Smurf攻击通过使用将回复地址设置成受害网络的广播地址的ICMP应答请求(ping)数据包，来淹没受害主机，最终导致该网络的所有主机都对此ICMP应答请求做出答复，导致网络阻塞。更加复杂的Smurf将源地址改为第三方的受害者，最终导致第三方崩溃。(Smurf attacks use the ICMP reply request (Ping) packet to set the reply address to the broadcast address of the victim network to drown the injured host, resulting in all the hosts of the network respond to the ICMP reply request, resulting in network blocking. The more complex Smurf changed the source address to the victim of the third party, which eventually led to the collapse of the third party.)
