tinjector's Issues

Process Crash after successfull injection

Hello, first of all thank you for your contribution with this project im here to report an issue when you map.

The dll with Manual Map ThreadHijacking inject successfully and no issues if you just call a message box or something like that, hoewer if you create a thread or hook a function on the injected process this one will freeze and crash, to make things clear if you don't do anything more than calling a simple messagebox or AllocConole everything will be fine but you can't do anything more, no createthread and no hooks (no matter what kind of hooks if detours or not)

Here ill leave an example code im doing to test it.

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

void thstuff()//if this get called by createthread will crash the process
{
    AllocConsole();
    FILE* pFile = nullptr;
    freopen_s(&pFile, "CONOUT$", "w", stdout);

    printf("testest\r\n");

    while (true)
    {
        printf("loop\r\n");
        Sleep(100);
    }
}

BOOL APIENTRY DllMain( HMODULE hModule,
                       DWORD  ul_reason_for_call,
                       LPVOID lpReserved
                     )
{
    switch (ul_reason_for_call)
    {
    case DLL_PROCESS_ATTACH:
        CreateThread(nullptr, 0, (LPTHREAD_START_ROUTINE)thstuff, 0, 0, 0);//if we create a thread will crash once called otherwise no crash.
        break;
    }
    return TRUE;
}
