The first step to prevent DDOS is to have a backup website or at least a temporary home page. In case the production server goes offline, it can immediately switch to the backup website, so there is no way out.
In autumn, they clean up fallen leaves together.
For the convenience of the experiment, we directly use the functions in libc.so.6 as the attack functions to be executed. This is a C program runtime in Linux, which holds a large number of available functions and contains system ("/bin/sh"). Therefore, we can use ROPgadget tool to obtain the code fragments that we can exploit, and use pwntool to exploit the vulnerabilities of vulnerable programs, thus achieving our attack purpose, that is, running system ("/bin/sh"). In order to facilitate the subsequent use of ROPgadget tool to find gadget and attack, it is necessary to copy the libc.so.6 file to the operation directory. First, use the "ldd" command to view the source directory, and then use the "cp" command to copy it to the operation directory.
Reset authentication takes advantage of the reliability of TCP protocol, and DDOS protection system responds to syn first. When the protective device receives syn, it responds to syn_ack and sets the Acknowledge number to a specific value (recorded as a cookie). When the real client receives this message and finds that the acknowledgement number is incorrect, it will send a reset message with a sequence number of cookie + 1. The source of the forgery will not have any response. In this way, we can add the real client IP to the white list. ?

First of all, look at the title carefully. Why not consider intercepting down events but only events after down? Because after intercepting the down event, the event is directly handed over to its own onTouchEvent () for processing, and no longer passes through the sub-View, it becomes the interface of Case 3 (note that this is the interface of Case 3 instead of Case 3, and the internal process is different from Case 3, which will be explained later). After becoming the interface of case 3, the callback to its own onTouchEvent () is divided into non-consumption down and consumption down: non-consumption down is case 1; Consumption down is case 2.
