France hit by cyberattacks on banks and hospitals
In recent days, France has faced simultaneous cyberattacks striking two unrelated sectors. While financial institutions became prime targets, hackers also compromised blood bank refrigeration units. Among the affected entities was Crédit Mutuel Arkéa, France’s largest banking groups, which disclosed fraudulent transactions following a breach.
The bank confirmed the breach but refused to disclose the exact sum taken, noting only that it is “not of a nature to undermine the Group’s financial strength and soundness.” Nevertheless, blockchain researcher ZachXBT pinpointed Crédit Mutuel Arkéa as the probable victim of a $133 million theft by observing questionable blockchain transactions.
Crédit Mutuel Arkéya challenged the $133 million figure without offering a different total. The thieves utilized a technique to transfer the stolen funds by extracting money from exchange accounts in the form of USDC and USDT, two stablecoins tied to the US dollar.
Cyberattacks on Financial Institutions
These assets were then washed through multiple other cryptocurrencies and exchanges, with a key step involving conversion to Monero, a private cryptocurrency engineered to obscure transaction history. This incident occurs amid the backdrop of a recent $6.3 billion robbery from crypto exchange Binance, which the FBI has linked to North Korean state-backed hackers.
While the Crédit Mutuel Arkéa attack has not been attributed to any specific group or nation-state, the use of privacy coins and cross-exchange layering in both cases reflects the same fundamental approach to converting stolen institutional funds into assets that are difficult for investigators to follow.
Attack on Blood Banks
A second and completely separate attack occurred in France around the same period, striking refrigeration systems at three locations used by France’s national blood service. The intruders accessed the systems via a refrigeration vendor’s controls and altered the temperature and defrost settings, increasing temperatures to points that could have ruined or ruined the blood supplies.
French authorities reported they noticed the changes and acted promptly to prevent any blood products from being lost. No blood supply was ultimately affected by the incident, but the attack’s nature has caused significant alarm, since blood products cannot be stockpiled like financial reserves.

The attack on critical medical infrastructure represents a qualitatively different category of threat from a financial heist, one where the harm is not measured in dollars but in the availability of a life-saving resource. The refrigeration attack comes as a broader trend of hackers targeting non-financial critical infrastructure has accelerated globally.
The US military was probing a suspected cyberattack on commissary freezer systems at military bases, an incident that reportedly thawed large amounts of food. Both cases show how industrial control systems and linked operational technology have become a growing and vulnerable target.
For patients needing transfusions, surgeries, or emergency care, the impact of a successful attack on blood banks could be dire and immediate. The attack on France’s blood service infrastructure, though contained in this case, shows the potentially severe outcomes of such breaches when they succeed.
According to the report, blood banks manage several distinct products derived from whole blood donations, including packed red blood cells, platelets, plasma, and cryoprecipitate, each of which has specific storage temperature requirements to remain viable. Red blood cells must be stored between 2 and 6 degrees Celsius, platelets between 20 and 24 degrees with continuous agitation, and plasma must be kept frozen, typically at or below negative 18 degrees Celsius.
Because of these precise temperature requirements, the refrigeration and freezing infrastructure that blood banks rely on is considered critical medical equipment. Any disruption to that infrastructure, whether from equipment failure, power outages, or deliberate tampering of the kind carried out in France, poses a direct risk to the viability of stored blood products and to the patients who depend on them. The attackers gained access to the refrigeration systems through a contractor’s control systems, which were connected to the internet.
Consequences of Attacks on Critical Infrastructure
The consequences of a successful attack on critical infrastructure, such as blood banks or hospitals, can be severe and immediate. The disruption of blood supplies can have a direct impact on patient care, and the loss of critical medical equipment can be catastrophic.
