Stego challenge that start with a text file oh look! binary? we can get an image from that! I used an online tool to draw the binary-image the size of the image is 50x50 (the hints say it too) and you get a QR code!

you can use zbarimg from Zbar tools (what I did)

or any online qr decoder like this one The flag is revealed when you decode the QR image!
