Just a simple or little writeup !!!!!

Decompilation long with a lot of folders, files, and others !!!!!!

Just use "unzip stress.apk -d stress"

As in all CTF with apk, the first thing to do is lookin at the folder /assets/ !!!!

Just see in folders /stress/assets/bin/Data with file level0 !!!!

Just "strings level0 | grep flag{"

BINGO "flag{1_kn0w_ARCore}"

To sha256 ===> a621b0c77657bb1f80a843dba19521a0362905aac51a0b27e49b3fd2a1a13c61

This is the flag for 453 points: "a621b0c77657bb1f80a843dba19521a0362905aac51a0b27e49b3fd2a1a13c61"

Thanks and i'm sorry for the little writeup but no need for more for a little writeup !!!!!
