Help! Encrypted libil2cpp.so and global-metadata.dat

Rookie
Hello, I'm trying to gather information about a Unity3D game, but I’ve run into several challenges.

In the APK version of the game, there are libil2cpp.so and global-metadata.dat files, but they are encrypted, so I can't get any results with Il2CppDumper. Once the game is installed, these files hide themselves, making it even harder to access them.

I've tried multiple decryption methods, but the result remains the same. I also attempted to analyze the game by redirecting its network data to myself, but all the traffic is in HEX format and encrypted. I tried various decryption techniques on this data as well, but I couldn't succeed. Some information was partially retrieved, but not in the way I needed—names appeared correct but scrambled, and I couldn't extract any deeper details.

I tried multiple memory dump techniques using Frida, but all attempts failed. I also extracted libil2cpp.so and global-metadata.dat from memory using PMT Dumper, yet they were still encrypted, and I wasn’t able to break the encryption.

The game is constantly exchanging data between the client and server, and I’ve come across a few people who managed to decrypt it, but none of them shared any hints or guidance.

I've been trying for over a month, testing every possible method I could think of, but I'm stuck. It’s exhausting, and that’s why I’m looking for help. I’ve posted in multiple places, but most people just ignored my request.

I’m not asking anyone to crack this for me—I’ll keep working on it myself. However, I would really appreciate any guidance on what I should try next.

It's an online game, and I can share its name if it's allowed. Also, to clarify—I’m not looking for cheats or hacks. My only goal is to collect and organize publicly available in-game data more efficiently.

Any help or suggestions would be greatly appreciated. Thank you in advance!

To be honest, I'm new to this field and can't say that I'm very good at it. However, I've been working with Python for many years, but this is outside my expertise, and I'm trying to learn. For the past month, I've even tried several AI tools to guide me, but I still feel stuck.


I saw a few posts about this game on the forum, I think it is not forbidden to share the game name. Game Whiteout Survival
Again, I want to add as a note that I don't want to change any data or cheat. I want to monitor game data, it can be thought of as an API
