PPC Hijacking

First let me preface this topic with the fact that I am not an expert in DNS but am learning something new every day in regards to DNS. Some of what I'm going to say may not jive and I would like for those who know for sure that what I'm saying is wrong, to step up to the plate and tell me that I'm wrong, please!

Okay, so what led me to this topic?

In that last topic on DNS Cache Poisoning, I referenced a document from the LURHQ Security Systems site titled PPC Hijacking. It can be found here...

The above document is dated 2005-04-01, just over a year ago. If you've been following the above topics at WebmasterWorld on DNS Recursion and DNS Cache Poisoning, you'll see that the warnings have been around for years.

Much of the above document may be totally incomprehensible to some. It was a bit overwhelming for me until I printed it and then carefully studied each and every step they took to perform their tests. WOW! It was an eye opener. As I am somewhat familiar with server header status codes and such, it was pretty amazing to see everything that was taking place in this particular instance of PPC Hijacking.
