Mid South Pulmonary & Sleep Specialists Listed by anubis Ransomware Group: Ransomware Claim — What’s Alleged & What To Do
Mid South Pulmonary & Sleep Specialists was listed by the anubis ransomware group on November 28, 2025, after internal files were exfiltrated in a ransomware attack. Individuals who received services from the practice should review any notifications and consider steps such as monitoring accounts or placing fraud alerts.
Breaking down the breach
The available information is limited to the group’s listing of the organization. It reports that files were removed from the network in connection with a ransomware operation. No details have been released on the date of the intrusion, the volume of data taken, the encryption status of systems, or any ransom demand. Public records do not show confirmation from the organization itself or from regulators at the time of reporting.
Inside anubis
Anubis is a ransomware operation that follows the common pattern of encrypting victim systems and removing copies of files before demanding payment. When organizations do not meet the demanded terms, the group places their names on a publicly accessible leak site. The listing for Mid South Pulmonary & Sleep Specialists follows this established sequence, though the group’s statements about any specific incident remain unverified claims until corroborated by the victim or by independent investigation.
About Mid South Pulmonary & Sleep Specialists
Mid South Pulmonary & Sleep Specialists provides medical care focused on respiratory and sleep-related conditions. Organizations of this type routinely collect and store patient identifiers, clinical notes, diagnostic results, insurance information, and appointment records. A breach at such a practice therefore touches data that is both personal and medically sensitive, even when the precise contents of any exfiltrated files remain unknown.
What was likely exposed
The listing refers only to “internal files” taken in a ransomware attack and labels the event a patient data breach. No inventory of file types or data fields has been published. Medical practices of this kind commonly hold names, dates of birth, addresses, Social Security numbers, insurance details, and clinical documentation. Whether any or all of these categories were among the files removed is not confirmed by the facts currently available.
What's at stake
Individuals whose information appears in the exfiltrated files face the possibility that their data could be used for identity theft, insurance fraud, or targeted scams. The organization may face regulatory review, notification obligations, and operational costs associated with restoring systems and responding to the incident. Because the scale of exposure is still unknown, the full extent of these consequences cannot yet be measured.
If your data was in this claimed breach

Place a fraud alert or credit freeze with the major credit bureaus if personal identifiers were involved. Review medical and insurance statements for unusual activity.

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.
