Safepay claims data breach at gruposancristobal.com.mx

The Safepay ransomware group has listed 20 GB of data allegedly belonging to gruposancristobal.com.mx on their leak site. This announcement, made on May 29, 2025, follows a period of alleged unauthorized access to the organization's systems.

Details of the alleged attack

According to the post published by the threat actor known as Safepay, the group claims to have gained access to the systems of gruposancristobal.com.mx on May 14, 2025. This means the attackers claim to have maintained presence within the network for approximately two weeks before the public announcement was made on their leak site.

Ransomware leak sites are platforms used by cybercriminal groups to exert pressure on victims. These sites often host lists of compromised organizations and, in some cases, samples of stolen data to encourage payment. The use of such platforms is a hallmark of modern ransomware operations, serving as a public stage for extortion.

Data involved in the leak

The leak announcement specifies that a total of 20 GB of data has been compromised. While the specific content of the files has not been detailed in the announcement, it is estimated that the volume of data may contain the institution's financial or operational files.

The listing does not provide specific details regarding the exact content of the data shared; however, it is anticipated that the 20 GB of data may include the institution's financial and operational information.

About Grupo San Cristóbal

Grupo San Cristóbal is a financial services organization based in Mexico. The company provides various financial solutions and services to its client base.

Analysis and implications of the threat

The Safepay group is known to operate using a double-extortion strategy and emerged in late 2024. Double extortion is a tactic where attackers not only encrypt an organization's data to disrupt operations but also steal sensitive information beforehand. The threat actors then threaten to leak this stolen data on the internet if the ransom is not paid, thereby targeting the organization's reputation and legal standing in addition to its operational continuity.

Given that the institution operates in the financial services sector, there is a possibility that the leaked data may include customer information or sensitive financial records. This situation could lead to legal obligations for the institution under Mexican data protection regulations. Furthermore, there is a risk that the leaked data could be used for identity theft or targeted phishing attacks.

The group's double-extortion strategy may threaten both the operational continuity and the reputation of the institution. For organizations in the financial sector, such incidents highlight the importance of robust defensive measures. Common defensive steps for organizations include implementing multi-factor authentication, maintaining regular offline backups, conducting regular security audits, and ensuring continuous monitoring of network traffic to detect unauthorized access early.
