ABSTRACT
A hacker can easily create, rent, or purchase what is required to launch a bot attack upon multiple machines in order to quickly create a botnet for financial gain. Most botnets range in size from a few hundred to a few thousand infected hosts, with larger and rarer botnets having 50,000-1,000,000 or more bots within the botnet. As stated at the beginning of this book, bots started out as something nonmalicious, but eventually developed into a criminal tool of choice over a ten-year period during the dawn of the World Wide Web.
