Any clue ? Basic Knowledge required? I mean, I find what i want, but, not sure what to do with it

I found flag, but it is not accepted and it is not 100% compatible with flag format ( contains some additional spaces). I tried to modify it a little bit to match flag format but no success.

Nice challenge, thanks InFeRnOo !

nice challenge! message if you need help

I have the same situation as keeper772. Don’t know what I must do with it.


I will share the tricks:

  1. You need to understand how passwords are stored in Android (device_policies.xml).
  2. If you use Hashcat, remember to change the mask (you need to).
  3. For the app that contains the flag, you can find a tool on GitHub :wink:

PM me :wink:
