C/C++ 提权与强制卸载DLL

权限提升

#include <Windows.h>
#include <stdio.h>

BOOL SetPrivilege(LPCTSTR lpszPrivilege, BOOL bEnablePrivilege)
{
	TOKEN_PRIVILEGES tp;
	HANDLE hToken;
	LUID luid;

	OpenProcessToken(GetCurrentProcess(), TOKEN_ADJUST_PRIVILEGES | TOKEN_QUERY, &hToken);
	LookupPrivilegeValue(NULL, lpszPrivilege, &luid);
	tp.PrivilegeCount = 1;
	tp.Privileges[0].Luid = luid;

	if (bEnablePrivilege)
		tp.Privileges[0].Attributes = SE_PRIVILEGE_ENABLED;
	else
		tp.Privileges[0].Attributes = 0;

	AdjustTokenPrivileges(hToken, FALSE, &tp, sizeof(TOKEN_PRIVILEGES), (PTOKEN_PRIVILEGES)NULL, (PDWORD)NULL);
	if (GetLastError() == ERROR_NOT_ALL_ASSIGNED)
		return FALSE;
	else
		return TRUE;
}
int main()
{
	SetPrivilege(SE_DEBUG_NAME, TRUE);
	return 0;
}

强制卸载DLL

#include <Windows.h>
#include <stdio.h>
#include <TlHelp32.h>

	hSnapshot = CreateToolhelp32Snapshot(TH32CS_SNAPMODULE, dwPID);
	bMore = Module32First(hSnapshot, &me);
	for (; bMore; bMore = Module32Next(hSnapshot, &me))
	{
		/*
		
		if (!_tcsicmp((LPCTSTR)me.szModule, szDllName) || !_tcsicmp((LPCTSTR)me.szExePath, szDllName))

			bFound = TRUE;
			break;
		}
		*/

	}
	if (!(hProcess = OpenProcess(PROCESS_ALL_ACCESS, FALSE, dwPID)))
		return FALSE;

	hModule = GetModuleHandle(L"kernel32.dll");
	pThreadProc = (LPTHREAD_START_ROUTINE)GetProcAddress(hModule, "FreeLibrary");
