工作需要，想控制进程的创建，于是HOOK了ZwCreateProcess，后来发现xp和2003中创建进程的都用NtCreateProcessEx(参见[1]）。
但是ZwCreateProcessEx未被ntoskrnl.exe导出，用softice的ntcall命令也没有看到,网上也没有找到相关代码。没办法，跟踪ntoskrnl!ZwCreateProcess
>u ntoskrnl!ZwCreateProcessEx
_ZwCreateProcess
0008:804e7ae2 bb32000000 mov eax, 00000032
但是ZwCreateProcessEx有9个参数，最后一个未知，4字节，猜成HANDLE型。
原型如下：
typedef NTSTATUS (*NTCREATEPROCESSEX)(
OUT PHANDLE ProcessHandle,
IN ACCESS_MASK DesiredAccess,
IN POBJECT_ATTRIBUTES ObjectAttributes OPTIONAL,
IN HANDLE ParentProcess,
IN BOOLEAN InheritObjectTable,
IN HANDLE SectionHandle OPTIONAL,
IN HANDLE DebugPort OPTIONAL,
IN HANDLE ExceptionPort OPTIONAL,
IN HANDLE Unknown );
最终用硬编码HOOK 成功，代码如下：
#include "ntddk.h"
#include "stdarg.h"
#include "stdio.h"
#include "ntiologc.h"
#define DWORD unsigned long
#define WORD unsigned short

typedef NTSTATUS (*NTCREATEPROCESSEX)(

IN HANDLE Unknown );

curproc = PsGetCurrentProcess();
for( i = 0; i < 3*PAGE_SIZE; i++ )
{
if( !strncmp( "System", (PCHAR) curproc + i, strlen("System") ))
{
gProcessNameOffset = i;
}
}
}
BOOL GetProcessName( PCHAR theName )
{
PEPROCESS curproc;
char *nameptr;
ULONG i;
KIRQL oldirql;
if( gProcessNameOffset )
{
curproc = PsGetCurrentProcess();
nameptr = (PCHAR) curproc + gProcessNameOffset;
strncpy( theName, nameptr, NT_PROCNAMELEN );
theName[NT_PROCNAMELEN] = 0; /* NULL at end */
return TRUE;
}
return FALSE;
}

{

GetProcessName( aProcessName );
DbgPrint("rootkit: NewNtCreateProcessEx() from %s/n", aProcessName);
//DbgPrint("ok");
return OldNtCreateProcessEx(ProcessHandle,DesiredAccess,

}
NTSTATUS

IN PIRP Irp
)
{

IoCompleteRequest (Irp,

);
return Irp->IoStatus.Status;
}
VOID OnUnload( IN PDRIVER_OBJECT DriverObject )
{

_asm
{

MOV EAX, CR0 //move CR0 register into EAX
AND EAX, NOT 10000H //disable WP bit

}
(NTCREATEPROCESSEX)(*(((PServiceDescriptorTableEntry)KeServiceDescriptorTable)->ServiceTableBase + 0x32))=OldNtCreateProcessEx;
_asm
{
MOV EAX, CR0 //move CR0 register into EAX
OR EAX, 10000H //enable WP bit
MOV CR0, EAX //write register back

}
}
NTSTATUS DriverEntry( IN PDRIVER_OBJECT theDriverObject, IN PUNICODE_STRING theRegistryPath )
{
int i;
DbgPrint("My Driver Loaded!");
GetProcessNameOffset();
// Register a dispatch function
for (i = 0; i < IRP_MJ_MAXIMUM_FUNCTION; i++)
{
theDriverObject->MajorFunction[i] = OnStubDispatch;
}
theDriverObject->DriverUnload = OnUnload;
// save old system call locations
//OldNtCreateProcessEx=(NTCREATEPROCESSEX)(SYSTEMSERVICE(0x32));
OldNtCreateProcessEx=(NTCREATEPROCESSEX)(*(((PServiceDescriptorTableEntry)KeServiceDescriptorTable)->ServiceTableBase + 0x32));
_asm
{
CLI //dissable interrupt
MOV EAX, CR0 //move CR0 register into EAX
AND EAX, NOT 10000H //disable WP bit
MOV CR0, EAX //write register back
}

_asm
{
MOV EAX, CR0 //move CR0 register into EAX
OR EAX, 10000H //enable WP bit
MOV CR0, EAX //write register back

}
return STATUS_SUCCESS;
}
这样很不爽，每次都要这样看索引号，问了SOBEIT，可以通过从NTDLL中这样获取服务索引号：
来自rookkit:
#include <windows.h>
#include <stdio.h>
BOOL GetId( char *FuncName, ULONG *FunctionID )
{
//get the function's address
PBYTE Function = (PBYTE)GetProcAddress( GetModuleHandle( "ntdll.dll" ), FuncName );
/*
do some sanity checks,
make sure this function
has a corresponding kernel
level function
*/
*FunctionID = 0;
//func not found...
if ( Function == NULL )
{
return FALSE;
}
/*
77F5B438 B8 00000000 MOV EAX, _FUNCTION_ID_
77F5B43D BA 0003FE7F MOV EDX,7FFE0300
77F5B442 FFD2 CALL EDX
77F5B444 C2 1800 RETN XX
*/
//mov eax
if ( *Function != 0xB8 )
{
return FALSE;
}
/*
since the address of
the function which
actually makes the call
(SYSCALL) may change, we just
check for mov edx
*/
if ( *(Function + 5) != 0xBA )
{
return FALSE;
}
//call edx
/*if ( *(PWORD)(Function + 10) != 0xD2FF )
{
return FALSE;
}
//retn
if ( *(Function + 12) != 0xC2 )
{
return FALSE;
}*/
*FunctionID = *(PDWORD)(Function + 1);
return TRUE;
}
int main(int argc, char* argv[])
{
ULONG Id;
printf( "function name: NtCreateProcessEx/n" );
GetId( "NtCreateProcessEx", &Id );
printf( "function id: X/n", Id );
return 0;
}

这样也不爽，要从用户态传到驱动层不方便，最后，用这个代码：

上面的代码从驱动层加载NTDLL，再从输出表中找出函数地址，mov eax,[ID]对应的b8后面的字就是索引号，其实跟前一个代码作用是相似的，
只是驱动层没有LoadLibrary,只能这样解决了。将上面的代码整合起来就比较完善了，大家看着改吧。这里顺便把2003中的服务描述表发出来，希望对大家有帮助：
