Anatomic Clinical Laboratory Associates Listed by insomnia Ransomware Group: Ransomware Claim — What’s Alleged & What To Do
Anatomic Clinical Laboratory Associates was listed by the insomnia ransomware group on November 25, 2025, after internal files were exfiltrated in a ransomware attack. An undisclosed number of people may have been affected; anyone who has interacted with the laboratory should check for breach notices and consider protective steps such as monitoring accounts and changing passwords.
What happened
The only confirmed public information is the November 25, 2025 listing by the insomnia group. The entry asserts that files were removed from Anatomic Clinical Laboratory Associates systems. No additional data on the timing of the intrusion, the volume of material taken, or the method of access has been made public.
Inside insomnia
Insomnia is a ransomware operation that maintains a public leak site to list organizations it claims to have compromised. The group follows a pattern seen with other ransomware actors: it seeks encryption of systems followed by exfiltration of data, then uses the site to pressure victims. Listings on the site represent the group’s assertions rather than independently verified events.
About Anatomic Clinical Laboratory Associates
Anatomic Clinical Laboratory Associates is a physician-owned pathology group based in Nashville that provides diagnostic services to clinicians in Middle Tennessee. Organizations of this type process tissue samples, cytology, and other laboratory tests, generating reports that contain clinical findings and patient identifiers. A disruption or exposure at such a facility can affect diagnostic timelines for referring physicians and the patients they serve.
What was likely exposed
The listing refers only to “internal files.” No inventory of specific record types or data fields has been released. Pathology laboratories routinely create and store records that include patient demographics, test orders, results, and communications with ordering providers. The precise contents of any exfiltrated material remain unconfirmed.
The real-world impact
Individuals whose records may be involved face the standard risks associated with exposure of medical and identifying information, such as potential misuse for identity-related activity or unwanted contact. For the organization, the incident adds the tasks of verifying the scope of access, meeting regulatory notification obligations, and restoring normal laboratory operations. No public statements have addressed whether patient care was interrupted.

Publicly posted by insomnia — 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.
