Fraggle Attack-

A perpetrator sends a large amount of UDP echo packets at IP broadcast

addresses, all of it having a spoofed source address of a victim.

IP Spoofing is a method of masking the identity of an intrusion by making it appeared

that the traffic came from a different computer. This is used by intruders to keep their anonymity
and can be used in a Denial of Service attack.
