French blood service stops cold-room tampering after supplier cyberattack

Attackers altered refrigeration at three French blood-service sites via a supplier; monitoring stopped any product loss.

France’s blood service, the Établissement Français du Sang (EFS), says a cyberattack on refrigeration supplier Coolworld changed cold-room controls at three sites, including Burgundy and Franche-Comté. Monitoring and alarms caught the changes—settings pushed toward 110°C, from about −30°C according to The Register—and staff moved plasma and other products; EFS says collection and distribution continued with no product loss or health impact. Coolworld said only limited units were hit and, according to BleepingComputer, a third-party component vulnerability was exploited. The case was reported to ANSSI and the health ministry. Outlets link it to a wider European refrigeration wave; Security Affairs cites supermarket attacks in eight countries, while The Record cites 11.
