Is Your Shop’s Scan Tool a Security Risk? Here’s What to Know

Listen to the episode here

Let’s be real—most shop owners are too slammed to worry about "cybersecurity." Between getting cars in and out, managing techs, ordering parts, and dealing with customers who Google everything, it’s hard enough just to stay afloat.

But here's the kicker:
Your shop is already connected to the internet—and that means it’s already a target.

On a recent episode of the LeadFoot Automotive Podcast, we sat down with Donny Seyfer, Executive Officer at NASTF (National Automotive Service Task Force), and what we learned should wake up every shop owner in the country.

Why Every Shop Owner Needs to Start Thinking Like a Bank

Donny’s no stranger to wrenching. He’s a third-gen tech, hot rodder, and shop owner who now leads one of the most important organizations in the industry when it comes to diagnostic tool access, service information, and security protocols.

And here's what he's seeing:

• Scan tools are being stolen or hacked to gain access to vehicles.

• Shops are still using outdated systems like Windows 7, which are no longer secure.

• Hackers are now targeting vehicle data and key programming systems.

• And yes, your technicians’ phones on the shop Wi-Fi could be a weak point.

This isn’t theory—it’s already happening. And the people doing it aren’t punks with a crowbar. These are organized, tech-savvy criminals who know exactly what they’re after.

Donny even shared how locksmiths are getting ambushed on the job, just for the tools they carry. Thieves are using stolen diagnostics to create keys, bypass immobilizers, and resell vehicles fast.

How Cybersecurity in the Bay Can Actually Make You More Money

Let’s say you don’t care about all the tech talk. Fair enough.

But here’s what you should care about:

• Not losing thousands replacing stolen tools or dealing with insurance claims.

• Avoiding downtime from a ransomware attack or infected scan tool.

• Being the shop in town that can handle late-model vehicles, including ADAS calibrations and modern security systems.

• Attracting younger techs who already understand technology and want to work somewhere that’s not stuck in the stone age.
  

Donny said it best:

“The enemy is already in your shop. We’re just trying to help you get him out.”

And he means that literally. If you’re not separating your shop network, your scan tools, and your customer Wi-Fi—you’re making it way too easy for someone to walk in the digital front door.

What You Can Do Today to Get Ahead (and Stress Less)

Look—we’re not saying you have to turn into a hacker-hunting superhero overnight. But you do need to start taking this stuff seriously.

Here’s how to begin:

1. Join NASTF (it’s free): You’ll get access to scan tool validation, OE service info, and their secure data release model (SDRM).

2. Audit your network: Separate your scan tools, customer Wi-Fi, and office systems. It’s easier than you think.

3. Get your team talking: Whether it’s the shop foreman or the new kid who used to work at Geek Squad—someone on your team can own this.

4. Look at security the way you look at tools: You wouldn’t buy a cheap torque wrench. Don’t trust your business to a $40 router from Walmart.

This is about protecting your business, your customers, and your ability to keep turning wrenches without getting blindsided by a problem you could’ve prevented.

Final Thoughts: This Isn't Optional Anymore

What was once "nice to know" has become "need to know."
Modern diagnostics, key programming, ADAS calibrations—they all depend on digital tools. And the criminals know it.

The good news? You don’t have to figure it out alone.
NASTF is working to support shops like yours with free resources, tools, and training—and they’re not trying to sell you anything. Just trying to keep this industry safe.

So the next time you boot up that scan tool or take in a brand-new Raptor, remember: you’re not just fixing cars anymore. You’re defending your shop.
