Smurf Attack<p>A Smurf Attack is a distributed denial-of-service attack in which large numbers of Internet Control Message Protocol (ICMP) packets with the intended victim’s spoofed source IP are broadcast to a computer network using an IP broadcast address. Most devices on a network respond to this by sending a reply to the source IP address. This can slow down the victim’s computer to the point where it becomes impossible to work on.</p> <p>See also: Smurf Attack</p>
