Supermarkets in Belgium and Sweden report cyberattacks on freezers, -. Bloomberg On Monday, supermarkets in Belgium and Sweden reported sudden temperature changes in their refrigerators and freezers, raising fears of a cyber attack. In Belgium, the incident affected about 40 Delhaize stores, as well as selected Carrefour and Sapar supermarkets. In Sweden, problems were reported in several ICA stores and six LOL stores. In some freezers the temperature rose to 50 degrees Celsius. The incidents raise fears of a repeat of the disruption that occurred in France last month, when 700 stores were hit by cyber attacks that knocked out refrigeration systems and forced stores to throw away contaminated food. However, no company has taken responsibility for what happened. A month ago, shelves in Ahold Delhaize stores in the Netherlands were also emptied as a result of a cyber attack. The company has not yet said what caused the problem. It is also noted that in the US last week the Pentagon announced that it is investigating the reasons for the failure of food storage freezers at several military facilities.
