Atlanta Allergy & Asthma. Part 1. Listed by nefilim Ransomware Group: Ransomware Claim — What’s Alleged & What To Do
The Atlanta Allergy & Asthma. Part 1. Listed by nefilim Ransomware Group (reported September 9, 2021) is an unverified claim; the data involved is undisclosed belonging to roughly unknown people. If you have an account with them, your information may now be circulating on the open web and with data brokers. Here’s exactly what happened, how to check if you were affected, and what to do next.
On September 9, 2021, the Atlanta Allergy & Asthma. Part 1. organization appeared on a leak site maintained by the nefilim ransomware group. The listing indicated that internal files had been taken during a ransomware incident, though the number of individuals affected and the precise contents of any data remain undisclosed.
The appearance of a healthcare provider on such a site raises direct questions for patients and staff whose records may have been copied. When medical practices hold personal and clinical information, any confirmed exfiltration can affect privacy, identity verification, and ongoing care coordination.
Inside the incident
Public reporting on the event is limited to the September 2021 listing. No official statement from Atlanta Allergy & Asthma. Part 1. has detailed the date of the intrusion, the method of access, or the volume of material taken. The only confirmed public detail is the group’s claim that internal files were removed.
The group behind it: nefilim
Nefilim is a ransomware operation documented since 2020 that follows a double-extortion pattern: encrypting systems and copying data before demanding payment. The group has listed numerous organizations on its leak site when negotiations failed, publishing samples or directories to pressure victims. Its listings are presented by the group itself and are not independently verified in every case.

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.
