What Happened in the Landmark Admin Data Breach?

Landmark Admin, a Texas-based third-party administrator (TPA), provides services such as policy accounting, regulatory reporting, IT infrastructure, and reinsurance support to major insurers like Liberty Bankers Life and American Benefit Life.

On May 13th, 2024, Landmark detected suspicious activity on its systems. Initial estimates suggested that 806,519 individuals were impacted. Later, an updated report filed with the Maine Attorney General’s Office in April 2025 increased that number to 1,613,773 individuals.

The forensic investigation is ongoing, which means the final number could rise further. Affected individuals will receive personalized notifications by mail specifying what data was compromised.

What Data Was Exposed?

The breach compromised a wide range of sensitive data, which varies from person to person. The data includes:

  • Full name
  • Home address
  • Social Security Number (SSN)
  • Tax Identification Number (TIN)
  • Driver’s license or state-issued ID
  • Passport number
  • Financial account details
  • Medical and health insurance information
  • Life and annuity policy data
  • Date of birth

Because the data types vary per person,  you will get a custom notice outlining the specific exposures.

What Are the Risks of This Breach?

The exposed data can put you at a greater risk of:

  1. Identity Theft & Financial Fraud

With SSNs, policy details, and banking data exposed, attackers could engage in fraudulent claims, unauthorized account creation, or tax fraud.

  1. Healthcare Privacy Violations

Medical and insurance details may enable fraudsters to submit false claims or access health services in your name.

  1. Phishing and Social Engineering

The combination of financial and personal information can be used to send you convincing phishing attempts or manipulate you into disclosing further data.

What Should You Do If Your Data Was Compromised?

If you receive a data breach notification from Landmark Admin, here are the steps you should take immediately:

  1. Enroll in Identity Protection Services

Landmark is offering 12 months of identity theft protection and credit monitoring — sign up without delay.

  1. Monitor Financial and Insurance Accounts

Review bank statements, insurance activity, and credit reports. Report suspicious behavior right away.

  1. Request a Fraud Alert or Credit Freeze

Contact the credit bureaus to prevent new accounts from being opened in your name.

  1. Watch for Phishing Attempts

Be cautious of emails or calls asking for further information, especially if they reference your insurance or financial services.

How to Minimize Damage After a Breach

To protect yourself now and in the future, you must:

  1. Use strong, unique credentials, ideally managed via a secure password manager.
  2. Watch for signs of identity misuse. If you spot anything unusual, act quickly to limit further exposure.
