New Zealand’s ManageMyHealth Patient Portal Data Breach: Cyber Attack on 1.8 Million Users

ManageMyHealth, New Zealand's largest patient portal, detected an unauthorised access affecting an estimated 108,000–126,000 users (6–7% of registered accounts), with a large volume of files potentially containing names, contact details and health records exposed; the operator reports the breach contained, external forensics engaged and notifications to affected users and authorities underway, while a cybercrime group has claimed responsibility and is demanding about USD 60,000 in ransom.
