Why doesn’t the wrench then only have the ability to talk to a local server and that server have internet then? If that were the case the wrench would have no reason to download anything from the Internet, just speak to the local server. Probably wont fix every vulnerability but it can’t be more vulnerable.
The wrench has a web UI to program it or monitor it. It also talks a few “standardised” car-manufacturer protocols for recieving and sending instructions/measurements/certifications. And it can send also send stuff to a local history server.
The majority of the CVEs seem to exist in its onboard webUI system, with a few in the manufacturing protocols.
But yes, IoT devices should be on an isolated vlan or on pvlans. That should be standard practice.
Access from wrench->server should be via a firewall that logs connections. And access from management->wrench should be via firewall with logging.
There is no reason for unauthorized people to have access to the wrenches network, and there is no need for the wrench to communicate with anything other than the local history server.
This feels like one of those things that’ll go exactly opposite of what I expect. Ten years from now I’m be explaining to my grandkids how much harder live was before wrenches were Internet connected.
I can’t imagine a single valid reason to have an Internet connected wrench. But life is weird, so I’m guessing I’ll keep one synced to my fax machine someday.
I think I am less concerned about the ransomware and more confused as to why there is a wrench that can connect to the internet. What use would that provide to the user that would improve it?
Eeehhh I prefer the OG style of torque wrenches myself, I don’t even like the digital ones. They all eventually die but the digital ones seem to die quicker. It ain’t efficient if it’s broken. And to that effect, if it ain’t broke, don’t fix it, the clicky ones work fine. Bonus: they go clicky clicky.
I mean, for an automated assembly line sort of deal with not me involved? Hell yeah whatever, robots and shit. If I’m wrenching? Clicky clicky.
OH and yeah, clicky has no wifi, thus to ransom it you need to physically steal it and send me a letter with letters snipped from a magazine and tell me where the hollow tree in the park is to do the drop, whole different animal.
That’s the neat part, there isn’t. There is, however, significant incentive to the tool’s manufacturer. Who can, I’m sure, not only demand a subscription for continued use of the tools but also employ lucrative maintenance contracts and other sundry corporate nonsense. I can tell you from a brief stint in the industrial automation industry that the sale of the equipment is not the money maker; it’s the ongoing service contract on it.
If these are meant to be used by hand I see no reason they can’t just be configured on the tool itself and not need an internet connection. And if the point is plantwide automation, these sit directly in the bottom of the ugly trench between tasks that must be done by a human for whatever reason on one side, and just being done by a damn robot to begin with on the other.
And a further clarification: Even if there is a use case for a hand tool being networked, having it connected to the outside internet is just bonkers.
I see no reason they can’t just be configured on the tool itself and not need a network connection.
Say you've got a couple dozen of these wrenches and during retooling new specs come out. You can either pay a group of people to go around and upload all the new specs to the tool or push it from a central server to all the tools.
So, like, the guys who are holding the wrenches all day to begin with?
Even so, none of the examples anyone has come up with in this thread have required having the friggin’ things connected to the internet. That’s our beef here. Not necessarily networking capability.
In fact, back when I was in automation (in the dark ages of ~2008) it was already considered unthinkable not to air-gap all of your mission critical production equipment. A ton of that stuff was networked, sure (and you’d shit a brick if you saw how much of it is still interconnected with RS-485 serial…) but not exposed to the outside world in any capacity. Nor would anyone want it to be, for obvious not-getting-pwned reasons.
I’m not saying all of these are good ideas, or that they couldn’t just have a centralized hub that just pushes and pulls this information. That said, the website for them does list that they also have a camera for scanning barcodes. I could see having barcodes linked with a certain torque spec and that requiring a network connection if the information wasn’t hard coded. website
