degrees Celsius. Chains like Ahold Delhaize and Colruyt reported issues in Belgium and Luxembourg, while Swedish grocers ICA and Coop faced similar disruptions. The incidents occurred overnight on November 2, 2026, with some stores only noticing the problem hours later. The attack mirrored a recent cyberattack in France from last month where hackers seized control of cooling units at hundreds of supermarkets, leading to fires and food losses. Authorities have not identified the perpetrators, though concerns around hybrid attacks following the Russia-Ukraine conflict have risen among European regional authorities. Sweden's national cybersecurity center is investigating multiple IT security issues in grocery stores, emphasizing the risk posed by exposed operational technology devices. These attacks highlight the vulnerability of retailers to cyber threats targeting automated systems like cooling units. Such disruptions can result in significant food waste and operational losses for supermarket chains. For investors, this raises awareness of potential financial risks linked to cyber vulnerabilities in retail operations and the importance of robust cybersecurity measures.
