Unidentified hackers breached refrigeration management software across approximately 400 supermarket locations in France, deliberately raising temperatures to 50°C for six hours. The attackers gained control of the remote management systems that operate the cooling equipment, causing widespread food spoilage.
Supermarket operators were forced to discard all affected inventory to prevent health risks. The incident resulted in losses estimated at millions of euros. The attack highlights the vulnerability of critical infrastructure—even climate control systems—to cyber threats, and underscores the real-world consequences when operational technology falls into the wrong hands.
