As the title ,PEB In fact, there are many members that can be used to detect the debugger （ Although some of the original intention is not necessarily , But there will be fixed changes when being debugged ）, But in Win7 after , There are only two that can be used ：（ So is this a good thing or a bad thing ）
Both of the above come from _PEB Structure ：（ Here is 32 position ,64 We'll talk about it later ）

The general function is ：
Normal operation popup “ The program runs here ” Dialog box
Single out when being debugged “ Debugger detected ” And finish running
Be careful ： Experiment with the original OD It works
Let's talk about it x64 Under the _PEB structure ：

So just change the offset directly ？ Cough .... Surely not , as a result of vs stay x64 After compilation, it is no longer correct __asm{} Keywords recognized , If you want to continue using inline assembly , Some small configurations are needed ： Refer to this article .
x64.asm Reference code ：
We found that mov rax,gs:[60h] This line of code , Compare with the original mov eax, fs:[0x30] Offset by 0x30 Turned into 0x60, as a result of x64 Next _TEB Because of the different structure of ：（ As for the difference between registers, we won't discuss it here ）
