European supermarkets hit by new fridge cyberattack
Musgrave said 13 SuperValu stores were affected, and chilled and frozen products were removed from sale as a precaution.
- 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where hackers seized control of cooling units; technical analysis suggests vulnerabilities in Danfoss equipment running outdated firmware allowed unauthorized remote access.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.
- Supermarket chains are investigating the breach and have disconnected affected systems from the internet to contain damage. "As a precaution, chilled and frozen products in the affected stores have been removed from sale," Musgrave Group said.
- These incidents reveal security risks in connected retail infrastructure, where remote access capabilities create vulnerabilities for attackers. Store chains must update legacy firmware on operational technology devices to prevent further unauthorized manipulation.
