Blood banks are struck by hackers raising storage temperatures – after supermarket freezers hit

Cyberattackers targeted refrigeration controls at three French Blood Establishment sites, raising temperature and defrosting thresholds in cold rooms holding plasma. Alarm systems alerted staff, who secured or transferred the products; no blood products or samples were compromised, and services to hospitals continued.

The incident struck a refrigeration-equipment supplier on Monday and is being investigated by France’s national cybersecurity agency and Health Ministry. It followed attacks on supermarket refrigeration systems in several European countries, including about 40 Delhaize stores in Belgium and Luxembourg, where spoiled food was reported; the article gives no confirmed link between the incidents.
