Cyber intrusion forces prolonged disruption of Groupe santé CHC online patient and physician services

On November 18, 2022, Groupe santé CHC in Belgium detected suspicious activity indicating an attempted cyber intrusion into its healthcare IT environment. The organization immediately disconnected external network connections to contain the threat. This protective isolation made its public website and general-practitioner portal unavailable and prevented patients from scheduling medical appointments online, requiring telephone-based arrangements instead. Contemporary reporting indicated that externally accessible computer services remained impaired months later, including in March 2023. The healthcare organization stated that its internal networks and clinical applications continued functioning and that patient care remained available. The documented material consequence was prolonged degradation of patient-access and clinical coordination services rather than a confirmed interruption of medical treatment.
