felixvet.com Listed by lockbit5 Ransomware Group: Ransomware Claim — What’s Alleged & What To Do

On 30 October 2025, the veterinary practice operating as felixvet.com appeared on a listing associated with the lockbit5 ransomware group. Public reporting indicates that internal files were claimed to have been taken during a ransomware attack, though the number of people affected remains unknown and further technical details have not been released. For clients, staff and anyone who has shared personal or animal-related information with the clinic, the practical concern is straightforward: data that was meant to stay inside the organisation may now sit outside its control.

Because the listing itself is an unverified claim by the group, the full scope of what occurred is still limited. What is known is enough to warrant attention from those who have used the service, particularly given the kinds of records a veterinary practice typically maintains.

What happened

According to the available record, felixvet.com was listed by the lockbit5 ransomware group on 30 October 2025. The report states that internal files were exfiltrated in a ransomware attack. No confirmed figure for the number of people affected has been published, and the precise method of intrusion, the volume of data taken, or any ransom demand have not been disclosed in the public summary. The organisation is identified as a veterinary cabinet known as “Феникс Вет,” described as providing accessible services and a full range of vaccines. Beyond that short characterisation and the claim of file exfiltration, public detail on the incident remains limited.

Inside lockbit5

Lockbit5 refers to the latest iteration of the LockBit ransomware operation, a well-documented ransomware-as-a-service group that has been active for several years. The group typically gains access to networks, encrypts systems, and steals data before posting victims on a dedicated leak site if payment is not made. This double-extortion model is intended to increase pressure by threatening public release of the stolen material. LockBit has previously claimed responsibility for attacks across many sectors and countries; its operators recruit affiliates who carry out the intrusions while the core group provides the ransomware tools and leak infrastructure. Listings on its site are claims made by the group and do not by themselves constitute independent confirmation that every detail is accurate or that data has already been published. In this case, the facts state only that felixvet.com was listed and that internal files were described as exfiltrated; no further statements attributed specifically to lockbit5 about this victim appear in the provided record.

felixvet.com and its sector

felixvet.com operates as a veterinary clinic offering routine and accessible animal-health services, including vaccinations. Veterinary practices of this kind sit at the intersection of healthcare and small-business operations. They routinely handle client contact details, pet medical histories, appointment records, billing information and sometimes payment-card data. In many jurisdictions they also store notes that can include home addresses, phone numbers and, less commonly, limited personal health information about owners when it is relevant to animal care. A breach involving such an organisation is consequential because the data is both personal and operational: it can identify individuals, reveal patterns of care, and expose internal business documents that were never intended for public view. Even when the exact contents of a theft remain unconfirmed, the sector’s normal data holdings make any successful ransomware incident a matter of legitimate concern for clients and staff.

The information in question

The facts name the exposed material only as “internal files exfiltrated in ransomware attack.” No inventory of specific data types—such as names, addresses, medical records or financial details—has been publicly confirmed. Organisations of this kind typically hold client contact information, animal medical histories, vaccination records, appointment logs, invoices and internal administrative documents. Whether any of those categories were among the files taken in this incident is unconfirmed. Readers should therefore treat the precise contents as unknown until the organisation or independent investigators provide further clarity. The claim of exfiltration itself comes from the ransomware group’s listing and has not been independently verified in the available reporting.

What's at stake

For individuals whose information may have been involved, the concrete risks include unwanted contact, phishing attempts that use accurate personal or pet details to appear legitimate, and the longer-term possibility of identity-related misuse if contact or payment data were present. Pet medical histories, while less sensitive than human health records, can still reveal household patterns and be used to craft convincing social-engineering messages. For the clinic, the stakes include operational disruption from any encryption of systems, potential regulatory obligations to notify affected parties, and the need to restore trust with clients who rely on the practice for ongoing animal care. Because the number of people affected is unknown and the exact data types remain undisclosed, the scale of these risks cannot yet be quantified; the prudent approach is to assume that any information previously shared with the clinic could be in play until clearer information emerges.

Were you affected?

If you have been a client or employee of felixvet.com, treat the possibility of exposure seriously even while details remain limited. Change any passwords you may have reused with the clinic’s systems, enable multi-factor authentication wherever available, and watch for unexpected emails or messages that reference your pet or recent visits. Monitor financial statements if you have paid the practice by card. You can also run a free exposure scan of your email address to check whether that address has already appeared in known breach data sets. Stay alert for any official notification from the clinic itself, and avoid clicking links in unsolicited messages that claim to relate to this incident.
