Facing TCP's three-way handshake protocol, how should attackers launch attacks? The attacker first intentionally initiated a handshake packet. After receiving it, the server puts it into the waiting queue and returns an acknowledgement. Secondly, the attacker will no longer send the third acknowledgement packet, thus the server will make multiple retransmissions (the Linux system configures the number of retransmissions through tcp_synack_retries), consuming a lot of extra overhead, and the waiting queue will be occupied, even the waiting queue will be full, eventually causing the server to be unable to receive the client's request. This is the attack.

The attacker first forged the address to initiate a SYN request to the server (can I establish a connection?) The server will respond with an ACK + SYN (Yes + Please confirm). The real IP will think that I did not send the request and did not respond. The server does not receive a response and will retry 3-5 times and drop the connection after waiting for a SYN Time (typically 30 seconds-2 minutes).
