Hackers broke into the refrigerators of the French blood service and raised the temperature in them to 110 degrees. According to the newspaper Le Parisien, as a result of a cyber attack, the temperature in the cells, where blood samples must be stored at minus 30 degrees, rose to 110 degrees Celsius. The event affected several regional units. The attack happened on November 2 and affected the systems of Coolworld, which supplies cooling equipment for the French Blood Service (EFS).
