A cyber attack targeted the French blood supply coolers, setting the temperature of the cold storage rooms very high.

A cyberattack targeted the French blood supply service's refrigeration supplier, affecting three sites. Attackers raised temperature thresholds in storage units for blood products and biological samples. The EFS's alarm system detected the anomalies, allowing for quick intervention to prevent spoilage. Blood donations and supply remain unaffected. An investigation is underway to determine the attack's execution and impact. This incident coincided with similar attacks in eight European countries, where hackers manipulated refrigeration systems, leading to food waste in stores. A previous attack in October also disrupted over a hundred French supermarkets.
