Hospital administrators declared an internal emergency as staff struggled to access patient records and computer systems critical for patient care. Some patients had to be transported to other hospitals to maintain their continuity of care. All the while, attackers held the hospital’s computer systems hostage until a ransom of 40 Bitcoins – approximately US$17,000 – was paid. Only then could the hospital regain use of its files that had been surreptitiously encrypted by malware.
