Highlighting the potential impact on global supply chains from the U.S.-Israel war against Iran, an Iran-linked group said it hacked the Stryker Corporation, which makes medical devices and is based in Michigan. Handala, a hacker group, said the attack caused “global disruption” to its systems, and was in retaliation for the bombing of the Minab school in Iran. The Guardian reports that the attack is seen as widening the Middle East conflict into the cyber realm.

The Iranian group claimed responsibility for the attack on the Stryker Corporation, which affected thousands of employees using the company’s Microsoft systems.

In a statement, Stryker said the attack is expected to continue to cause “disruptions and limitations of access to certain of the company’s information systems and business applications” and warned: “The timeline for a full restoration is not yet known.”

Stryker’s share price dropped about 3% on news of the attack. Lee Sult, chief investigator at cybersecurity firm, Binalyze, told the Guardian it was “the first drop of blood in the water,” as the Iran conflict spreads to U.S. cyber targets, and predicted “more shots are coming.” The same hacker group has already attacked Israeli cyber targets as Iran attempts to inflict economic disruption on its adversaries.

A statement posted to X on March 11, apparently from Handala, said: “We announce to the world that in retaliation for the brutal attack on the Minab school and in response to ongoing cyber assaults against the infrastructure of the Axis of Resistance, our major cyber operation has been executed with complete success.”

It called Stryker a “Zionist-rooted corporation” and claimed, without showing evidence, that it had wiped thousands of systems and mobile devices and extracted 50 terabytes of data.

Stryker said: “We have no indication of ransomware or malware and believe the incident is contained.
