(March 19): The US government is warning businesses to secure their corporate accounts within a popular Microsoft Corp management tool, following a cyberattack on Stryker Corp last week.
The Cybersecurity and Infrastructure Security Agency (CISA) issued an advisory late on Wednesday urging companies to follow Microsoft’s recommendations for fortifying Intune, a tool that manages employee and administrative account access across an organisation.
“The CISA is aware of malicious cyber activity targeting end-point management systems of US organisations based on the March 11, 2026, cyberattack against US-based medical technology firm Stryker Corporation, which affected their Microsoft environment,” the bulletin read. “To defend against similar malicious cyber activity, CISA urges organisations to harden end-point management system configurations using the recommendations and resources provided in this alert.”
The pro-Iranian group Handala claimed responsibility for the attack, which knocked some of the surgical robot and tool maker’s networks offline and affected shipping. Some surgeries have been delayed as a result.
The Wall Street Journal previously reported that the hackers broke into Stryker’s Intune dashboard to create administrative accounts and effectively control access to Stryker’s systems.
