M1 MacBook Air high network activity while sleeping.

I've observed that, after leaving my M1 MacBook Air all night sleeping, plugged to the power supply, after waking it up, it has been doing a lot of things "network-wise", I mean, look at the data indicator:

That screenshot is just after waking it up, the flat lines of the right are from the few seconds awake.
I've unticked the option of "keep network activity while sleeping", just to see if next time it will have this behaviour or not.

What do you guys think about this? Could an app be spying me sending data while the computer is sleeping?
Thank you.
