US authorities believe Eastern European hackers are responsible for a cyber attack on the Utah Health Department (UHD) that exposed 24,000 Medicaid files.
The intrusion reportedly occurred on Friday, with the hackers targeting UHD's Medicaid claims files. The information contained in the claims included individuals' names, bank account details and social security numbers.
At the time of publishing, the UHD had not responded to V3's requests for comment on the breach.
According to Reuters, the intrusion is believed to have affected the claims of at least nine per cent of the 260,000 Utah Medicaid clients - though the exact number of those affected is unknown, with some claims containing information on multiple people.
"At this point, efforts are focused on determining the number and identity of individual clients who may have had their information compromised during the breach," Utah's Health and Technology Services departments told Reuters.
Suspicion fell on Eastern Europe after members of the state's Technology Services department traced a number of suspicious IP addresses to a number of countries in the region.
Medicaid is a US federal-state programme designed to help low income, disabled and elderly people with the cost of healthcare.
