Why use tor when you can ride the carriers wave?


This report is an example:
https://github.com/0verdu/Stepped-On_Silicon/blob/main/infrastructure/tmobile_usa.md

Tor isn’t even in the picture. The setup bypasses the MVNO layer entirely and hits the MNO core to tunnel into private 
AWS space (172.31.35.241).

When the C2 is integrated into the IMS core and uses a system-level NEVPN, it’s invisible to the user.

The most detailed analysis I have seen makes no mention of C2s comms via
TOR.  If you have a reference that it does, can you share?
