MyVete listed on kazu ransomware leak site

• Ransomware group: kazu
• Country: Spain
• Sector: Professional Services
• Announcement date: January 12, 2026

The veterinary software platform MyVete has been listed in a leak announcement allegedly conducted by the threat group kazu. This development follows a pattern common in modern cyberattacks where threat actors target service providers to gain access to a wide array of downstream clients.

The claimed attack and ransom demand

The threat group known as kazu published a leak announcement on January 12, 2026, claiming to have compromised data belonging to MyVete. According to the announcement, the group has exfiltrated 30 GB of data from the institution's software platform, which is used to manage various operational and administrative processes. In exchange for not publishing the stolen information, the group is demanding a ransom of $100,000.

This incident highlights the mechanics of double extortion, a tactic frequently employed by ransomware groups. In such scenarios, attackers do not merely encrypt an organization's systems to disrupt operations; they also steal sensitive data to use as leverage. By threatening to leak the information on a public leak site, the attackers aim to pressure the victim into paying the ransom to avoid reputational damage and legal consequences.

Details of the alleged data breach

Regarding the specific content of the allegedly leaked data, there is no detailed information available at this time. The group has not provided any screenshots or specific file lists to verify the nature of the stolen information. Consequently, the exact scope of the breach remains unconfirmed beyond the volume of data mentioned in the announcement.

Potential risks and implications

This incident suggests that patient records and operational data of veterinary clinics may be at risk. The alleged leak could pose secondary risks such as identity theft or fraud for the veterinarians and pet owners who are customers of the institution. Furthermore, considering the billing and payment tools offered by the platform, the possibility of financial data being compromised should be evaluated.

About MyVete

MyVete is a management software platform designed for veterinary clinics and animal hospitals. The platform digitizes various operational processes, including patient records, appointment management, billing, and inventory tracking. By helping veterinarians track medical histories and send vaccination reminders, the software aims to reduce administrative workloads and allow professionals to focus more on patient care.

Analysis and industry considerations

As the institution is based in Spain, legal processes regarding data protection obligations under the General Data Protection Regulation (GDPR) may be triggered due to the nature of the services provided. Organizations operating in the professional services sector, particularly those handling sensitive client and patient records, must remain vigilant against such threats.

While public information about the kazu group is limited, this event underscores the importance of robust defensive measures. Organizations in this sector can benefit from implementing comprehensive security frameworks, such as multi-factor authentication, regular data backups, and strict access controls. Monitoring for unauthorized data exfiltration and maintaining a clear incident response plan are also critical steps for mitigating the impact of potential breaches. The potential compromise of financial and medical-related data necessitates a thorough investigation by the affected parties to ensure compliance and protect their stakeholders.
