Does Shuzku / wireless debugging demand a trusted wifi device? (lemdro.id)

Hey.

I need a wireless connection to use it, right?

And I can't use a selfhosted hotspot, right? It must be a second device, like an external hotspot or a modem.

And I authorize that device to adb level, right?

So if my modem is untrustworthy, it could install malware on my phone?

Thank you for clarification.

Shizuku runs locally on your Android device on which you want to do debugging or perform automated tasks. It's just using the ADB wireless interface to gain access to these functions. I.e. your Android device 'thinks' it's connected via wifi to a remote device which does the debugging.

Fair enough, thanks.

I know it's the app itself that executes adb commands. I just wonder.

https://shizuku.rikka.app/guide/setup/

It says, allow debugging on this network.

So what you're saying is, this is somewhat misleading, for this step doesn't automaticallh grant all devices on the network debug-privileges; and were the modem itself, somehow, applying for them, then it wouldn't have asked for the code as Shizuku is doing, via a notification?

You don't need to be connected to a network to set Shizuku up. Even while you're not connected to an external network (through Wifi or mobile data), your phone has a "loopback" network that allows applications on your phone to talk to other applications as if they were connected through an external network. So if you're scared of giving access to the wrong thing, just turn off wifi & data.
When Android asks you to approve an external debugging connection, it's approved for the specific device that's connecting. Other devices on the network are not allowed to connect. If I use my computer to connect wirelessly to ADB, only my computer can execute commands, not other devices on my network (they'd show another popup).

Hope this helps!

Alright, sweet. Ty both vm.

I'd think I had tried starting Shizuku up without a connection. Just now, I tried to enable wireless debugging without wifi on, and Android said i must turn it on first, but perhaps I can turn it off afterwards, the way you can be on airplane mode then turn wifi on. (This once helped my online radio app cease to leak my system language / location for some reason.)

Will edit this post with further report.
