Supermarket Cooling Systems in Multiple European Countries Hacked and Set to Defrost Mode
Smart operations
Large supermarket chains across several European nations suffered cyberattacks targeting networked cooling and temperature monitoring systems, where settings were remotely altered from freezing to high defrost temperatures, spoiling large volumes of food supplies.
A series of cybersecurity incidents targeting refrigeration facilities has impacted supermarkets across multiple European countries. Following intrusions into hundreds of stores in France, similar attacks spread to Sweden, Belgium, Luxembourg, and Ireland. Attackers remotely breached networked refrigeration and temperature monitoring systems, switching temperatures from minus 20 degrees Celsius to 50 degrees Celsius defrost mode. This caused massive spoilage of meat, ice cream, and frozen goods, while also introducing fire risks. Authorities and analysts are monitoring the incidents as potential coordinated disruptions against civil food supply chains.
Key takeaways
- Attackers remotely breached networked refrigeration systems, altering settings from minus 20 degrees Celsius to 50 degrees Celsius defrost mode.
- The disruption affected major supermarket chains across France, Sweden, Belgium, Luxembourg, and Ireland.
- The incidents spoiled significant food stocks, posed fire risks, and raised official concerns over supply chain sabotage.
