5 AristotlePagaltzis 3 A distributed denial of service ([DDoS]) attack normally means many clients are sending repeated requests to a machine to saturate its bandwidth and/or processing capacity, preventing legitimate requests from getting through. Nowdays, the clients participating in such an attack are typically so-called "__zombies__", machines infected with a [Virus] or [Worm] containing remote control facilities, typically by joining a secret, password protected channel on some [IRC] server. They can then be instructed to when and where to attack from there. Such a group of zombies is known as a "__bot net__".
