Appointment systems, pathology labs, x-rays and even CT scanners were infected - putting not just data but patients lives at risk, and on every screen a ** - some may even say polite - message appeared. *Ooops, your files h*e been encrypted!*But what followed was far from civilised. It was very clear that all the data on an infected machine was now scrambled and only the hackers could unscramble it. For a price - and with an extra twist - after a few days the ransom money doubled, and if nothing was paid within a week, the hackers threatened to destroy all the data - forever.综艺 BBC地平线：网络攻击-国家医疗服务系统瘫痪之日 豆瓣评分（8.0）
