The medical device maker says it detected an intrusion on August 25 that knocked out business systems and stopped some customer orders from going out.
Key points
- Boston Scientific detected a cyberattack on August 25, 2025 that disrupted IT systems worldwide.
- The intrusion stopped the company processing and shipping some customer orders.
- Boston Scientific disclosed the incident to the U.S. Securities and Exchange Commission but has not named the attacker or the method used.
- No ransomware gang has publicly claimed the breach.
- The Massachusetts firm employs 59,000 people across 127 countries and reported over $20 billion in 2025 revenue.
Medical device giant Boston Scientific has been hit by a cyberattack that knocked parts of its IT network offline and disrupted operations around the world.
The company spotted the intrusion on August 25 and confirmed the details in a filing with the U.S. Securities and Exchange Commission, the American financial regulator that requires public companies to disclose serious incidents to investors.
Certain operating systems and business applications went down, including the systems Boston Scientific uses to process and ship customer orders. Hospitals and clinics waiting on stents, catheters or defibrillators may see delays. The company hasn't said when everything will be back to normal.
What actually happened?
Someone broke into Boston Scientific's corporate network. The company detected it on August 25, activated its incident response plan, and brought in outside cybersecurity specialists to contain the damage and investigate.
Details are thin. The SEC filing doesn't name the attackers, describe how they got in, or say whether any patient or employee data was stolen. No ransomware group, criminals who lock a victim's files and demand a ransom to restore access, has publicly claimed responsibility. BleepingComputer first reported the disruption after the regulatory filing went live.
Who is Boston Scientific and why does this matter?
Boston Scientific is one of the world's largest makers of medical devices, the small pieces of hardware doctors use in minimally invasive procedures: heart stents, catheters, pacemakers, defibrillators and endoscopes.
The company is based in Massachusetts, employs 59,000 people, runs 13 manufacturing plants and sells into 127 countries. It reported over $20 billion in revenue in 2025.
When a supplier that size can't ship, the effects ripple into hospitals, surgical schedules and, eventually, patients. We reported a near-identical pattern with Nick Scali in August, where customers only learned about a network shutdown when their furniture never arrived. The medical supply chain carries higher stakes.
Should patients or hospital staff be worried?
Not immediately, but watch two things.
First, if a scheduled procedure relies on a specific Boston Scientific device, hospitals may need to reschedule or substitute. Ask the clinic directly rather than assuming.
Second, watch for phishing emails, fake messages designed to trick you into handing over passwords or clicking malicious links, that impersonate Boston Scientific or a hospital supplier. Attackers often piggyback on real news events. If a message asks for login details or urgent payment, verify by phone using a number you already trust.
What we know so far

| Restoration timeline | Unknown |
What is still unclear
The open questions are whether this is ransomware, whether records were taken, and how the attackers got in. Valid stolen credentials remain the most common entry point into large enterprises. Multi-factor authentication, MFA, which requires a second check such as a phone prompt beyond the password, closes that gap in many cases. Whether it would've helped here, we don't yet know.
Boston Scientific says the investigation is ongoing. Expect more detail in the company's next SEC filing.
