- On Monday, November 2, 2026, a suspected cyberattack compromised refrigeration systems at SuperValu, ICA, Coop, and Delhaize supermarkets across Ireland, Sweden, and Belgium, forcing stores to discard large quantities of fresh and frozen food.
- This disruption mirrors large-scale attacks reported last month in France, where hackers seized control of cooling units; technical analysis suggests vulnerabilities in Danfoss equipment running outdated firmware allowed unauthorized remote access.
- At least 40 Delhaize locations and 13 SuperValu stores reported compromised cooling units, with temperatures reaching 50°C. One Swedish store manager said, "Everything is ruined" after discovering spoiled merchandise.
