    In the Smurf Attack the ,attacker send ICMP packets to the target of the attack. And after this attacker try to send these datagrams of ICMP to LANs broadcast addresses by using the directed broadcast addresses. All the alive hosts try to pick up this ICMP datagram . Than try to send reply to each of this datagram request. This type of attack can affect more than 100 hosts at single time. In this attack the attacker may use large sized packects for to increase the attack effectiveness.

    Hi,

    The Smurf Attack is basically the sub-type of Denial Of Service Attacks(DOS Attacks). The Smurf Attack causes the degradation in the victim's performance. It also responsible to slow down the intermediary networks, network congestion. This attack doesn't allow the authorized user to to get the services of network. In this type of attack every host replies result into the flooding and congestion of the network.
