CISA launches investigation into Stryker cyberattack

A pro‑Tehran hacking group, reported as Handala, allegedly carried out a global cyberattack against Stryker that wiped employee phones and disrupted access to corporate Microsoft systems; CISA has launched an investigation and Stryker says the incident is contained but causing ongoing operational disruption. The article frames the event as possible Iranian cyber retaliation tied to the U.S.–Israel conflict, references prior similar disruptive activity from pro‑Iran groups, and notes limited public technical detail and indicators at this time.
