Nearly 1M Medicare beneficiaries potentially affected after data breach

Nearly 1 million Medicare beneficiaries are being warned that their personal information may have been compromised in a cybersecurity incident last year.

The Centers for Medicare & Medicaid Services (CMS) and Wisconsin Physicians Service Insurance Corporation (WPS), the contractor that utilized the affected MOVEit software, said last week that 946,801 people on Medicare were notified that they may have had "protected health information or other personally identifiable information" compromised.
