Iran-Linked Hackers Target US Firm Stryker Amid Israel Conflict

New York: Stryker, the largest medical device manufacturer in the United States, is still dealing with disruptions to its global network after a cyberattack that occurred last week. According to the leading news agency Reuters, an Iranian-linked hacker group has claimed responsibility for the incident.

Nearly five days after the breach, the company confirmed that some services remain affected as it works to restore operations. In an update posted on its official website on March 15, Stryker said it is “prioritizing restoration of systems that directly support customers, ordering and shipping”.

The company added that teams across its global facilities are coordinating to keep operations running while the recovery process continues. “We are working closely with our global manufacturing sites to manage operations and mitigate potential impacts, supported by our robust resiliency and business continuity plans,” the company said.

Stryker also reassured customers that the attack did not compromise its products or medical technologies. “All Stryker products across our global portfolio, including connected, digital, and life-saving technologies, remain safe to use. This event was contained to Stryker’s internal Microsoft environment, and as a result it did not affect any of our products-connected or otherwise,” the company said.

The company has not yet disclosed the full extent of the disruption or whether any sensitive data was accessed. Investigations into the attack are ongoing as Stryker works to restore normal operations. The incident also highlights the growing importance of advanced cybersecurity solutions, with companies increasingly turning to AI-driven tools to detect vulnerabilities and prevent such attacks in complex enterprise environments.

Below is the update from the company:

We wanted to provide you the latest update on the Stryker network disruption and progress on our restoration.  

Safety of our products

All Stryker products across our global portfolio, including connected, digital, and life-saving technologies, remain safe to use.

Stryker, much like any Fortune 300 company, has embedded policies and procedures for cybersecurity assurances for our products in the field. This process at Stryker provides additional assurances that no potential vulnerabilities or risk of exploitation related to our connected products exist.

Communicating with your Stryker Sales Representatives

It is completely safe for Stryker sales representatives to be onsite in hospitals and facilities. It is also safe for you to communicate by phone or e-mail with Stryker personnel. The event only affected Stryker’s internal Microsoft corporate environment. This was not a ransomware attack, and there is no evidence of malware deployed to our systems. The incident has been contained, and we are now in the restoration process, which is progressing steadily.   

Supply, ordering and shipping

We are working closely with our global manufacturing sites to manage operations and mitigate potential impacts, supported by our robust resiliency and business continuity plans. We are actively bringing our electronic ordering systems back online. In the meantime, your Stryker Sales Representatives will be working with you and your distributors directly in an effort to bring you replenishment product through manual ordering where that option exists. Orders placed prior to the disruption will be reconciled as systems are restored, and electronic orders placed during the disruption will process once systems are back online, and supply is flowing normally.  

Next steps

We are prioritizing restoration of systems that directly support customers, ordering and shipping. Our core transactional systems are already on a clear path to full recovery, and we will continue to provide updates as progress is made. There is nothing more important to us than the customers and patients we serve, and we are grateful for your continued support and partnership.
