French blood banks hacked in latest cyber-attack on Europe

Temperature and defrosting thresholds raised to ‘very high levels’ at three cold stores stocking vital blood products

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.
