GoKawiilHackers hijack cold-storage systems at France's blood bank EFS
The French Blood Establishment (EFS) said hackers broke into refrigeration systems at three of its sites on Monday, pushing temperatures and defrost thresholds to dangerously high levels. The intrusion exploited a vulnerability in Coolworld, the third-party refrigeration provider, rather than targeting EFS directly. No blood products were lost; staff caught the anomaly via monitoring systems and moved samples to other facilities before damage occurred.
