Description: $root of cybsec is so popular that you can find him easily everywhere. And it's really tough for him to hide his flag.
If we go to Cybsec's team page, we'll see $root first on the list. Clicking on his name will take us to his website.
Looking around a little bit, we find the about page of his website.
And there it is! We have the flag. pCTF{1_4m_r00t}
