Hackers tried to destroy a blood supply to donors in France and raised the temperature in storage facilities to 110 degrees Celsius. Fortunately, the plasma reserves were saved and the products were not damaged: the technician on duty noticed the increase in temperature, and then the workers moved some of the supplies to other storage facilities. At the same time, hackers attacked supermarket refrigerators in eight European countries. The criminals remotely raised the temperature, causing stores to throw away large amounts of food. Among the chains affected are Carrefour, Delhaize, ICA and LOL.
