The first thing I will say is that
has been deprecated for a long time. It used to be the de-facto tool for viewing and setting the state of networking interfaces.
But it has been superseded by the ip command.
What is the output of the command
Does that show these extra interfaces too?
Can you post the output that you're seeing for these extra interfaces? That might help to yield some clue?
Also I haven't ran Kali in a long time. I used to keep a copy of it on a USB thumbdrive for if I ever needed it.
Is it possible that something you're running in Kali is creating some dummy interfaces or something?
ifconfig and ip don't show any extra interfaces for me in Debian.
If you can post some additional information about these extra interfaces, we might be able to work out what they are.
Your ISP may well be monitoring your online activities - but they wouldn't need to set up an additional networking interface on your machine to do that! The networking interfaces listed by ifconfig will be physical devices connected to your PC, or virtual ones that will be using one of the physical devices. Whatever these extra interfaces are, they are NOT your ISP spying on you!
Typically ifconfig and ip will list the local loopback interface and any wifi, or wired LAN connections. If your PC has bluetooth capabilities - that can also appear as an extra interface in the output too, or if you have a dial-up modem etc.
So these extra network devices are either physical networking devices on your PC, or on other devices connected to your PC - or they are possibly virtual devices that are using one of your physical devices. And again, if it's a virtual one - it's more likely to be created by some program/command you've ran in Kali!
So first, I think we'll need some more detailed information about these additional interfaces you're seeing.
