attack. It is believed that trinoo networks have been set up on thousands of systems on the Internet that have been compromised by remote buffer overrun exploits.
The first suspected trinoo attacks are described in

Trinoo is famous for allowing attackers to leave a message in a folder called cry_baby. The file is self replicating and is modified on a regular basis as long as port 80 is active.
Trinoo was authored by a teenager from New Orleans who went by the alias phifli.
Using Trinoo
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.
