Numerous hospitals were victims to last week’s (aka NotPetya) ransomware attack. But one hospital—Princeton Community Hospital in West Virginia–has admitted that it is going to replace its entire computer network after Petya froze its electronic medical record making it unable to treat patients. They could not restore the electronic medical record, could not pay the ransom (because the link to pay did not work) so they resorted to documenting patient encounters on paper.

Hospital officials estimate that it will be able to replace the system by the end of this week, which is remarkable.
