Does Quest Diagnostics plan to provide notice to each affected consumer, or will it rely on a consumer-initiated checks to inform them?

The information which was stored on the affected system of the American Medical Collection Agency system is inclusive of bank account information, medical information, credit card numbers, personal information as well as the Social Security numbers, as per told by the SEC filing.

The AMCA hack exposed the personal, financial and medical data on some 11.9 million patients of Quest Diagnostics.

Quest Diagnostics has warned its 12 million customers that their personal, financial and medical data may have been exposed.

The information on AMCA's systems included medical information and financial information, but AMCA had nothing to do with laboratory tests and, therefore, the tests were not impacted by the breach.

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.

In its press release, Quest stated that the AMCA first notified Quest and Optum360 - a Quest contractor - of "potential unauthorized activity on AMCA's web payment page" on May 14, 2019.

What processes does Quest Diagnostics have in place to ensure that the companies it outsources patient information to responsibly protect their patients' information?

Quest also said it has stopped using AMCA for billing and that it was using "forensic experts" to examine the issue.
