Quest Diagnostics: Nearly 12 million patients may have been affected by breach

Quest Diagnostics said that an unauthorized user had access to AMCA's personal information, including patients from Quest Diagnostics. "Quest and Optum360 are working with forensic experts to investigate the matter", the company posted in a statement.

Almost 12 million Quest Diagnostics patients are being warned of a data security breach.

The lab assured shareholders in its securities filing that the collections agency did not have access to patients' actual test results.

In response, AMCA says it has taken a number of steps to investigate the matter. "Outsourcing billing to third party vendors is a great way to extract efficiencies by reducing core costs, but it exposes the business and its customers to uncontrollable security risks".

"AMCA's affected system also included credit card or bank account information that was provided by the consumer to AMCA (for those who sought to pay their balance)", the filing reads.

The company revealed the data breach in a filing on Monday with the Securities and Exchange Commission.

If and when you do get notified that your personal data was part of this breach, you should consider signing up with an identity-protection service if such services are not offered to you by one of the affected companies.

Miley Cyrus reveals extra details about her episode of Black Mirror
The episode was unveiled on Netflix at 3:01am EST last night, and is apparently based off of Miley's real life. Within the episode, Cyrus performs as Ashley O, but the track may sound a bit familiar.

Quest Diagnostics and Optum 360 requested information from AMCA about the breach, but AMCA has yet to provide complete, detailed information about the incident to them, the SEC report also said.

On Monday, the U.S. clinical laboratory said that American Medical Collection Agency (AMCA), a billing collections provider that works with Quest, informed the company that an unauthorized user had managed to obtain access to AMCA systems. However, the lab added that it was unable to verify the accuracy of the information received from the collections agency.

The firm told security regulators that it last week learned of a data breach on its web payment system between August 1, 2018, and March 30, 2019.

Since learning of the data breach, AMCA collection requests have been suspended.

A billing collections vendor notified Quest Diagnostics of the discovery of "unauthorized activity" on its online payment page.

With data breaches becoming more common, it's easy for consumers to become less concerned about them. All health plans involved in the breach are being notified and updated accordingly.
