Hello guys, I have completed this challenge. In my personal opinion, this challenge was of medium difficulty... Let me tell you how it was done.
At first I used "file , strings and exiftool" Commands , but I didn't get a result, so I thought about the name of the attached file in the challenge and searched for it, and I knew that this file is a USB Rubbery Ducky
After searching, I found this useful site to decrypt the file : After decrypting this file, we got a file with the name : "duckeycode.txt" , And it contains this command :

Now, we must decode these output until we Capture The Flag 💪🏼⛳️
haha this is very nice idea to digital forensics challenges , I really enjoyed solving this challenge ;)
