No. They just can't see the forest for the trees. In other words, hackers
focus on the hosts not on the network infrastructure. And since they
depend on the network to carry their attacks to their hosts of interest

Hm. What about the "Internet Liberation Front"? They certainly
did attack the infrastructure.

And, then, RTM is their hero. Every weenie out there would love
to say something along the lines "Know that '9x Big Internet Outage?
Like nothing since The Worm? That's me!".
