Packet Type 15000?

Hi,

Anyone know what this packet is for? It looks like it's full of a random mess.

Im pretty certain thats not a valid packet type, unless you wanna post a dump of it so that we can take a look at it.

Code:

Server -> Client - Type:0x3a98 Size:38
 >1E00983A B900F433 43771E1D EE812EE4< ...:...3Cw...... 00000000
 >901AE7E8 FC152355 ACCE0000 00005451< ......#U......TQ 00000010
 >53657276 6572<                       Server           00000020

Client doesn't ever seem to respond to it, but there are a lot of them, even just standing still doing nothing. I thought it might be related to the 1022 (switch 56) packets, if you know what I mean. Data in it is different every time, most likely some kind of cypher?

Looking through my packet log i noticed the first 2 bytes after the type always has the high order byte as 0 (assuming the value is 16 bit) but the low order byte can be anything from 00-ff. Last 4 bytes are always 0's.

Is this on the latest client?

Yes, i just grabbed that packet literally 10 minutes ago.

Doesn't seem to effect the bot-check as far as I can see (i have blocked it and not been bot-jailed), but I'm getting worried it's a "delayed" detector. Similar to what WoW does, lets them compile a list of botters then ban-wave them all.

I'd crack open OlyDbg and try to see what the client was doing with it if I had better debugging skillz, but my experience in that area is very limited.

I think it's an anti-private server packet. Kind of the reverse of a client check, a server verifier. Could be wrong though but I can't see what else it could possibly do.

Have you checked if there is any response back to the server with the packet type?

If not, then you're probably right about it's a server identifier.
