What the Stryker Cyberattack Tells Us About Network Resilience Right Now

By Kenneth Florenz, Sr. Director of Enterprise Solutions at Lightpath

On Wednesday, Michigan-based medical technology company Stryker disclosed a cyberattack that knocked out systems across its global offices — phones went dark, laptops were wiped, and thousands of employees lost access to the tools they use to do their jobs. The Iran-linked group Handala claimed responsibility, calling it retaliation for a missile strike on an Iranian school. According to investigators and cybersecurity researchers, this appears to be the first significant cyberattack by an Iran-linked actor targeting a major U.S. company since the current conflict escalated.

The story made headlines because of the geopolitical context. But the more important question for IT and operations leaders isn't political. It's this: When connectivity disappears, what breaks first in your organization?

It Wasn't Ransomware. That's the Point.

When most people hear "cyberattack," they picture ransomware — criminals locking files and demanding payment. Stryker confirmed there was no ransomware, no malware in the traditional sense. What happened instead was a destructive wiper attack: devices were remotely wiped, data was deleted, systems were shut down across 79 countries.

The goal wasn't money. It was disruption.

That distinction matters. Wiper attacks aren't designed to be reversed. They don't end with a negotiation or a decryption key. They end when you've rebuilt your infrastructure from scratch — or when you had the redundancy in place before the attack hit.

The Operational Reality Most Leaders Miss

Here's what a major network disruption actually looks like from the inside, and it maps almost exactly to what Stryker employees described: phones stop working. Collaboration platforms go offline. Remote staff can't reach company systems. Supply chains stall. In a medical technology company, that means hospitals trying to determine whether to physically disconnect equipment — as reportedly happened in Maryland, where Stryker's Lifenet ECG transmission system went non-functional across most of the state.

Now map that to your organization:

• If your internet-facing infrastructure went offline right now, how long before phone systems — especially those running on SIP trunks or cloud-based UCaaS — stop working?
• How long before your ERP, your customer portal, your remote workforce lose connectivity?
• Who owns the response plan, and what's the first call they make?

These aren't hypothetical questions. They're the questions Stryker's leadership team was answering in real time on Wednesday.

Why DDoS and Disruption Often Travel Together

The Stryker incident appears to have been a wiper attack rather than a volumetric DDoS. But in many high-profile nation-state operations, distributed denial of service is part of the same playbook — used to overwhelm VPN and remote access systems, distract IT teams, mask deeper intrusion activity, or simply create visible operational chaos that sends a message.

Geopolitically motivated attacks don't follow the patterns of financially motivated crime. The objective isn't to extract value. It's to disrupt, demoralize, and demonstrate capability. That changes how organizations need to think about protection. On-premises firewalls are designed for the former. Carrier-level filtering, always-on monitoring, and redundant internet paths address the latter.

What Resilience Actually Looks Like

Organizations that handle disruption well — whether from a nation-state actor, a software failure, or a cable cut — tend to share a few characteristics:

They have upstream traffic filtering that doesn't depend on their own infrastructure being operational. They have redundant internet paths so a single point of failure doesn't take everything down. They have incident response plans that name the person who makes the first call, not just the team that eventually responds. And their leadership has visibility into network health before something goes wrong, not after.

The Takeaway

The Stryker attack is still developing. The full scope of the damage — operational, financial, reputational — won't be known for weeks. But the event itself is already a clear signal: organizations running critical infrastructure, healthcare supply chains, and public services are targets in a way they weren't five years ago. The barrier to launching a destructive cyberattack has dropped. Dependence on cloud connectivity and distributed networks has gone up.

That gap is where resilience lives — or doesn't.

The question worth asking today isn't whether your security team knows about Handala. It's whether your organization could absorb a global network disruption and keep operating. If you don't know the answer, that's the place to start.
