Multiple reports say a wiper malware attack targeting Stryker, a U.S.-based medical technology company with a major operations hub in Ireland, has been claimed by an Iran-linked hacking group. Krebs on Security reports that a hacktivist group with links to Iran’s intelligence agencies claims responsibility for a data-wiping incident affecting Stryker. It also notes that Stryker tells staff to go home at its Ireland location, where more than 5,000 workers were sent home, while a voicemail message at Stryker’s main U.S. headquarters states the company is experiencing a building emergency. Infosecurity Magazine reports that a pro-Iran group called Handala claims a destructive wiper operation and says it wiped 200,000 systems. The accounts present the attacker’s claims and describe organizational disruptions, but they do not provide additional independent technical verification in the shared excerpts. Together, the reports indicate a cyber incident involving destructive malware claims from Iran-linked actors and operational impacts at Stryker facilities in both Ireland and the United States.
