The goal of this network attack is to create a crushing amount of traffic. This attack strategy came about as a function of ICMP (Internet Control Message Protocol) and the network broadcast address.

If an attacker has a large network segment that he is aware of, he can send a ping or an ICMP Echo Request to that broadcast address. Each host on that network should take that because the broadcast address was used, though the Echo Request is actually destined for itself.

An Internet Control Message Protocol (ICMP) Smurf attack is a brute-force attack on the direct broadcast feature that is built in to the IP protocol.
