adifse.com.ar Listed by safepay Ransomware Group: Ransomware Claim — What’s Alleged & What To Do

On January 9, 2026, the ransomware group safepay listed adifse.com.ar on its leak site, stating that internal files had been taken from the Argentine state-owned railway infrastructure operator. Public records show no independent confirmation of the volume of data or the circumstances of the access at the time of reporting, and the number of individuals potentially affected remains unknown.

Ransomware operations that combine encryption with data exfiltration continue to affect public-sector entities that manage essential services. When such an incident is disclosed only through a threat actor’s site, the available information is limited to the group’s assertions until the victim or investigators release further details.

What happened

The only public indication of the incident is the listing published by safepay on 9 January 2026. The entry states that internal files were exfiltrated during a ransomware attack against adifse.com.ar. No additional technical details, such as the date of the intrusion, the method of initial access, or the quantity of data involved, have been disclosed in the available facts.

Inside safepay

Safepay is a ransomware operation that publicly claims responsibility for intrusions by posting victim names and sample files on a dedicated leak site. The group’s pattern, documented in multiple prior incidents, involves encrypting systems and removing copies of data before demanding payment. Listings on the site represent the group’s own statements and are not independently verified unless corroborated by the affected organisation or law-enforcement findings.

About adifse.com.ar

ADIFSE, formally the Administración de Infraestructuras Ferroviarias Sociedad del Estado, is the Argentine state enterprise responsible for the maintenance and development of the national railway infrastructure. Organisations of this type routinely hold operational records, engineering documentation, supplier contracts, and internal communications related to rail networks. A breach at such an entity can therefore involve both administrative data and information tied to physical infrastructure.

What was likely exposed

The listing refers only to “internal files exfiltrated in ransomware attack.” No inventory of specific file types or data categories has been released. Entities that manage railway infrastructure typically store employee records, maintenance logs, procurement documents, and network diagrams; however, whether any of these categories were among the files taken in this case is unconfirmed.

Why it matters

Railway infrastructure data can contain details whose exposure may assist further targeting of operational systems or supply chains. For individuals whose information appears in internal files, the main concerns are potential misuse of personal identifiers or contact details. For the organisation, the incident adds to the operational burden of incident response and any subsequent regulatory or contractual obligations.
