An anonymous reader quotes a report from Reuters: The refrigerators at three regional blood banks in France were hit by a cyberattack overnight between Sunday and Monday, at the same time hackers struck supermarkets from Sweden to Belgium. "Several regional facilities of the French Blood Establishment (EFS) were affected by a cybersecurity incident that impacted certain cold storage room monitoring and control systems," the health ministry said in a statement. The incident had no impact on blood supplies, EFS spokesperson Charley Dubois said. "We have staff round the clock since blood can be needed at any time. They were warned about the problems by alerts and moved the blood to other refrigerators that were not connected," she said.

The attack followed a similar incident in France last month when police said hackers seized control of cooling units at hundreds of supermarkets, causing fires and food losses.
