French blood banks hit by hackers causing storage temperature to rise

A temperature increase was detected at three blood storage sites in France, but no blood products were lost. The French blood bank EFS reported that alarms were triggered quickly, preventing damage. The attack targeted the cooling system supplier, Coolworld, rather than the blood banks themselves. This incident coincided with cyberattacks on supermarket cooling systems across Europe, leading to significant food waste and financial losses for companies like Ahold Delhaize. Investigations are ongoing to determine any connections between the incidents.
