The incident appears linked to a fresh wave of cyberattacks on supermarket refrigerators across Europe, which forced stores to throw out spoiled food. That wave came just weeks after French supermarkets were first hit by a cyberattack that also hit refrigerators.
French media reports said refrigeration company Coolworld is the supplier to EFS. The company said in a statement that it’s aware of the incident and that it “concerns a component supplied by a third-party provider and not directly controlled by Coolworld.” It said only a “limited number” of its units were affected.
In the attacks on supermarkets, refrigerator defrost settings were manipulated so the coolers reached very high temperatures, mirroring the EFS’s experiences. The blood stored in the affected equipment, which included plasma bags for transfusions, has been “transferred or secured,” the EFS said.
French digital minister Anne Le Hénanff said in the country’s Senate today that the recent attacks on the country’s refrigerators “have directly targeted our economy and our supply chain.”
“I would even go so far as to say that, beyond that, their objective may potentially be to undermine the unity of our country and to create anxiety among the population,” she said.
