- On the night of 1–2 November 2026, cooling systems failed at dozens of supermarkets in seven European countries.
- Fridges and freezers warmed enough to spoil food, and some retailers said outsiders had changed settings on the small computers that control the cold.
- A similar wave hit French stores in October, and no group has said it was responsible.
How the views differ
Officials and commentators who read this as an attack on Europe’s food supply
Failures landed in seven countries on the same night, weeks after a large French incident.
EU commissioner Christophe Hansen treated the repeated events as an intentional hit on the food chain and on shoppers’ confidence.
Stores that confirmed cyberattacks said outsiders reached internet-linked controllers and forced warm settings, including defrost, the mode that heats a cabinet to melt ice. On this reading, the point was economic damage and fear, not a local fault.

Investigators and technical reporters focused on exposed equipment and unknown culprits
The machines that set store temperatures, including older Danfoss and Sabcobel units, could be reached online, and some had weak security.
A person with that access could turn on defrost or override the set point.
Officials in Belgium and Estonia say the attackers are unknown, motives are unknown, and naming them may never happen. Some chains first spoke of “IT incidents,” which leaves room for separate breaches or mixed causes even where food was truly lost.

The spoiled food is solid. BBC, Reuters, the Guardian and the Financial Times all reported warm fridges, losses and the same overnight pattern across seven countries. A Delhaize figure of about €100,000 sits in that reporting. That part does not depend on who is blamed. Remote intrusion is supported in named cases, not yet for every shop. ERR, Estonia’s public broadcaster, reported a Selver freezer set to +50°C through a Danfoss controller.
