this is the "you don't have to run faster than the lion, you
just have to run faster than your friend," theory.  as those
who survived to report are a biased sample, it is not well

black hats are opportunistic, but not lazy.  they look for
cracks with mamzing diligence.  e.g the recent brilliant
post on cracking the xbox

when low-hanging fruit is unavailable, or when they see a
really cool way to exploit the higher fruit, it would be
prudent to have done something about it.  who cares about
openly recursive dns servers?  there are easier ways to
crack the host.  oops!

unfortunately, this is not just theory.  few talk about the
serious routing attacks that have been seen.
