2026 French Supermarket Refrigerator Hack
In short
An unknown group hacked into refrigeration controllers at approximately 700 French supermarkets on 11 October 2026, setting them to defrost mode to spoil food stocks. This attack caused tens of millions of euros in losses and marked the first cyberattack to physically disrupt a national food supply chain.
In plain words
Hackers accessed supermarket cooling systems through the internet. They used very weak passwords to change the settings so the fridges warmed up overnight. This caused huge amounts of food to rot and be thrown away.
A simple example
A hacker logged into a Danfoss controller using the username 'admin' and the current date as the password. They then switched the system to defrost mode, causing the milk and meat inside to spoil.
Why it matters
It proved that digital attacks can cause massive physical damage to essential services like food supplies. It also highlighted the extreme danger of leaving industrial hardware connected to the internet with simple passwords.
Easy to mix up
Do not confuse this with a physical break-in or a simple power outage; this was a deliberate remote digital intrusion.
