Hackers caused a temperature explosion in the fridges of hundreds of French supermarkets, leading to significant losses in food production. A hacker from abroad had attacked hundreds of French supermarkets, causing a temperature explosion in the fridges. The fridges were set to 50 degrees Celsius (120 degrees Fahrenheit), which resulted in substantial economic losses and led to unexpected incidents such as fires and broken food containers.

Authorities in France reacted urgently, asking supermarkets to stop internet connections and completely disconnect them. The action had to be carried out quickly because the systems were already in defrost mode, but the cause of the incident remained unknown. The cyber-attack's cause was identified as an external hacker who had gained access to software controlling the temperature of the fridges.

Authorities declared it was an 'unprecedented' and 'dramatic' operation that caused extreme and unforeseen damages. The case had immediate effects on French food production, leading to market losses and significant economic damage. French supermarkets had to refuse orders for fresh and frozen products, while consumers could only enjoy small portions of freshly cut food.

The incident also had an impact on European cybersecurity policies, pushing governments to increase protection of information infrastructures and establish new security norms to ensure online data and transmission safety. Furthermore, the incident required a review of supermarket refrigeration security, requiring that supermarkets install updated software versions or use more advanced security systems to protect their fridges against potential cyber attacks. Finally, the incident had a negative impact on all parties involved: supermarkets had to pay fines and respond to unexpected events, consumers lost the opportunity to purchase fresh and frozen products, and local economies suffered significant losses.
