Know Your Breach: Landmark Admin
Nov 1, 2024 9:16:16 AM
The Target: Landmark Admin is a third-party administrator for insurance companies, offering back-office services like new business processing and claims administration for large insurance carriers.
The Take: The following information related to potentially impacted individuals may have been subject to unauthorized access: first name/initial and last name; 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; and life and annuity policy information.
The Vector: Landmark says it found evidence that the threat actor accessed some files during the attack that contained the personal information of 806,519 people.
This breach highlights the extreme importance of timely software updates for known software vulnerabilities, not only in systems directly under a firm’s control, but in third-party systems the firm relies upon as well. The longer a firm, or its vendors, hold out on deploying the most up-to-date software for their systems, the greater the chance an attacker will exploit the issue.
