Fridges in French supermarkets hit by cyber attack

French prosecutors have opened a specific cyber-crime investigation into the incident, which the Paris prosecutor's office called a "large-scale cyber-attack affecting the refrigerators of several major food retail chains across France".

Hundreds of French supermarkets have been hit by a cyber attack that caused their fridges and freezers to heat up, spoiling fresh and frozen food estimated to be worth millions of euros.

As a result of the attack, managers arriving at branches of several supermarket chains on Monday morning were hit by a wave of hot air from the freezers.
