Supermarket Freezer Attacks Spread Across Belgium, Sweden and Luxembourg

Attacks on supermarket freezers have spread beyond France. Overnight into Monday, 2 November 2026, refrigeration systems at dozens of stores in Belgium, Luxembourg and Sweden showed sudden temperature rises, with some freezers set as high as 50°C. Retailers threw out spoiled stock, and several stores opened late or stayed closed for the morning. One Delhaize store in Hoeilaart, Belgium, put its lost produce at €100,000, not counting revenue lost while closed.

The incidents are suspected cyberattacks. Sweden's national cybersecurity center says it is responding to multiple incidents, and the refrigeration contractor that runs Delhaize's installations in Belgium has called the events a cyberattack. Its CEO said the units' evaporators had been switched into defrost mode, and technicians spent the night and morning disconnecting affected installations. One Swedish ICA store said its settings matched those seen in the French attack. As of 2 November, no group has claimed responsibility, and no authority has named a suspect or an entry point.

Neither retailers nor authorities have named the controller brands involved. That matters, because in France more than one vendor's equipment was targeted, so the same product line should not be assumed in Belgium or Sweden. Separately, Ahold Delhaize dealt with an October security issue that affected some IT systems, but no source has linked it to the refrigeration problems.
