Description:

What the naked eye sees is not always true. Maybe there is something hidden behind it. Don't try to see metadata of given file.

Solution:

We opened the provided challenge txt file and noticed that it appeared empty.

However, when we selected all the text, we discovered that there was hidden, invisible text. We copied the invisible text.

The invisible text might contain hidden zero-width characters. To decrypt it, we used the following website: https://www.irongeek.com/i.php?page=security/unicode-steganography-homoglyph-encoder

After decoding the text, we finally found the flag.

flag: IHC_CTF{S7EG_C7F}
