What happened
Several ICA and Coop stores in Sweden reported overnight attacks on refrigeration systems into 2 November, with freezers reaching up to 55°C and stock spoiled. ICA says the affected shops had connections outside its central network, but the controller brands, entry point and attackers have not been identified. The incidents follow similar French attacks, although no link has been confirmed.
