Hi everyone, how're u guys doing.
So I'm playing an mobile chinese online game and I began to do some research month ago just to hack it.
At first, the method I use is packet editing. I set up a proxy server (CCproxy) in VM (VMLiteXPmode), and proxifier setting to redirect all my network to come through that proxy server. After that, I use WPE Pro to capture packet and attempt to resend packets. However the packets are all encrypted in MD5 and CRC32 (checksum) so it doesnt work.
So I use Clutch to get a binary cracked of the game. then I put it into IDAPro and found out something very interesting
Input MD5 : 8127305391F36204C9AB217D8C3297F0 Input CRC32 : A42A2DCA
And with the IDA, I think I have found the packet encryption method. So I can decrypt packet I got in WPE, and resend it. However I think I still got a very long way to go from here.
So anyone can give me a bit suggestion of what I should do next
Thank you very much
