An Android based CTF to improve and hone your dynamic analysis skills!

Rules:

1. No using Frida for dynamic modification / hooking.
2. No manual invoking of activities via drozer / AM.

Goal:

Your goal is to pop the FinalActivity activity on your device, keeping rule number 2 in mind.

Note to player:

This isn't an Android CTF where you can just decompile the APK, de-obfuscate some encrypted keys from strings.xml, read some static values from a random class etc. In order to solve this CTF, you will need to think very creatively, as most of the stages need to be solved via pure dynamic analysis. I have neither hidden any "gotchas" in the code, nor have I obfuscated the code.

Good luck and have fun!
