What happened
The incident became known when Safepay added aysa.com.ar to its leak-site listing on 14 December 2025.

No independent confirmation of the claim or further technical details have been made public. The number of people affected and the precise date of the underlying attack are undisclosed.
Inside safepay
Safepay operates as a ransomware-as-a-service group that has appeared in public reporting over the past several years. Groups of this type commonly use double-extortion methods, encrypting victim systems while also copying data and threatening its release. They maintain dedicated leak sites to list organisations that have not met their demands. The listing of aysa.com.ar constitutes the group’s claim; no additional statements from Safepay about this specific case have been verified beyond the site entry itself.
About aysa.com.ar
AYSA, formally known as Agua y Saneamientos Argentinos Sociedad Anónima, is Argentina’s largest state-owned water and sanitation utility. Entities in this sector manage large-scale public infrastructure for water supply and wastewater treatment. They routinely collect and store operational records, customer account information and regulatory documentation required to deliver essential services across a wide geographic area.
What was likely exposed
The only detail provided is that internal files were allegedly exfiltrated. The specific categories of data contained in those files have not been disclosed. Organisations of this kind typically hold billing records, infrastructure schematics, maintenance logs and limited personal information linked to service accounts, yet the exact contents involved in this incident remain unconfirmed.
The real-world impact
Release of internal files from a water and sanitation utility can create operational and administrative complications for the organisation, including potential regulatory review and the cost of investigation and system restoration. For individuals, any personal data present in the files carries the usual risks associated with exposure, such as attempts at account misuse or identity-related fraud. The absence of confirmed data types makes it difficult to assess the scale of personal impact at this stage.
If your data was in this claimed breach
People who hold accounts with AYSA should watch for unusual activity on linked services and update passwords where reuse may have occurred. Checking whether an email address appears in known public breach data through a free exposure scan offers one practical way to identify whether information has already surfaced in other listings.

Publicly posted by safepay — 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.
