deloitte.com Listed by dispossessor Ransomware Group: Ransomware Claim — What’s Alleged & What To Do
The deloitte.com Listed by dispossessor Ransomware Group (reported September 6, 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.
Inside the incident
The incident was first noted publicly on September 6, 2021, when deloitte.com appeared on a listing associated with the dispossessor group. The only detail provided in the available record is that internal files were allegedly exfiltrated in a ransomware attack. No information has been released on the date of the intrusion, the method used to gain access, the volume of data involved, or whether any ransom demand was made or met.
The group behind it: dispossessor
The listing attributes the activity to the dispossessor ransomware group. The group claims responsibility for the exfiltration of internal files from the listed organisation. Public records of the group’s prior activity show it has operated by combining encryption of systems with the removal of data for potential publication, though specific claims about this victim are limited to the leak-site listing itself.
About deloitte.com
Deloitte.com is the primary domain for Deloitte, a global professional services firm that provides audit, consulting, tax and advisory services to organisations across many industries. Entities of this scale routinely process large volumes of client financial records, employee data and proprietary operational documents as part of their day-to-day work.
What data was at risk
The only data category named in the available record is “internal files exfiltrated in ransomware attack.” No further breakdown of file types or contents has been published. The exact nature of the material therefore remains unconfirmed, and any description of specific records would be speculative.
What's at stake
Exposure of internal files from a professional services firm can create downstream risks for clients whose information appears in those documents, as well as for the firm’s own operational confidentiality. Without Reported Details on the files involved, the practical impact on any individual or client cannot be quantified from public sources.
If your data was in this claimed breach
Individuals concerned about possible exposure should review account statements and credit reports for unusual activity and change passwords on any accounts that may have been referenced in organisational records. Enabling multi-factor authentication on important services provides an additional layer of protection. Readers can also run a free exposure scan of their email address against known breach data to check for appearances in previously published datasets.

Publicly posted by dispossessor — 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.
