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.

For easier management, We can also create custom chains in a table, Place the rules set for an application in this custom chain, But custom links cannot be used directly, It can only work if it is called as an action by a default chain. We can imagine that, Custom chain is a relatively "short" chain. The rules on this "short" chain are all formulated for an application program. However, this short chain cannot be directly used, but needs to be "welded" on the default definition chain of IPTables before it can be used by IPTables. This is why the default definition "chain" needs to refer to "custom chain" as "action". This is a later remark. We will talk about it later. We can understand it more clearly in actual use.
