• Ransomware group: ms13089
• Country: Germany
• Sector: Healthcare
• Announcement date: December 18, 2025

The threat group identified as ms13089 has published a data breach announcement on its leak site, claiming to have targeted uro.com. This announcement, made public on December 18, 2025, involves a claim of unauthorized access to information belonging to the medical institution.

The claimed attack event

According to the announcement posted by the ms13089 group, the organization uro.com has been targeted in a cyberattack. The group has created a specific leak announcement to claim responsibility for the incident. As part of this claim, the group has published a list containing various file names that they allege belong to the institution. This list was made available via the group's dedicated leak site on December 18, 2025.

In the current cyber threat landscape, ransomware groups often utilize leak sites to pressure victims. This tactic is frequently associated with double extortion, where attackers not only encrypt an organization's systems but also steal sensitive data to threaten its public release. By publishing file names, threat actors attempt to demonstrate the legitimacy of their breach and increase the pressure on the victim to meet their demands. In this specific case, the group has provided a list of files, though the total volume of data and the specific ransom demands remain unknown.

Data allegedly involved in the breach

The information released by the ms13089 group includes a screenshot displaying a list of file names. These files are claimed to belong to uro.com and are believed to potentially contain sensitive information. The specific types of data mentioned in the claim include:

• Patient records
• Administrative documents

While the group has provided a list of file names, there is no information available regarding the total size of the stolen data or the exact number of files involved. Furthermore, details concerning the specific nature of the files or the exact content of the administrative and patient records have not been disclosed by the group. Publicly available information regarding the specific methods used by the ms13089 group to conduct this attack is currently limited.

Organization profile

Virginia Urology, which operates under the domain uro.com, is a medical center that has been providing urological healthcare services in the Richmond, Virginia area since 1929. The institution is established as a provider of comprehensive urological care and treatment services to patients within that specific region.

Potential risks and industry implications

This alleged leak, targeting an institution within the healthcare sector, may pose significant risks regarding patient privacy. Because healthcare organizations handle highly sensitive information, the exposure of personal health information could lead to serious legal consequences under the General Data Protection Regulation (GDPR) and other relevant regional regulations. The potential impact of such a breach extends beyond legal compliance, as it can lead to significant reputational damage and cause substantial disruption to the institution's operational processes.

From a security perspective, the exposure of such data creates a high risk for both the institution and its patients. There is a potential for individuals to be subjected to identity theft or targeted phishing attacks, where attackers use stolen personal or medical details to conduct more convincing fraudulent activities. The uncertainty surrounding the ms13089 group, due to the limited public data regarding their motivations and methods, adds to the complexity of the threat. This uncertainty necessitates that organizations consider the risks of secondary extortion or the wider, uncontrolled dissemination of the stolen data.

To mitigate these types of risks, organizations in the healthcare sector typically focus on robust defensive measures. This includes implementing strong access controls, maintaining rigorous encryption standards for data at rest and in transit, and conducting regular security audits. Furthermore, continuous monitoring and rapid incident response capabilities are essential to detect and contain breaches before they escalate into large-scale data exfiltration events. Given the evolving nature of ransomware tactics, maintaining a proactive security posture is a critical component of protecting sensitive patient information and ensuring operational continuity.
