From the AG filing description
Blair C Diaz CPA PC operates as a professional accounting and financial services firm, providing comprehensive tax preparation, bookkeeping, corporate auditing, and payroll management to individual clients and businesses throughout Indiana. Because of the nature of its operations, the firm routinely collects, processes, and stores an immense volume of deeply sensitive financial and personal data. To perform accurate tax filings and financial assessments, accounting firms like Blair C Diaz CPA PC must maintain complete financial records, asset portfolios, and identity verification documents, making them prime targets for cybercriminals seeking high-value dossiers containing everything needed for financial fraud and identity theft. In 2026, Blair C Diaz CPA PC formally reported a significant security incident to the Office of the Indiana Attorney General. While details continue to emerge through ongoing forensic investigations, data security incidents impacting accounting and tax firms typically involve sophisticated external network intrusions, ransomware deployments, or compromised third-party vendor applications. In many cases, threat actors exploit vulnerabilities in file-transfer mechanisms or deploy malicious payloads designed to bypass perimeter defenses, gaining unauthorized access to internal databases where client financial records and tax documents are stored. The exposure resulting from this breach threatens individuals with severe, long-term risks due to the specific categories of data typically held by certified public accountants. Compromised information frequently includes full names, Social Security numbers, dates of birth, detailed tax return documentation, wage and compensation records, bank account routing and account numbers, and corporate financial statements. When Social Security numbers and tax returns are leaked alongside banking details, victims face an immediate and elevated risk of fraudulent tax filings, unauthorized credit card applications, bank account takeovers, and synthetic identity creation that can take years to resolve. As a professional entity handling sensitive financial information, Blair C Diaz CPA PC was bound by rigorous legal and regulatory obligations to safeguard consumer data under state data protection statutes, the Gramm-Leach-Bliley Act (GLBA) where applicable, and general common-law duties of care. These legal frameworks mandate the implementation of robust administrative, technical, and physical safeguards—such as multi-factor authentication, robust encryption standards, and continuous network monitoring—to protect confidential client files. A successful data breach of this magnitude strongly suggests that systemic vulnerabilities or lapses in security protocols may have compromised these mandatory statutory protections. Receiving an official data breach notification letter from Blair C Diaz CPA PC is a formal acknowledgment that your private financial and personal records were compromised while under the firm's custody. Under modern legal standards, the receipt of such a notice often establishes the legal standing necessary to participate in a class action lawsuit aimed at holding the company accountable for its security failures. Affected individuals do not need to wait until they have suffered actual financial loss or fraudulent activity to seek legal recourse. Our firm is currently investigating potential claims on a contingency fee basis, meaning there are never any out-of-pocket costs or fees unless we successfully recover compensation on your behalf.
Under the Indiana data breach notification law, you may have a legal claim against Blair C Diaz CPA PC if any of the following apply:
Based on the data types reported in this filing:
Your SSN is the master key to your identity. Once exposed, criminals can open new lines of credit, take out loans, or file taxes in your name.
Combined with a name and other leaked data, date of birth helps criminals pass identity verification questions at banks and government agencies.
Common categories of compensation in data breach class actions
Courts recognize that the time spent monitoring accounts, placing credit freezes, and dealing with the aftermath of a breach has real economic value. This category of damages is recoverable even without direct financial loss.
Professional credit monitoring services cost $10–$40 per month. Identity theft restoration services, if needed, can cost hundreds of hours and thousands of dollars. Courts have awarded these costs as direct damages in SSN breach cases.
Direct financial losses resulting from the breach — unauthorized charges, fraudulent transfers, or fees incurred through fraud — are recoverable as compensatory damages. Banks may reverse some charges; a class action recovers the remainder and associated costs.
Data breach victims regularly report anxiety, loss of sleep, and ongoing fear of identity theft. These non-economic harms are cognizable injuries in data breach litigation, particularly in cases involving SSN or medical record exposure.
Note: an attorney general breach filing does not by itself establish a settlement fund, a payment amount, or a claim deadline. If an official settlement notice is later issued, rely on that notice for payment details and deadlines.
No. Under Indiana data breach notification law and federal law, the unauthorized exposure of your personal data — regardless of whether it has been actively misused — can be sufficient grounds for a claim. The breach itself is the injury.
Nothing. The Law Office of David S. Harris handles data breach cases on contingency — you pay zero upfront and owe nothing unless compensation is recovered.
Immediately place a free credit freeze at all three bureaus (Equifax, Experian, TransUnion). A freeze blocks new accounts from being opened in your name. Then file a complaint with the FTC at IdentityTheft.gov and contact our office — SSN exposure is one of the most serious breach types.
Banks may reverse fraudulent charges, but they are not obligated to compensate you for time lost, stress, or indirect damages. A class action claim against the breached company can recover those additional categories of harm.
State statutes of limitations for data breach claims typically run 2–4 years from the date of the breach or its discovery. Because this breach was recently disclosed, the window is open — but acting early preserves your options and strengthens the case.
Accepting free credit monitoring from Blair C Diaz CPA PC does not waive your right to pursue legal action unless you signed a specific release waiving claims. In most cases, victims who accepted monitoring can still file.
Not necessarily. Many data breach victims are never notified directly. If your personal information was held by Blair C Diaz CPA PC during the relevant period, you may still qualify even without receiving a letter. A free eligibility review can confirm your status.
