First look
Finding the way in
At the starting, We extracted two images from the zipfile, an anime sunset and a Warli painting.
We identified a Bird on a Wire cipher in the first image and a Dancing Men cipher in the second.
Using the respective websites, we decoded them into ABCDJKLM and EHTVM.
Following the hint passphrase given, we combined them as ABCDJKLM+EHTVM, including the plus sign.
We used this passphrase with Steghide to extract the hidden message from both images
