Spiir CTF Puzzle

So you feel, you are a clever developer that knows every bits and bytes of tech? Do things like reverse engineering, cryptography and obfuscation peek your natural curiosity and imagination? How about taking on an exciting challenge that will test your skills against likeminded? Your curiosity will surely be triggered and you will not rest before the challenge has been solved - all the way. Did you bail out? Or you still here? Ahh, still here 😄 So curiosity took over, eh? Lets start then… The challenge is basically to capture 20 flags from this Android app. You just need to download the app and then get going. We expect you to easily figure out at least 7 flags, getting past 15 flags will be reserved for less than 10% of all participants. Get all 20 flags and you’re one of a few. Download the app and the game is on! 💪
