Description
On November 5, 2022, Cleveland Brothers Holdings, Inc. (CBH) detected suspicious activity within its computer network. The company immediately secured its systems and initiated an internal review of its policies and procedures. CBH engaged third-party forensic specialists to conduct a formal investigation into the incident. The investigation confirmed that an unauthorized party had gained access to certain portions of the corporate network. Forensic analysis later determined that accessible files contained confidential consumer information, though the full scope of access wasn't immediately clear. CBH undertook a comprehensive review of the compromised files to identify affected individuals and specific data elements exposed. The breached information included consumers' names and Social Security numbers, with the exact combination varying by individual.
CBH completed its forensic review and impact assessment approximately three months after initial detection. On February 17, 2023, the company formally filed a notice of data breach with the Maine Attorney General's office. That same day, CBH began mailing individualized data breach notifications to all affected consumers. The notifications advised recipients that their sensitive personal information had been compromised in the security incident. As a heavy equipment distributor operating 29 locations across Pennsylvania, West Virginia, and Maryland, the breach potentially impacted customers and other individuals whose data was maintained in corporate systems. No specific details were disclosed regarding the number of affected individuals beyond "thousands," the duration of unauthorized access, or the exact method of network intrusion. The company's public disclosures focused exclusively on compromised Social Security numbers and names without mentioning financial data or operational system impacts.
