Sample Code:

    LPVOID mem;
    //virtualallocexnuma is used for bypass sandbox. As this api is not present inside sandox environmrnt.
    mem = VirtualAllocExNuma(GetCurrentProcess(), NULL, 1000, MEM_COMMIT | MEM_RESERVE, 0x4, 0);

    // if inside sandbox then virtualallocexnuma will fail and mem will be null. if inside normal machine then it will return address within current process adress space.
    // Therefore effectively we are preventing execution of out exploit in AV's sandbox
    if (!mem)
    {
        exit(0);
    }
