Figure 1 is an example of a JOP attack. In this example, the attacker's aim is to execute a system call "int 0x80" to open a new command line window. To do this, an attacker needs to modify the contents of the eax register to "0x0000000b" and the ebx register to the string "/bin/sh" before "int 0x80" is called, and the ecx and edx registers must point to the value "0x00000000". Suppose the value "0x0000000" and the string "/bin/sh" can be found in memory when the program is running. An attacker needs to construct the value "0x0000000b" himself. However, for the value "0x0000000b", when an attacker saves data to the stack through a buffer overflow, the "0x00" byte will trigger the system to terminate the read operation. This example specifically describes how the attacker uses the existing code snippet in the program to modify the value of val pushed into the stack by the attacker step by step from "0xffffff0b" to the value required by the system call "0x0000000b", thus implementing JOP attack. The following are the detailed steps of the process.

PS: There are many other boxing methods. Generally, the damage energy ratio is about 50, with different buff. It is not bad either. It is just not within our consideration, but you are also welcome to add.
In fact, there is another way to implement the state machine. The core of this method is table-driven. It can be clearly seen in the table that the next state is determined by the current state and behavior. This allows you to look for states in the table without having to define many conditional branches

The premise of HTTP interception in the previous section is that the request must have characteristics. However, a real DDOS attack has no characteristics. Its request looks the same as a normal request and comes from different IP addresses, so it cannot be intercepted. This is why DDOS is especially difficult to prevent.
