	Preventing Smurf Attacks
		SMURF and similar Denial-of-service (DoS) attacks can do serious damage to your network services, be it either as an individual end-user or as an entire institution in that your network or host can be inundated with unwanted and maliciously sent traffic.
		A SMURF attack (named after the program used to perform the attack) is a method by which an attacker can send a moderate amount of traffic and cause a virtual explosion of traffic at the intended target.
		There is also an informal SMURF Amplifier Registry housed by the norwegian ISP PowerTech, which in the form of a «hall of shame» lists active amplifier networks.

		Folks, it would seem that there's ample work left to inform your customers that they should take the necessary precautions to prevent their networks from being inundated with traffic by being exploited as an amplifier in a "Smurf" denial-of-service attack.
		It might be a good idea to point out that doing the work to prevent this from happening is also in their own best self-interest.

		It relies on mis-configured network devices that allow packets to be sent to all computer hosts on a particular network via the broadcast address of the network, rather than a specific machine.

		This involves first identifying potential targets by looking for critical hosts using DNS, MX records, etc. Once the targets have been discovered, the next step is to identify the types of attacks that can be executed by scanning the system with host scanner such as nmap or netdiag.
		A smurf attack involves three elements: the attacker, the amplifier networks, and the primary target.
		While not as lethal as smurf, there is the added potential for the attacker to implement a ping-pong attack.

		The amount of traffic sent by the attacker is multiplied by a factor equal to the number of hosts behind the router that reply to the ICMP echo packets.
