5.4 Pad description:
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.
原本还算有着可爱的脸蛋，可是不知为何总给人一种阴冷诡异不好接近的感觉。这便是刚刚升入高中不久的黑木智子（橘田いずみ 配音），她蓬头垢面，少言寡语，脸上是极度痴迷游戏后留下的黑眼圈。原本以为自己会成为乙女游戏中众星捧月的校花，谁知却注定要成为没有朋友、无人关注的丧女。更无法忍受的，是初中与之同类型的死党成濑优（花澤香菜 配音）都有了翻天覆地的变化。当然，拥有强大内心的智子绝不会因此自甘沉沦，她暗自嘲笑同学的肤浅与轻浮，在妄想世界里体会着前所未有的快乐。只不过依旧耐不住寂寞，这又化作了自卑、嫉妒和各种恶毒的心语。实在逼到极点，便朝向弟弟智贵（中村悠一 配音）。总之，她之所以变成这样，都怪这个世界和周围人而已……

"I remember we had a very clear division of tactics at that time, First, adjust all the automatic rifles in hand to semi-automatic shooting mode, Of the 15 men, apart from the gunners and the bazookas, Most of the others use '81 bars', There are also a small number of 63 types, I'm using the 63, One of the characteristics of this gun and the 81-bar is that the single shot accuracy is especially good, Even better than '56 and a half', Much better than 56 Chong and some Mao Zi guns captured from the Vietnamese, At that time, in order to give full play to this advantage in precision, The company commander ordered us to use this tactic, The concrete implementation is to use heavy machine guns to suppress fire in hidden places, In addition to killing as many enemies as possible, If the enemy takes tactical actions such as lying down to avoid shooting, Then use machine gun fire to limit its movement range, That is to say, they are suppressed in situ, and then rifles are used to give full play to the advantage of high semi-automatic shooting accuracy, giving them "roll call" one shot at a time. This tactic is still very effective in dealing with the first and second large-scale attacks, with extremely high efficiency, and almost all the Vietnamese troops who came up were killed on the way to attack.

The scenarios used in the command mode include: sometimes it is necessary to send a request to some objects, but I don't know who the recipient of the request is or what the operation of the request is. At this time, I hope to design the program code in a loosely coupled way; So that the request sender and the request receiver eliminate the coupling relationship in each other's codes.
Go and see, won't be disappointed!
