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.漂洋过海的移民，也许充满了太多的不测与困难。The strategic perspective of the financial industry can and should be widely extended to all walks of life.回头折腾病了，反让玉米过意不去。我们分析，十有**是玉米要走，被小苞谷发现了机关，便跟了去。章家的三朵花，一朵清香雅丽，一朵红艳脱俗，一朵最美最甜却最多刺，因上一代的恩怨，造成下一代的牵连纠结，最终酿成无法挽回的遗憾。灵界之初，阴阳未分，瞑涬鸿蒙，后大道萌芽，灵神生其中，灵神创灵界万物，并于源神谷将自身力量化作【九件圣天灵器】，维持灵界稳定，生生不息。 灵界人族——炬皇，懵然中发现修炼大道碎片【灵气】的方法，以此成为第一代统治人族的王者，他发现了源神谷的强大力量，于是深入源神谷，妄图以凡人之躯掌握神之伟力，然圣天灵器异常强大非凡人所能染指，炬皇最终被强大的灵力吞噬，炬皇临终前有言：继承九件圣天灵器者，获永生，与天地齐寿。 现如今，普通人只能生活在圣天灵器护佑的城市之中，灵界被玄阳，月族和山海联盟分割，三足鼎立，勉强维持着表面的和平… 影月族族长之女影月琉璃作为影月族的继承人，天赋异禀，族人都希望她可以带着影月族重新崛起。但是琉璃却只想过简单轻松的生活，当一条咸鱼。
