--An official review of the third chapter follows. My first comment was a little
too generic - "Nice work!"
Upon further review, here are my comments about the third chapter of this book.
Third chapter starts by giving some good overview and details about the main
form of C&C - IRC. The author describes why IRC was originally selected, what
purpose it served and it's pros and cons. The information then moves to the
history of C&C, what the botherders need, what they have available and the
constant "one upmanship" of botherders and bothunters.
As I read this chapter certain thoughts started in the back of my mind. After
the first two sections, I started thinking about why aren't the botherders
using DNS? Well, the next section in this chapter moves directly to that very
topic.
After prepping the reader with this necessary background data, you are then
presented with the meat of the chapter - Alternative Control Channels.
Two different web based C&C servers are discussed and as before, the reader is
given both the pros and cons of each and at times, which bots used which
technology.
Each technology is discussed without getting too detailed and while staying on
the topic - which was very comforting.
Overall, I learned a lot about alternative C&C technology - what's possible and
what we have to look forward to.
Certain web references were used and I found them to provide the detailed
information that I thought was missing from the book. The web references worked
(not outdated dead web links) and were to sites I feel confident with.
I found the entire book worth putting on my shelf. I don't crunch the numbers
to determine if they all add up. I read to add to my knowledge base and this
book fulfilled my need.
