A significant data breach involving a prominent insurance administrator could have exposed personal details of nearly double the previously estimated number of individuals. The cyberattack that took place in May 2024 has reportedly compromised the information of around 1.6 million people, as highlighted in a recent disclosure from the Maine attorney general’s office.

Landmark Admin serves as a third-party administrator (TPA) based in Texas, providing support to life insurance and annuity firms, including Liberty Bankers Life and American Benefit Life, across the nation. TPAs assist insurers with vital functions such as accounting, regulatory compliance, reinsurance, and information technology. Consequently, even if individuals have not interacted directly with Landmark Admin, their personal information could be at risk.

Details of the Landmark Admin Breach

On May 13, 2024, Landmark Admin identified unusual activity within its networks, leading to the discovery of the security breach. Initially, in October 2024, it was reported that the breach had affected just over 806,000 individuals. However, the latest assessments indicate that the number of impacted individuals may exceed 1,613,773.

The compromised data may include a diverse range of personal information, such as:

• Full name

• Residential address

• Social Security number

• Tax identification number

• Driver’s license number

• State-issued ID number

• Passport number

• Bank account number

• Medical records

• Date of birth

• Health insurance policy number

• Details regarding life and annuity policies

Steps for Affected Consumers

While it is not possible to reverse the leakage of private information, adhering to best security practices is essential for reducing the risk of identity theft. Individuals should stay vigilant regarding their online and financial activities.

Regularly monitor transactions in banking and credit accounts, and frequently review your credit reports. Options such as freezing credit, placing a fraud alert, and securing your Social Security number can strengthen your defenses. To protect against phishing scams, avoid clicking on links or opening attachments in unsolicited emails or messages, refrain from engaging with unknown callers, and always access websites by manually entering URLs instead of relying on search engine results.

For those affected by the Landmark Admin breach, they are entitled to a year of credit monitoring and identity protection services provided by IDX, which includes a reimbursement policy of up to $1,000,000 and resources for recovering from identity theft. Landmark Admin is currently in the process of notifying affected consumers and has set up a helpline at 844-428-5109, available from 8 a.m. to 8 p.m. ET, Monday through Friday, to assist with inquiries.
