Medical device manufacturer Boston Scientific confirmed on Wednesday it is experiencing a cyberattack that has disrupted global operations, including systems used to process and ship customer orders. The company disclosed the incident in a Securities and Exchange Commission (SEC) filing, stating it was discovered on Tuesday and continues to affect business functions.
The attack has limited access to certain information systems and business applications, the filing said, though the company did not specify the nature of the breach or whether customer data was compromised. Boston Scientific has engaged external cybersecurity experts to investigate the incident and contain the threat. The company noted that the timeline for full restoration remains unknown as it works to restore affected functions.
Shares of Boston Scientific fell up to 6% in early trading following the disclosure, adding to a year-to-date decline of nearly 50% amid broader market pressures and a weak first-quarter profit forecast. The company produces medical devices such as pacemakers, stents, and cancer care technologies.
Cybersecurity Context
The healthcare sector remains a primary target for cybercriminals, according to research from BlackFog, a cybersecurity firm. In 2025, the industry accounted for 22% of all disclosed ransomware attacks, the highest of any sector. The attack on Boston Scientific follows a pattern of increasing cyber threats targeting medical device manufacturers, which handle sensitive patient and operational data.
Company Response
In its filing, Boston Scientific emphasized that while the incident has caused disruptions to order processing and shipping, the company is prioritizing restoration efforts and security containment. The company did not provide additional details on the scope of the attack or potential customer impact beyond operational disruptions.
Market Impact
The cyber incident coincides with broader challenges for Boston Scientific, including a sharp decline in share value this year. The company’s stock has been under pressure since its first-quarter earnings report, which included a cautious profit forecast. Analysts and investors are closely monitoring the situation as the company works to resolve the technical issues and restore normal operations.
