Security Issue?

[ElGreco]

Looking at my Google Wifi application(via Home app) it show that an OOMA device was previously connected to my network.

I don't use OOMA. I checked the MAC address and it matches the range of OOMA devices. I can't figure this out at all. I use a very strong password, still after discovering this I turned on WPA3 on my Google Wifi(original not the NEST).

The app shows lots of previous unnamed devices connected which I believe is because of MAC Address Randomization being the default on my Pixel Phones.

The Ooma device though is what I am concerned about.

I am at a loss here any ideas? Any help would be appreciated. Thanks

Could be the MAC randomization all modern OS-es are doing by default these days? Windows, iOS, Android, all do it.

[ElGreco]

Thanks for the reply. I understand about MAC randomization. I posted that in my original post. The question was/is about an Ooma device that is showing as being connected previously. I do not have an Ooma device. The MAC address matches the Ooma range of devices as well.  So that was my question. Not about MAC randomization. Thank you

[olavrb]

Ah, sorry, missed that.

But if you randomize a MAC address, chances are you can get one that matches a given hw manufacturer, right?

[ElGreco]

I don't think that's very likely.

Hey, ElGreco.

It's been a little while since you and olavrb were working on this. I wanted to check in to see if you were still seeing this issue or to see if you were able to get it sorted out. I would be happy to jump in and start helping. Let me know if there's anything I can do here.

Thanks.

Well I did a factory reset and password change on the router and verified all the devices on it. The OOMA device that showed up was troubling. Obviously it didn't have the signature of MAC Randomization(2nd digit a,e, 2, or 6). The Gold Product Expert did not take that into account when he told me it was due to MAC randomization. Maybe other people can learn from this.

[olavrb]

I admit that I learned something new about spotting a randomized MAC address.

I just found it very unlikely that you had a device connected to your network that you don't know of/ can't find, that's why I chased that idea.

Good that a factory reset and different Wi-Fi password made it not reapoear. Would be interesting to know what it was though.

[ElGreco]

It is unlikely!  I used a very strong password. I have no idea what happened.  I decided to do a factory reset and change the password. I feel like I might want a router with a little more control. I hope Google decides to get into Wi-Fi 6 because this thing is getting old and falling behind. 

[olavrb]

I agree about Wi-Fi 6. More control, then maybe a pfSense box with UniFi or similar access points? I like simplicity though, as in set and forget. I work with IT and don't want to work at home too. And haven't experienced what you did here during the 3-4 years I've had Google Wifi, then Nest Wifi. Even with a relatively simple Wi-Fi password. 🙂

[ElGreco]

Yes, I appreciate the simplicity of the Google mesh system. I use Pixel phones as well and  the new Pixel 6 is Wifi 6E  capable( only device that is 6e so really don't need a 6e router). So I have no idea what happened with the OOMA device. I am cautious though so I thought I better reset. 

Still something likely simple instead of some kind of weird intrusion.

Hey, everyone.

Activity trailed off a bit here so I wanted to check in and see if you were able to get this sorted out, ElGreco, or if it remains an ongoing issue. If you're still looking into this, just let me know.

Thanks.

[ElGreco]

Factory reset router and reset password. No issues since

[Jeff]

Perfect, ElGreco. I'm happy to hear you've not had any troubles. Is there anything else I might be able to help on before we mark this as resolved?

[Jeff]

Hi, all.
As we got our resolution here, I'm going to mark this one as resolved. Thanks to all who helped and contributed. If anyone has any other needs, please feel free to open up a new thread.
Thanks!
