I am working with Mr. Florian0 trying to spoof packets from AgentServer to Gameserver. So far, we are able to make Gameserver start listening on a different port, so we can then bind the original port with an analyzer and redirect it to the new port.
With it, we can tap into the communication between AgentServer and Gameserver, but this concept applies to any other module in Silkroad that receives its certification from another module (ehem, all of 'em).
Now, there are two big issues to attend:
1) The code is working, but messy, so, to organize it and make it easier we must refactorate it. But the "hard part" it's completed already, which was tricking the modules to bind another port
2) The second issue it's the packet parsing which I don't know if it is either malfunctioning or the packets from AS to GS are somethimes huge and repetitives.
It says VSRO, but it can be applied to any silkroad files
Due the fact that it modifies cert packet A003 on the fly to change the desired ports
Please, your help is needed since this is a whole new approach, we don't know yet what can we accomplish with this, but based on logic, we can be able to make the Gameserver do desired work's without needing to do a lot of ASM.
