Quickly brute forcing syscall indices in Windows

I've seen sites with lists of syscall indices like j00ru's and always hoped for a way to obtain syscalls programatically, and I finally figured it out.

THREADINFOCLASS enum value ThreadLastSystemCall was introduced at some point, and there's pretty limited documentation on how it's supposed to work so I thought I'd put it out there for all to see.

#include "stdafx.h"
#include "syscalls.h"
#include "ntdll_syscall_list.h"

BOOL GetFunctionSystemCallIndex(PVOID pFunctionAddress, DWORD *dwSyscallIndex)  
    if (!dwSyscallIndex)
        return FALSE;

    typedef NTSTATUS(*fn_t)(ULONG_PTR a1, ULONG_PTR a2, ULONG_PTR a3);
    typedef struct _THREAD_BRUTE_PARAMS
        fn_t proc;
        int state;


    params.proc = (fn_t)pFunctionAddress;
    params.state = 0;

    auto thread_fn = [](LPVOID lpParam) -> DWORD
        THREAD_BRUTE_PARAMS *pparams = (THREAD_BRUTE_PARAMS *)lpParam;

            // On x64 values are passed via registers first
            // then stack.
            // Shouldn't matter if this is incorrect since kernel shouldn't fault.

                volatile unsigned char stack_filler[0x4000];

                pparams->proc(0, 0, 0);
            __except (EXCEPTION_EXECUTE_HANDLER)
                // Exception loop
                pparams->state = 3;

            pparams->state = 1;
        } while (true);

        return 0;

    HANDLE hThread = CreateThread(0, 0, thread_fn, &params, 0, 0);
    if (hThread)
        HANDLE hWaitObject;
        RegisterWaitForSingleObject(&hWaitObject, hThread, [](PVOID lpParameter, BOOLEAN TimerOrWaitFired) -> VOID {
            // If we timed out...
            if (TimerOrWaitFired)
                THREAD_BRUTE_PARAMS *pparams = (THREAD_BRUTE_PARAMS *)lpParameter;

                pparams->state = 2;
        }, &params , 5, WT_EXECUTEONLYONCE);

        while (true)
            if (params.state == 0)

            if (params.state > 1)

            // Once the state is not zero, 
            // the syscall index is valid.

            memset(&sys, 0, sizeof(sys));

            ULONG u;

            NTSTATUS status = NtQueryInformationThread(hThread, ThreadLastSystemCall, &sys, sizeof(THREAD_LAST_SYSCALL_INFORMATION), &u);
            if (status == 0)
                *dwSyscallIndex = sys.SystemCallNumber;
                // STATUS_NOT_IMPLEMENTED
                // Your OS doesn't support this API my dude.
                if (status == 0xC0000002)

        TerminateThread(hThread, 0);

        if (*dwSyscallIndex)
            return TRUE;

    return FALSE;

void dump_ntdll_functions()  
    HMODULE hNtDll = LoadLibrary(L"ntdll.dll");
    if (!hNtDll)
        printf("[!] ERROR: Unable to get ntdll.dll base address.\n");

    for (size_t i = 0; ntdll_functions[i] != 0; i++)
        PVOID pProc = GetProcAddress(hNtDll, ntdll_functions[i]);
        if (!pProc)
            printf("[!] ERROR: Unable to get [%s] address.\n", ntdll_functions[i]);

        LARGE_INTEGER frequency;
        LARGE_INTEGER start;
        LARGE_INTEGER end;
        double interval;


        DWORD dwIndex = -1;
        if (!GetFunctionSystemCallIndex(pProc, &dwIndex))
            printf("[!] ERROR: Failed to get syscall index for [%s]\n", ntdll_functions[i]);

        interval = (double)(end.QuadPart - start.QuadPart) / frequency.QuadPart;

        if (dwIndex != -1)
            printf("%s index: 0x%X (Time: %f)\n", ntdll_functions[i], dwIndex, interval);

int main()  

    return 0;

I use a few weird tricks here. Functions that transition to kernel mode via syscall are all X64-style "fastcall", and if they fault, no big deal. So I call them all with invalid parameters because even if the function fails, I'm still getting the syscall index.

I haven't and probably won't provide a method of getting X86 syscalls, but considering there likely won't be any new X86 operating systems (syscall indices for WOW64 syscalls is same as X64) you can safely use already documented syscall indices (or rewrite this slightly)

The result of this is:
