However, fewer than 50 patients had additional identifying information exposed. Novocure confirmed that no access to medical treatment devices was obtained, and their operational capabilities remain intact. The company is investigating the incident and will notify affected individuals as required. This incident is part of a troubling trend of cyberattacks targeting healthcare companies, with several similar breaches reported in recent months.
