According to a statement released Monday, Quest's billing collections service provider, American Medical Collection Agency (AMCA), notified them that an unauthorized user had access to AMCA's system containing personal information AMCA received from various companies, including Quest.

Quest Diagnostics' laboratory test results were not provided to the vendor, AMCA, and were not compromised by the incident.

Quest said it doesn't have "detailed or complete information about the AMCA data security incident, including which information of which individuals may have been affected". And Quest has not been able to verify the accuracy of the information received from AMCA. Headquartered in NY - the business capital of the world - FBN launched in October 2007 and is the leading business network on television, topping CNBC in Business Day viewers for the second consecutive year. 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 NY 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. The statement added: For approximately 327 million of these guests, the information includes some combination of name, mailing address, phone number, email address, passport number, Starwood Preferred Guest ("SPG") account information, date of birth, gender, arrival and departure information, reservation date, and communication preferences.


"The breath of information available from healthcare companies is far greater than most breaches", Hayes said.

The massive data breach impacts almost 12 million patients.

The company "has been working and will continue to work diligently, along with Optum360, AMCA and outside security experts to investigate the AMCA data security incident and its potential impact on Quest Diagnostics and its patients".


"The Quest breach targeted mostly financial data, and personal information such as SSNs".

My guess is we will soon hear about many other companies and millions more consumers impacted by this breach at the AMCA.

"This is the second breach that Quest has suffered in three years, and as a publicly traded company, that can lead to serious repercussions with shareholder trust, stock price and brand reputation", noted Ben Goodman, the VP of global strategy and innovation at ForgeRock.
