European retailers reported refrigeration and freezer failures overnight into November 2. Carrefour Belgium confirmed a cyberattack, saying 15 of its more than 700 stores experienced limited disruption while all stores remained open.

Reuters also reported problems at Ahold Delhaize, Colruyt and retailers in Sweden and Ireland. Altered temperature settings caused food to spoil in some cases. An overall figure for the losses had not been established in those reports.

Carrefour said the disruption affected specific installations, mainly in frozen-food departments. None of its Belgian hypermarkets was affected. That distinction matters: failures in individual refrigeration units do not amount to the shutdown of an entire retail network.

The incident illustrates an operational risk from connected equipment. Interference with a control system can destroy stock without compromising payment infrastructure. However, the available statements do not establish who was responsible or a single verified cause covering every European incident. A connection with similar events in France in October should not be treated as proven.
