The covered entity’s (CE) electronic medical records (EMR) system and backup computer server were affected by ransomware. The breach included the protected health information (PHI) of 4,000 individuals and included names, as well as clinical information. The CE provided breach notification to HHS, affected individuals, and the media. Following the breach, the CE upgraded its EMR system to a cloud-based, encrypted EMR system with additional security features, and implemented additional antiviral protections. As a result of OCR’s investigation, the CE completed a risk analysis, developed a risk management plan, and revised its HIPAA policies and procedures to ensure that they are tailored to the CE’s needs.
