Overview
- Luminis Health alerted state officials after technology problems on August 31 and posted on September 1 that it was responding to a cybersecurity incident that left certain systems unavailable.
- Anne Arundel Medical Center canceled treatments and rerouted patients to other hospitals as the outage affected scheduling, access to MyChart and some clinical services.
- Individual patients reported delayed care, including at least one cancer patient whose radiation or chemotherapy session was postponed and not yet rescheduled because systems were down.
- Luminis has launched an investigation with its legal team and third‑party cybersecurity firms and says it will notify individuals if the inquiry finds that protected health information was exposed; multiple Maryland agencies have met with system leadership to assess needs.
- Cybersecurity experts warned that recent attacks can be more automated and sometimes involve insider help, raising concerns about rising risk to hospitals and potential second‑order effects such as longer patient delays and increased pressure on nearby health systems.
