Rooted. Hints
Initial: it honestly couldn’t be easier than google
user1: Based on the talk here some people had to work for this, I don’t know why, my googling for the initial foothold pretty much gave me what I needed, though I had to upgrade my access a bit to let me use it
user2: I myself make the mistake of thinking that in CTFs everything has to be some kind of technical exploit, but even on Hackthebox it still holds true that PEOPLE ARE LAZY, so try really dumb things
root: this one was not obvious to me at all, but through rigorous googling you’ll find something that you can use. That said, you really don’t have to look far. But you do have to google, and don’t pass up things that look benign just because you don’t really know what it is
