## Key Points

- EFS confirmed a cyberattack on November 2 on monitoring systems at three donor blood storage facilities
- According to Le Canard Enchaine, the temperature in the refrigerators was raised from −30 to 110 °C
- French authorities state that no damage to blood products was recorded thanks to alert systems
- The incident is part of a series of attacks on refrigeration infrastructure in eight European countries

On November 4, French authorities officially announced a cyberattack targeting refrigerators used to store donor blood. The National Blood Service (EFS) confirmed that a cybersecurity incident occurred on November 2 at its blood storage service provider, affecting monitoring and control systems at three facilities. According to the French weekly Le Canard Enchaine, intruders interfered with the operation of refrigeration units holding blood samples and plasma bags used for transfusions and drug manufacturing, raising the temperature from −30 to 110 degrees Celsius.

### Authorities: Blood Products Unaffected

Despite the severity of the incident, EFS stated that no damage to blood products was recorded. The office of French Health Minister Stéphanie Rist emphasized that the warning and monitoring systems installed at the facilities operated normally and ensured the safety of the stored products. French authorities are currently investigating the cyberattack in an attempt to determine the source of the attack and the scale of the infrastructure breach.

### Part of a Series of Attacks on European Refrigeration Infrastructure

The incident involving French blood banks is the latest in a troubling string of hacking episodes recorded in Europe over recent weeks. On November 2, cyberattacks forced store chains in eight European countries to destroy significant volumes of food products due to hacker interference with refrigeration systems. A similar wave of attacks three weeks earlier affected dozens of supermarkets in France, pointing to a systemic threat to the continent's logistics and refrigeration infrastructure.

### Context: Vulnerability of Critical Infrastructure

Cybersecurity specialists note that the shift from attacks on retail outlets to healthcare facilities indicates an escalation in threat levels. Refrigerators containing donor blood represent critical infrastructure: their compromise can entail not only economic losses but also a direct threat to the lives of patients awaiting transfusions. The French case demonstrates that even with monitoring and warning systems in place, intruders are capable of temporarily disrupting temperature regimes, creating risks for biomaterials.

### What's Next

French authorities have not disclosed details of the investigation, but results are expected to be announced in the coming days. EFS continues to operate normally, and the blood storage service provider is conducting an internal audit of its security systems. Experts predict that the incident will accelerate discussions on the need to strengthen cybersecurity for medical and logistics facilities in Europe, especially amid growing activity in targeted attacks on critical infrastructure.
