A data breach at a third-party provider has potentially exposed the private medical information of patients at Northwestern Memorial HealthCare (NMHC) providers.
Unknown actors gained unauthorized access to a database owned by Elekta, which provides a cloud-based platform that handles legally-required cancer reporting to the State of Illinois.
In a security advisory, the healthcare provider, based in Chicago, said that the attackers made a copy of the datasets, which include patient names, dates of birth, Social Security numbers, health insurance information, and medical record numbers.
The database also contained clinical information related to cancer treatment, including medical histories, physician names, dates of service, treatment plans, diagnoses, and/or prescription information.
