What is a DDOS Attack?
One DDoSer can do a lot of damage. These denial of service attacks are called distributed because they come from many computers at once. A DDoSer controls a large number of computers that have been infected by a Trojan virus. The virus is a small application that allows remote command-and-control capabilities of the computer without the user’s knowledge.

What is a zombie and a botnet?
The virus-infected computers are called zombies – because they do whatever the DDoSer commands them to do. A large group of zombie computers is called a robot network, or botnet.

What is a DDOS Attack command-and-control server?
Zombie computers in a botnet receive instructions from a command and control server, which is an infected web server. DDoSers who have access to a command and control (C&C or CC) server can recruit the botnet to launch DDoS attack. Prolexic has identified more than 4,000 command-and-control servers and more than 10 million zombies worldwide. We track them and notify law enforcement to disable them when possible.
