So download the file.

Unzip it and notice the challenge name is Snow so use stegsnow.

Once extracted you get a file called chall.txt which presumably you use stegsnow on.

However theres hidden directories. If you go down it you find .flag.txt which is a fake flag but if you go further you find .secret.txt which is the password.

So run stegsnow -C -p "welc0me_to_zh3r0_ctf" chall.txt and you get the flag.

Flag: zh3r0{i5_it_sn0w1ng?}
