Following the incident, the CE blocked the attacker’s access to its information system, changed the system password, upgraded pertinent software, and hired third-parties to assist in responding to the incident and guarding against future incidents. The CE notified affected individuals, the media and HHS in accordance with the Breach Notification Rule. OCR reviewed the CE's relevant policies, procedures and documentation of its privacy and security safeguards as part of this investigation.
