On December 23, 2025, the ransomware group anubis listed Woodglen Medical Group on its leak site and claimed responsibility for a ransomware attack that resulted in the exfiltration of internal files. The number of individuals whose information may be involved has not been disclosed.

What happened

The incident came to public attention when anubis posted Woodglen Medical Group on its data-leak site. The group claims to have carried out a ransomware operation against the organization and to have removed internal files. No further details on the date of the intrusion, the volume of data taken, or the method of access have been released by either the group or the organization.

Inside anubis

Anubis is a ransomware group that follows a double-extortion model. It typically encrypts systems to disrupt operations and also removes copies of data, which it then threatens to publish unless a ransom is paid. The group maintains a leak site where it lists organizations it claims to have targeted, a tactic used to increase pressure on victims. Public reporting on the group’s prior activity shows repeated use of this approach across multiple sectors.

Woodglen Medical Group and its sector

Woodglen Medical Group operates as a medical practice. Organizations of this type routinely store and process patient records, appointment information, billing details, and internal administrative documents. A breach affecting such an entity is consequential because medical data is retained for long periods and is subject to strict regulatory requirements in most jurisdictions.

What was likely exposed

The only information released states that internal files were exfiltrated. The precise categories of data contained in those files have not been disclosed. While medical practices commonly hold patient identifiers, clinical notes, insurance information, and staff records, the exact contents of the exfiltrated material remain unconfirmed.

What's at stake

Individuals whose records may be involved face the possibility that their personal or medical information could be published or sold. For the organization, the incident creates operational disruption, potential regulatory scrutiny, and the need to manage notification and remediation obligations. The absence of Reported Details on the scale of exposure means the full extent of these consequences is not yet known.

What to do if you're exposed

Anyone who believes their information may have been involved should monitor statements from Woodglen Medical Group and follow any official guidance it issues. Practical first steps include reviewing account statements for unusual activity, enabling multi-factor authentication on important services, and remaining alert for unsolicited contact that references personal or medical details. Readers can also run a free exposure scan of their email address against known breach data to check for prior appearances in public listings.

Publicly posted by anubis — unverified claim, pending independent verification

Breach listings — particularly those originating from ransomware or leak sites — are third-party claims that may be unverified, incomplete, or inaccurate. A listing does not by itself confirm that a breach occurred or that any specific data was exposed. Severity is an automated assessment, not a definitive rating. Verification status is shown where available.

Attributions to threat groups and methods reflect public reporting and, in some cases, unverified claims made by the groups themselves; they may be incomplete or later revised.
