Description: 对付ring0 inline hook的基本思路是这样的，自己写一个替换的内核函数，以NtOpenProcess为例，就是 MyNtOpenProcess。然后修改SSDT表，让系统服务进入自己的函数MyNtOpenProcess。而MyNtOpenProcess要做的事就是，实现NtOpenProcess前10字节指令，然后再JMP到原来的NtOpenProcess的十字节后。这样NtOpenProcess 函数头写的JMP都失效了，在ring3直接调用OpenProcess再也毫无影响。-Ring0 inline hook to deal with the basic idea is that the replacement of their own to write a kernel function to NtOpenProcess for example, is MyNtOpenProcess. And then amend the SSDT table, so that system services into its own function MyNtOpenProcess. And MyNtOpenProcess to do is realize NtOpenProcess the first 10-byte instruction, and then JMP to the original NtOpenProcess the Cross Festival. This NtOpenProcess function of the JMP are the first to write a lapse in ring3 no longer directly call OpenProcess no impact. Platform: |
