The attack got its name from the Zeichentric kfilm of the 1
Smurf attacks were extremely easy to implement before the late 1990s, as most networks were poorly configured and could not resist abuse in this way. Since then, hosts and routers have routinely been configured to not respond to ICMP requests addressed at the IP broadcast level or forward requests that they receive.
