bakertilly Listed by cuba Ransomware Group: Ransomware Claim — What’s Alleged & What To Do
The bakertilly Listed by cuba Ransomware Group (reported December 30, 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.
What happened
Bakertilly was added to the cuba ransomware group's leak site on December 30, 2021. The group claims to have stolen internal data in the course of a ransomware attack.
No further details on the timing of the intrusion, the method of access, the scale of exfiltration, or any ransom demand have been disclosed. The number of individuals potentially affected is also not known.
Who is cuba?
Cuba is a ransomware operation that has been publicly tracked since at least 2020. The group typically uses double-extortion tactics, encrypting systems and threatening to publish stolen files if a ransom is not paid.
Its operators have posted victim names and sample data on a dedicated leak site when negotiations stall. The group has targeted organizations across multiple sectors and geographies, though specific claims made about any single victim require separate verification.
About bakertilly
Bakertilly operates as a professional services firm offering accounting, audit, tax, and advisory work to businesses and other organizations. Firms of this type routinely process financial records, tax filings, and other internal documents that can contain sensitive commercial and personal information.
A listing on a ransomware leak site draws attention because such organizations hold data that can affect both their own operations and the clients or employees whose information they manage.
What was likely exposed
The available information states only that internal files were exfiltrated. No inventory of specific file types or data categories has been released.
Organizations in this sector commonly maintain client financial statements, tax documents, employee records, and correspondence. The exact contents of the material claimed by the group have not been confirmed.
Why it matters
Publication of internal files can create ongoing risks for the individuals or entities named in those records, including potential misuse of financial or identity-related details. The absence of confirmed data types leaves the scope of any exposure unclear.
For the organization, the incident adds to the operational and reputational consequences that follow ransomware activity, regardless of whether encryption occurred or files were ultimately published.
If your data was in this claimed breach
Monitor financial accounts and credit reports for unusual activity. Change passwords for any accounts that may have been referenced in organizational records and enable multi-factor authentication where available.

Publicly posted by cuba — 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.
