The attacker first completes the three-way handshake to establish the connection, but in the last ACK reply of the three-way handshake, the TCP window size is set to 0, and then a data request is made. When the attack target sends the request result to the attacker, it stops the data transmission when it finds that the TCP window size is 0, and sends out a TCP window detection packet to ask the attacker if the TCP window has been updated. Since the attacker will not update the window size, the attack target will always maintain the TCP connection and wait for the data to be sent, and continuously carry out TCP window size detection. When the number of controlled hosts in the botnet is large, Target's connection table will gradually be exhausted, resulting in denial of service.
