Description
In January 2023, The Heritage Group detected and halted a network security incident involving unauthorized access to its IT systems. The Indianapolis-based holding company promptly initiated an investigation to determine whether confidential employee data had been compromised during the breach. Forensic analysis confirmed that the intruder had accessed files containing sensitive personal information belonging to current and former employees and their dependents. The compromised data included first names, last names, physical addresses, and Social Security numbers, though the specific information exposed varied by individual. The company completed its review of affected files to identify impacted parties and the scope of data exposure, though the exact duration of unauthorized access prior to detection was not disclosed in regulatory filings. No evidence suggested customer or client data was affected, with the breach apparently limited to employee-related records. The incident did not disrupt operations across Heritage Group's portfolio of over 30 companies in construction, environmental services, and chemical manufacturing sectors.

On May 1, 2023, The Heritage Group formally notified the Maine Attorney General's Office of the data breach through a mandatory regulatory filing. The same day, the company began mailing individualized data breach notifications to all affected parties, advising them of the exposure of their personal information. The notifications did not specify whether the company would provide credit monitoring services or other remediation measures to impacted individuals. With more than 5,000 employees and $950 million in annual revenue across subsidiaries including Milestone Contractors, Asphalt Materials, and Cirba Solutions, the breach potentially affected a significant portion of the workforce across multiple states. The company's public disclosure emphasized that prompt action was taken to contain the incident upon discovery, though technical details regarding the attack vector, identity of threat actors, and specific containment measures remained undisclosed in available filings. No ransomware payments or extortion attempts were publicly acknowledged in connection with the incident.
