Walkowicz, Boczkiewicz, & Co SC Data Breach — Class Action Review

Walkowicz, Boczkiewicz, & Co SC operates as a professional accounting, tax preparation, and financial advisory firm based in the Midwest. Because of the core nature of their business, the firm routinely collects, processes, and maintains an exceptionally high volume of sensitive, personally identifiable information and financial records. Their client base relies on them to manage complex corporate and individual tax filings, payroll processing, asset tracking, and comprehensive financial planning. Consequently, their digital infrastructure houses a vast repository of confidential data that is essential for tax and accounting operations, making them a prime target for cybercriminals seeking high-value financial dossiers.

In 2026, Walkowicz, Boczkiewicz, & Co SC reported a significant data security incident to the Indiana Attorney General, alerting clients and regulatory authorities that unauthorized actors had gained access to their network environment. While the exact vector of the breach remains under active investigation, incidents of this nature typically involve sophisticated cyberattacks such as ransomware deployment, credential harvesting, or unauthorized intrusion into legacy databases and file-sharing systems. Professional services firms often manage extensive networks containing legacy client files and third-party software integrations, creating potential blind spots that malicious actors actively scan for and exploit to bypass perimeter security controls.

The exposure resulting from this incident encompasses a dangerous aggregation of private records, including full names, Social Security numbers, dates of birth, detailed tax return documentation, wage and compensation records, and direct deposit banking details. When compromised, this combination of financial and identifying information creates severe, long-term risks for victims. Cybercriminals can exploit stolen tax data and Social Security numbers to file fraudulent tax returns, intercepting refunds before legitimate taxpayers can file. Furthermore, exposed banking details and payroll information directly facilitate identity theft, unauthorized account takeovers, and targeted financial fraud that can take years to fully resolve.

As a custodian of sensitive financial and tax data, Walkowicz, Boczkiewicz, & Co SC had strict legal and regulatory obligations to implement robust cybersecurity measures. Under federal standards enforced by the Federal Trade Commission (FTC) under the Gramm-Leach-Bliley Act (GLBA) guidelines for tax preparation professionals, as well as applicable Indiana state data protection statutes, firms handling this level of private information must maintain comprehensive administrative, technical, and physical safeguards. The occurrence of a breach that compromises deep financial files strongly suggests potential failures in data encryption, multi-factor authentication enforcement, or timely vulnerability patching, pointing toward actionable negligence in failing to adequately protect client data.

Receiving a data breach notification letter from Walkowicz, Boczkiewicz, & Co SC is a formal legal admission that your confidential records were compromised due to inadequate security practices. Under the law, the receipt of this notice establishes the legal standing necessary to participate in a class action lawsuit aimed at holding the firm accountable for failing to protect your information. Importantly, victims do not need to wait until financial theft occurs to take legal action; the increased risk of future identity theft and the costs associated with credit monitoring are recognized harms. Our firm evaluates these cases on a contingency fee basis, meaning there are no out-of-pocket costs or fees unless we successfully recover compensation on your behalf.
