Actual Behavior

[mailinglists35]

the type of tab seem to not have any significance. it behaves the same if the default session is cmd.exe as well.

We don't have any code that passively attempts to establish a connection anywhere.

If your firewall application blocks further execution of the calling application, this could be a good way for us to find out what it's doing. If that's the case, can you use Task Manager and collect a dump file from WindowsTerminal.exe?

Thanks!

185.125.190.29 belongs to Canonical and is pointed to by ubuntu.com. I believe the online connection is mis-attributed to us and is actually caused by your WSL setup. This wouldn't be surprising for me as Ubuntu's MOTD contains advertisements for its products. You could try running sudo run-parts /etc/update-motd.d/ to test this.

at first I was inclined to dismiss this with suspecting canonical, but I am intrigued by the fact that the firewall triggers even if all wsl sessions stopped and changing default tab to cmd.exe.

sudo run-parts /etc/update-motd.d/ does not seem to trigger the firewall prompt.

[mailinglists35]

also, if wsl does establish the connection itself, how can it technically get in the windowsterminal.exe process network space?

I've had previous firewall prompts for example when doing apt updates for the first time, which did show up in firewall as their own .exe processes, not as windowsterminal.exe
