I've recently joined and successfully rooted my first box within a few days (0bscura) - Yeppee!
On my next box (Traverxec) I'm a bit stuck right now but no worries. However by accident I came across multiple files on Traverxec that I suppose where left by other user. Essentially I could complete the box now with the help of those files. But I'm here to learn! I'll take my time to solve the complete path myself, I've got the hint from the forums that after the initial RCE it's about exploiting j*****.d*** - and after that I know already what's coming through the mentioned files.
Still I wanted to know if it's against the rules to do so, to use what others left behind? I ask because I made an online course about the topic and the tutor essentially stated that it's "best practice" to look for & utilize holes that potential other "hackers" left for you.
Like to hear your's oppinion.
