GoKawiilDeveloper reverse engineers Hitster board game's Android app, bypasses paywall
A blogger reverse engineered the Android app for the music guessing board game Hitster, decompiling its APK with jadx to inspect its code. They found a JSON file containing an encrypted card-to-song database and located the AES decryption routine directly in the app's source, allowing them to decode the mapping between card IDs and Spotify tracks without needing a paid Spotify or Apple Music subscription.
GoKawiil's interpretation of the reporting above, not reported fact.
The case illustrates how weak app-level encryption can be undone once source code is exposed through decompilation, since hardcoding a decryption key or algorithm inside the client offers little real protection. It also highlights a recurring tension for physical-digital hybrid games that gate content behind paid streaming subscriptions, which may push curious users toward bypassing those paywalls. The findings could prompt Hitster's developers to reconsider how they secure their card database going forward.
- A hobbyist decompiled the Hitster Android APK using jadx to inspect its internal logic.
- The app's card-to-song database was Base64-encoded and AES-encrypted, but the decryption process was found directly in the app's own code.
- The exercise shows how easily client-side encryption can be bypassed when secrets are embedded in distributed app code.
