Comparing DoS Attacks with DDoS Attacks抢书生风铃的那位瞪着眼上前，摸出了四贯整串的铜钱，往车上就是一拍。Episode 29Figure 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.故事讲述的是朋友赫迪（瓦莱丽·斯托尔）、弗里茨（莉亚·冯·布雷尔）、哈利（乔尔·巴斯曼）和乔治（达米安·蒂恩）。赫迪是弗里茨父亲拥有的仓库的销售助理。在卡德威的一次抢劫中，两人相遇并坠入爱河。尽管有相当大的社会阻力，以及家人的反对，这两个截然不同的年轻女性开始了一段关系。另一个不寻常的联盟是，弗里茨的哥哥哈里（乔尔·巴斯曼饰），他是一名退伍军人，回来接管仓库，不得不与年轻的职员乔治（达米安·蒂恩饰）对质，哈利严厉的父亲信任他。这次007对手是臭名昭著的国际恐怖分子雷纳德。为了垄断石油供给权，雷纳德杀害了石油大亨罗伯爵士，当然他也不会放过罗伯爵士的继承人——美丽的依蕾克屈，这个狂人甚至威胁说要在土耳其巨大的输油管道里引发核爆炸。于是007必须驾着高速快艇从西班牙比尔堡的奈维河岸到伦敦的泰晤士河边，再穿越苏格兰的高地，冒着几乎不可能生还的危险去保护罗伯爵士队唯一继承人、粉碎雷纳德的阴谋。连场大战一触即发！
