Cyberattacks Cause Fake Nuclear Alerts in Ukraine/Russia and Hit European Supermarket Freezers

A recent wave of cyberattacks has caused significant disruption and food spoilage across supermarkets in at least seven European countries, including Belgium, Estonia, Finland, Ireland, Luxembourg, the Netherlands, and Sweden. On November 2, 2026, refrigeration systems in numerous stores were reportedly compromised, with temperatures in freezers and fridges soaring to as high as 50 degrees Celsius (122F). This led to extensive damage, forcing retailers to discard large quantities of fresh and frozen products.

This incident echoes a similar large-scale cyberattack that impacted hundreds of supermarkets in France just weeks prior, resulting in millions of euros in food losses. The coordinated nature of these attacks has raised alarms among EU officials, who view them as a deliberate attempt to disrupt the food supply chain and undermine consumer confidence. While no group has claimed responsibility, authorities are investigating the perpetrators and the potential for these to be state-sponsored hybrid attacks.

The affected systems in both the recent and previous French attacks appear to have targeted older refrigeration controllers, with some reports mentioning vulnerabilities in products from manufacturers like Danfoss and Copeland. Supermarket chains are working to address the immediate issues, including removing spoiled goods and restoring cooling systems, as the wider implications for food security and supply chain resilience are being assessed.
