Medical testing giant LabCorp. said today personal and financial data on some 7.7 million consumers were exposed by a breach at a third-party billing collections firm. That third party – theAmerican Medical Collection Agency (AMCA) – also recently notified competing firm Quest Diagnostics that an intrusion in its payments Web site exposed personal, financial and medical data on nearly 12 million Quest patients.
Just a few days ago, the news was all about how Quest had suffered a major breach. But today’s disclosure by LabCorp. suggests we are nowhere near done hearing about other companies with millions of consumers victimized because of this incident: The AMCA is a New York company with a storied history of aggressively collecting debt for a broad range of businesses, including medical labs and hospitals, direct marketers, telecom companies, and state and local traffic/toll agencies.
