跟进：法国血液机构冷柜遭网络攻击：设定温度被从零下30度改至110度，值班人员及时发现
法国巴黎——法国周刊《鸭鸣报》11月3日披露，11月1日至2日夜间，黑客攻击了法国血液机构（EFS）的制冷设备供应商 Coolworld，把保存血液制品的冷柜设定温度从约零下30摄氏度改至110摄氏度。勃艮第-弗朗什-孔泰大区的设施在受影响之列。
法国卫生部表示，值班技术人员及时发现温度异常并介入处理，此事没有造成运营后果。EFS最初称受影响的是用于输血健康监测的献血者样本，随后澄清说，用于患者输血的冷冻血浆也在受影响范围内。新鲜冷冻血浆须保存在零下25摄氏度或以下。
需要说明的是，110摄氏度是被写入控制系统的设定值，并不表示冷柜内部或血浆实际达到了这一温度。目前公开报道未确认有血浆被毁、输血受影响或患者受害的情况，受影响设备数量、异常持续时长与攻击者身份均未公布。
这起事件与今年以来欧洲多国超市制冷设备接连遭网络攻击属同一类风险形态：攻击者操纵的是联网制冷设备的控制系统，而非血液机构的信息系统本身。法国网络安全机构此前已就相关制冷控制器被入侵发布过警示。
Hackers Target French Blood Service Freezers: Setpoint Changed From -30C to 110C, Technician Spots It in Time
Paris, France — Hackers attacked Coolworld, a refrigeration supplier to the French Blood Establishment (EFS), on the night of November 1-2 and changed freezer setpoints from about -30 degrees Celsius to 110 degrees, the French weekly Le Canard enchaine reported on November 3. Facilities in the Bourgogne-Franche-Comte region were among those affected.
France's Health Ministry said an on-duty technician detected the abnormal readings in time and intervened, and that the incident caused no operational consequences. The EFS first said the affected material was donor samples retained for transfusion health monitoring, then clarified that frozen plasma intended for patient transfusions was also involved. Fresh frozen plasma must be stored at -25 degrees Celsius or below.
The 110-degree figure is a setpoint entered into the control system; it does not mean freezer interiors or plasma actually reached that temperature. No plasma destruction, disrupted transfusion or patient harm has been publicly confirmed, and the number of affected units, the duration of the disturbance and the attackers' identity have not been disclosed.
The incident resembles the refrigeration attacks that have hit supermarkets across several European countries this year: the target was the control system of connected cooling equipment rather than the blood service's information systems. France's cybersecurity agency had previously alerted operators about compromises of related refrigeration controllers.
