Novocure said unauthorized access to certain information systems in mid-August exposed internal records of more than 1,400 U.S. patients. The oncology company activated its cybersecurity response plan, contained the incident and began an internal investigation. The exposed information included patient ID numbers, provider contact details and employee job titles and phone numbers; data from fewer than 50 patients in the western U.S. included additional identifying information. Novocure said its medical treatment devices were not accessed, all systems remain fully functional and the incident is not expected to have a material financial impact. The breach adds to a series of cyberattacks affecting healthcare companies, including Abbott, Stryker, Medtronic, Boston Scientific, Novo Nordisk and West Pharmaceutical Services.
