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.

Now, let's imagine why these "checkpoints" are called "chains" in iptables. As we know, The purpose of a firewall is to match "rules" for passing messages, Then execute the corresponding Action, So, when the message passes through these checkpoints, You must match the rules on this level, However, there may be more than one rule on this level, But there are many rules, When we put these rules in a chain, A "chain" has been formed. Therefore, we imagine each "checkpoint" as shown in the following figure. In this way, it is more appropriate to call them "chain". Each message passing through this "checkpoint" must match all the rules on this "chain". If there are qualified rules, the corresponding actions of the rules will be executed.
