I make simple a UWP app and a desktop app. This code inject the ConsoleApplication1.dll file to the desktop is normal, but I cannot inject to UWP app.
I have two question :
Why this code cannot inject to UWP app?
and How fix it?
This code inject a DLL file
#include "pch.h"
#include <vector>
#include <string>
#include <windows.h>
#include <Tlhelp32.h>
using std::vector;
using std::string;
int main(void)
{
while (true)
{
vector<string>processNames;
PROCESSENTRY32 pe32;
pe32.dwSize = sizeof(PROCESSENTRY32);
HANDLE hTool32 = CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS, NULL);
BOOL bProcess = Process32First(hTool32, &pe32);
if (bProcess == TRUE)
{
while ((Process32Next(hTool32, &pe32)) == TRUE)
{
processNames.push_back(pe32.szExeFile);
if (strcmp(pe32.szExeFile, "ConsoleApplication4.exe") == 0 || strcmp(pe32.szExeFile, "UWP.exe") == 0)
{
printf("Hooked %s, %d
", pe32.szExeFile, pe32.th32ProcessID);
char* DirPath = new char[MAX_PATH];
char* FullPath = new char[MAX_PATH];
GetCurrentDirectory(MAX_PATH, DirPath);
sprintf_s(FullPath, MAX_PATH, "%s\..\ConsoleApplication1\ConsoleApplication1.dll", DirPath);
FILE *pFile;
if (fopen_s(&pFile, FullPath, "r") || !pFile)
{
OutputDebugString("[Hook] File name or file does not exist");
OutputDebugString(FullPath);
return -1;
}
fclose(pFile);
HANDLE hProcess = OpenProcess(PROCESS_ALL_ACCESS, FALSE, pe32.th32ProcessID);
LPVOID LoadLibraryAddr = (LPVOID)GetProcAddress(GetModuleHandle("kernel32.dll"), "LoadLibraryA");
LPVOID LLParam = (LPVOID)VirtualAllocEx(hProcess, NULL, strlen(FullPath), MEM_RESERVE | MEM_COMMIT, PAGE_READWRITE);
bool result = WriteProcessMemory(hProcess, LLParam, FullPath, strlen(FullPath), NULL);
CreateRemoteThread(hProcess, NULL, NULL, (LPTHREAD_START_ROUTINE)LoadLibraryAddr, LLParam, NULL, NULL);
CloseHandle(hProcess);
delete[] DirPath;
delete[] FullPath;
OutputDebugString("[Hook] Hooked success");
system("pause");
return 0;
}
}
}
CloseHandle(hTool32);
}
return 0;
}
Thanks
