12 Million Affected In The Quest Diagnostics Data Breach

Quest Data Breach: Is Your Information Compromised?

Many of you will likely know of and use the services of Quest Diagnostics, one of the biggest blood testing providers in the country. It should be noted, though, that the company gave a serious warning on Monday that nearly 12 million of its customers may have had personal, financial and medical information breached due to an issue with one of its vendors. Here’s what we know about the Quest Diagnostics Data Breach.

In a recent securities regulations filing, Quest stated that the company was notified that between Aug. 1, 2018, and March 30, 2019, someone had unauthorized access to the systems of AMCA, a billing collections vendor.

(The) information on AMCA’s affected system included financial information (e.g., credit card numbers and bank account information), medical information and other personal information (e.g., Social Security Numbers),” Quest said in its filing.

Though consumers broad medical information may have been compromised, AMCA never had access to actual lab test results, and therefore that data could not be impacted.

Within this premise, however, we must also make note of the fact that even though it is uncertain whether customer’s sensitive, HIPAA protected information was compromised or not, the sole fact that this type of data breach is able to occur, and cyber-criminals are easily granted access to your medical account information, is quite jarring. This process makes it all the more likely that your private medical information has either already been, or will eventually be shared, on the “dark web.”

But wait! There’s more! We don’t mean to frighten you further, but in looking at the charges within the complaint, and taking into account the frequency in which they occurred, cross-referencing this data with Quest Diagnostics’ publicly available fee schedules, these Cyber-Criminals will not have to expend much effort to know which tests were performed on the affected class members.

Now, in matching these charges with tests for rare genetic disorders, diabetes, or more serious conditions, this medical information may very well end up for sale in the darkest corners of the internet, and used for heinous purposes. In short, this Quest Data Breach can be more of a sting that previously disclosed by the company.
