After reading carefully the description and the hints (1), I started looking for any files hiding in the image.
I found some files so I extracted them.

We now have a ZIP file and a TXT file. The ZIP file isn't important because it contains a copy of the TXT file.

The TXT file contains a list of Pokémons.

I had no idea of what to do... Then I read again the first hint (1) and I decided to search on the Internet "cloak factory forensics" and I clicked on the first [result](https://www.hackingarticles.in/cloakify-factory-a-data-exfiltration-tool-uses-text-based-steganography/), which talks about a tool called [CloakifyFactory](https://github.com/TryCatchHCF/Cloakify). After reading the article I thought that probably it's the same program used on the list that I found.

Here I used the option 6, which is the pokemonGo cipher.

And then I got the flag:
