What do TCP reset packets do?
Definition. A TCP Reset (RST) packet is used by a TCP sender to indicate that it will neither accept nor receive more data. Out-of-path network management devices may generate and inject TCP Reset packets in order to terminate undesired connections.
What could cause TCP reset?
One reason a device will send a RST is in response to receiving a packet for a closed socket. It’s hard to give a firm but general answer, because every possible perversion has been visited on TCP since its inception, and all sorts of people might be inserting RSTs in an attempt to block traffic.

How is RST flag used in TCP reset attack?
The attacker sends packets with RST Flag ON to both A and B or any one of the host. Since both A and B do not know that an attacker has sent these packets so they treat these packets normally. Since they are reset packets so connection between A and B is terminated.

How Syn Spoofing or TCP Reset Attack Works When a TCP connection is established between two computers, the sending computer sends a TCP RST (Reset) packet to the receiving computer. Before sending the TCP RST (Reset) packet, the sending computer first checks whether the receiving computer is actually listening for the communication or not.
