Stryker Corporation (NYSE:SYK) saw its shares decline 4% on Thursday after the company reported ongoing shipping interruptions tied to a cyber attack on its global network, following a 3.6% fall on Wednesday.
The medical technology firm said it is responding to an attack that targeted its Microsoft environment. Company statements emphasize that there is no indication of ransomware or malware involvement and that the issue appears to be contained within its internal Microsoft environment.
Stryker provided details on order handling amid the disruption. The company has visibility into orders that were entered prior to the incident and intends to ship those orders once communications between systems are restored. Orders received after the onset of the incident are under review. Stryker said it is actively working to restore its electronic ordering system.
On patient-facing technology, Stryker confirmed the Mako System used in hip, knee and shoulder procedures is not a connected device and remains safe for use. The company also stated that other products, including Vocera and LIFEPAK35, are fully safe to use.
To maintain service, Stryker said it has business continuity measures in place to continue supporting customers and partners. The company reassured stakeholders that it is safe to communicate with Stryker employees and sales representatives by email and phone.
Stryker described protections for portable media and local planning workflows. The company said it has implemented multiple layers of security for its flash drives, including encryption and automated quality checks. For procedures using the Mako System, Stryker indicated it can locally plan cases directly on the system for total and partial knees, and that representatives can hand carry CDs to the system without requiring network connectivity.
The company has not reported evidence of data-exfiltration tools or ransomware, and characterized the incident as contained to its internal Microsoft environment. Details on the timeline for full restoration of electronic ordering and system communications were not provided.
Summary
Stryker's stock fell after a cyber attack disrupted shipping and its electronic ordering systems.
