Medical technology company Stryker, which supplies products and services used by hospitals, reported a global disruption after a cyberattack. The company said the incident affected its Microsoft environment and that there was no indication of ransomware or malware.

What Stryker reported

Stryker announced the cyberattack on March 11, saying it believed the incident had been contained. The company did not report ransomware or malware involvement in its initial statement.

AHA monitoring hospital impact

John Riggi, AHA national advisor for cybersecurity and risk, said the association is actively exchanging information with the hospital field and the federal government to understand the threat and assess possible effects on hospital operations.

Riggi said there were no known direct impacts or disruptions to U.S. hospitals at the time of the report, but that situation could change as hospitals review services, technology, and supply chain dependencies linked to Stryker and as the duration of the attack continues.

Why hospitals are watching closely

Because Stryker supports hospitals with technology and products, any disruption to its systems may require health care organizations to examine internal workflows and vendor relationships. The AHA noted that the potential impact will depend on how hospitals use Stryker-related services and how long the incident lasts.

• Stryker said its Microsoft environment was impacted.
• The company reported no indication of ransomware or malware.
• Stryker believed the incident had been contained.
• The AHA said it was not aware of direct U.S. hospital disruption at the time.

Cybersecurity guidance and resources

The AHA directed members to its cybersecurity and risk resources for additional threat intelligence and information. Hospitals and health systems monitoring vendor-related cyber incidents may use those resources to stay informed as the situation develops.

In a health care environment where technology supply chains are tightly connected, even a contained incident can prompt careful review. For now, the known facts point to a global disruption at Stryker, with no confirmed direct effect on U.S. hospitals.
