Description:
There has a brief information about OSINT. But there has more hidden information.
Solution :
We found a text from CTF604.txt
Here is the encrypted text :
Open-Source Intelligence (OSINT) is defined as intelligence produced by collecting, evaluating and analyzing publicly available information with the purpose of answering a specific intelligence question.
when I pest text in CyberChef I see this
I guessed there is some hidden characters,as I know I tried my Hidden Unicode Characters or 0 widths Characters Decoder
but that doesn't support the characters
after searching for several minutes, I found a decoder website
https://www.irongeek.com/i.php?page=security/unicode-steganography-homoglyph-encoder
and load values here then decode it and get The Flag.
