Stryker Hit by Suspected Iran-Linked Cyberattack, Causing Global Outages
Medical technology giant Stryker suffered a global system outage on March 10, 2025, following a suspected cyberattack linked to an Iran-backed hacking group. The incident began shortly after midnight on the U.S. East Coast, disrupting operations across the company’s network.
According to reports, remote devices running Microsoft Windows including laptops and mobile devices connected to Stryker’s systems were wiped, rendering them inoperable. Employees and contractors reported seeing the logo of Handala, a pro-Palestinian hacking group with alleged ties to Iran, on login screens, though Reuters could not independently verify the claim.
The attack triggered a 3% drop in Stryker’s stock price after The Wall Street Journal first reported the breach. The company has not yet issued an official response to requests for comment.
Stryker, a major supplier of medical equipment, operates globally, with facilities including a plant in Carrigtwohill, Ireland. The full extent of the disruption and potential data compromise remains unclear.
