Quest Diagnostics Data Breach Affects 12 Million People
Quest Diagnostics has suffered a massive data breach and it implicates more than 12 million patient records.
According to a news report, the information leaked includes personal, patient records, financial data, Social Security numbers and other medical information.
In its press release, Quest Diagnostics said the American Medical Collection Agency (AMCA), a billing collections service provider, had informed them that an unauthorized user had access to AMCA’s system containing personal information AMCA received from various entities, including from Quest.
AMCA first notified Quest and Optum360 on May 14, 2019 of potential unauthorized activity on AMCA’s web payment page. On May 31, 2019, AMCA notified Quest and Optum360 that the data on AMCA’s affected system included information regarding approximately 11.9 million Quest patients. AMCA has not yet provided Quest or Optum360 detailed or complete information about the AMCA data security incident, including which information of which individuals may have been affected; therefore, Quest has not been able to verify the accuracy of the information received from AMCA yet.
