French blood banks targeted by refrigerator cyberattack

A cyberattack targeted refrigeration controls at three French blood and plasma storage sites, attempting to raise temperatures high enough to spoil their contents. The incident matters because blood products are vital medical supplies, but monitoring systems detected the changes and staff secured the products before any were lost.

The French Blood Establishment said no blood products were lost, no health consequences were identified and distribution continued without interruption. A report said temperatures were set to reach 110°C instead of the usual -30°C; France’s cybersecurity agency and Health Ministry are investigating, while the refrigeration supplier attributed the vulnerability to a third-party component. Related attacks disrupted supermarket refrigeration across several European countries, and Dutch retailer Ahold Delhaize estimated an earlier attack could cut quarterly sales by up to €250 million.
