What we know

Harmony Insurance Co. recently suffered a ransomware attack that compromised the sensitive personal and health information of approximately 450,000 policyholders. The insurer formally reported this security failure to the Florida Department of Legal Affairs on June 28, 2026. This incident has already triggered multiple legal actions, which have now been consolidated into a pending class action lawsuit in the United States District Court for the Southern District of Florida. The breach exposed critical information including Social Security numbers, detailed medical records, and specific insurance policy data. Because cybercriminals now possess your Social Security number and medical history, you face a heightened, long-term risk of targeted identity theft, fraudulent medical billing, and unauthorized insurance claims. This combination of data allows bad actors to open fraudulent accounts in your name or access healthcare services at your expense. If you received a data breach notification letter in the mail from Harmony Insurance Co., you may be eligible to participate in the ongoing class action lawsuit. You can request a free case review right now to explore your legal options with zero upfront out-of-pocket costs.
