  • •A separate class action lawsuit resulted in a $6.1 million settlement for a later breach.

A data breach involving Labcorp's debt collector, AMCA, exposed personal information of over 27.5 million individuals, including 10.2 million Labcorp patients. The breach occurred between August 1, 2018, and March 30, 2019, when a hacker accessed AMCA's internal systems, compromising sensitive data such as Social Security numbers and payment card information. New York Attorney General Letitia James announced a settlement that mandates Labcorp to pay $2.3 million and implement significant reforms to enhance data security practices. Additionally, a separate class action lawsuit concerning a later breach discovered in October 2024 has led to a $6.1 million settlement for impacted individuals, specifically those who received lab tests through Planned Parenthood. This breach affected approximately 1.6 million people and involved the exposure of personally identifiable information and protected health information. Labcorp is now required to improve its information security program and vendor management practices to prevent future breaches.
