I'm an eAthena developer long time ago and currently using rAthena, but I am not active in forums (just stalking ) Anyway I want to create my own game guard protection using my programming skills. I have done my research and I think its not enough. I know how to configure/edit function in rAthena's server-side for my future development on client-side. Every suggestion will be appreciated! Questions: How to start with ragexe? (e.g. How to read my DLL's function in Client.exe) Types of hacking tools? (e.g. WPE/RPE), I don't know the other common hacking tools Is this the right thread for this topic? Please support me!

To make the GRF save you would compress and encrypt the grf files. You would replace the cps.dll inside the kro client. There is a C++ Project which already is replacing the cps.dll. But it is not encrypting or crypting it. Do you programm in C++? If so. I would offer you to work together. So that the patcher and the client will create a save grf. (Save for modifikations) I also want to make the patcher checking for Bots and WPE tools. Edited April 3, 2016 by Vincentore Quote Link to comment Share on other sites More sharing options...

If it doesn't match, it will be redownloaded from patch server. Quote Link to comment Share on other sites More sharing options...

(Save for modifikations) I also want to make the patcher checking for Bots and WPE tools. yeah I do, the common languages I use is C#/VB.net and C++. I can easily read and understand the codes in rAthena's server-side. Another thing is about WPE hack. On this topic rAthena now is WPE Free https://rathena.org/board/topic/101092-packet-obfuscation-support/ how sure is that? or this is just a some layer of protection? for bots Prevention you can only create packet different keys for all customers who use the guard Yeah that will be great! That would be easy after I tried this project soon! Also file verification is important, so we have an ability to list all files with its correct hash. If it doesn't match, it will be redownloaded from patch server. That is great that will be on compiled grf side. Well I have a question, what kind of hack that they do in grf file? SKILL DELAYS?

On this topic rAthena now is WPE Free https://rathena.org/board/topic/101092-packet-obfuscation-support/ how sure is that? I dont know if every packet is sended with the keys. If so WPE should not be able to abuse an client. But I would also check for WPE tools. There is a git project named "Lesser GRF" which is replacing the CPS.DLL. It is written in C++. I dont know the GIT Link right now but there is one. I could send you a build but it is 4 Months old. (I dont know if there are recent commits) Quote Link to comment Share on other sites More sharing options...

Any related development will be a great help. It would be a great help if someone can post some of the compiled application e.g. Grf Encryption, Packet Analyzer, etc. So that I can analyzed the algorithm for my plan on making this GameGuard. it doesn't matter if its not an open source. I just need the flow/process of that kind of application. I will try to write the code by myself. Edited April 6, 2016 by Vidz Quote Link to comment Share on other sites More sharing options...

I already made some of my function in the client side and now I am making some functions in the server side. If you are internested to be as one of my team in this development please send me a message here in rAthena. I will send my personal email address to you.
