Cyberattack targets French blood bank refrigeration systems, but no products are lost

A cyberattack targeted refrigeration equipment linked to three cold-storage sites used by the French Blood Establishment, according to officials in France. The incident affected systems used to store plasma, but the organisation said no blood products or samples were compromised. Operations for blood collection and distribution continued without interruption.

The establishment said temperature and defrosting thresholds were raised to extremely high levels on Monday at the three sites. It said monitoring and alarm systems detected the anomalies quickly, allowing staff to respond before any damage was done. The affected products were bags of plasma intended for transfusions and plasma used to manufacture medicines, which were either transferred or secured.

Officials said no health consequences had been identified and no blood products were lost. France's national cybersecurity agency and the Health Ministry are investigating the incident. The attack hit a supplier of refrigeration equipment rather than the blood establishment directly, according to the statement.

The case highlights the vulnerability of health infrastructure to cyberattacks that can affect physical systems as well as data. Cold-chain equipment is essential for preserving blood products, and any disruption can create risks for hospitals and other healthcare services. Even when no material loss occurs, such incidents can force rapid operational checks and contingency measures.

The incident also comes amid reports this week of supermarket refrigeration systems being remotely taken over in several European countries, leading to spoiled food and financial losses. While the French case did not result in losses, it adds to concern about attacks on connected equipment used in essential supply chains. The focus now is on how the supplier was compromised and whether similar systems elsewhere may be exposed.

Authorities have not said who was behind the attack or whether it was part of a wider campaign. It is also not clear whether the intrusion was limited to the refrigeration supplier or whether any other systems were affected. Investigators are expected to examine the technical route used and whether additional safeguards are needed at other storage sites.
