Wisconsin Physicians Service Insurance Corporation (WPS)

A security vulnerability in the MOVEit software, developed by Progress Software and used by WPS to transfer files in the provision of services to CMS, led to unauthorized access of personal information. Between May 27 and May 31, 2023, personally identifiable information (PII) of Medicare beneficiaries—collected for managing Medicare claims and CMS audits of healthcare providers—was compromised, affecting up to 946,801 individuals. WPS discovered and reported the breach to CMS, initiating notifications to the impacted parties.
