HEMIC - Hawaii Employers' Mutual Insurance Co Listed by SilentRansomGroup Ransomware Group: Ransomware Claim — What’s Alleged & What To Do

On February 3, 2026, Hawaii Employers' Mutual Insurance Co was listed on a site associated with the SilentRansomGroup ransomware operation. The listing states that internal files were exfiltrated during a ransomware attack, though the number of individuals affected and the precise contents of any data remain undisclosed in public reporting. This incident occurs amid a broader pattern of ransomware activity targeting organizations that hold sensitive personal and financial records. Such listings often signal that attackers have obtained material they intend to leverage for extortion or public release, raising questions about data handling practices in sectors that manage workers' compensation claims.

Breaking down the breach

The available information is limited to the February 3, 2026 listing. It indicates that internal files were removed from Hawaii Employers' Mutual Insurance Co systems during a ransomware incident. No confirmation has been issued regarding the volume of data, the timeline of the intrusion, or whether encryption of systems also occurred. The number of people whose information may be involved is not stated.

Who is SilentRansomGroup?

SilentRansomGroup is a ransomware operation that maintains a public leak site where it lists organizations it claims to have compromised. The group typically follows a double-extortion model: encrypting victim systems while also copying data for potential publication if ransom demands are not met. Public records show the group has previously claimed responsibility for incidents involving healthcare, manufacturing, and professional-services entities, often publishing samples of stolen material to pressure targets. In this case the group claims Hawaii Employers' Mutual Insurance Co appears on its listing; no independent verification of the underlying access has been released.

Who is Hawaii Employers' Mutual Insurance Co?

Hawaii Employers' Mutual Insurance Co, founded in 1996 and based in Honolulu, Hawaii, provides workers' compensation insurance. Organizations of this type routinely collect and retain records that include employee medical histories, wage information, claim details, and employer payroll data. Because workers' compensation files frequently contain protected health information and personally identifiable data, a breach at such an insurer can affect both individual claimants and the businesses that purchase coverage.

What was likely exposed

The listing refers only to "internal files exfiltrated in ransomware attack." No inventory of specific data categories has been published. Insurers in this sector commonly store claim forms, medical reports, Social Security numbers, addresses, and employment records. Whether any of those categories were among the files removed is unconfirmed; the exact contents therefore remain unknown outside the organization and the threat actor.

The real-world impact

Individuals whose workers' compensation records are involved could face risks of identity theft or targeted fraud if the files contain personal identifiers or medical details. Employers that rely on the insurer for coverage may encounter operational disruptions if claims processing systems were affected. For the company itself, the incident adds to the operational costs of investigation, potential regulatory notifications, and any required remediation, though the scale of those obligations cannot yet be assessed from public information.
