Boston Scientific says cyberattack disrupted operations globally

Medical technology giant Boston Scientific has confirmed a cyberattack that has caused global operational disruptions. The Massachusetts-based company, a major manufacturer of medical devices such as stents, pacemakers, and endoscopes, detected the intrusion on August 25.

The incident led to a network outage, impacting access to various operating systems and business applications. Crucially, the company's ability to process and ship customer orders has been affected, a disruption that is expected to continue. Boston Scientific, which reported over $20 billion in revenue in 2025 and operates in 127 countries with 59,000 employees, stated that the timeline for full restoration of affected systems is currently unknown.

Upon discovering the attack, Boston Scientific initiated its incident response protocols and engaged external cybersecurity experts to assist with investigation and containment efforts. The company is working to determine the full nature, scope, and potential operational or financial consequences of the incident.

In its disclosure to the U.S. Securities and Exchange Commission (SEC), Boston Scientific did not provide details regarding the type of cyberattack, the identity of the attacker, the initial access method, or whether any data was exposed or stolen. As of the latest reports, no ransomware or data extortion groups have publicly claimed responsibility for the breach.
