Sorry if i bug you MADCATX, Can you explain if possible, how capture with authenticated information would help? I'm just curios, if that will be efficient information to emulate BAttle.net server, or there must be custom API to be written or such in order to emulate ? As far as i understand Blizzards side server currently "hosting" maps and synchronize players in the game ? How in this case capture authentication traffic would help ? Which kind of traffic is expected to be captured and what needs to be performed? Reason i'm asking is We should educate masses and have them do it without risk of them loosing their keys - everyone is suspicious about their authentication data.  Please share your mind with us. Thank you !
First of all, if someone want to submit this data, they should change their password before doing so. It's not the only packets I ask, they should also load some map. Packets dumps will play some scenario of interacting with battle.net between client and server, that we can repeat. I don't know if there is some interaction between the client and server in the game it self with only one player presented. If there is, then it will be hard to repeat. Everything else can be done by repeating the packets scenario.
If someone cracked the battle.net.dll, and has data mined information about packet structures, then it will be more valuable then packets dumps.

MADCATX, are you reading the package header/information or just sending what you captured with wireshark without knowing what it means? Can you please post what you know about the protocol here.

I try to differentiate packets with answers to the same command, if they differ then  there is simething to do with it.
I've found that packet coming from server to auth command always have different bytes, starting from byte 46, so this packet have some header information and the rest is the seesion key.
US auth header:
420861757468005553428f52906a2c85b416a595702251570f96d3522f39237603115f2f1ab24962043c500100
EU auth header:
421061757468004555428f52906a2c85b416a595702251570f96d3522f39237603115f2f1ab24962043c500100
Possible differences EU in place of US and so on (4555=EU)(5553=US)...
However EU session key is longer then US by 554 bytes. You also can't login to US server with EU client and vice versa. What is stored in this 554 bytes I do not imagine.

Bad server means the you use US client, but send EU auth data, I'm currently downloading EU client to test it...

Now I'm no brainiac at this stuff, & what I'm saying may be completely wrong... But what if the file you are tinkering with isn't the correct file? I played WOTLK before it was released, on a private server it was way to easy. I think they may try to make this one harder. Now you say that it keeps connecting to there server even after you put yours in. What if they hid the actual file somewhere else that connects to the server and the one that you guys are messing with is just a decoy? Again I may be completely off but just trying to help out anyway possible!! Hope all is going well!!

I want to marry you! ^^

Now, with this info, will we be able to successfully emulate battle.net?
