DoS: An exploit whose purpose is to deny somebody the use of the service: namely to crash or hang a program or the entire system. Examples of DoS attacks include flooding the victim with more traffic than can be handled; flooding a service (like IRC) with more events than it can handle bomb; crashing a TCP/IP stack by sending corrupt packets; crashing a service by interacting with it in an unexpected way; or hanging a system by causing it to go into an infinite loop. For example, the Ping of Death exploit crashed machines by sending illegally fragmented packets at a victim. A common word for DoS is ""nuke"", which was first popularized by the WinNuke program.

Flooder: A program that overloads a connection by any mechanism, such as fast pinging, causing a DoS attack.

Spoofer: To spoof is to forge your identity. Attackers use spoofers to forge their IP address (IP spoofing). The most common use of spoofing today is smurf and fraggle attacks. These attacks use spoofed packets against amplifiers in order to overload the victim's connection. This is done by sending a single packet to a broadcast address with the victim as the source address. All the machines within the broadcast domain then respond back to the victim, overloading the victim's Internet connection. Since smurfing accounts for more than half the traffic on some backbones, ISPs are starting to take spoofing seriously and have started implementing measures within their routers that verify valid source addresses before passing the packets.
