Hackers Breach French Blood Bank Freezers and Raise Temperatures

Hackers breached refrigeration maintenance contractor Coolworld and remotely reprogrammed cold storage units at France's national blood agency to 110°C between November 1 and 2.

An on-duty technician noticed the abnormal overnight temperature spike on monitoring systems, allowing emergency technical teams to intervene before permanent damage occurred.

France's Ministry of Health confirmed the breach was contained with zero operational disruption, while officials verified that frozen plasma for transfusions was stored in the affected units.
