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 code:主人公石破天自小没名没姓，和一个他以为是自己母亲的女人，僻居于一座不知名的荒山上。那女人叫他做狗杂种，他便以为这就是他自己的名字。那女人脾气古怪，动辄打骂于他，他也习以为常。他从小学会了砍柴、做饭等种种家务，却大字不识一个，于世事、人心更是一无所知。一天那女人忽然不见了，他自小相伴的那条叫“阿黄”的狗也不见了，便出去到处寻找。结果人和狗都没找着，自己却迷了路。老米的妻子名叫吴琼花，琼花是位典型的中国普通母亲，为家人操碎了心，可这样一个热心肠的琼花，却一直没能当家，原因在于老米的丈母娘佟老太太是个充满生活智慧的老人，佟老太太在世一天，吴琼花就不可能成为一家之主。琼花的妹妹吴金花40岁了还没嫁人，老米和琼花的女儿米青、米蓝都30岁了仍待字闺中，这可愁坏了吴琼花。琼花四处想辄为家中“三朵花”寻求好的归宿。最终三朵花都收获了各自的幸福，琼花也从佟老太太手中接过了当家人的接力棒，全家人幸福地生活在一起。人生这场大戏中，她只是一个按照剧本行事的演员。权贤（申贤俊饰）和弘飚（李秉宪饰）是两个自幼被迫分离的亲兄弟，哥哥权贤被政治世家的权武赫收养，备受宠爱，过着衣食无忧的奢华生活，但他是一个对政治毫无兴趣，又无法适应社会的虚无主义者；弟弟弘飚在...……Deliberately practicing and developing skills are skills that others have come up with how to improve and skills that already have a set of effective training methods.
