Hawaii Employers’ Mutual Insurance Company (HEMIC) Cyberattack, What Businesses and Workers Need to Know

While HEMIC has not publicly confirmed the breach, sensitive data — including protected health information and personal identifying information — is believed to have been compromised. HEMIC covers nearly 7,000 businesses and 75,000 workers across Hawaii. No settlement exists. Attorneys are actively investigating whether a class action lawsuit can be filed on behalf of affected individuals.

What the Cyberattack Allegedly Involved
The SilentRansomGroup published a post on its ransomware leak site dated February 27, 2026, listing HEMIC as a victim. The available metadata does not specify whether the attack involved encryption, data exfiltration, or both, and no ransom figure or negotiation terms were disclosed in the public posting.
Ransomware.Live, which monitors threat actor activity, reported that images published by the group indicated that sensitive data — including protected health information and personal identifiers — may have been compromised.
The specific method used to gain access to HEMIC’s systems has not been disclosed. HEMIC has not confirmed the attack, identified affected systems, or described any remediation steps taken.
Who Could Be Included
HEMIC operates as one of Iowa’s largest private workers’ compensation insurers, covering nearly 7,000 businesses and 75,000 workers. In addition to workers’ compensation insurance, it offers commercial insurance products and temporary disability insurance.
Individuals potentially at risk include:
- Employees covered under HEMIC workers’ compensation policies
- Business owners and HR administrators who submitted business and employee records to HEMIC
- Individuals who filed workers’ compensation or temporary disability claims with HEMIC
- Any individual whose personal or health information was stored in HEMIC’s systems
Because HEMIC administers workers’ compensation and disability claims, the data it holds is likely to include sensitive categories such as medical records, injury information, employment records, Social Security numbers, and financial details. The full scope has not been confirmed.

What Information May Have Been Exposed
HEMIC has not confirmed what categories of data were involved. Based on the nature of HEMIC’s business and the type of data typically held by workers’ compensation and disability insurers, potentially at-risk information may include:
- Full names and dates of birth
- Social Security numbers
- Home addresses and contact information
- Employment and wage records
- Workers’ compensation claim details
- Medical records, injury descriptions, and treatment information
- Health insurance information
- Financial account information
Until HEMIC issues an official breach notification, the precise categories of exposed data remain unconfirmed.
Legal Action: Class Action Investigation Underway
Attorneys are investigating whether a class action lawsuit can be filed against HEMIC. If filed and successful, a lawsuit could provide affected individuals with compensation for loss of privacy, time spent addressing the breach, out-of-pocket costs related to identity monitoring, and other harms.
No lawsuit has been filed as of the date of this article. This is an early-stage investigation. Affected individuals — including employees, claimants, and businesses that submitted records to HEMIC — may have legal rights worth exploring at no cost.
What Affected Individuals Should Do Now
Whether or not you have received a notification from HEMIC, take these steps if you believe you may be affected:
Monitor your mail. Under Hawaii law, HEMIC must notify affected residents without unreasonable delay once a breach is confirmed. Watch for an official notification letter.
Check the HHS breach portal. Visit ocrportal.hhs.gov to see if HEMIC files a formal HIPAA breach notification. This is publicly searchable and updated regularly.
Place a credit freeze. Contact Equifax, Experian, and TransUnion directly to freeze your credit at no cost. This prevents new accounts from being opened in your name.
Set up fraud alerts. A free one-year fraud alert placed with any one bureau is automatically shared with the other two, prompting lenders to take extra verification steps.
Review your workers’ comp and insurance statements. Watch for unfamiliar claims, benefit changes, or communications you did not initiate — potential signs of insurance or medical identity fraud.
Contact an attorney. If your data was exposed, a consumer protection or data breach attorney can help you understand your options at no cost. Consultations are typically free.
Broader Context: Insurance Companies Are Prime Targets
The HEMIC incident is part of an accelerating pattern of ransomware attacks specifically targeting insurance companies. Recent attacks highlight the growing risks posed by third-party vendors and the critical importance of incident response speed, notification timing, and forensic analysis in mitigating legal and regulatory exposure.
The Aflac breach — which exposed the data of 22.65 million individuals in June 2025 — was part of a broader campaign that also hit Erie Insurance and Philadelphia Insurance Companies, triggering more than 20 lawsuits and federal investigations. The attack was executed through social engineering rather than malware, demonstrating that insurance companies face threats from multiple attack vectors.
According to Cyber Security News, SilentRansomGroup was responsible for multiple data breaches targeting law firms in 2025, suggesting the group has now expanded its focus to financial and insurance sector targets.
