Hackers tamper with settings at three French blood product stores

France’s national blood service says hackers altered temperature and defrosting settings at three cold stores holding blood products. Alarm systems enabled technicians to intervene before supplies were compromised, and the incident highlights how cyber-attacks on connected refrigeration could threaten essential services.

The affected stores were run by contractors, and plasma bags and other products were moved elsewhere. The EFS supplies more than 1,900 hospitals and supports over a million patients annually. The attack came amid refrigeration disruptions in supermarkets across almost a dozen European countries; authorities have not identified a motive or culprit, and France’s cybersecurity agency and health ministry have been alerted.
