French Blood Banks Hit by Cyber-Attack: Hackers Raise Temperatures at Cold Stores

France’s national blood service, EFS, has confirmed that hackers accessed control systems at three cold storage facilities and raised temperature and defrosting thresholds to “very high levels.” The attack targeted vital blood products, but alarm systems alerted technicians who intervened before any products were compromised. This incident is the latest in a series of cyber-attacks on refrigerated storage across Europe, raising concerns about the security of critical healthcare infrastructure. The EFS has not attributed the attack to a specific group, but the pattern suggests a deliberate effort to disrupt medical supply chains. The attack highlights the vulnerability of essential services to cyber threats and the need for robust defenses. As investigations continue, blood services across Europe are reviewing their security protocols to prevent similar incidents.
