Its objective is to strengthen the health system in a federal and equitable manner, ensuring access to quality health services for the population. Since September 30, 2024, the Minister of Health is Mario Lugones, who assumed the position following the departure of Mario Russo. The ministry is also responsible for epidemiology, vaccination campaigns, and border health control, among other functions - The data include high sansitive informations for more then 2 mill
— from Nova’s own leak-site posting. This is the group’s claim, quoted verbatim; it is not GalaxyWarden’s reporting and has not been independently verified.

What Public Reporting Shows

Public reporting indicates the Ministry of Health of Argentina suffered a ransomware intrusion. The nova group posted evidence of the breach on its dark-web leak site, stating that exfiltration occurred and that the stolen data includes sensitive records affecting over two million individuals. Available details describe the exposed material as internal files rather than a single structured database. No exact date of initial compromise has been publicly confirmed, though the listing appeared on 12 October 2025. The Argentine government has not yet released an official statement detailing the scope or timeline.

More than 2 million people are potentially affected. The records are understood to contain personal and health-related data collected in the course of the ministry’s responsibilities for epidemiology, vaccination programs, border health control and public health policy.

Why This Matters for You and Your Family

When a national health ministry loses control of sensitive personal records, the consequences reach ordinary citizens and their families. Health data can reveal chronic conditions, vaccination history, family medical details, and in some cases addresses or national identification numbers. Once this information is in criminal hands, it can be used for identity theft, insurance fraud, blackmail, or sold on underground markets. If you or any member of your family has received medical care through Argentina’s public health system, your information may now be exposed. The breach affects not only those directly listed but anyone whose records were stored in the compromised systems.

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.
