At the risk of being called a neckbeard:
In other words, they were hyping up capabilities they don't have.
Are you familiar with Wireshark and network sniffing? Instead of just wondering, why not look for yourself what these devices are sending out? It's not hard, and it's not a secret.
I'm not scared of them, because I know exactly how they work and exactly what's going across my network at all times.
Are you able to dissect the packet contents tho? I can see the raw hex payloads of any packets on my network but that doesn't really tell me much about the data actually in them
You can at the very least tell when it is and is not transmitting data when you talk around it. You can set up experiments, like having a casual conversation with and without the "wake word" and compare packets. If it starts spewing data every time you talk, or if it remains mostly idle with just occasional DNS lookups or NTP updates and such, you'll know.
Is there a way to route traffic from the router to Wireshark? Or would this require a router capable of like OpenWRT?
I have a stupid linksys that has awesome wifi power, but I can't seem to get custom firmware on it. I might be able to configure it as an access point.
My router is a full on Linux server PC in a rack, so in my case I can just monitor all its interfaces directly on the box. I've got an entirely seperate VLAN for my IoT stuff (because a LOT of them are still very unsecure and I'm more scared of my network being compromised that way, by them just getting straight up hacked).
An easy way to do it in your case if you have a gimped ISP-provided router is to find an old hub (not a switch), plug a wireless access point into that, and have the device connect only to that access point. Then plug your laptop or computer into one of the other hub ports and you should be able to listen in on everything being sent across that hub.
More advanced switches might be able to do port-mirroring, which accomplishes the same thing.
Haha I have of those thanks.
