In this write-up I will be explaining how I solved the challenge growingup of the CyberSoc CTF | Cyber Detective. The challenge windows displays the following information: Once again, all we have is James Markson's Twitter profile. The challenge is asking us the place where James spent his childhood. In other words, the place where was raised, not necessarily where he was born. This reminded me of a not-so-common profile bio that I saw the first time I visited James' profile.

I decided to browse his tweets to see if there was any clue of his political bias. Quickly, I found a tweet of Feb 10, 2020 which he retweed and made a comment about a Barack Obama's tweet.

Some people might immediately know which party is this. However, let's assume we have to find out that too. With a quick Google search looking for Obama's party it is possible to find that out and get the flag.
