Dan Kaminsky, a frequent speaker at Black Hat, has done some fascinating research into Domain Name Service servers and related security threats potential to them.
Kaminsky started with a very basic premise: Sony has a root kit; all root kits phone home; phoning home requires a DNS query; DNS queries are cached.

He didn't find a few thousand, nor a hundred thousand. Kaminsky found roughly 568,200 DNS servers that have signatures of the Sony root kit calling home.
