Full breach record for Colorado Department of Health Care Policy and Financing →6 incidents on file

Colorado Department of Health Care Policy & Financing (HCPF) notified Delaware residents of a data event involving approximately 324 individuals. The incident stemmed from a vulnerability in Progress Software's MOVEit Transfer application, exploited by an unauthorized actor who accessed files managed by third-party vendor IBM. The breach exposed names, Social Security numbers, Medicaid/Medicare IDs, dates of birth, and medical/insurance information. HCPF launched an investigation, engaged forensic review, and provided 24 months of credit monitoring via Experian to affected Delaware residents. The investigation was ongoing as of the notice date of August 11, 2023.
