How to find the pointer to the D3D9 device by lauwy

This tutorial is by lauwy from MPGH!!!

First download the test envoirment,
Edit the plugin path
Restart olly
load this in ollydbg

Press ctrl a to scan the file
Click on the run button in the top of olly 3x

Click the richt mous button , searth for all intermodulars class.

Find somting like this:
d3d9.Direct3DCreate9

Dubbel click on it,
We need the CALL under it:

Code:

0040315A  |. E8 7F700000    CALL <JMP.&d3d9.Direct3DCreate9>
0040315F  |. A3 10CE4000    MOV DWORD PTR DS:[40CE10],EAX //This is what we need, this is the IDirect3DDevice9 
00403164  |. 6A 38          PUSH 38
00403166  |. 8D45 BC        LEA EAX,DWORD PTR SS:[EBP-44]
00403169  |. 6A 00          PUSH 0
0040316B  |. 50             PUSH EAX
0040316C  |. E8 4F080000    CALL test9.004039C0

40CE10 points to the Createdivice,

40CE10 = [out, retval] IDirect3DDevice9 **ppReturnedDeviceInterface

Code:

HRESULT CreateDevice(
  [in]           UINT Adapter, //6
  [in]           D3DDEVTYPE DeviceType, //5
  [in]           HWND hFocusWindow, //4
  [in]           DWORD BehaviorFlags, //3
  [in, out]      D3DPRESENT_PARAMETERS *pPresentationParameters, //2
  [out, retval]  IDirect3DDevice9 **ppReturnedDeviceInterface //1
);

We need the pointer to CreateDevice, what do we know?
We know one part of CreateDevice, and we know that we need 6 x push, becouse CreateDevice has 6 "parts".
We need to find somting like this:

Code:

MOV EAX,DWORD PTR DS:[40CE10]

Change the addy to yours, this can be different!

Searth for this, I found this 2 times,

Code:

00403171  |. 83C4 0C        ADD ESP,0C
00403174  |. 8B4D 08        MOV ECX,DWORD PTR SS:[EBP+8]
00403177  |. A1 10CE4000    MOV EAX,DWORD PTR DS:[40CE10]
0040317C  |. 8D5D BC        LEA EBX,DWORD PTR SS:[EBP-44]
0040317F  |. 6A 01          PUSH 1 				//This needs to be somting with [40CE10]
00403181  |. 894D D8        MOV DWORD PTR SS:[EBP-28],ECX
00403184  |. 5E             POP ESI				
00403185  |. C745 C4 160000>MOV DWORD PTR SS:[EBP-3C],16
0040318C  |. 68 08CE4000    PUSH test9.0040CE08			
00403191  |. 53             PUSH EBX				
00403192  |. 6A 20          PUSH 20			
00403194  |. 51             PUSH ECX				
00403195  |. 8975 DC        MOV DWORD PTR SS:[EBP-24],ESI
00403198  |. 8975 D4        MOV DWORD PTR SS:[EBP-2C],ESI
0040319B  |. C745 BC 200300>MOV DWORD PTR SS:[EBP-44],320
004031A2  |. C745 C0 580200>MOV DWORD PTR SS:[EBP-40],258
004031A9  |. 8B10           MOV EDX,DWORD PTR DS:[EAX]
004031AB  |. 56             PUSH ESI				
004031AC  |. 6A 00          PUSH 0				
004031AE  |. 50             PUSH EAX				
004031AF  |. FF52 40        CALL DWORD PTR DS:[EDX+40]

This isn't create device, this is becouse the first command isn't the IDirect3DDevice9 here is EAX the IDirect3DDevice9, but they push 1, and that isn't EAX
Next!

Code:

00403470  |. A1 10CE4000    MOV EAX,DWORD PTR DS:[40CE10]
00403475  |. 50             PUSH EAX				//This is 40CE10 	|| [out, retval]  IDirect3DDevice9 **ppReturnedDeviceInterface
00403476  |. 8B08           MOV ECX,DWORD PTR DS:[EAX]
00403478  |. FF51 08        CALL DWORD PTR DS:[ECX+8]
0040347B  \. C3             RETN
0040347C  /$ 55             PUSH EBP				//2			||  [in, out]      D3DPRESENT_PARAMETERS *pPresentationParameters,
0040347D  |. 8BEC           MOV EBP,ESP
0040347F  |. 833D CCE14000 >CMP DWORD PTR DS:[40E1CC],0
00403486  |. 57             PUSH EDI				//3			||  [in]           DWORD BehaviorFlags,
00403487  |. 8B7D 08        MOV EDI,DWORD PTR SS:[EBP+8]
0040348A  |. 897D 08        MOV DWORD PTR SS:[EBP+8],EDI
0040348D  |. 75 11          JNZ SHORT test9.004034A0
0040348F  |. FF75 10        PUSH DWORD PTR SS:[EBP+10]		//4			||   [in]           D3DDEVTYPE DeviceType,		
00403492  |. FF75 0C        PUSH DWORD PTR SS:[EBP+C]		//5			||   [in]           HWND hFocusWindow,
00403495  |. 57             PUSH EDI				//6			||   [in]           UINT Adapter,
00403496  |. E8 550F0000    CALL test9.004043F0

Here is EAX, DWORD PTR DS:[40CE10] and it gets pushed at the top of the call, that is good

There are 6x push and the first is the IDirect3DDevice9

, this is createdevice!!!

To make every thing clear:
0x4043F0 is the "Pointer to the D3D9 device"

Going to find out how this is done in Crossfire, then I'm going to share that 2 If some one know how to do this, contact me. THen I make a tut and give you 80% of the credits

Share what you know (a)

woooooooooooo! very good tut help ful!

, I'm alway's here to share what I know (a).

Edit:
I could't find a tutorial for this, so I thought I make one my self

i wanna try this!

opss

Add Virus scans.

Virus scans....

VirusTotal - Free Online Virus, Malware and URL Scanner

Can't find more scanner that can scan so mutch files, why do we need here also scan't, that wasn't before :S.

If you don't trust this, download from my cshell tutorial ollydbg, and searth for the test9.exe on the site:

Test9.exe
http://www.mpgh.net/forum/207-combat...vironment.html

Olly:
http://www.mpgh.net/forum/242-crossf...shell-dll.html

Yes it is showen as a virus by some scan's becouse it is ollydbg xD so useless to add scanners to files like this xD

thank you very much bro this will help alot thanks bro
