Emoji  - Forensics Challenge 

For this challenge a JavaScript file is provided. Once opened, tons of emojis appear.

It seems incomprehensible but as the challenge description explains, it's an encoded file. I then did some research and asked Google.

I finally found that the encoding used was aaencode, a technique created by the Japanese Yosuke Hasegawa which allows to create emoji variable and insert emoji.

Once decrypted I got the Flag.
