• Announcement date: December 14, 2025

The Argentine state-owned utility company, Agua y Saneamientos Argentinos (AySA), has been listed on the leak site of the ransomware group known as safepay. The threat actor claims to have successfully gained access to the organization's infrastructure, marking a potential significant security incident for the utility provider.

The claims made by safepay

According to the announcement made on December 14, 2025, the safepay ransomware group has officially listed AySA on its dedicated leak site. Upon making the listing, the group initiated a ransom countdown, a common tactic used by ransomware operators to exert pressure on their targets. The threat actor claims that they have successfully breached the organization's internal systems and have obtained access to their infrastructure.

Publicly available information regarding the specific operations, methods, or background of the safepay group remains limited. This lack of public intelligence makes it difficult to attribute the attack to a specific known campaign or to understand the full scope of the group's capabilities. It is noted that the group does not appear to utilize an affiliate program, which suggests that these types of attacks may be coordinated directly by the group members themselves rather than through a distributed network of contributors.

Information regarding the alleged data breach

While the group has claimed access to the infrastructure, the announcement remains vague regarding the specifics of the breach. There is no specific detail or sample file provided in the announcement regarding the nature of the data allegedly exfiltrated from the organization's systems. Furthermore, the listing does not provide information regarding the total volume of data or the specific number of files that have been targeted.

The listing names no specific data types that have been compromised.

About Agua y Saneamientos Argentinos

Agua y Saneamientos Argentinos (AySA) is a major entity within the Argentine utility sector. It serves as the country's largest state-owned utility company. The organization is responsible for the essential water supply and sanitation services that support the Buenos Aires region and its surrounding metropolitan areas.

Implications and industry considerations

The targeting of an organization like AySA carries significant implications due to the nature of the services provided. Because the organization manages critical infrastructure, any potential data breach or disruption poses serious risks to operational continuity. When critical services such as water and sanitation are involved, the stability of the infrastructure is paramount to public welfare.

The tactics employed by the safepay group appear to align with the double-extortion model. In this scenario, threat actors do not merely encrypt data to disrupt operations; they also steal sensitive information to use as leverage. This method increases the pressure on an organization, as the threat of leaking data can be used to compel payment even if the organization has backups to restore its systems. In this specific case, the use of double extortion suggests that employee and customer data could be at risk of exposure.

A successful breach of this nature could lead to several secondary consequences. First, the organization may face significant legal obligations under Argentine data protection regulations regarding the handling and protection of sensitive information. Second, the leaked data, if released, could potentially be utilized by malicious actors for identity theft or for launching highly targeted phishing campaigns against the organization's employees or its customer base.

For organizations operating in the energy and utilities sector, maintaining robust cybersecurity postures is essential to mitigate these risks. Standard defensive measures often include implementing strict network segmentation to prevent lateral movement, maintaining comprehensive logging and monitoring to detect unauthorized access, and ensuring that critical operational technology (OT) environments are isolated from standard corporate IT networks. Additionally, regular security awareness training is vital to protect against the phishing attempts that often follow such data breaches.
