www.advancedentdenver.com Listed by lynx Ransomware Group: Ransomware Claim — What’s Alleged & What To Do
www.advancedentdenver.com was listed by the Lynx ransomware group on December 16, 2025, with internal files reported as exfiltrated. Individuals should check whether their information was exposed and review guidance from the organization or relevant authorities.
What happened
The only confirmed public record of the event is the listing itself. The group claims that files were removed from the organization during a ransomware operation. No information has been released about when the intrusion occurred, how many records were taken, or whether any data has been published elsewhere. The organization has not issued a statement on the matter, and the total number of individuals affected remains undisclosed.
Who is lynx?
Lynx is a ransomware operation that has appeared in public reporting since 2024. Like other groups in this category, it typically gains access to corporate networks, deploys encryption, and removes copies of files before demanding payment. The group maintains a site where it lists victims and sometimes posts samples of material it says was taken. Any specific claim about www.advancedentdenver.com originates from that listing and has not been independently verified in available records.
www.advancedentdenver.com and its sector
Advanced ENT & Allergy Center operates as a medical practice in Denver that provides allergy testing, sinus care, and related treatments. Organizations of this type routinely collect and store patient identifiers, contact details, insurance information, and clinical notes generated during consultations. A breach at such a provider is consequential because the records it holds are both sensitive and subject to regulatory protections that govern how medical information may be used or disclosed.
The information in question
The listing states that internal files were removed. No inventory of those files or description of their contents has been released. While healthcare providers commonly maintain electronic health records, appointment data, billing information, and staff correspondence, the precise categories of material involved in this case are unconfirmed.
What's at stake
Individuals whose records appear in the exfiltrated material could face risks of identity misuse or unwanted disclosure of health details. For the organization, the incident adds potential regulatory scrutiny and operational costs associated with investigation and notification. Because the scale of the data removal is not public, the full extent of these consequences cannot yet be measured.
What to do if you're exposed
Anyone who has been a patient or employee of the practice should watch account statements and medical correspondence for unusual activity. Changing passwords on patient portals and enabling multi-factor authentication where available are standard first steps. Individuals can also check whether their email address appears in known breach datasets through publicly available exposure scanning tools.

Publicly posted by lynx — 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.
