About the Challenge

We were given a jpg file and we need to find the flag inside the image

How to Solve?

First, run binwalk or you can use CyberChef and then choose Extract File operator. You will see a xz file

Open the xz file and you will find 2 images called key.png and flag.jpg. Input the key.png file into AperiSolve or you can zsteg tool to extract the key

You got the password! And right now you can use steghide or AperiSolve again but don't forget to input uR_aLmOsT_tHeRe in the form input

Download the result and voilà!
