Stryker Cyberattack claims surfaced Wednesday after a hacking group linked to Iran said it disrupted the network of a major U.S. medical device manufacturer, raising concerns across the healthcare sector.
Michigan-based Stryker Corporation confirmed it is dealing with a “global network disruption” affecting its Microsoft-based systems following a cyber incident. The company said the attack impacted its digital environment but noted there was no evidence of ransomware or malware so far.
Stryker added that its teams are investigating the breach while implementing contingency plans to keep services running. The firm supplies medical equipment used by hospitals worldwide, including defibrillators, surgical tools, and ambulance stretchers, supporting healthcare providers that treat more than 150 million patients annually.
The cyberattack reportedly affected systems beyond the United States. Local media in Ireland said some of the company’s computers there were also disrupted during the incident.
It remains unclear whether the Stryker cyberattack has affected deliveries or operations at hospitals. However, cybersecurity specialists in the healthcare sector said they are closely monitoring the situation for possible ripple effects.
The hacking group claiming responsibility said the attack was carried out in retaliation for recent military actions against Iran. The group referenced a missile strike on an elementary school in Iran that Iranian state media said killed at least 168 children, an incident currently under investigation by the United States Department of Defense.
Security analysts note the Stryker cyberattack could be among the first major cyber operations linked to pro-Iran hackers targeting U.S. infrastructure since the United States and Israel began bombing Iran last month.
Experts say healthcare networks remain particularly vulnerable because of their complex digital systems and reliance on connected devices. Cybersecurity specialist Joshua Corman warned that geopolitical tensions are increasing the risk of cyberattacks from nation-state actors.
Following reports of the breach, Stryker’s stock dropped more than 3%, reflecting investor concern about the potential operational and reputational impact.
Authorities and cybersecurity firms are continuing to analyze the incident as part of wider monitoring for retaliatory cyber activity linked to escalating Middle East tensions.
