Subject: ICMP Covert channels question

"As an attacker, I would not design an exploit that *depended* upon private
addresses being routed external to the victim's router unless I first
verified that they were.

Paul Schmehl (pauls@...allas.edu)"

But Paul, you know that crackers rely on the misconfigured, unpatched masses
to exploit, not the people with properly configured routers and systems.
While you and I will implement ingress and egress anti-spoofing rules, in
the field I see plenty of misconfigured routers that don't.
