Iran hacking group claims attack on US medical company

An Iran-linked hacking group claims responsibility for a sweeping cyberattack on US medical technology giant Stryker, saying it wiped more than 200,000 systems and extracted 50 terabytes of data in retaliation for military strikes on Iran.

“Our major cyber operation has been executed with complete success,” Handala says in a statement, describing the attack as retaliation for what it calls “the brutal attack on the Minab school” and for “ongoing cyber assaults against the infrastructure of the Axis of Resistance.”

The group says it shut down Stryker offices in 79 countries and that all extracted data is “now in the hands of the free people of the world.” It issues an open warning to what it describes as “Zionist leaders and their lobbies,” adding: “This is only the beginning of a new chapter in cyber warfare.”

Stryker says in a statement it is “experiencing a global network disruption to our Microsoft environment as a result of a cyberattack. We have no indication of ransomware or malware and believe the incident is contained.”

Founded in Kalamazoo, Michigan, Stryker is a global medical device giant with some 56,000 employees and $25.12 billion in 2025 revenues, making everything from orthopedic implants and surgical instruments to hospital beds and robotic surgery systems.
