You can get `cat.png` from the Problem.
use command `binwalk` to get information from the header, then you will find out some "Zlib compressed data" inside.
use command `foremost` to recover the image , you will get other two images and also have zlib inside, respectively.
use the command below to see the difference between two images in pixels.
compare 00000000.png 00000725.png -compose src diff.png
After scanning the QR code, you can get the final image, using any text editor or command `strings` to find the flag inside.
