Sept 1 (Reuters) – Oncology company Novocure said on Tuesday a cybersecurity incident involving unauthorized access to certain ​information systems in mid-August exposed ‌internal records of more than 1,400 U.S. patients.

The breach adds to a growing number of cyberattacks on the healthcare sector, including ‌medical ​device makers Abbott, Stryker ⁠Medtronic and Boston ⁠Scientific, drugmaker Novo Nordisk and drug-delivery equipment supplier West Pharmaceutical Services.

Here are some more details:

• Novocure said it activated ​its cybersecurity response plan, implemented containment measures and initiated an internal ⁠investigation of the ⁠event.

• The exposed data included ​internal company patient ID numbers and general ​contact information for healthcare providers the ‌company works with and for Novocure employees such as their job titles and phone numbers.

• Data for fewer ⁠than 50 other patients in the western U.S. that included additional identifying information was also ⁠exposed.

• The ‌company said access to ⁠its medical treatment devices was ​not ‌obtained, and that all its ​systems are ⁠fully functional.

• Novocure does not expect this cybersecurity incident to have a material impact on its financials.
