Uh oh. Quest Diagnostics has announced a huge data breach that could affect almost 12 million of its patients, according to NBC 10 Philadelphia.

Quest, one of the largest companies in the United States for medical blood testing, revealed that an issue with one of its vendors, a billing collections agency, left your personal, financial, and medical information vulnerable, if you had services between August 1, 2018 and March 30, 2019. Fantastic. Ugh.

Quest went on to say that the "issue with one of its vendors" means someone had unauthorized access to their billing systems, which means your credit card number, bank account number, social security number, may have been accessed.

If you want to feel a little bit better, Quest did say that while they had access to your personal and financial information, the billing company did not have access to your lab results, so that data of yours is safe.

In a statement, the firm representing Quest's billing agency, American Medical Collection System said, "Upon receiving information from a security compliance firm that works with credit card companies of a possible security compromise, we conducted an internal review, and then took down our web payments page. We hired a third-party external forensics firm to investigate any potential security breach in our systems, migrated our web payments portal services to a third-party vendor, and retained additional experts to advise on, and implement, steps to increase our systems’ security. We have also advised law enforcement of this incident. We remain committed to our system’s security, data privacy, and the protection of personal information."
