这里主要是利用NTDLL.dll中未文档化的API:

RtlAdjustPrivilege

来实现提权、自动关机的功能。

RtlAdjustPrivilege定义如下:

NTSTATUS RtlAdjustPrivilege
(
ULONG Privilege,
BOOLEAN Enable,
BOOLEAN CurrentThread,
PBOOLEAN Enabled
)

参数含义如下:
Privilege [In] Privilege index to change.                        
// 所需要的权限名称,可以到MSDN查找关于Process Token & Privilege内容可以查到

Enable [In] If TRUE, then enable the privilege otherwise disable.
// 如果为True 就是打开相应权限,如果为False 则是关闭相应权限

CurrentThread [In] If TRUE, then enable in calling thread, otherwise process.
// 如果为True 则仅提升当前线程权限,否则提升整个进程的权限

Enabled [Out] Whether privilege was previously enabled or disabled.
// 输出原来相应权限的状态(打开 | 关闭)

#include <iostream>
#include <windows.h>
#include <string> using namespace std; const unsigned long SE_DEBUG_PRIVILEGE = 0x13;
typedef int(_stdcall *_RtlAdjustPrivilege)(int, BOOL, BOOL, int *);
typedef int(_stdcall *_ZwShutdownSystem)(int); int main(int argc, char* argv[])
{
HMODULE hNtDll = LoadLibrary("NTDLL.dll");
if (!hNtDll)
cout << "Error.." << endl;
_RtlAdjustPrivilege pfnRtlAdjustPrivilege = (_RtlAdjustPrivilege)GetProcAddress(hNtDll, "RtlAdjustPrivilege");
_ZwShutdownSystem pfnZwShutdownSystem = (_ZwShutdownSystem)GetProcAddress(hNtDll, "ZwShutdownSystem"); int nEn = ;
pfnRtlAdjustPrivilege(SE_DEBUG_PRIVILEGE, TRUE, FALSE, &nEn);
pfnZwShutdownSystem(); return ;
}
