This Massive Insurance Data Breach Leaked 1.6 Million Users' Information

A known data breach affecting a major insurance administrator may have compromised the personal information of nearly twice as many people as previously reported. A May 2024 cyberattack on Landmark Admin is believed to include at least 1.6 million people's data, according to an updated filing with the Maine attorney general's office.

Landmark Admin is a Texas-based third-party administrator (TPA) for life insurance and annuity companies like Liberty Bankers Life and American Benefit Life, which offer policies nationwide. A TPA offers insurers support with accounting, regulatory reporting, reinsurance, and IT. That means that while you may not ever have dealt directly with Landmark Admin, your information could still have been leaked.

What happened with Landmark Admin

Landmark Admin suffered a security breach on May 13, 2024, when suspicious activity was detected on the company's networks. It was originally reported in October 2024 that the breach exposed the data of just over 806,00 individuals, but the company now believes that at least 1,613,773 people—and possibly more—may have been impacted.

The compromised information varies by individual may include the following:

• Full name

• Home address

• Social Security number

• Tax identification number

• Driver's license number

• State-issued identification card

• Passport number

• Financial account number

• Medical information

• Date of birth

• Health insurance policy number

• Life and annuity policy information

What affected consumers can do

As always, you can't retroactively protect leaked information, but you can (and should) continue to follow security best practices when it comes to your browsing, communication, and financial habits to mitigate the risk of identity theft.

Review activity on your banking and credit accounts and check your credit report regularly. You can also freeze your credit, place a fraud alert on your file, and lock down your Social Security number. To avoid falling victim to common phishing tactics, never click links or download attachments in emails or messages, don't engage with unknown callers, and go directly to websites by typing in URLs (rather than relying on search results).

If you've been impacted by the Landmark Admin breach specifically, you're eligible for 12 months of credit monitoring and identity protection services through IDX, which includes a $1,000,000 insurance reimbursement policy and ID theft recovery services. Landmark is currently notifying consumers and has a help line at 844-428-5109 that is open from 8 a.m. to 8 p.m ET Monday through Friday to address concerns.
