These attack tools changes the characteristics of packets in the packet stream such as the '''Source IP Address''' to hide the real source of the packet stream. The method of sending packet streams to one or more intermediate sites to create responses that will be sent to a victim is called '''IP Spoofing.'''<ref>[http://www.iss.net/security_center/advice/Underground/Hacking/Methods/Technical/Spoofing/default.htm Spoofing]</ref> Other packet stream attribute being altered by intruders are the '''Source/Destination Ports''' and '''Other IP Header Values'''.
