There are many things you can do with Packet DASM, such as testing Servers for exploits by sending custom crafted game packets of your own! Because more and more gaming companies are switching to client - server based Software learning about packet disassembly is strongly recommended, especially if you're an aspiring game hacker, such as myself!įeel free to critique my work and if you feel something could be better explained by all means share your thoughts! I'm always willing to improve my game hacking skills! OR If I fudged up someplace don't hesitate to laugh at me! I feed off of you! :-p :6FAAD991 884C2400 mov byte ptr, cl Select Game.exe > Start capturing data Here are some of the other packet building routines that I found using the above search method:ĭ2Client.dll - Routine used to build ALL packets with a length of 3 bytes! :6FAAD3D3 C64424046C mov, 6C Find Text > Type: call 6FAAD850 > Find Next

The packet type for the client update is 0圆C and its routine can be found here in the D2Client.dll: If SoftICE pops up without you doing anything after setting a breakpoint at 6FC017BE, chances are your client is sending an auto-update out, which is on a timer! 6FC017BE is a very useful address to us! :-P For every action that you do in-game that sends ANY data what-so-ever to others SoftICE will pop up at 6FC017BE and you can view that packet in and length of that packet in AL or BL. Step 11.) Now, for testing purposes you can "bpx 6FC017BE" from SoftICE and preform various actions. We can now assume that the following is the syntax for toggling gear with the "w" key:Ħ0 Step 10.) After typing "d ecx" in SoftICE, you'll notice stores the following: stores the packet! In SoftICE type: d ecx Step 8.) Toggled my gear with the "w" key! Step 6.) From SoftICE's command line I type'd: bpx send Step 5.) Ctrl+D into SoftICE! -> addr Game Step 4.) Returned to my Diablo II LoD game. Step 3.) Loaded WSOCK32.dll in SoftICE's Symbol Loader. (Remember to load SoftICE first if you're on NT!) Step 2.) Next, I ran SoftICE's Symbol Loader. Step 1.) The first thing I did was fire up Diablo 2 LoD and joined/created a game. Here are some that are more commonly used: There are several ways to locate WSOCK32 send() functions within a game. So fair warning, if you aren't the type of person who can spend hours and hours, possibly even months, in game code trying to understand how it works you should bail out now! Making packet senders aren't for you! IE: Open Source or some other game hacker released a packet reference to decrypted data from his/her own efforts. The principles used in this tutorial can help aid you in your quest, but only to a certain degree most of the time locating packet building processes before they are encrypted require alot of time tracing AND guessing, especially if there isn't any documentation on the game code. It's just a matter of extra backtracing and stepping. Each game is different on how things are done, but because a packet is generated using an encryption technique within the game code it CAN be found and CAN be reversed.

I'm frequently asked how to decrypt packet data that is encrypted on some of these odd ball games, such as Prince of Qin Online and it's frustrating for me to give an answer to this question because of all the unknowns. This game does not use encrypted data packets for send(), in-game! Keep this in mind if you plan to apply this tutorial to games that are using encrypted packets in-game.

This tutorial will be very similiar to my previous one, but with a few different twists because the programmers of the new V1.10 patch have updated quite a few things in the packeting send()'ing process! Nothing that we can't overcome though! -)

Tools used: SoftICE, WDASM, DHack, Notepad, WPE Pro and a brain!įirst, this is the second tutorial I've written covering the topic of "Packet DASM" using Diablo II LoD as our game of choice to reverse engineer. Skills required: An understanding of SoftICE, x86 ASM and a brain! Main focus of this tutorial: To create a packet sender for Diablo II LoD V1.10 *AND* hopefully give you (The reader) a better understanding of what Packet DASM is and how to write your very own packet sender for D2 or other gaming titles! Type of tutorial: Advanced FYI (For Your Information)
