Melbourne’s Eastern Health will resume elective surgery this week and will gradually reopen specialist clinics and outpatients appointments following the cyber incident that affected its systems on March 16, which has been confirmed as a ransomware attack.

Eastern Health CIO Lachlan Bakewell said there had been no sign of any exfiltration of data and the organisation was now working with industry partners, cybersecurity experts, the Department of Health and Department of Premier and Cabinet to stage a structured return to normal activity.
