这位，显然比俞大猷混的要好，好太多了。不是。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.在20世纪90年代的苏格兰，一群天主教学校的女生有机会去爱丁堡参加合唱团比赛，但她们对喝酒、聚会和勾搭更感兴趣，而不是赢得比赛。Creative modeThe way to arouse curiosity is to directly explain the situation or ask questions to potential buyers at the beginning of the meeting, deliberately say something that can arouse their curiosity, and lead their thoughts to the benefits you may provide them. For example, a salesman handed a note to a customer who refused to see him many times, which said, "Will you please give me ten minutes? I'd like to ask your opinion on a business question. "The note aroused the curiosity of the purchasing manager-what questions did he want to ask me? At the same time, it also satisfied his vanity-he asked me! In this way, the result is obvious, the salesman was invited into the office.
