Hoking dll with ShadowDBG

Tools needed:

1. Unpacked game server
2. Shadow'sDBG or OllyDBG

The guide:

1. Load normal 1.00.16 game server on shadow or olly.
2. Search for free space on gameserver
3. Search in hex dump offset 006B3000
4. There write name of your dll
5. At game server free space write push 006B3000
6. At second line write call LoadLibraryA
7. Mov dword ptr ds:[006B3005], eax
8. Push [006B3007]
9. Push Eax
10. Call GetProcAddress
11. Call Eax

FAQ:

1. What is free space? INT OR DB 00

About offsets

1. 006B3000 - Name of your dll
   
2. 006B3005 - Free offset
   
3. 006B3007 - Name of your PROCESS
   

Look:

PHP Code:

---

push 006B3000
call LoadLibraryA
Mov dword ptr ds:[006B3005], eax
Push [006B3007]
Push Eax
Call GetProcAddress
Call Eax

2nd part

this is great 10/10 is the first tutorial for newbie coders what i understand it :-P

i am newbie at asm too ;)

Thanks alot, nice guide =D
Are you going to keep doing guides like this? I hope you do^^

good job XD...

Nice :D only one question... how do I save it lol sorry im New.

This it`s a partial hook

Only partial? when I added my dll to the gameserver and i loaded gameserver it crashed, couldnt load. I dunno if i saved it right either ^^.

To save:
Right click > Copy to executable > All modification > Copy All > Right click > Save file

Thanks :D so if I follow that guide I can hook the dll from Holy's npc gaurd release? Or is there something else I must do.

here is a full guide XD http://forum.ragezone.com/f196/guide...server-172902/

Code:

---

Load normal 1.00.16 game server on shadow or olly.
Search for free space on gameserver
Search in hex dump offset 006B3000
There write name of your dll
At game server free space write push 006B3000
At second line write call LoadLibraryA
