How to bypass debugging

On a whim, I’m looking for new wallpaper. I usually go with black backgrounds, with some colored accents. Since there will be icons on the desktop, other color schemes would make them unclear.

After pondering the assembly code, I couldn’t understand it. I tried asking AI for an explanation of the instructions, but they didn’t explain the context. It must be a specific scenario where these instructions are used; this isn’t typical code.

A search engine is better now; my assembly knowledge is lacking

Please provide the Chinese text you want me to translate. I am ready when you are.

Assembly code

PUSHFD
MOV DWORD PTR [ESP],0X100
POPFD

Practical application scenarios

bool IsDebugged()
{
    __try
    {
        __asm
        {
            pushfd
            mov dword ptr [esp], 0x100
            popfd
            nop
        }
        return true;
    }
    __except(GetExceptionCode() == EXCEPTION_SINGLE_STEP
        ? EXCEPTION_EXECUTE_HANDLER
        : EXCEPTION_CONTINUE_EXECUTION)
    {
        return false;
    }
}

Explanation

Because if we track the code, this flag will be cleared by the debugger, so we won’t see this exception

In practical testing, skipping the detection and debugging functions results in undetected debugging; it is only detected when entering the execution of the detection function. (Information gathered, not yet practically verified.)
