An Iranian-linked hacking group known as Handala has carried out a cyberattack on U.S. medical equipment company Stryker, shutting down technology operations across its global offices. The attack disrupted operations for thousands of employees who were unable to access company systems.

Why it matters
The cyberattack on Stryker is the latest in a series of high-profile cyber operations claimed by Iranian-linked groups, which have become increasingly disruptive in recent years. It underscores Iran's willingness to use cyber warfare as a tool to retaliate against perceived adversaries, even targeting major U.S. companies. The incident also raises concerns about the vulnerability of critical infrastructure and the need for robust cybersecurity measures.
The details
According to reports, the Iranian-linked cyber group Handala claimed responsibility for the attack on Stryker, stating it was 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.' The attack resulted in Stryker employees being unable to access company systems, including remote devices running Microsoft Windows. Stryker has said it is working to restore systems and operations as quickly as possible.
