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.
