Adamczyk & France CPA PC Data Breach — Class Action Review

Adamczyk & France CPA PC operates as a specialized certified public accounting firm, offering comprehensive tax preparation, financial auditing, corporate accounting, and wealth management services to individuals and businesses alike. Because of the critical financial advisory role they play, firms of this nature routinely amass, process, and store an immense volume of deeply sensitive personal and proprietary information. Their servers and document management systems hold the keys to their clients' financial lives, acting as digital vaults for comprehensive tax returns, corporate ledgers, payroll records, and investment portfolios.

In 2025, Adamczyk & France CPA PC formally reported a data security incident to the Indiana Attorney General, alerting clients and regulatory authorities that unauthorized actors had compromised their network environment. While exact technical forensics vary, breaches affecting accounting and financial services firms typically involve sophisticated ransomware deployments, credential harvesting, or unauthorized external access to digital archives where historical tax filings and client onboarding documents are stored. These threat actors specifically target financial institutions and CPA practices because the concentration of high-value PII allows them to maximize their potential for financial extortion and downstream identity theft.

The exposure resulting from this security failure encompasses a dangerous mix of highly confidential financial and personal identifiers. Victims face the imminent risk of having their Social Security numbers, dates of birth, banking routing and account numbers, and complete historical tax returns leaked or weaponized by bad actors. In the context of a CPA firm breach, the exposure of tax return information and direct deposit details creates an immediate and severe vulnerability to synthetic identity fraud, unauthorized tax refund diversion, and fraudulent credit applications. Unlike basic retail breaches involving credit card numbers that can be easily frozen or canceled, compromised tax and Social Security data exposes victims to long-term, multi-year financial threats.

As a professional entity handling sensitive financial and tax documents, Adamczyk & France CPA PC was bound by strict statutory and common law duties to implement and maintain robust administrative, technical, and physical safeguards. Under federal and state standards, including the Gramm-Leach-Bliley Act (GLBA) Safeguards Rule and Indiana state data protection statutes, financial institutions and accounting firms must encrypt sensitive data at rest and in transit, maintain multi-factor authentication, and conduct rigorous security audits. The occurrence of a successful network intrusion and subsequent data exfiltration strongly indicates a failure to maintain these mandated security protocols, laying the groundwork for potential legal liability and negligence claims.

Receiving a formal data breach notification letter from Adamczyk & France CPA PC serves as official legal acknowledgment that your private financial data was compromised due to inadequate security measures. Under established legal precedents, the receipt of this notice establishes the concrete injury and standing necessary to participate in a class action lawsuit against the firm, meaning you do not have to wait until you suffer actual financial loss to seek accountability. Our law firm is actively investigating potential class action claims on behalf of affected individuals on a contingency fee basis, meaning there are never any out-of-pocket costs or fees unless we successfully recover compensation on your behalf.
