Re: Issue with using Ollydbg with ROM

I figure I'd continue to update this on some of my findings...incase anyone finds a way to chime in.

After further probing, I have come to a few realizations(referring to the picture in the above post)

The above cases have to do with the general handling of packets. The packets are fed through the ...

Re: Issue with using Ollydbg with ROM

Okay so I managed to trace the function back to where it is called from...
Though it seems every single thing I follow backwards from this point has to do with game functions other than the packets. Typically when I have a breakpoint on the packet-related functions, the game will only break when I ...

Re: Issue with using Ollydbg with ROM

Good Catch, that off the top of your head haha c:?

I stumbled upon that 0x6EBD60 SUB ESP,1C earlier and did a lot of breakpoint and follow play with it but I couldn't find it to anywhere unencrypted. As of this point I'm just lost and taking shots in the dark hoping I get lucky.. :/. I feel like ...

Re: Issue with using Ollydbg with ROM

Oh when you said scroll up I figured you meant an amount greater than the 5 lines of the function :p.

Here's a screen shot of where I'm at now. I don't see the CALL FROM .... anywhere. I also have breakpointer'd and followed each piece connected to this and none lead to any unencrypted text.

Re: Issue with using Ollydbg with ROM

About 5 instances came up. Break-pointing the 3rd one causes the game to pause(for the break point) every time I send something. All this did was show me the spot in the disassembler that I already knew WSASend was being called. From that single point I probably tried to break point the next 100 ...

Re: Issue with using Ollydbg with ROM

Hi :),

Ultimately my end-goal is to hook the point right before the packets are encrypted so perhaps I can step in and modify them before they are encrypted. The client I find has a lot of checks in it preventing you from modifying certain values then sending them. Modifying these values then ...

Issue with using Ollydbg with ROM

I have been trying to figure out how I can use Ollydbg with ROM to try to find where the Winsock Send function is called, so I can hopefully locate packet data before it is encrypted. I originally tried modifying the packets with WPE but soon realized they're encrypted.

I've read around that if you ...
