A data breach at the Utah Department of Technology Services (DTS), which operates computer servers that store Medicaid claims data for the Utah Department of Health (UDH), appears to have affected more consumers than first estimated. Late last week, the DTS reported that about 181,000 Medicaid and Children's Health Insurance Plan (CHIP) recipients were affected. About 25,096 people of the 181k total had their Social Security numbers exposed/stolen.
Yesterday, the UDH disclosed a greater number of breach victims: an additional 255,000 additional victims had that Social Security numbers stolen, and an additional 350,000 had lesser personal information exposed/stolen. So, the total count is now 780,000 breach victims:
Medicaid claims typically include patients' names, addresses, birth dates, Social Security numbers, physician’s names, national provider identifiers, addresses, tax identification numbers, and billing codes for medical procedures. The initial breach estimate was 24,000 records exposed/stolen. The breach investigation is still ongoing. UDH disclosed in a press release:
"DTS servers have multi-layered security systems that include many controls, including: perimeter security, network security, identity management, application security, and data security. In this particular incident, a configuration error occurred at the authentication level, allowing the hacker to circumvent the security system. DTS has processes in place to ensure the state's data is secured, but this particular server was not configured according to normal procedure. DTS has identified where the breakdown occurred and has implemented new processes to ensure this type of breach will not happen again..."
The UDH is notifying all breach victims via a breach letter, but with a priority of first notifying the consumers whose Social Security numbers were exposed. These breach letters offer one year of free credit monitoring services. Other breach victims will receive a slightly different notice with information about how to further protect themselves. People with online access via the My Case web portal, were given breach notices both online at the web site and via e-mail.
