  • BioReference Laboratories: 422,600 patients

The data of these companies were compromised after AMCA’s payment system was breached on August 1, 2018 and remained vulnerable till March 30, 2019.

What data was involved?

Although the compromised information varies for each victim company, but it includes some or all of the following:

  • Patient Name
  • Date of Birth
  • Address
  • Phone Number
  • Date of Service
  • Provider
  • Balance Information
  • Payment Card Information
  • Bank Account Information

How is the situation being addressed?

Meanwhile, General Frosh has also urged consumers to review their financial and medical accounts for suspicious activity.

“Massive data breaches like the one experienced by the AMCA are extremely alarming, especially considering the likelihood that personal, financial, and medical information may now be in the hands of thieves and scammers,” said General Frosh, CBS Baltimore reported.
