Hey everyone, in this write-up we will be solving an HTB challenge Don’t Overreact.
Link to the challenge: https://app.hackthebox.com/challenges/255
Let’s Start!!!!!!
First download and extract the given file.
Next I opened the apk with jadx-gui.
I checked the AndroidManifest.xml file and found that we need at least API version 21 to run this app and the target API version is 29 i.e., Android 10. So, I installed the app on Android 10 emulator.
Now let’s open the app and have look at it.
It’s just a simple page with HackTheBox Logo.
Let’s take a look at the source code.
On taking a look at the MainApplication class file, we can see that its a React Native application.
React Native application usually stores all the javascript as a single bundle file under the assets directory. So let’s take a look at it.
In the index.android.bundle, file if you scroll down to the end, you can find a base64 encoded version of the flag. Copy that and decode it using CyberChef.
We have successfully obtained the flag……..
Thank You………
