National Health Insurance Management Authority Listed by nova Ransomware Group: Ransomware Claim — What’s Alleged & What To Do
The National Health Insurance Management Authority was listed by the nova ransomware group on December 05, 2025, following the exfiltration of internal files; the date the intrusion actually occurred has not been established. Individuals who may have records with the Authority should check for any official notifications and review their accounts for signs of misuse.
Inside the incident
The only confirmed information is the group’s listing of the authority and its assertion that internal files were taken. No date of the intrusion, no description of the initial access method, and no volume of data have been disclosed. The organisation has not issued a public statement confirming or denying the claims.
Inside nova
Nova is a ransomware group that maintains a public leak site where it lists organisations it claims to have compromised. The group’s typical pattern involves encrypting systems and threatening to publish stolen material if a ransom is not paid. Its listings are presented by the group itself and are not independently verified at the time they appear.
About National Health Insurance Management Authority
The National Health Insurance Management Authority operates the National Health Insurance Scheme, which provides access to healthcare services, medicines and medical equipment for enrolled individuals and families. The scheme manages contributions, benefit packages and employer registrations, placing it at the centre of a country’s health-financing system.
What data was at risk
The listing refers only to “internal files.” The precise categories of information contained in those files have not been disclosed. Organisations of this type routinely hold patient identifiers, medical records, contribution histories and employer data, but whether any of those categories were among the exfiltrated material remains unconfirmed.
What's at stake
Exposure of internal files from a national health insurer can affect the privacy of patients and the administrative records of employers. Individuals may face risks of identity misuse or unwanted disclosure of health information, while the organisation must address potential regulatory obligations and operational recovery. The absence of confirmed data categories makes it difficult to assess the scale of these risks at present.

Publicly posted by nova — unverified claim, pending independent verification
Breach listings — particularly those originating from ransomware or leak sites — are third-party claims that may be unverified, incomplete, or inaccurate. A listing does not by itself confirm that a breach occurred or that any specific data was exposed. Severity is an automated assessment, not a definitive rating. Verification status is shown where available.
Attributions to threat groups and methods reflect public reporting and, in some cases, unverified claims made by the groups themselves; they may be incomplete or later revised.
