Osaka General Medical Center had to suspend routine medical services after a ransomware cyberattack shut down the facility’s electronic medical record system.
The centre still performed emergency operations but had to stop providing outpatient services and postponed other surgeries.
Staff members noticed a network server failure on Oct. 31, along with messages sent in English saying “all files have been encrypted.”
Around 1,000 patients were affected by the attack and the disabled electronic medical record system made it nearly impossible to calculate medical treatment fees or check the details of the patient’s medical histories.
The hackers demanded a ransom to be paid in bitcoin cryptocurrency.
