How to change your Player-ID and GUID? Need help
« on: September 03, 2010, 08:07:53 pm »
Hoi, I need to change my Player ID and GUID. The GUID get created from the CD-Key, right? I do have a few "good" CD-Keys, so Im fine on that side.

However, how do you change the Player ID? I used the forum search, and only came up with dead links and a program that wont work with BE-enabled servers.

Thanks in advance.

To change your player ID, you have to figure out what's being sent to the server, and then change it to whatever you want it to be.

To do this, you'd have to use C++ and make a hook of your own, or you could do it the ghetto way, and change the value before it leaves your computer, ;-).

The packet containing the RSA key for bin.pbo contains a hash of made up of your key with another (seemingly) random "authentication" string.

E.g. 0de7ed97545febd23dd38e23d3600e355e4471e3594477f96c03aef8dfdd43d664e911c

The bold part of the hash is based on your key while the non-bold seems to be random each time. Changing the bold part to something that doesn't conform to the algorithm returns "Invalid key" and changing the non-bold returns "Invalid authentication".

When you finally get in the server, a packet is sent beginning with BE containing your GUID. Changing this results in "Client not responding" after about 30 seconds and if you join a server your already banned on, you stay banned. Probably because it also checks the above CD hash.

I guess if you got someone elses CD hash (the bold part), replaced your own with theirs in WPE while leaving the second half untouched so it correctly generates the "authentication" string AND THEN replace your GUID in the BE packet with the one attached to the spoofed CD hash, you could change your "hardcoded" identity. You would also need to send your "heartbeat" packet, as mrmedic calls it, so the server still thinks your BE client is still running correctly.

Just a thought.

Just a little note that may help:

That is already in hex. If you put it into ASCII you may see a pattern. Or you may not.

One small think I noticed is that the bold part is generaly symbols while the secound part is generaly letters. Two different ends of the table.

Wait, isn't that the Gamespy cd-key auth?

It's pretty well documented on Luigi's site.

Because it takes the key off your comp and sends it, don't you just have to modify the one on your comp?

I understand that the server sends a string to you, adds your key and IP to it, then sends it back. After that its sent to the master server.

But back to my first point:

Surly it would be easier to modify the key while its still on your PC?

orly? captan obvious got you, lolz. what you say is the same as changing the key in registry - no hacking involved. problem is, where to get different valid key? .... :D


but thanks you guys, for documeting what i said long ago but allknowing Z couldnt admit. Pride, how dare u suggest gamespy sdk is involved in thsi process?!!!

read this fail post for reference:
So called "bad keys" are hard coded in the games EXE via a patch so use ANY key that is withen the "good" range.
GameSpy checks NOTHING for this game (they are not paid...they don't work for free).

There is another way to connect to a server if GameSpy is involved....and you don't even need a key at all for games that GS does check keys.
Clearly I am not passing that information around to anyone as it would end all games,but the exploit has been with GS from it's start.

all blah blah as usual.. i tried this lots of times and only result i ever get is that you can only use real (bought for money, you know) keys on multiplayer. so yea, here you have it Z.

When testing DARKY's befor it was decide not to host it here...the keys the team used -online- were generated,not bought.  :icon_magician
