Boston Scientific Operations Hit in Attack

September 29, 2026

INCIDENT

Most of manufacturing is back up and running after a cyberattack against Marlbourgh, Massachusetts-based medical device maker Boston Scientific Corporation that is “likely to have a material impact on the company’s results of operations for the third quarter and full year 2026.”
In a new 8-K report filed September 7 with the Securities and Exchange Commission (SEC), the beleaguered company said it identified a cybersecurity incident that affected certain of its information technology systems and resulted in a global disruption to the company’s operations.
Upon detection, the company activated its incident response protocols, and since then has been working, with the assistance of third-party cybersecurity experts, to investigate, assess and contain the impact of the incident and to restore operations.
