The Smurf attack is a distributed denial-of-service attack in which large numbers of Internet Control Message Protocol (ICMP) packets with the intended victim’s spoofed source IP are broadcast to a computer network using an IP broadcast address.
trinoo or trin00: set of computer programs to conduct a DDoS 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.
Smurf attack: perpetrators broadcast large numbers of spoofed ICMP packets to a computer network using an IP broadcast address.
Fraggle attack: use spoofed UDP traffic rather than ICMP traffic.
