Rooted. Thanks @drywaterv2 for your encouragement to watch carefully the service.
To be honest, when I was somewhere in the middle of acquiring the user flag, I was quite frustrated. The reason is that I hate CTF-like boxes, and to be honest the whole user part was not really realistic. Plus, I hate brute-forcing stuff. Anyways, what I like a lot is the root part, that even though it’s easy for most people, is something different from what you usually see in this kind of boxes … and it was also pretty realistic as far as I am concerned. For this reason, I rep up this box. If you have any question, feel free to PM me, and I will try my best to answer you back ASAP.
