ManageMyHealth - New Zealand Listed by Kazu Ransomware Group

On December 30, 2025, New Zealand healthcare platform ManageMyHealth appeared on the leak site of the kazu ransomware group. The company, which provides patients with online access to medical records, test results, prescriptions, and appointment scheduling, is claimed to have had internal files exfiltrated during a ransomware attack. While the exact number of affected individuals remains unknown, anyone who has used the service to store or view personal health information could have their data at risk.

Already exposed?

You can’t unleak data. You can take away what it’s worth.

A leaked record is where it starts, not where it ends. What turns it into your front door is the look-up sites publishing your address beside your name — and those are what an AI reads when somebody asks about you. The free scan shows you both. We write to 580 companies.

What Public Reporting Shows

Public reporting indicates that kazu listed ManageMyHealth on its data leak portal on December 30, 2025. The exposed material consists of internal files exfiltrated during a ransomware incident. ManageMyHealth has not yet issued a public statement confirming the breach or detailing the precise volume or sensitivity of the stolen data. Available reporting describes the incident as a classic ransomware operation involving both encryption and data theft for extortion purposes.

Why This Matters for You and Your Family

Health records are among the most sensitive types of personal information. If your ManageMyHealth account contains test results, prescription details, medical history, or communications with doctors, that information could now be in the hands of criminals. For you and your family this means potential exposure of conditions, treatments, addresses, phone numbers, and dates of birth. Such details can be used for identity theft, insurance fraud, or targeted scams that feel deeply personal because attackers know real medical facts about you.

Medical data rarely loses its value to criminals. Unlike a credit card that can be cancelled, your health history stays relevant for years. Families with children who have used the platform for vaccination records or specialist referrals face the same risk — one breach can affect every household member whose information was stored under a shared login or address.

Unverified claim — what this report is

This page documents a public listing on a ransomware/extortion group’s leak site, tracked via public threat-intelligence sources. A listing is the attacker’s claim. GalaxyWarden aggregates and reports such claims; we have not independently verified that a breach occurred, what data (if any) was taken, or the accuracy of anything the group asserts, and the named organisation has not necessarily confirmed the incident. Sections above describe what the listing shows and the group’s documented history — not verified findings about the named organisation. If you represent this organisation and believe anything here is inaccurate, tell us and we’ll review it promptly.

Editorial & sourcing policy

GalaxyWarden is a breach-monitoring service and news aggregator. We do not exfiltrate, host, purchase, or redistribute stolen data. Breach information is compiled from publicly accessible sources and threat-intelligence platforms, and is reported as claims attributed to their source. We promptly correct or remove material shown to be inaccurate — see our content & takedown policy or write to support@galaxywarden.com.
