HANSON PROFESSIONAL SERVICES, INC. Data Breach — Class Action Review

Hanson Professional Services, Inc. is an engineering, architectural, and consulting firm that provides comprehensive infrastructure and project development services to both public and private sector clients. Because of the nature of their business — managing large-scale civil engineering, environmental, and transportation projects — the company maintains extensive repositories of sensitive corporate, employee, and subcontractor records. This operational scope requires Hanson Professional Services to collect, process, and store vast amounts of personally identifiable information, including intricate payroll details, banking information for direct deposits, tax records, and detailed personnel files necessary for executing complex municipal and federal contracts.

In 2025, Hanson Professional Services, Inc. reported a significant data security incident to the Illinois Attorney General, joining a growing number of professional services firms targeted by sophisticated cyber adversaries. Incidents of this nature typically involve unauthorized third-party access to corporate networks, potentially compromising centralized databases where personnel files, administrative records, and financial documents are stored. Whether executed via targeted malware, credential harvesting, or vulnerabilities in enterprise software, a breach of this magnitude indicates a breakdown in perimeter defense and network monitoring protocols that allowed unauthorized actors to infiltrate internal systems.

The exposure resulting from the Hanson Professional Services security incident involves highly sensitive categories of personal data, including individuals' full names, Social Security numbers, dates of birth, wage and compensation information, tax return documents, and direct deposit account details. The compromise of this specific combination of data creates severe, immediate risks for affected current and former employees, as well as contractors. Social Security numbers and tax documents are the primary building blocks for identity theft and fraudulent tax filings, while exposed banking credentials directly threaten personal financial security through unauthorized account access and fraudulent wire transfers.

As a custodian of private personnel and corporate data, Hanson Professional Services, Inc. had a legal obligation to implement and maintain robust administrative, physical, and technical safeguards to protect this information. Under state consumer protection statutes, such as the Illinois Personal Information Protection Act, and common law principles of negligence, companies are required to secure sensitive data against foreseeable cyber threats. The occurrence of a data breach compromising core employee data strongly suggests a potential failure in fulfilling these legal duties, particularly regarding network segmentation, access controls, and prompt vulnerability patching.

Receiving a formal data breach notification letter from Hanson Professional Services, Inc. serves as an official acknowledgment that your private information was compromised due to corporate security shortcomings. Legally, this notice establishes the foundation for affected individuals to participate in a class action lawsuit aimed at holding the company accountable for failing to safeguard their data. Importantly, victims do not need to wait until financial fraud or identity theft occurs to take legal action; the increased risk of future harm is sufficient. Our law firm is actively investigating this breach on a contingency fee basis, meaning there are never any out-of-pocket costs or fees unless we successfully recover compensation on your behalf.
