New Wave of Refrigeration Cyberattacks Hits Supermarkets Across Europe, Forcing Stores to Pull Food

A series of cyberattacks targeted supermarkets across Europe, affecting refrigeration systems in countries including Belgium, Sweden, and Estonia. The attacks, which occurred overnight, resulted in changes to the settings on refrigeration controls, causing temperatures in fridges and freezers to rise. This led some stores to discard chilled and frozen food or remove it from shelves. The number of affected stores per chain was relatively low, with no chain reporting more than several dozen impacted locations. The attacks involved systems made by Danfoss, a Danish manufacturer of refrigeration controls.
