France’s national blood service has said hackers accessed control systems and boosted temperatures at three cold stores stocking vital blood products, in an apparent escalation of recent cyber-attacks on fridges and freezers across Europe.
The French blood service (EFS) said temperature and defrosting thresholds had been raised to “very high levels” in the attack, adding that its alarm systems had allowed technicians to intervene before the products were compromised.
The EFS is France’s public blood transfusion operator, collecting, testing, preparing and distributing products such as blood, plasma and platelets to more than 1,900 hospitals around the country. It supports more than a million patients a year.
