In addition to solving the port problem of A, the serial number problem also needs to be paid attention to. The serial number corresponds to the sliding window. The fake TCP packet needs to be filled with the serial number. If the value of the serial number is not in the sliding window of B when it is sent to B before A, B will actively discard it. So we need to find the serial number that can fall into the sliding window between AB at that time. This can be solved violently, because the length of a sequence is 32 bits, and the value range is 0-4294967296. If the window size is like 65535 under Windows I caught in the above figure, I only need to divide, and I know that at most I only need to send 65537 (4294967296/65535=65537) packets to have a sequence number fall into the sliding window. The desired value can be calculated quickly by exhaustion on multiple control hosts.
Although the propaganda posters of the Second World War once said the truth that "more words must be lost", "knowledge is power" is also an indisputable motto, especially in the protection of modern business technology systems.

Facing the security threat, what everyone needs is smooth information, new attack data and the development trend of defense system, all of which need a good communication environment.

However, when the wisdom of the 18 players is integrated, any problem can be solved. Unity and mutual assistance, difficult challenges, this is the main theme of this activity.
