The real limiting factor for a single attacker who uses spoofing attacks is that if these spoofed packets can be traced back to their real addresses in some way, the attacker will be simply defeated. Although the backtracking process requires some time and cooperation between ISPs, it is not impossible. However, it will be more difficult to prevent distributed SYN flooding attacks launched by attackers using the advantage of the number of hosts in the network. As shown in FIG. 3, these host groups can use direct attacks or further let each host use spoofing attacks.This specification is a PCB design process specification formulated according to the characteristics of our products and the capacity of production equipment.

It also exploits existing code snippets in binary executables for attacks. ROP uses ret instructions to change the control flow of the program, while JOP attacks use indirect jump and indirect call instructions (indirect call instructions) to change the control flow of the program. When a program executes an indirect jump or an indirect call, The program will obtain the destination addresses of its jumps from the specified registers. Because these jump destination addresses are stored in the registers and the attacker can modify the contents of the registers by modifying the contents of the stack, this allows the destination addresses of indirect jumps and indirect calls in the program to be attacked by the attacker.黄胖子一阵苦笑，好，我让你一步，你出便是。爱情大碰撞第一季……
