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.

For spoofing attacks, the first thing to consider is to choose the address. For the attack to succeed, the host on the spoofed IP address must not respond to any SYN-ACK packets sent to them. A very simple method that an attacker can use is to disguise only one source IP address, and this IP address will not respond to SYN-ACK packets, perhaps because there is no host on this IP address at all, or because some configuration has been made to the address or network properties of the host. Another option is to disguise many source addresses, and attackers will assume that hosts on some of these disguised addresses will not respond to SYN-ACK packets. To implement this method, you need to recycle the addresses on the list of source IP addresses that the server wants to connect to, or make the same modifications to hosts in a subnet.
