In the past, Osaka Weaving House hardly seriously considered member marketing. This is because there are too many zombie fans in the member system and the unit price of customers is low. No matter WeChat or SMS, they are no different from harassment in communication scenes and have little effect.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.就在“上海五万人”举办前夜，多年来努力的目标眼看就要实现，ROCKY却收到了MAY的消息！ ROCKY不顾团队所有人的反对，一意奔回家乡见MAY一面……他相信他绝对可以及时返回，顺利创造奇迹……在这部全新单口喜剧特辑中，坦诚而内省的喜剧演员西蒙·阿姆斯特尔敞开心扉，谈论了自己的神经质、向父亲出柜的经历以及情感关系等话题。First of all, in the idea of plane-oriented programming, the functions are divided into core business functions and peripheral functions.岂止百分之九十的游戏是垃圾，应该是百分之九十九都是垃圾。However, whether this is a war remains to be discussed.
