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

Supermarket refrigerators and freezers across Europe have been targeted by a cyberattack that raised the temperature of internet-linked units, destroying and damaging large quantities of food. On Monday, fridges and freezers at more than 100 shops in several European countries ran hot. Cyberattacks on supermarkets began last month, when hundreds of French supermarkets were left with spoiled food and damage to units which had overheated, costing millions of euros. So far, it remains unclear why hackers targeted the supermarkets, but attacks have spread across the continent and even to the United States.
