I want to know how to use frida-il2cpp-bridge

[daeinlee]

Hello.
Thanks for making such a great tool.
First of all, I would appreciate it if you note that the text may be a bit odd since I used a translator to write the question.

I often use Frida for work, and I have mainly used it as a JavaScript file using frida tools.
Global-metadata.dat is looking for a decryption method, and I found the frida-il2cpp-bridge that does not need global-metadata.dat and is looking at how to use it, but I do not know how to use it due to my lack of knowledge.
So, I prepared a few questions, and if there are answers, it will be easier to understand.

1. Does frida-il2cpp-bridge use node frida (npm install frida)?

2. Can I know how to use it? I want to know how to run the code, not what it is. (ex: frida -U -l hook.js -f com.android.chrome --no-pause )

3. When the code runs, is it correct to send a log with metadata information when the package's unity-related code is executed?

Thank you very much for your reply.

Hi!

I have mainly used it as a JavaScript file using frida tools.

This is the same; but I suggest you to use TypeScript, it's very helpful and I only support TS users.

Shortly:

1. Not necessarily, I use frida or frida-inject directly - however you must generate a single .js file using frida-compile or whatever bundler you prefer;
2. Please read carefully here and here - outdated, but helpful;
3. I'm not sure what you mean - however the answer is you can pretty much do anything you want.

So, you have to:

1. Understand what is a TS project and how you can create one;
2. Understand that frida-compile transforms multiple TS file into a single JS one
3. Call frida with the generated file (you already know this step)

PS: I'll move this issue to the "discussions" section
