From New York Post:
Hackers raised the temperature of refrigerators and freezers at hundreds of French supermarkets to as high as 50 degrees Celsius (122 degrees Fahrenheit) overnight, causing fires and spoiling food.
The Paris prosecutor’s office said on Monday that a “large-scale” attack was “affecting connected refrigerators in several major food retailers across France,” leading to food losses and fires. Prime Minister Sebastien Lecornu has instructed France’s National Cybersecurity Agency (ANSSI) to investigate, a person in his office said.
