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.影片围绕孙老大神秘的创造奇迹的锅底秘方展开，在重庆某条美食街上，孙老大（罗家英饰）的火锅店因其锅底味道奇佳而闻名遐迩，引来众多竞争对手觊觎他的锅底秘方。马大狗（姜超饰）、马二狗（庞勃饰）两兄弟为了自家的火锅店能在美食街站稳地盘，千方百计找到了对美女花言巧语、对合伙人油嘴滑舌、开溜第一、阅历赛过任何一个混混的唐少爷（袁成杰饰），并成功抓住唐少爷的把柄，威逼他帮忙偷秘方，并由此做出了一系列爆笑行为，令众人大笑同时，又感甚囧、甚雷。影片由此引发了一系列国产“计中计”、“谍中谍”的爆笑偷盗事件，却又在最后发现了一个被隐藏了多年的大秘密……TCP (Transmission Control Protocol) is a connection-oriented, reliable, byte-stream-based transport layer communication protocol defined by IETF's RFC 793.
