NEW YORK – Laboratory Corporation of America confirmed on Wednesday that it has experienced a breach of an internal data system used by its integrated oncology business.
The company did not say what kind of data might have been exposed during the breach but said that it disabled access to the exposed system upon confirming the vulnerability. "This did not affect any customer, client, vendor, or other external systems," LabCorp said, adding neither the LabCorp Diagnostics nor Covance Drug Development businesses were affected.
It continues to investigate the incident and will take action, including notifying affected patients or regulatory authorities, as it determines it is required or appropriate.
The breach is the second in recent months for LabCorp, following an incident the company disclosed in June 2019 in which a breach of external payment collection agency American Medical Collection Agency exposed financial and/or personal data of as many as 7.7 million LabCorp customers.
The AMCA breach affected other laboratories including Quest Diagnostics, which had 11.9 million of its customers potentially exposed.
