Cyberattack on blood refrigerators. The temperature was set to 110 degrees

Coolworld, a service provider for EFS, experienced a cyberattack on November 1-2, targeting medical refrigeration units. The attack raised temperatures in blood storage facilities, but operational consequences were avoided as the situation was detected promptly. EFS reported that a technician noticed the temperature increase and measures were taken to secure the equipment. This incident follows a similar attack in mid-October affecting supermarkets in France, although no connection has been established between the two. Cyberattacks on refrigeration systems have also been reported in several European countries, including Poland, where no material damage occurred due to prompt action.
