What happened

illumifin Corporation is a third-party administrator (TPA) serving more than 100 insurance carriers in life, long-term care, health, and annuity lines. Its functions include policy administration, underwriting support, claims assessment, and policyowner services. Sources conflict on illumifin’s primary headquarters — HHS OCR and Minnesota state filings list Woodbury, MN; California filings reference Greenville, SC. The MN-listed OCR filing of 5,385 affected individuals is the entry covered on this page.

On November 4, 2025, illumifin detected unusual network activity, initiated incident response, and engaged forensic experts. On November 10, 2025, forensics confirmed that exfiltrated files contained client / carrier data. illumifin notified affected insurance carrier clients on January 9, 2026 and provided them with affected-individual lists by February 25, 2026. Individual notification mailing began on March 13, 2026, and illumifin filed with the California AG on March 31, 2026.

Aggregate exposure across all illumifin clients is 97,781 individuals, distributed across state filings: TX 6,724, IN 1,903, SC 786, NH 37, MA 21, plus the MN 5,385 covered here. A separate OCR filing under Liberty Bankers Life lists 20,202 additional affected individuals — that’s a downstream carrier filing covered on its own page.

No ransomware group has publicly claimed responsibility. No leak-site listing has been observed. The behavior pattern (network intrusion + file exfiltration + multi-month dwell to notification) is consistent with extortion-style intrusion.

What was stolen

  • Full name, home address
  • Social Security number
  • Date of birth
  • Insurance policy information
  • Underwriting and claims data
  • Health insurance information
  • Medical record information
  • Financial account number

The combination of SSN + medical records + financial accounts represents a broad TPA-typical exposure — life, long-term care, and annuity policy data are particularly attractive for fraud given the asset values and beneficiary information involved.

What illumifin is offering

  • Complimentary identity-monitoring membership: 1-year coverage for some affected individuals, 2-year coverage for others depending on data-sensitivity tier per individual

What to do

  1. Enroll in the offered identity monitoring through the activation code in your letter.
  2. Place free credit freezes at all three bureaus. Full SSN is in scope.
  3. File IRS Form 14039.
  4. Cancel and reissue any payment cards that may be tied to financial account information.
  5. Watch your insurance Explanation of Benefits statements for unfamiliar claims.
  6. Stop the ongoing flow of your insurance and medical data through TPAs. HealthConsent files HIPAA restriction requests covering insurance administration and claims-processing data flows.

Stop your data from spreading further

Credit monitoring covers your wallet. HealthConsent covers your health records.

Your stolen diagnoses, test results, and medical record numbers don’t expire when the free credit-monitoring window ends. HealthConsent automates HIPAA restriction requests and opt-outs across providers, insurers, HIEs, and prescription networks so the data taken in this breach can’t keep being shared and sold by other entities downstream.
