A Kentucky hospital is operating in an internal state of emergency following an attack by cybercriminals on its computer network, Krebs on Security reported.
Methodist Hospital, based in Henderson, Kentucky, is the victim of a ransomware attack in which hackers infiltrated its computer network, encrypted files and are now holding the data hostage, Krebs reported Tuesday.
The hospital has not responded to CNBC's requests for comment.
The criminals reportedly used new strain of malware known as Locky to encrypt important files. The malware spread from the initial infected machine to the entire internal network and several other systems, the hospital's information systems director, Jamie Reid, told Krebs.
