Okay I was able to get SSH access as the one starting with b by feeding stuff to my good friend John and I found two ways to get root. One tedious through the “high thing” foo and one super easy way to bypass this whole ordeal due to the way a certain binary is programmed. (First used the easy method and then the tedious one hoping to get root flag this way…)
Don’t know if the easy path (lol) is intended by the machine author…
But maybe somebody can point me wtf "RC" in this newfangled and insecure hipster industry stands for? Google only gives me crappy results when I search for that combined with E*****m. Does it somehow relate to the first block?
