Commercial refrigeration and freezer units across dozens of supermarkets in Belgium, Sweden, and Luxembourg experienced sudden, unauthorized temperature spikes overnight, driving internal heat levels as high as 50°C (122°F). Major regional chains including Ahold Delhaize and Colruyt in Belgium/Luxembourg, as well as ICA and Coop in Sweden along with select furniture and retail outlets, confirmed that their automated temperature control systems were compromised. The unexpected heating cycles ruined perishable inventories across multiple franchise locations, forcing store employees to clear out spoiled goods and temporarily shutter affected aisles. The incident closely mirrors a massive cyberattack from October 12, when hundreds of French supermarkets were targeted in a similar fashion, raising broader concerns over food supply chain security and industrial control vulnerabilities. Security researchers note that the attacks point toward exposed remote management ports or compromised third-party maintenance contractors who handle centralized operational technology monitoring for multi-store building networks.
