Can my phone compromise my other (vpn) devices?

VPN

Can someone please clear something up for me:

Suppose I use a vpn client on my computer and my phone is connected to the same network (via wifi).

Is my phone “compromising” my connection to a vpn server or is it unrelated and cannot be traced to my computers traffic.

All the traffic from your PC will be encrypted and safe. All the traffic from your phone will not be encrypted.

So no, it does not compromise the PC’s connection

if your phone compromised something, it would most likely spread over your wifi and not through your vpn tunnel/account. Or bluetooth if ur computer or something else besides the phone has bluetooth too. It would be less likely to have to do with the vpn. It’s not impossible though, perhaps the vpn you use has an option to connect your devices to each other through the vpn, in which case it’s possible. Or if the vpn service is insecure, fired up Angry IP scanner once on a, well not a major VPN but not unheard of either, and was able to see other clients on the vpn server’s local tunnel network. The software only required 1 iptables rule to prevent it too.

Also sometimes vpns even the big ones end up accidently bypassing the firewall on the client’s own local windows machine.

Attacks over local networks are much easier than trying to hack a major vpn server though. This is why in the case of assuming your phone were already compromised, it may enable the wifi antenna and start scanning/attacking wifi instead. Bluetooth is more vulnerable than modern wifi protocols as well.

In theory, maybe

Non-encrypted traffic from your phone could be tied to your router IP

It’s still possible to figure out what sites are being visited by the machine using the VPN

If you are accessing highly questionable/ illegal content on the PC, there are techniques that could tie it to you IRL, or at least your router

A VPN circuit running on the router with kill switch would be far better

Thank you for your answer.

I’m just considering the case where I wouldn’t run it.

Or some other device (maybe some IoT, smart home thing) is not using the vpn.

Thanks, a vpn router seems like a good idea.

Unfortunately couldnt get anyone that would work with my setup for now.

Well yeah if you’re logged into your VPN and your Google account on the same device, Google will know that you use a VPN. And probably which one.

Logging into your Google account on a device with or without a VPN has the same effect. Google will know who you are, does not really matter where else you are logged in or not.

If google is your concern, a VPN is not the solution
