French blood banks foil new cyberattack targeting refrigerators
A cyberattack targeted refrigeration monitoring and control systems at three French Blood Establishment sites, prompting cold stores to be programmed to heat to 110C instead of remaining at -30C. The incident raised concern because the stores held donated blood and plasma used for transfusions and medicines, but authorities said supplies and patient care were not affected.
The EFS reported no loss of blood products, and collection and distribution continued uninterrupted. The health ministry said monitoring and alarm systems helped safeguard the supplies, while national cybersecurity officials and other investigators began examining how the attack occurred; no suspected perpetrator was identified. The incident comes amid other suspected cyberattacks affecting refrigeration systems and a French bank.
In short
- Hackers targeted refrigeration systems at three French blood sites.
- Authorities reported no lost supplies or health impact.
- Investigations are under way, with no attacker identified.
Explained simply
The French Blood Establishment, known as EFS, collects and distributes donated blood and plasma for hospitals. Blood products need to be kept at carefully controlled temperatures: some are used in transfusions, while plasma is also used to make medicines.
The affected refrigeration systems monitor and control the temperature of cold stores at EFS sites. Keeping those systems working is important because damaged or overheated supplies may not be usable, and hospitals rely on a steady supply of blood products.
