Step 1
The attacker, using a compromised host, compiles a list of machines that can be compromised. Most of this process is done automatically from the compromised host, because the host stores a mount of information including how to find other hosts to compromise.Step 2
As soon as the list of machines that can be compromised has been compiled, scripts are run to compromise them and convert them into the Trinoo Masters or Daemons. One Master can control multiple Daemons. The Daemons are the compromised hosts that launch the actual UDP floods against the victim machine.Step 3
The DDoS attack is launched when the attacker issues a command on the Master hosts. The Masters instruct every Daemon to start a DoS attack against the IP address specified in the command, many DoSs comprise the DDoS attack.External links
