NahamCon 2024

Install the APK with ADB

				
					adb install -r buggyjumper.apk
				
			

Let’s decompile it with apktool

				
					apktool d buggyjumper.apk
				
			

The app has been developed in Godot Engine. So, we can use this tool
https://github.com/GDRETools/gdsdecomp

When you have the tool installed, just launch it.
We can see in the directory that apktool has drop to us this directory
/buggyjumper/assets/scripts
Inside:

				
					.
├── flag.gdc
├── flag.gd.remap
├── MainScene.gdc
├── MainScene.gd.remap
├── shop.gdc
└── shop.gd.remap
				
			

Let’s check the file flag.gdc with the gdre_tools.

Then, now just strings flag.gd and we get the flag.

Flag: flag{c2d5a0c9cae9857a3cfa662cd2869835}

I hope you found it useful (:
