Cancer treatment and research center City of Hope is warning that a data breach exposed the sensitive information of over 820,000 patients.
City of Hope is a National Cancer Institute (NCI)-designated comprehensive cancer center providing treatment for cancer, diabetes, and other life-threatening diseases. The organization is headquartered in Duarte, California, and operates oncology clinics across the US.
Earlier this week, the healthcare organization published a notice of a data security incident on its site, informing that it suffered a security breach between September and October last year.
"On or about October 13, 2023, City of Hope became aware of suspicious activity on a subset of its systems and immediately instituted mitigation measures to minimize any disruption to its operations,"
reads the notice.
"City of Hope launched an investigation into the nature and scope of the incident with the assistance of a leading cybersecurity firm, which determined that an unauthorized third party accessed a subset of our systems and obtained copies of some files between September 19, 2023, and October 12, 2023."
