Medical device giant Boston Scientific has disclosed a cyberattack that it says is disrupting its IT systems and business applications across the globe.
Below are seven things to know about the incident.
—The attack occurred on Tuesday, and Boston Scientific notified the public on Wednesday. The company hasn’t disclosed whether data was stolen or whether ransomware was involved.
—The incident has knocked out systems Boston Scientific relies on to fill and ship customer orders. The devicemaker said the outage is limiting access to global IT systems and apps tied to day-to-day operations, and it has not set a timeline for getting everything back online.
—It’s unclear how the hacker gained access. Boston Scientific hasn’t identified or disclosed who is behind the attack, and no group has claimed responsibility for it yet.
—The disclosure hit Boston Scientific’s stock hard. The company’s shares fell 5-6% post-cyberattack. This comes as Boston Scientific has already lost nearly half its value this year amid disappointing demand for its Watchman heart implant and a weaker profit outlook.
—The full scope of the attack, including its operational and financial impact, remains unknown. Boston Scientific hasn’t yet determined whether it’s likely to have a material effect on the business.
—Boston Scientific activated its incident response plan and brought in third-party cybersecurity specialists to investigate and contain the threat. It also filed an 8k with the Securities and Exchange Commission and said it will continue to provide updates on its website when appropriate.
—Boston Scientific is now part of a growing list of medical device companies hit by major cyberattacks this year. In 2026, there have been similar incidents at Stryker, Medtronic and Abbott.
