OCR description

MultiCare Health System, the covered entity (CE), reported that due to a phishing attack a hacker gained access to an employee’s email access credentials for approximately 3 days. The breach affected the protected health information (PHI) of 1,249 individuals and included names, dates of birth, dates of service, diagnoses, medical record numbers, and descriptions of treatment. The CE provided breach notification to HHS, affected individuals and the media. Following the breach, the CE updated its policies and procedures addressing phishing emails, implemented technical security safeguards to reduce the risk of malware infection and hacking, and retrained all employees on its updated policies and procedures. OCR provided the CE with comprehensive technical assistance regarding its obligations under the Security Rule to conduct a thorough security risk analysis and implement a corresponding risk management/mitigation plan. OCR also provided an explanation of the requirements of the Security Rule for the CE to use in future compliance efforts. OCR obtained documented assurances that the CE implemented the corrective actions listed above.
