Oh man this one is driving me nuts!.. question 3 on the skills assessment “What is the API key in the hidden admin directory that you have discovered on the target system?”
that I have not seen anyone else mention that seems to be at the root of the issue… any ideas so I can move on with my life and hopefully one day see my family again!
Since it’s a local domain (.htb) don’t spend time on the DNS enumeration. You need gobuster for vhosts or subdomain. Once the tool discovers the subdomain, you need to add it to /etc/hosts so that the IP can resolve to the newly added domain. You repeat this step until you complete all challenges.
