Mosaic

The covered entity (CE), Mosaic, discovered multiple employee email accounts that had fallen victim to a phishing attack. The affected e-mail accounts contained the following types of protected health information (PHI): clients’ names, dates of birth, addresses, telephone numbers, government–issued identification numbers, medical record numbers, insurance identification numbers, payment information, Medicaid and Medicare numbers, and in some instances social security numbers. This breach affected approximately 3,857 individuals. The CE provided breach notification to HHS, affected individuals, and the media. The CE responded to the breach by blocking the IP address which was the source of the phishing scam, contacting the proper authorities to investigate possible criminal infractions, providing phishing scam awareness training, and changing its email practices. As a result of OCR’s investigation, the CE updated its HIPAA policies, created additional training material, and changed its training practices.
