Hacker group behind Stryker attack forced to 'reorganise' after key figures killed in military action

While it was initially believed that Stryker suffered a 'wiper' attack — in which the computer network is disabled or wiped out — cyber intelligence sources said this was not the case.

Irish intelligence officials believe the Iranian-backed hacker group behind the cyberattack on global med tech company Stryker, which has more than 5,000 employees in Ireland, is having to “reorganise” after two of its key figures were killed in US and Israeli military action.

Officials suspect that the Handala Hack group, and other hackers controlled by the Iranian clerical regime, will persist in cyberattacks across the world, including US corporations who have bases in Ireland.
