Very cold war: Who’s attacking Europe’s supermarket freezers?

A cyberattack raised the temperatures of internet-connected supermarket refrigerators and freezers across several European countries, damaging or destroying large quantities of food. On Monday, more than 100 stores were affected, following a wave of incidents that began in France the previous month and left hundreds of supermarkets with spoiled food and damage costing millions of euros. Delhaize reported dozens of affected stores in Belgium and Luxembourg, while Carrefour and Colruyt also reported refrigeration problems. Swedish Coop stores and an IKEA site in Mons, Belgium, were affected too; the hackers’ motive remains unclear.
