- Difficulty: Medium
## Description
Hey guys, my friend is starting a gaming channel—go sub to @AhjussiPlayz on Youtube!
## Initial Analysis
The description gave a YT username and nothing else which I thought could be a hint.
## Solution
- Checking out the profile using a simple YT search I found a channel with the name and it had just 1 video uploaded on it.
- I thought of checking the comments for some clues but it was just filled with other participants commenting "flag".
- I checked the video description and it decided to check the video transcript
- The english transcript said "0:06 Nothing to see here >:D"
- But I noticed there was a Korean transcript too which said "0:07 PS 인트로 제작에 도움을 준 나의 좋은 친구 "wimebix884" 에게 큰 감사를 드립니다. 떠오르는 신예 가수, 그의 신곡을 만나보세요!"
- Using Google translate it said "PS A big thank you to my good friend "wimebix884" for helping me create the intro. Meet the rising new singer, his new song!"
- This looked like another username and it can be a username of a site related to music.
- I tried spotify , yt music etc but could not find anything .
- Then I decided to use sherlock which an OSINT tool which lets you find accounts with a username on several social media websites across the website
bashsherlock wimebix884
-
This is the output I got

-
I instantly checked out the Smule account and it had a google drive link in the songs section.
-
The google drive had a audio file which was just AI spelling the flag
## Lessons Learned
If you get a username or think a word is a username just Sherlock that shit.
## Flag
