古代希腊的青年季米特里奥斯，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.后续的影响远远不止如此，当日项羽便派了龙且和虞子期赶往无延，追杀宋义之子宋襄。A staff member of a communication base station supporting construction enterprise told CCTV financial reporters that in the past few years since joining the company, he has received the most tasks this year.Ni Ping Spokesman: 1.5 million RMB per year Li Jiaxin Spokesman: 2.2 million Hong Kong dollars every 2 years一老一小静静对视着，传达不可言喻的沙场壮志。In addition, the structure of the mind map is divergent, which is very beneficial to the divergent thinking and creative thinking of the brain, and it is also easy to add new content. However, if new content is added in the middle of the two lines of text notes, the traditional linear notes will become dense, and even the lines will be introduced everywhere, which is neither good-looking nor conducive to summary.
