Dave Bittner asked how seriously critical infrastructure should take the wave of attacks on refrigeration controllers. Grove was describing a small store owner running a few freezers who likely doesn't know the devices are vulnerable. It frames the mismatch between who owns these systems and who is attacking them.
…hitting like the defrost mode and going up to as high as like 175 degrees on something that's supposed to be a freezer. And that's the impact. And how it happened, they don't always know. They just know these are some of the ways that it could have happened. And these are happening a lot lately.
In terms of protecting critical infrastructure, to what degree do we take this seriously? How much is this a cautionary tale for other verticals?
…the day that those things will matter. So it's a challenge for a lot of them. And if I, again, back to my example, if I'm running a few stores and I have these freezers in there, there's a very good chance I don't even know that these are vulnerable. I don't know what to do if they were. And I don't know even maybe where the network connection is. It's probably not something that I'm focused on. I'm focused on restocking the shelves, hiring employees and selling lottery tickets. And asking them to defend against a potential nation-state adversary is a huge ask. It's like asking your neighborhood police force to defend against an army from another country.
So how do you suppose the industry is going to respond to this? You know, both the cyber industry and the folks responsible for the refrigeration units themselves.
Yeah. So the industry that creates the refrigeration controllers and freezers and such have been already responding, but they've end of life to these things like a decade ago. So they are trying to notify the customers they know that I have these to get these off the internet. They're not…
That's Chris Grove from Nozomi Networks. When you run security for a company that's scaling fast, the stakes just keep climbing. More compliance frameworks, more vendors, more risk, and a board that wants to see it all in one place. And all the information you need, it's scattered everywhere.…
