Zuber Gardner CPAs pt.2 Listed by everest Ransomware Group: Ransomware Claim — What’s Alleged & What To Do
The Zuber Gardner CPAs pt.2 Listed by everest Ransomware Group (reported June 12, 2024) 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 June 12, 2024, the accounting firm Zuber Gardner CPAs pt.2 was listed by the ransomware group known as everest. Public reporting indicates that the group claims to have exfiltrated internal files during a ransomware attack and has threatened to publish them if the company does not make contact within 24 hours. The number of people affected remains unknown, and independent confirmation of the full scope is limited.
The listing matters because accounting firms routinely handle sensitive financial and personal records for clients. Any confirmed exposure of such material can create lasting risks of fraud, identity misuse, and professional disruption, even when exact details stay undisclosed.
Breaking down the breach
According to the available record, everest listed Zuber Gardner CPAs pt.2 on its leak site on June 12, 2024. The group asserts that the company’s files remain on its servers and that it is “stupid to think that they are not there.” It gave the firm 24 hours to make contact or face publication of the files and notification of clients. The listing references the firm’s website and a 1 GB file hosted on a third-party sharing service. No further technical details about the intrusion method, exact date of compromise, or total volume of data beyond the stated 1 GB sample have been publicly confirmed. The number of individuals affected is listed as unknown.
Because the information originates from the threat actor’s own claim, it should be treated as unverified until corroborated by the firm or independent investigators. No official statement from Zuber Gardner CPAs pt.2 confirming or denying the incident appears in the public record provided.
Inside everest
Everest is a ransomware group that has operated by encrypting victim systems and exfiltrating data, then threatening to leak the material if a ransom is not paid. Like other groups in this category, it maintains a public leak site where it posts victim names, sample files, and deadlines. Its typical pattern involves double-extortion: locking systems while also holding stolen data for leverage. Prior public activity by everest has included listings of organizations across multiple sectors, often accompanied by countdown timers and partial data dumps intended to pressure payment.
In this case the group claims the files of Zuber Gardner CPAs pt.2 are still under its control and that publication will follow if contact is not made. No additional statements from everest specific to this victim—beyond the listing text and the 1 GB sample reference—have been reported. The group’s broader reputation rests on its willingness to follow through on publication threats when negotiations fail, a tactic documented across multiple earlier incidents.
Who is Zuber Gardner CPAs pt.2?
Zuber Gardner CPAs pt.2 is an accounting and certified public accounting practice. Firms of this type prepare tax returns, conduct audits, provide bookkeeping, and advise clients on financial compliance. They typically hold detailed records that include client names, Social Security or tax identification numbers, bank account details, income statements, and correspondence related to financial affairs. Because the work is regulated and trust-based, a breach at such an organization can affect both the firm’s professional standing and the privacy of the individuals and businesses it serves.
A ransomware incident targeting an accounting practice is consequential precisely because of the concentrated sensitivity of the data. Even limited exfiltration can expose clients to identity theft or tax-related fraud, while the firm itself may face regulatory scrutiny, client attrition, and operational recovery costs. Public detail on the firm’s size, location, or specific client base is limited in the available record.
The information in question
The facts state that internal files were exfiltrated in a ransomware attack. No more granular inventory of data types—such as specific categories of personal identifiers, financial statements, or client lists—has been disclosed. Organizations of this kind ordinarily maintain tax documents, payroll records, engagement letters, and supporting financial data. Whether any of those categories appear in the claimed 1 GB sample remains unconfirmed. Readers should therefore treat the precise contents as unknown until verified by the firm or forensic analysis.
What's at stake
For individuals whose information may have been among the internal files, the practical risks include identity theft, fraudulent tax filings, and unauthorized access to financial accounts. Even partial records can be combined with other publicly available data to enable social-engineering attacks. For the firm, the stakes involve potential regulatory notification duties, loss of client confidence, and the cost of forensic investigation and system restoration. Because the number of people affected is unknown, the full scale of personal impact cannot yet be measured. The threat actor’s stated intention to notify clients if the files are published would itself amplify reputational and operational pressure.
What to do if you're exposed
If you are a client or employee of Zuber Gardner CPAs pt.2, or believe your data may have been involved, take the following practical steps:
- Monitor bank, credit-card, and tax accounts for unexpected activity and enable available transaction alerts.
- Place a free fraud alert or credit freeze with the major credit bureaus if personal identifiers may have been exposed.
- Change passwords on any accounts that share credentials with the firm and enable multi-factor authentication wherever possible.
- Retain copies of any notices you receive from the firm and document unusual contacts that reference your financial information.
- Run a free exposure scan of your email address to check whether it has already appeared in known breach data sets.
These measures do not eliminate risk, but they reduce the window of opportunity for misuse while more definitive information becomes available. Public detail on this incident remains limited to the threat actor’s claim and the June 12, 2024 listing date.

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.
