so i created a dll injector and a dll that displays a messagebox.
Then i tested it on csgo and it worked once but then it never worked again no matter what i did.

how can i fix it?

thanks for the help!

Might want to post your sourcecode here.

INJECTOR

Code

#include <iostream>
#include <Windows.h>
#include <string>
#include <fstream>
#include <TlHelp32.h>

using namespace std;

void error(const char* title, const char* msg) {
    MessageBox(0, (LPCSTR)msg, (LPCSTR)title, 0);
    exit(-1);
}


BOOL __stdcall GetProcessID(const char* window_title, DWORD &proc_id)
{
    HWND hwnd = FindWindow(NULL, (LPCSTR)window_title);
    if (hwnd == NULL)
        error("Finding window", "Couldn't find window");

    if (!GetWindowThreadProcessId(hwnd, &proc_id))
        error("Process ID", "Couldn't find process ID");

    cout << "PROCESS ID: " << proc_id << endl;
    return TRUE;
}

int main()
{

    DWORD proc_id = NULL;
    const char* window_title = "Spotify Free";
    const char* dllName = "Test.dll";
    char dllPath[MAX_PATH];

    if (!GetFullPathName(dllName, MAX_PATH, dllPath, nullptr))
        error("DLL search", "Couldn't find DLL");

    GetProcessID(window_title, proc_id);
    if (proc_id == NULL)
        error("Process ID", "Couldn't find process ID **ERROR**");

    HANDLE h_process = OpenProcess(PROCESS_ALL_ACCESS, NULL, proc_id);
    if (h_process == NULL)
        error("Process Handle", "Couldn't find process HANDLE");

    void* allocated_memory = VirtualAllocEx(h_process, nullptr, sizeof(dllPath), MEM_RESERVE | MEM_COMMIT, PAGE_READWRITE);
    if (!allocated_memory)
        error("Allocated memory", "Bad allocated memory");

    cout << "ALLOCATED MEMORY addr: " << allocated_memory << endl;

    if (!WriteProcessMemory(h_process, allocated_memory, dllPath, MAX_PATH, NULL))
        error("Writing process memory", "Error writing process memory");

    HANDLE h_thread = CreateRemoteThread(h_process, nullptr, NULL, LPTHREAD_START_ROUTINE(LoadLibraryA), allocated_memory, NULL, nullptr);
    if (h_thread == NULL)
    {
        cout << GetLastError() << endl;
        error("Creating remote thread", "Error creating remote thread");
    }
    CloseHandle(h_process);
    VirtualFreeEx(h_process, allocated_memory, NULL, MEM_RELEASE);
    MessageBox(0, "Successfully injected!", "Success!", 0);
}

DLL:

Code

// dllmain.cpp : Defines the entry point for the DLL application.
#include "pch.h"


BOOL APIENTRY DllMain( HMODULE hModule,
                       DWORD  ul_reason_for_call,
                       LPVOID lpReserved
                     )
{
    switch (ul_reason_for_call)
    {
    case DLL_PROCESS_ATTACH:
        MessageBox(0, "Hello from inside CSGO!", "MaMan!", 0);
    case DLL_THREAD_ATTACH:
        MessageBox(0, "Hello from inside CSGO! - THREAD", "MaMan!", 0);
    case DLL_THREAD_DETACH:
    case DLL_PROCESS_DETACH:
        break;
    }
    return TRUE;
}

You restarted CS:GO in-between your attempts at injecting, right?

[HardStoN]

yes i did. everytime injection didnt work i closed the injector and csgo then opened up csgo again and the injector and ran the injector and still nothing works...

[incognito04]

You should use WaitForSingleObject before closing the threads handle. I've heard something about vac adding some protection around loadlibrary so that could be the case.

vac did indeed got recently updated

This. Also OP look at manual mapping. For a ghetto fix just inject your dll from windows subfolder lol
