Subject: DNS poisoning

Since Bind is open source, one needs a good knowledge of c/c++ and some
time. 

create a few "legitim-looking" security pages, spread among clueless
sysadmins as a "security upgrade" (is binddns.org taken?) and let them
do the work for you. 

As I recall there's a rogue azureus doing something like that, spreding
spywares and trojans.
