French blood cold-storage attack stopped; no products lost

Attackers hit French blood cold storage and European supermarket refrigeration; staff and monitors prevented product loss as CISA warned operators.

France’s national blood service suffered a cyberattack on cold storage at three sites that tried to raise refrigeration temperatures to 110C, targeting plasma products, SecurityWeek reports. Monitoring systems and staff stopped the change before any blood products or samples were compromised, with no health consequences, and French authorities are investigating. The incident fits wider European refrigeration attacks, including at least 17 supermarket businesses in the Netherlands, according to Malwarebytes. Affected systems were reachable over unsecured connections using default passwords. Danfoss advised disconnecting systems from the internet, and CISA and partners urged firmware patching and network isolation. SecurityWeek identifies a Coolworld supplier component in the blood-site attack.
