1. Ignoring UDP Ports: The box hides a TFTP (Trivial File Transfer Protocol) service on UDP port 69. Downloading a file called backup.cfg from TFTP reveals SSH keys.
2. Assuming the Name is Literal: Do not let the word "fail" stop you. When you find a potential exploit, test it 50 times. The box’s error messages are designed to lie to you.
3. Not Checking for Virtual Hosts: As mentioned earlier, this is the number one "aha" moment. Use gobuster vhost -u hackfail.htb -w /usr/share/wordlists/seclists/Discovery/DNS/subdomains-top1million-5000.txt.
