[0097] Based on a three-level hooking communication design method, the system adopts a hierarchical hooking structure. The communication port structure contains three hooking modules, such as... Figure 2 As shown:

[0098] The adoption of a three-tiered hook system is determined by actual needs, such as... Figure 2 The analysis proceeds from top to bottom. For the payload to be triggered and executed, the communication interface needs to hook into the operating system kernel. The system chooses the system call table as the means of hooking into the kernel through the communication interface. Therefore, the hook object for level-3 is the system call table in the kernel. The best time to hook into the kernel is when the kernel is just unfolded in memory. Otherwise, once the kernel has reached a certain stage and activated its self-protection mechanism, it will be very difficult to tamper with the kernel. Therefore, the code that operates the kernel unfolding must be hooked. That is, the hook object for level-2 is the kernel image self-extracting code. Since the kernel image self-extracting code is bound to the kernel to form the kernel image, to hook into the kernel image self-extracting code, we must wait until the kernel image is loaded into memory. Therefore, the kernel image loading code needs to be hooked. Thus, the hook object for level-1 is the kernel image loading code.
