ABSTRACT
Do you really know what your computer is doing? Maybe you don't - your
computer could be a "zombie" thanks to malicious software. "Bad guys" amass
huge networks of zombie computers, ready to do the bad guys' bidding
unbeknownst to the computers' real owners. I'll explain how this all works,
and describe some typical applications of zombie networks: sending spam and
launching distributed denial-of-service attacks.
In an effort to stay a step ahead of the bad guys, we've been looking at new
threats from zombie networks which have not yet been seen in the wild. I'll
present two of these: preventing analysis of malicious software, and sending
spam that is much more deceptive. Find out what defensive measures can be taken
now against these threats.
