PORTAGE, MI — Some Stryker employees are still unable to work more than a week after a cyber attack disrupted the global company’s systems, an employee said.
The cyber attack occurred Wednesday, March 11. When employees arrived at facilities in Portage that day, they were told to head home until the company could address the incident. The incident affected other Stryker facilities and systems worldwide.
An employee confirmed to MLive that workers were told to stay home multiple days since the hack, including on Friday, March 20, nine days after the incident.
Stryker’s Portage facility, 1941 Stryker Way, is the global headquarters. The company manufactures medical devices.
The hack is suspected to be the work of an Iran-linked hacking group, according to reports.
The company told MLive last week that Stryker would pay employees for their regularly scheduled time, including for any hours they were unable to work due to closures. MLive has reached out for more details.
The hack was reported in media reports and Stryker later confirmed it was a “cybersecurity attack.”
After the company detected the “global disruption” to its Microsoft environment, Stryker executed an incident response plan and launched an investigation with the support of external advisors and cybersecurity experts.
“Importantly, the incident is contained to Stryker’s own internal Microsoft environment,” the company said. “There is no malware or ransomware detected. Our connected products are not impacted and are safe to use.”
Some of the managers’ phones were completely wiped, the worker told MLive.
The employee said they are upset about the work situation and also about how an overseas conflict is hitting home here in Michigan.
The employee spoke on the condition of anonymity, but provided MLive proof of their employment at Stryker.
The employee said they also understand the frustration of people who have lost their homes, their families and their quality of life due to the war, and why those people may feel the need to retaliate.
“I just don’t understand why everyday working people have to be affected on both sides,” the employee said previously, “when we didn’t make these decisions.”
Stryker reported $25.1 billion in global sales for 2025, Crain’s reports.
