If an attacker sends SYN packets quickly with their own undisguised IP address, this is a so-called direct attack. This attack is very easy to implement because it does not involve spoofing or modifying packets below the user layer of the attacker's operating system. For example, he can simply send many TCP connection requests to implement this attack. However, for this attack to work, the attacker must also prevent his system from responding to SYN-ACK packets because of any ACK, RST, or ICMP (Internet? Control? Message? Protocol) will cause the server to skip the SYN-RECEIVED state (go to the next state) and remove the TCB (because the connection has been successfully established or recycled). Attackers can do this by setting firewall rules, causing the firewall to block all packets (except SYN) to reach the server, or causing the firewall to block all incoming packets so that SYN-ACK packets are discarded before reaching the local TCP handler.

You can see the difference between the modified and the pre-modified, As shown in the following figure: Three, the problem in the experiment Question 1: At first, when I chose the experimental website, I chose the rebate website. It is also a website that does not need to enter a verification code to log in: but when I intercepted the page login information, I found that the website did not respond to the login key I pressed and did not make any jump, so I did not intercept any login information. Is this the defensive measure taken by the website to prevent replay attacks? What is the principle? Question 2: I don't think the interception and use of BurpSuite software is very successful. If it is really used as an attack method, I think it is too easy to be discovered by the attacker, or what is wrong with my use?
