Reflective DDoS attack

A twist on type of distributed denial of service attacks in which a SYN flood is sent to a large Web site, but the packets have a spoofed source IP of the real attack target.

The Web site replies to this large number of SYN requests by sending its responses to the spoofed target IP address. To the target, it looks like the large Web site is launching a DDoS attack against it.

From Denial of service: Fighting back, Network World, 09/02/02.
