Cyberattacks Target Supermarket Freezers Across Denmark and Sweden

A wave of cyberattacks has hit cooling systems in Denmark and Sweden. Hackers remotely turned up freezer temperatures to 50 degrees Celsius. This led to food spoilage in several European grocery stores.

In Denmark, five companies faced attacks on their cooling systems on Monday. The targeted firms included a food manufacturer, a catering business, and a biotech company. Authorities said the affected Danish firms removed the hackers quickly. This quick action prevented major disruptions to local food supplies.

The Confederation of Danish Industry issued a warning to member companies. It urged all businesses using industrial fridges to check their digital systems. Cybersecurity expert Jeppe Engell emphasized that companies must monitor their cooling equipment carefully.

Danish supermarket chains Coop and Salling Group reported no cyber incidents so far. Danish officials are still checking whether other local supermarkets were hit. The attacks also affected stores in Sweden, Belgium, Ireland, Estonia, and Luxembourg.

According to CPH Post, investigations into the cyber incidents remain ongoing.
