Boston Scientific, a major Massachusetts-based medical device manufacturer, disclosed that a cyberattack disrupted its operations globally, impacting the company鈥檚 ability to process and ship customer orders. The company detected the incident on August 25 and announced that the attack caused a network outage affecting access to certain operating systems and business applications. Boston Scientific said the disruption has already caused, and is expected to continue to cause, limitations on operations that support order fulfillment. The company is working to restore affected functions but stated that the timeline for a full restoration is not yet known.
Upon identifying the intrusion, Boston Scientific activated its incident response procedures and brought in external cybersecurity experts to investigate the scope of the impact and assist with containment efforts. The company鈥檚 announcement did not specify the type of cyberattack, the identity of the attacker, or the method of initial access. It also did not disclose whether any data was exposed or stolen during the incident. Boston Scientific said its investigation is ongoing to determine the nature, scope, and potential operational or financial consequences of the breach.
The company filed a disclosure with the U.S. Securities and Exchange Commission (SEC) to report the attack, but that filing similarly lacked details about the threat actor or any data compromise. As of the time of the report, no ransomware or data extortion group had publicly claimed responsibility for the breach. Boston Scientific did not immediately respond to requests for additional information.
Boston Scientific is one of the world鈥檚 largest medical device manufacturers, employing 59,000 people and operating 13 manufacturing facilities. The company has a presence in 127 countries and generated more than $20 billion in annual revenue in 2025. Its products include stents, catheters, pacemakers, defibrillators, and endoscopes used in minimally invasive procedures. Given its role in the U.S. healthcare supply chain, the disruption could affect hospitals and clinics that rely on its devices, though the company has not detailed the extent of shipment delays.
The operational impact is centered on the company鈥檚 ability to move products to customers, which is a critical function for a manufacturer of medical devices. Boston Scientific noted that access to certain business applications supporting its operations has been limited, but it has not specified which systems remain offline. The company emphasized that it is working diligently to restore affected functions, but offered no estimate for when systems would be fully operational.
This incident adds to a pattern of cyberattacks targeting large U.S.-based medical technology firms, which are attractive to attackers due to their critical role in healthcare delivery. The SEC filing ensures federal oversight and investor awareness, but the lack of disclosed technical details leaves questions about the attack vector unanswered. For now, Boston Scientific is focused on containment and recovery, with customers and regulators awaiting further updates on the restoration timeline.
