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

Attackers remotely altered refrigeration controls at supermarkets in Belgium, Sweden, Estonia and other European countries overnight into Monday, November 2, warming fridges and freezers. No chain reported more than several dozen affected stores, and some discarded chilled and frozen food. Danfoss, a Danish maker of refrigeration controls, is among those responding to the incidents.
