windows 64位 系统非HOOK方式监控进程创建

以下内容参考黑客防线2012合订本354页

 

MSDN 原话:

The PsSetCreateProcessNotifyRoutineEx routine registers or removes a callback routine that notifies the caller when a process is created or exits.

NTSTATUS
  PsSetCreateProcessNotifyRoutineEx(
    IN PCREATE_PROCESS_NOTIFY_ROUTINE_EX  NotifyRoutine,
    IN BOOLEAN  Remove
    );

可以通过这个函数注册一个回调函数监控进程创建. 比hook方便很多.

对于CreateProcessNotifyEx:

VOID
  CreateProcessNotifyEx(
    __inout PEPROCESS  Process,
    __in HANDLE  ProcessId,
    __in_opt PPS_CREATE_NOTIFY_INFO  CreateInfo
    );

其中CreateInfo是

If this parameter is non-NULL, a new process is being created, and CreateInfo points to a PS_CREATE_NOTIFY_INFO structure that describes the new process. If this parameter is NULL, the specified process is exiting. 

空的时候表示进程退出, 非空时表示进程创建.并且里面:

typedef struct _PS_CREATE_NOTIFY_INFO {
  __in SIZE_T  Size;
  union {
    __in ULONG  Flags;
    struct {
      __in ULONG  FileOpenNameAvailable : 1;
      __in ULONG  Reserved : 31;
    };
  };
  __in HANDLE  ParentProcessId;  //创建者pid
  __in CLIENT_ID  CreatingThreadId;
  __inout struct _FILE_OBJECT  *FileObject;
  __in PCUNICODE_STRING  ImageFileName;//被创建进程完整路径
  __in_opt PCUNICODE_STRING  CommandLine;
  __inout NTSTATUS  CreationStatus;  //修改为错误的status禁止创建进程
} PS_CREATE_NOTIFY_INFO, *PPS_CREATE_NOTIFY_INFO;

 

测试结果:

 

 附上大佬的代码 (自己加了一些注释):

//下面2个函数声明后就能用
NTKERNELAPI PCHAR PsGetProcessImageFileName(PEPROCESS Process);
NTKERNELAPI NTSTATUS PsLookupProcessByProcessId(HANDLE ProcessId, PEPROCESS *Process);

PCHAR GetProcessNameByProcessId(HANDLE ProcessId)
{
    NTSTATUS st = STATUS_UNSUCCESSFUL;
    PEPROCESS ProcessObj = NULL;
    PCHAR string = NULL;
    st = PsLookupProcessByProcessId(ProcessId, &ProcessObj);
    if (NT_SUCCESS(st))
    {
        string = PsGetProcessImageFileName(ProcessObj);
        ObfDereferenceObject(ProcessObj);
    }
    return string;
}

VOID
NotifyCreateProcess(
    __inout PEPROCESS Process,//如果是创建(退出),则是被创建(退出)进程的exe名(不包括完整路径)
    __in HANDLE ProcessId,//如果是创建(退出)进程,则是被创建(退出)进程的pid
    __in_opt PPS_CREATE_NOTIFY_INFO CreateInfo//如果是创建进程,则里面包含被创建进程完整路径名
)
{

    if (CreateInfo)
    {
    //    DbgPrint("param ProcessId is %d\n", ProcessId); //被创建进程id
    //    DbgPrint("param Process is %s\n", PsGetProcessImageFileName(Process));
        DbgPrint("%s of who the pid is %d create process %wZ\n",
            GetProcessNameByProcessId(CreateInfo->ParentProcessId),
            CreateInfo->ParentProcessId,
            CreateInfo->ImageFileName);
        if (_stricmp("calc.exe", PsGetProcessImageFileName(Process)) == 0)
        {
            DbgPrint("forbidding start calc.exe!\n");
            CreateInfo->CreationStatus = STATUS_ACCESS_DENIED;
        }

    }
    else
    {
        DbgPrint("process %s exit\n", PsGetProcessImageFileName(Process));
    }
}
