Cyberattacks disrupted supermarket refrigeration systems across Europe on Monday, November 2, forcing affected stores to discard food after temperatures rose.
Retailers in Sweden and Belgium were among those reporting incidents. Some stores removed chilled and frozen products from sale.
The attacks have raised concerns about the vulnerability of remotely controlled equipment and potential disruption to food supply chains.
No group has claimed responsibility. Although similar incidents affected French supermarkets last month, investigators have not established a connection.
Affected retailers and technology suppliers are investigating the disruptions and implementing protective measures.
