DUNMORE Listed by conti Ransomware Group: Ransomware Claim — What’s Alleged & What To Do
The DUNMORE Listed by conti Ransomware Group (reported November 28, 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.
Breaking down the breach
The only confirmed public detail is the listing itself on Conti’s leak site on 28 November 2021. No information has been released about the date of the underlying intrusion, the method of initial access, the volume of data taken, or whether encryption occurred alongside exfiltration. The organisation has not issued a statement confirming or denying the claims.
Who is conti?
Conti is a ransomware group that has conducted numerous operations since at least 2020. Its standard approach combines encryption of systems with the theft of data, followed by threats to publish the material on a dedicated leak site if a ransom demand is not met. The group has appeared in public reporting on attacks against entities in multiple countries and sectors.
About DUNMORE
DUNMORE is the organisation named in the listing. Entities of this type routinely store operational records, internal communications, and business documentation. A successful intrusion that results in data exfiltration can therefore expose material that is not intended for public release, regardless of whether customer records are involved.
The information in question
The listing refers only to “internal files exfiltrated in ransomware attack.” No further description of file types, record categories, or data volume has been provided. It is therefore not possible to state with certainty what specific information may have been taken.
The real-world impact
Where internal files are exposed, affected organisations may face operational disruption, competitive disadvantage, or regulatory scrutiny depending on the nature of the material. Individuals whose information appears in those files could encounter risks such as targeted fraud or misuse of personal details, though the scale of any such exposure remains unknown in this case.
If your data was in this claimed breach
Individuals concerned about possible exposure should begin with basic account hygiene and ongoing monitoring. A free exposure scan of an email address against known breach data can provide an initial indication of whether information has appeared in public listings.
- Change passwords for any accounts that may be referenced in internal records and enable multi-factor authentication where available.
- Review bank and credit statements for unusual activity over the coming months.
- Place fraud alerts with credit bureaus if financial identifiers could be present in the material.
- Run a free exposure scan of your email address to check for appearances in known breach data.

Publicly posted by conti — 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.
