Hackers Hijacked French Blood Plasma Freezers, Changing Temperature Settings From −30°C to 110°C

Hackers breached refrigeration systems controlling blood plasma freezers in France, altering temperature settings from minus 30 degrees Celsius to 110 degrees Celsius. The cyberattack targeted cooling service provider Coolworld, which supplies the French Blood Establishment. Staff members successfully intervened before any blood plasma products or medical samples suffered damage. Alarms alerted personnel to the tampering, allowing them to secure the frozen plasma before the equipment reached boiling point levels. This incident forms part of a broader wave of cyberattacks striking cooling infrastructure and blood storage facilities across Europe.
