Stryker: Suspected Iranian cyberattack hits Stryker, disrupting systems across medical device company

Iran-Linked Cyberattack Disrupts Stryker, Global Medical Device Manufacturer

A suspected cyberattack attributed to an Iran-affiliated hacking group has disrupted operations at Stryker, a Michigan-based global medical device manufacturer. The attack, reported on June 10, 2024, caused widespread system outages across the company’s network, affecting facilities including its Portage, Michigan headquarters.

Employees and contractors reported seeing the hacking group’s logo appear on company devices during the incident. The group claimed responsibility in a post on X (formerly Twitter), citing retaliation for an alleged attack on an Iranian school in Minab. Stryker confirmed the disruption and is working to restore affected systems.

The incident highlights growing cybersecurity risks in the healthcare and medical device sectors, where operational disruptions can have cascading effects on patient care and supply chains. No details on data breaches or patient impact have been disclosed.
