不断地给多个 wireguard server 重放这个数据包,wireguard server 会根据 wireguard 协议生成 Handshake Response 或者 Cookie Reply Message 并发送给攻击目标,从而消耗掉攻击目标的网络流量。由于 Cookie Reply Message 数据包比 Handshake Initiation 数据包小很多,从根本上防止了这种攻击方式。

在wireguard 协议中, Handshake Response 包比 Handshake Initiation 数据包小,这意味着攻击者要消耗掉目标 1 G 的流量,必须消耗掉大于 1 G 的流量,这从根本上杜绝了放大攻击。
