Lot of comments here seem to think that there’s no novelty. I disagree. As a new ML engineer I am not very familiar with any reverse engineering techniques and this is a good starting point. Something about ML yet it’s simple enough to follow, and my 17yr old cousin who is ambitious to start cyber security would love this article. Maybe its too advanced for him!

Thanks a lot :)

My general writing style is directed mainly towards my non-technical colleagues, which I wish to inspire to learn about computers.

This is no novelty, by far, it is a pretty standard use-case of Frida. But I think many people, even software developers, don't grasp the concept of "what runs on your device is yours, you just dont have it yet".

Especially in mobile apps, many devs get sloppy on their mobile APIs because you can't just open the developer tools.

I'm a mobile developer and I'm new to using Frida and other such tools. Do you have any tips or reading material on how to use things like Frida?

I think you are starting off from the perfect direction, being a forward-engineer first, and then a reverse-engineer.

The community around Frida is a a) a bit small and b) a bit unorganized/shadowy. You cannot find that many resources, atleast I have not found them.

I would suggest you to use Objection, explore an app, enumerate the classes with android hooking list classes or android hooking search classes, then dynamically watch and unwatch them. That is the quickest way to start, when you start developing your own scripts you can always check out code at https://codeshare.frida.re/.

For everything else join the Frida Telegram chat, most knowledge sits there, I am also there feel free to reach out to @altayakkus

Oh and btw, I would start with Android, even though iOS is fun too, and I would really really suggest getting a rooted phone/emulator. For the Android Studio Emulator you can use rootAVD (GitHub), just install Magisk Frida. Installing the Frida gadget into APKs is a mess which you wont miss when you go root
