Help! About Modding and Security

[sadep12]

Hello,

I need help about something. I started to improve myself on mobile game hacking, I managed to do the modding for various mobile games successfully.

Recently an alfa testing started for a mobile game that will be released in my country. I did some trials on this game and managed to enable some features with Assembly-CSharp.dll.

With the new version they took some precautions. I couldn't figure out what are those for now, my request from you is helping me out with this process.

1-) How could i learn what method is being used for this game's protection?
2-) If this game was updated with MD5 control system, how could i bypass that?

I really need your help with this learning phase. The game i mentioned is still in Alpha level so you can only play it with an invatiation. For that, you can download smali and managed files from the link below. Also, if you can figure out what system is being used to protect the game without logging into the game, I can share game file too.

Hello G-Bo bro,

Here is APK file: https://app.box.com/file/199855268276

After the updating, I can't login anymore when I edited Assembly-CSharp.dll. I guess they changed their security system (MD5 or like this). Game server now will check the MD5 info or like this, if it's not the official publish data, I can not login.

Before I take a look, is you device rooted and lucky patcher patched? Cause it sounds like signature check inside the game. So you can test easy if the game starts as unsigned apk

Yes, I tested rooted with patched by lp. I already checked unsigned but it didn't work.

When I make a small change on the Assembly-CSharp.dll then I can not login. I tested with sign and unsigned file.
