Also, if you'd like to use PROCESS_ALL_ACCESS in OpenProcess, you could try this:
#include <cstdio>
#include <windows.h>
#include <tlhelp32.h>
void EnableDebugPriv()
{
HANDLE hToken;
LUID luid;
TOKEN_PRIVILEGES tkp;
OpenProcessToken(GetCurrentProcess(), TOKEN_ADJUST_PRIVILEGES | TOKEN_QUERY, &hToken);
LookupPrivilegeValue(NULL, SE_DEBUG_NAME, &luid);
tkp.PrivilegeCount = 1;
tkp.Privileges[0].Luid = luid;
tkp.Privileges[0].Attributes = SE_PRIVILEGE_ENABLED;
AdjustTokenPrivileges(hToken, false, &tkp, sizeof(tkp), NULL, NULL);
CloseHandle(hToken);
}
int main( int, char *[] )
{
EnableDebugPriv();
PROCESSENTRY32 entry;
entry.dwSize = sizeof(PROCESSENTRY32);
HANDLE snapshot = CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS, NULL);
if (Process32First(snapshot, &entry) == TRUE)
{
while (Process32Next(snapshot, &entry) == TRUE)
{
if (stricmp(entry.szExeFile, "target.exe") == 0)
{
HANDLE hProcess = OpenProcess(PROCESS_ALL_ACCESS, FALSE, entry.th32ProcessID);
// Do stuff..
CloseHandle(hProcess);
}
}
}
CloseHandle(snapshot);
return 0;
}
