French authorities have reported a cyberattack on several blood banks that attempted to raise temperatures to dangerous levels. The attack was caught before any damage occurred to blood products or samples. The French Blood Establishment said on Tuesday that temperature thresholds were raised on Monday at three cold-storage sites for plasma. No health consequences have been identified, and no blood products were lost. The incident follows similar attacks on supermarkets in Europe, leading to spoiled food worth millions. France’s national cybersecurity agency and the Health Ministry are investigating the incident.
