This is usually achieved by spoofing the source IP address to be that of the target. When the intermediate system receives the packet, it looks to all intents and purposes as if it was a legitimate request from the target. Reflection attacks were of technical interest but become particularly significant when combined with amplification. This enables an adversary to leverage infrastructures already deployed on the internet, to deliver a crippling flood of data onto the target without crippling his or her own network.
