Horizon Actuarial Services, LLC

On May 10, 2022, the Maine Office of the Attorney General disclosed a data breach affecting **Horizon Actuarial Services, LLC**, which occurred between **November 10 and November 17, 2021**. The incident involved **unauthorized external system access (hacking)**, compromising sensitive personal information of approximately **2,011 Maine residents**, including **Social Security numbers (SSNs)**. Such data exposure significantly increases the risk of **identity theft and financial fraud** for the affected individuals. In response, the company offered **12 months of identity theft protection services through Kroll, LLC** to mitigate potential harm. The breach highlights vulnerabilities in Horizon Actuarial’s cybersecurity defenses, particularly in safeguarding highly sensitive personally identifiable information (PII). While no immediate financial losses or large-scale fraud were reported, the exposure of SSNs—critical identifiers for credit, employment, and government services—poses long-term risks for the victims. The incident underscores the need for stronger access controls and monitoring to prevent similar intrusions in the future.
