The sockstreet attack first completes the tcp three-way handshake the tcp connection is established, but in the last ack reply of the three-way handshake, the attacker sets its tcp window to 0 and then makes a data request. When the target discovers that the TCP window size at the receiving end is 0 when transmitting data, it will stop transmitting data and issue a TCP window probe packet to ask the attacker if its TCP window has been updated. Since the attacker does not change the size of the tcp window, the target will always maintain the tcp connection waiting for data to be sent and continuously carry out window update detection. If the attacker uses a large number of controlled hosts to carry out sockstreet attacks, the target will always maintain a large number of tcp connections and carry out a large number of window update detection, and its tcp connection table will gradually run out.
