Centers Laboratory, based in New Jersey, has disclosed a data breach impacting over 540,000 individuals. The breach was identified in August 2025, with an official report submitted to the US government. This incident underscores the vulnerabilities faced by healthcare organizations in terms of data protection.
The investigation confirmed that individuals' names, dates of birth, social security numbers, driver’s license numbers, passport numbers, and health-related information were exfiltrated. Such a breach is significant due to the sensitive nature of the data involved.
