French authorities are investigating a cyberattack that targeted refrigeration equipment at three blood storage sites. The attack attempted to raise temperatures inside the facilities, but security systems detected the changes before any blood products were damaged. The French Blood Establishment confirmed that no plasma or samples were lost and that hospital supplies continued without interruption.
The incident affected three locations used to store plasma. This material is important for blood transfusions and the production of several medicines. Keeping it at the correct temperature is essential because changes in storage conditions can affect its quality and safety.
According to the French Blood Establishment, the attack changed temperature and defrosting settings to extremely high levels. The unusual settings were detected on Monday. The organisation shared details of the incident late on Tuesday, explaining that monitoring systems and alarms quickly identified the problem.
Staff acted quickly to protect the stored products. Some plasma bags and samples were moved to safe locations, while others remained secure after the refrigeration systems were checked. The response prevented the attack from affecting medical supplies.
The blood establishment said there were no reported health consequences. It also confirmed that blood collection and distribution continued as normal. Hospitals and other healthcare services were therefore able to receive the supplies they needed.
The attack targeted a supplier responsible for refrigeration equipment rather than directly attacking the blood establishment’s main systems. This detail has raised questions about the security of companies that provide technology and equipment to essential services.
French cybersecurity authorities and the Health Ministry are investigating the incident. Their work is expected to examine how the attackers accessed the equipment, how the settings were changed and whether other facilities could face similar risks.
The incident comes amid wider concerns about cyberattacks on refrigeration systems. Several supermarkets in European countries recently reported problems after hackers remotely changed the settings of fridges and freezers. Those attacks caused large amounts of food to spoil and created major financial losses.
The latest incident shows that cyber risks can affect more than business operations. Hospitals, blood banks, food suppliers and other essential services depend on connected equipment to protect important products. A successful attack on these systems could create serious problems for public health and daily life.
For now, the French blood storage facilities remain operational. The quick response by staff and monitoring teams helped protect the plasma and maintain normal services. Authorities will continue their investigation as they work to strengthen the security of essential medical infrastructure.
