What, like SS7 phone hijacks and fake base stations tracking, and such, that happen all the time?

1) Who says it doesn't happen?
2) Generally these things aren't on "the internet". They're behind firewalls and on this "other internet" I mentioned between the operators. You can legit buy access to this network for a few thousand dollars, sure. But if you're that serious you're probably not a rando after "rampant vandalism".
