From the excellent Book "Cisco Router Firewall Security":
Smurf is a DoS attack that uses ICMP echos. The name Smurf is used because
this was what the original hacker application was called. A hacker using
Smurf uses two things that can create a massive DoS attack against your
resources.
Fraggle is very similar to Smurf, but it uses UDP echos instead of ICMP
echosbasically, someone recoded Smurf to work with UDP.
