NOTES:

It accepts the following parameters:

• {IP address} {hosts} {number}
• IP address = IP address of target victim
• hosts = a file containing list of reflector servers
• number = number of loops

This Trojan is used to perform Reflective DDOS (Distributed Denial Of Service) to a target IP.

It sends SYN packets with a spoofed source IP (target victim's IP) to the reflector servers.

All of the reflector servers will reply with SYN/ACK packets to the target victim.

Due to large number of replies, the target victim's bandwidth gets flooded (TCP SYN Flooding).

It does not have rootkit capabilities.

It does not exploit any vulnerability.
