An anonymous reader quotes a report from TechCrunch: Millions of Americans had their sensitive medical and health information stolen after hackers exploiting a zero-day vulnerability in the widely used MOVEit file transfer software raided systems operated by tech giant IBM. Colorado’s Department of Health Care Policy and Financing (HCPF), which is responsible for administering Colorado’s Medicaid program, confirmed on Friday that it had fallen victim to the MOVEit mass-hacks, exposing the data of more than four million patients.
In a data breach notification (PDF) to those affected, Colorado’s HCPF said that the data was compromised because IBM, one of the state’s vendors, “uses the MOVEit application to move HCPF data files in the normal course of business.” The letter states that while no HCPF or Colorado state government systems were affected by this issue, “certain HCPF files on the MOVEit application used by IBM were accessed by the unauthorized actor.” These files include patients’ full names, dates of birth, home addresses, Social Security numbers, Medicaid and Medicare ID numbers, income information, clinical and medical data including lab results and medication, and health insurance information. HCPF says about 4.1 million individuals are affected.
IBM has yet to publicly confirm that it was affected by the MOVEit mass-hacks, and an IBM spokesperson did not respond to a request for comment by TechCrunch. The breach of IBM’s MOVEit systems also impacted Missouri’s Department of Social Services (DSS), though the number of affected individuals is not yet known. More than six million people live in Missouri state. In a data breach notification posted last week, Missouri’s DSS said: “IBM is a vendor that provides services to DSS, the state agency that provides Medicaid services to eligible Missourians. The data vulnerability did not directly impact any DSS systems, but impacted data belonging to DSS.” DSS says that the data accessed may include an individual’s name, department client number, date of birth, possible benefit eligibility status or coverage, and medical claims information.
