Medical device manufacturer Boston Scientific has confirmed a cyberattack that has disrupted core business operations, including its ability to process and ship customer orders. The company disclosed the incident in a statement and in filings with the Securities and Exchange Commission after discovering the breach on Tuesday.

According to Boston Scientific, the incident “impacted access to certain operating systems and business applications,” directly affecting order processing and shipment capabilities. A company spokesperson declined to confirm whether ransomware was involved and said there is currently no timeline for full system restoration.

The attack triggered a network outage that has disrupted operations globally, forcing the company to bring in an outside cybersecurity firm to investigate and remediate the damage. Boston Scientific said it remains unclear how significant the financial impact will be. The company reported $5.4 billion in net sales for the second quarter of 2026, underscoring the scale of operations now affected.

Investors reportedly told CNBC they were informed that full system recovery could take weeks. As of Wednesday, no ransomware or extortion group had publicly claimed responsibility for the attack.

Part of a Broader Pattern in Medical Device Sector

Boston Scientific, known for producing pacemakers, stents, and other medical devices, joins a growing list of medical device manufacturers hit by disruptive cyberattacks this year.

  • Last month, Medtronic, the world’s largest medical device company, notified more than 3.8 million individuals that their data may have been exposed in an attack reportedly linked to a well known cybercrime group.
  • Earlier this year, Michigan-based Stryker was hit by an attack later claimed by a group connected to the Iranian government. That incident took weeks to resolve and, according to the FBI, had downstream effects on hospitals and medical facilities across the United States.

The recurring targeting of medical device manufacturers highlights the sector’s exposure to operational disruption from cyberattacks, particularly given the tight coupling between IT systems and physical supply chains for critical healthcare products. Boston Scientific has not indicated whether patient data was compromised in the incident.
