CommonSpirit Health and its affiliated entities (“CommonSpirit”) take the protection and proper use of personal information very seriously. Regrettably, CommonSpirit experienced a ransomware event that impacted some personal information. While CommonSpirit has no evidence of misuse of the personal information as a result of the incident, this notice is to explain the incident, our response to it, and steps one can take to protect personal information.
CommonSpirit Health is the parent organization to Catholic Health Initiatives and Dignity Health facilities. CommonSpirit Health also is or has been associated with Centura Health and MercyOne (Iowa). Not all CommonSpirit Health locations were involved in this incident. A list of locations whose data may have been involved can be found here.
On October 2, 2022, CommonSpirit detected a ransomware attack on its IT network. CommonSpirit immediately took steps to secure the network, which included proactively taking some systems offline, and began an investigation with the assistance of an external forensics vendor. The investigation determined that an unauthorized third party gained access to the network between September 16, 2022 and October 3, 2022. While the unauthorized third party did not retrieve data directly from CommonSpirit’s Electronic Medical Records systems, during that time, the unauthorized third party obtained copies of some of the data on our systems, including files from two file share servers that contained some individuals’ information. CommonSpirit had used the data on the file share servers in performing various operational functions, and some of the data dates back several years. With respect to the data on the file share servers, determining what and whose data was impacted has required a detailed and time-consuming review of each individual file on each file server to identify the specific individuals whose information may have been impacted, and the type of information associated with each such individual. The initial phase of this part of the investigation was completed on February 21, 2023. Once this component of the review concluded, we worked to identify, when possible, the current and past CommonSpirit location(s) associated with the data. We then worked to identify accurate address information to provide notice to potentially affected individuals and only recently completed these efforts.
What information was involved.
The individuals included in this notification are those whose information was identified on the file share servers.
The information in the files included demographics such as name, address, date of birth, phone number(s), email address, as well as medical information such as dates of service, medical record number, healthcare provider’s name, diagnosis/treatment information, medical billing/claims information, patient’s facility associated account/encounter number, and health insurance information. For a small number of individuals, Social Security Number was also involved.
What we are doing.
Upon discovering the ransomware attack, CommonSpirit quickly mobilized to protect its systems, contain the incident, begin an investigation, and maintain continuity of care. In addition, CommonSpirit notified law enforcement. Once secured, systems were returned to the network with additional security and monitoring tools. CommonSpirit began notifying individuals impacted by the file share server data by US. Mail on April 6, 2023.
What you can do.
Though CommonSpirit has no evidence that the information has been misused as a result of this event, it is always prudent to review health care statements for accuracy and report any services or charges that were not incurred to the provider or insurance carrier.
