A cyberattack during Thanksgiving week targeted the Fred Hutchinson Cancer Centre, but most of the incident's specifics are still unknown. Unlike the health care system's research network, Fred Hutch teams observed some unauthorised activity on specific areas of the clinical network. Although the nature of the data at risk is still unknown to the investigators, the corporation claimed that patient information may be included in the clinical network. The hospital stated that the clinical and research networks are still distinct and that the security incident did not affect the research side.
