A cyberattack has hit several of the largest supermarket chains in Sweden, causing significant damage and disrupting operations at a number of stores.
The attacks took place from the evening of Sunday, 1 November, until the morning of Monday, 2 November, affecting well-known chains. According to local media reports, hackers were able to remotely interfere with the temperature control systems of refrigerators and freezers, where thousands of food products were stored. Through this manipulation, temperatures were raised as high as 70 degrees, putting large quantities of goods at risk.
Similar damage has also been reported in Belgium and Luxembourg, where attacks using the same method were carried out at almost the same time. A similar scenario had previously been recorded in France as well.
According to Swedish media, financial losses are estimated at hundreds of thousands of kronor. In addition to the cooling systems, it is reported that the checkout systems have also been taken out of service, although it has not yet been confirmed whether this is directly linked to the cyberattack.
Because of the situation, the company announced the temporary closure of several stores. Its representatives have apologised to customers, saying that work is under way to restore services and return operations to normal.
Authorities and the affected companies are dealing with the consequences of the attacks, while the full extent of the intrusion and responsibility for the incidents remain to be clarified.
