Dear Patients,

We are writing to provide an update regarding the recent cyber security incident involving the ManageMyHealth (MMH) portal.

What is the current status?

• MMH has confirmed that a targeted hacking attack occurred on 30 December 2025.
• They have since identified and closed the security gap, and external experts have verified that the system is now secure.
• Forensic investigations suggest that approximately 7% of users nationwide may have had documents accessed.

What does this mean for you?

• MMH has temporarily paused all access to the “Health Documents” section (specialist letters, blood test results) while they finalise their investigation.
• If your data was involved, MMH will contact you directly via email or letter with specific guidance. We will also contact you as soon as we know who has been affected, but at this time we have not yet been informed which of our patients have been affected, if any.
• Using the portal can continue for activities such as 

• • Requesting Repeat Prescriptions: You can continue to order your regular medications as usual for now.
  • Booking Appointments: You can still use the app to book and manage your visits for now.

• If you have any difficulty using the app for scripts or bookings, please email us or call our reception team.

• MMH have confirmed that no logins/passwords were compromised. However, it is always a good idea to reset all passwords regularly and enable 2 factor authentication when available.  Manage My Health users can enable Multi-Factor Authentication (MFA) using a supported authenticator app, providing an additional layer of account security.

  Supported Authenticator Apps
  • Google Authenticator
  • Microsoft Authenticator

  Here is the link with instructions to enable the two-factor authentication (you need to be logged in to access the link).

Our own internal practice systems and data were not affected by this incident and remain secure. We are temporarily not uploading any new records to your app until we have more information.
