Boston Scientific, a U.S. medical device manufacturer, reported a cyberattack that is causing a global disruption to its operations, according to a regulatory filing on August 26, 2026. The Massachusetts-based company, known for producing implanted devices such as pacemakers and defibrillators, stated in a filing with the U.S. Securities and Exchange Commission that it began experiencing disruptions and limitations of access to its IT systems and business applications on August 25, 2026.
The company indicated that the cyberattack has affected its ability to ship and process orders. However, it has not clarified whether the disruption impacts customers with medical devices and implants. Boston Scientific spokesperson Chanel Hastings provided the company’s public statement but did not comment on potential effects on patients or the nature of the incident.
Boston Scientific serves approximately 48 million patients annually, according to its website. The company noted that its investigation into the cyberattack is ongoing, and it has not provided a timeline for restoring its systems.
Local media in Ireland reported that thousands of employees at Boston Scientific’s Cork campus were sent home on August 25 after network communications were disrupted. This incident follows a series of cyberattacks on health technology companies this year, including Abbott Laboratories and Medtronic. Earlier in 2026, Iranian-backed hackers were linked to a cyberattack on Stryker, another U.S. medical device maker, which allowed them to remotely wipe devices across its Windows network.
Public internet records indicate that Boston Scientific primarily relies on Microsoft and Amazon Web Services for its corporate infrastructure.
