What information is involved in the illumifin Corporation Data Breach?

Compromised information may include:

Your Personally Identifiable Information (PII) includes information that can be used to identify you. Companies that store PII are legally required to protect it. When this information is exposed in a data breach, it can be used by cybercriminals to commit identity theft, financial fraud, or other forms of misuse.

Because illumifin provides insurance and administrative services, a subset of the exposed data may qualify as Protected Health Information (PHI). PHI includes medical and insurance-related information protected under federal and state privacy laws. When PHI is compromised, it can be used to commit medical identity theft, insurance fraud, or related crimes—often in combination with other exposed personal data.

If your information was involved in this breach, one of the most important steps you can take is to carefully monitor financial accounts, credit reports, and insurance statements for suspicious activity. Impacted individuals should also follow any guidance provided in the notification letter, including steps related to fraud alerts, credit freezes, or identity theft monitoring services.

California residents may have enhanced rights under the California Consumer Privacy Act (CCPA) and other state privacy laws. Individuals impacted by the illumifin data breach may have legal rights when companies fail to adequately safeguard sensitive personal or medical information.
