For this challenge, there TWO ways to solve this challenge. We will be explaining them both! 🎉

We received an APK file and I got really excited, because I love Android programming! The first thing our team did was to extract the.apk file via apktool.

apktool

Solution 1

Do you know where the image assets are stored? I've made a nice drawing for you.

The challenge description gives us a hint where the flag should be located. The TWO keywords here are image assets and drawing.

Having experience Android programming, the flag are probably located in drawable (res -> drawable-hdpi) folder. It is the folder where most images/graphics are stored! From there, we managed to get the flag!! ☺️

Flag: grey{th1s_dr4w4bl3_bu7_e4s13r_t0_7yp3}

Solution 2

This solution is similar Firmware's Solution 2. We will be using command lines to recursively search for the flag!

find "$(cd ..; pwd)" -iname "*flag*"

flag!!

Flag: grey{th1s_dr4w4bl3_bu7_e4s13r_t0_7yp3}

Gotta eat Omega 3 to boost my memory 😭
