HEMIC Data Breach: SilentRansomGroup Claims Responsibility for Potential Exposure of Sensitive Data

On February 27, 2026, the Hawaii Employers' Mutual Insurance Company (HEMIC) reportedly experienced a data breach, though the company has not issued an official confirmation. The incident may have compromised sensitive information, including protected health and personal data, affecting nearly 7,000 businesses and 75,000 workers across Hawaii.

HEMIC provides workers’ compensation, commercial insurance, and temporary disability coverage to a diverse range of industries. The threat actor SilentRansomGroup has claimed responsibility for the breach, according to reports from Cyber Security News.

While details remain unconfirmed, legal investigations are underway to determine whether a class action lawsuit can be filed on behalf of potentially affected individuals. The breach could have implications for policyholders, including risks of identity theft, financial fraud, and other privacy-related harm. Further updates are expected as the situation develops.
