Infected computers are called bots or zombies. When this happens, bots become slave for the instructor or creator of Bot Net. Bot Nets are programmed in such a way that they are difficult to find and analyze. Normally they receive instructions from their creators through Internet Relay Channels. Zombie computers can also be used for denial of service attacks in which many bots simultaneously log onto a particular server, thus exceeding the server’s bandwidth and crashing it. This technique is particularly effective when the Botnet is large and contains thousands of computers.
