Tough One

A long time ago I played Ultima Online, while I played people created applications that would allow you to do specific things in the game. Like arm your weapon or cast a spell. Anyways I have always been really currious how people interfaced with the game. I mean how can you tell the game to equip a weapon. I dont even have an idea of where to start looking to learn something like that. Well If anyone has any suggestions of where to look or where to start I would really appriciate them.
Thank you,

The first place to look is the homepage of teh producer. If that fails, do a google search for it. You should be able to find some info on some web page. There always is.

I know a little bit about how they do this.

There are two basic things that these programs do to interface with Ultima or any other "hacks" for Online games.

The first is faking packets. What the programmer does is sniff the packets that Ultima sends back and forth to and from the server when he does certain actions. He then designs a program that can generate these packets itself and sent them to the Ulitima Server. This tricks the server into thinking the player actually did the actions, and then the server sends the appropriate packets back to the client game to display the results.

The other thing that often works in conjunction with the packet faking is doing things to the memory space the game application uses. The program can "hack" into the running application's in process memory and manipulate it, tricking it into behaving as if the program itself did a certain method call, etc.

Your best start would be with packet faking, and to do that get some sort of freeware packet sniffer. Hopefully you know a bit about the TCP/IP protocol and can interpret the data from the packets, then create your program from that.

Good luck.

hmm sounds like fun, thanks for the tip

I've seen stuff like this in Diablo 2 on Open Battle.net (a while ago). You would run this program that could see other people's stats and then you could actually trick their client into thinking their character's stats had changed giving you the ability to change their stats. It was a very nasty Diablo 2 hack. I was happy to see it go. It's funney, Blizzard said Diablo 2 would be tougher to hack. Look where open bnet is now, lol.

Open BNet is easy to hack, closed is hard.

That's an understatement. I don't think I've ever played a game that was hacked so much. It was actually fun trying to hack and figure out the game awhile ago but now it's just gone too far.

does anyone know where to get a packet sniffer so i can see the packets being sent from and to internet explorer??

If you're using Windows XP, packetmon from AnalogX is pretty good (it's free). If you have another OS, you can try Ethereal(free and opensource). It's one of the best out there. You'll need the latest copy of WinPcap (if your using Windows) to use it. Links are bellow:

Diablo 1.

Id also like to mention that packet faking is pretty much a sure bet to be in direct violation of your EULA.

oh, dont worry, none of us are planning on playing around with the idea at all. It is just an interesting idea, for our educational experince . . . right guys?

Lol, I'm sure the guys on open bnet have violated their EULAs into oblivion. Don't worry Zaei, I only used it on myself (it was the perfect tool for hacking memory resident stats). Blizzard is well aware of what goes on in open bnet and they haven't done much to stop it.

And Diablo 2 has it far worse than Diablo ever did (atleast on open battle.net). People don't even play the game anymore, they just see who can hack their characters the best.

Its not like a EULA is any sort of binding legal contract, so dont worry you are safe.

Until you are banned, of course =).

Blizzard could care less about what you do on Open bnet. However, once you start trying for Closed, they would probably come at you with an iron mallet.

Which is why Diablo 2 is still pretty good if you play in closed. I haven't seen too many attempts at doing any hacking on closed. It's amazing how many people still play that game on closed.

thanks, i always wanted to see the packets sent out by internet explorer!! thanks so much! and another question, how can i fake packets, like i found a packet being sent that i want to send it a couple of times... i need to fake the package.... or i can just use telnet, i think! please help!

hi!

You can use the winsock control to send a package

oops, stupid me :), i didn't think of that

Winsock control in C++? :eek:

Use plain winsock API.

Pretty Good Indeed
Quite Good
Very Good

I didn't say it was completly free of hacking. And besides, out of all the times I've played on closed I've never had any problems with hacking. Have you ever actually seen any of that stuff on closed? I doubt it even works.

Yeah, I've seen it around. Unique items that are the wrong type of equipment, runeword items with no runes in them, normal equipment with rare modifiers...eep. I'm waiting for the patch, but I bet it won't fix it all.

Geez, it's a good thing I stoped playing when I did. Didn't know it has spread into closed.
