Hackers breached the French blood supply system and raised the temperature of the refrigerators

Hackers accessed the control systems of three blood storage facilities in France, raising temperatures dangerously high. The French Blood Establishment (EFS) reported that their alarm systems allowed for timely intervention, preventing damage to blood supplies. The attack targeted storage operated by contractors, not EFS directly. This incident coincided with temperature spikes in supermarket refrigeration across Europe, causing significant food losses. EFS has notified national cybersecurity and health authorities and enhanced monitoring of their equipment. Similar attacks were reported in Italy, Germany, Romania, and the UK following incidents in several other European countries.
