# Cyber-Attack Disables Refrigeration Systems Across Seven European Nations Supermarket freezers forced into defrost mode, causing widespread food spoilage and financial losses. - **Source:** [BBC News](https://www.bbc.co.uk/news/business) - **Published:** 2026-11-02 - **Topic:** [Software & Engineering](https://brifing.si/c/engineering) - **Original article:** - **On Brifing:** https://brifing.si/s/e91556a4-73d6-4b5b-b307-c7db54560163 ## Widespread Refrigeration Sabotage Dozens of supermarkets across seven European countries experienced a targeted cyber-attack on their refrigeration and freezer units. The breach caused systems to switch into defrost mode, raising temperatures to as high as 50C. This incident follows a similar pattern observed in French supermarkets during October, leading to significant inventory spoilage. ## Vulnerability in Remote Maintenance Most affected supermarkets utilize internet-connected systems to facilitate remote maintenance and troubleshooting. Stephan Moelans, CEO of manufacturer Sabcobel, confirmed that attackers exploited these network connections. While software updates were initially considered, the company determined that the vulnerability requires physical modifications to the units to prevent further unauthorized remote access. ## Impact Across European Retailers The attack affected major chains including Delhaize, Carrefour, and Spar in Belgium, alongside ICA and Coop stores in Sweden. In Ireland, 13 SuperValu locations reported issues, while Dutch butcher shops and Estonian Selver stores also suffered. Retailers are currently working to disconnect affected units from the network to contain the damage. ## Quantifying the Financial Damage Individual store losses are substantial, with one Delhaize branch in Hoeilaart reporting 100,000 euros in spoiled produce alone. This figure excludes additional operational costs incurred from temporary store closures. Retailers like Ikea and Kesko are actively investigating the extent of the damage while supporting individual branches in managing their inventory recovery. ## International Security Investigations National cyber-security agencies in Belgium and Sweden are actively monitoring the situation. The UK's National Cyber Security Centre is collaborating with international partners to analyze the incident, despite no reported breaches in Britain. Authorities are also investigating potential links to refrigeration malfunctions at US military bases reported earlier in August. ## Manufacturer and Retailer Response Sabcobel has been working continuously to disconnect vulnerable units from the internet. Many retailers have shifted to more secure connections following the initial French incident in October. Despite these efforts, some units remain susceptible, forcing companies to implement emergency protocols to ensure that remaining inventory stays within safe temperature ranges. ## Operational Containment Strategies Companies like Coop have stated that the situation is currently contained and under control. However, the incident highlights the fragility of interconnected retail infrastructure. Retailers are now prioritizing the physical modification of hardware to mitigate risks that software patches cannot address, ensuring that future remote maintenance does not become a security liability. ## Broader Implications for Infrastructure This event underscores the critical security risks inherent in the Internet of Things within industrial retail settings. As supermarkets rely increasingly on remote management for efficiency, they become prime targets for malicious actors. The incident serves as a stark reminder that physical hardware security is essential for protecting perishable supply chains. ## Sources covering this story - https://www.bbc.co.uk/news/articles/cq1kd1nee80eo?at_medium=RSS&at_campaign=rss — --- _Summary written by Brifing from the original reporting.
