Hackers tried to turn blood bank fridges into ovens in chilling cyberattack

Hackers attempted to manipulate refrigeration systems at three blood bank sites in France, aiming to raise temperatures to dangerous levels. However, the attack was detected before any blood products were damaged. The French Blood Establishment (EFS) stated that no supplies were lost and no health consequences were identified. The incident exposed a vulnerability: equipment responsible for keeping vital medical products safe can be at risk through suppliers' computer systems.

The affected cold rooms, which typically store plasma at around minus 30°C, had their temperature and defrosting settings changed to extremely high levels. The EFS's monitoring and alarm systems quickly identified the abnormal settings, allowing staff to intervene and secure the products. Hospitals and patients continued to receive blood collections and distribution as usual, with no disruption to supplies.

French authorities are investigating the incident, and the Health Ministry disabled remote access to the affected refrigerators. Similar attacks on supermarket refrigeration systems in Europe have caused significant disruption, with hackers altering settings and causing food to be discarded. The targeting of blood storage facilities highlights the potential consequences of such attacks, as compromised equipment could put medical supplies needed by hospitals at risk.

The incidents also raise questions about the security of internet-connected equipment for remote monitoring and maintenance. For now, the EFS reports that its blood supplies remain safe and its services are operating normally.
