It's not just Quest: LabCorp says it was hacked, too

Three Democratic Senators, including one presidential hopeful, are pressing blood-testing giant Quest Diagnostics for answers after a recent data breach that the company says exposed the personal data of 11.9 million patients.

The breach comes just days after Quest Diagnostics announced 12 million patients were affected by a data breach.

Up to 7.7 million LabCorp patients may have had personal data exposed as a result of a massive breach at a third-party billing collection agency.

LabCorp says in a filing with the Securities and Exchange Commission that its billing collections vendor, American Medical Collection Agency, had unauthorized activity on its payment page.

"This data breach is yet another example of how fragile our information infrastructure is, and how vulnerable all of us are to cyber hacking", Nessel says in a written statement.

"In response to initial notification of the AMCA Incident, LabCorp ceased sending new collection requests to AMCA and stopped AMCA from continuing to work on any pending collection requests involving LabCorp consumers", the SEC notice states. Warner asked the company to provide additional information regarding the breach and the company's processes for selecting and monitoring sub-contractors and vendors.

In an emailed statement Monday, AMCA said it was taking steps to increase the security of its systems, including migrating its web payment portal services to a third-party vendor.

Apart from LabCorp, AMCA is reportedly also getting in touch with affected customers. "Moreover, such breaches force victims to contend with identity theft that may lead to irreparable harm to their credit reports and financial futures, and to confront the real possibility that their confidential medical information and history has been exposed". The medical and health-care sector accounted for 363, or 29 percent, of those incidents.

It also said that AMCA has not provided "detailed or complete information" about the hack, including which customers might have been affected. Last month, the U.S. Justice Department charged two Chinese nationals in the attack.
