Yes, this is a Demonstrate Your Skills Lab. I extracted the SSH key, but I am not able to find the IP address of the Postgres server. OrchidDB AI Chatbot did not tell me, even in maintenance mode, I ran a lot of Nmap -p 22, but no server is accepting the key. e.g., 10.102.105.91 Permission denied (publickey,password,keyboard-interactive)21Views0likes1CommentKerberos: Active Directory Certificate Services lab - getting KRB-ERROR (16): KDC_ERR_PADATA_TYPE_NOSUPP

Can someone point me to the right track? On this one, I found the hidden directory, used an X-Forwarded-For: to see into that directory where scanning for files showed a lot of 404s, with just a few 403 response codes. I've tried everything I can think of with variations on X-Original-URL:, X-Rewrite-URL:, and X-Forwarded-Uri:, but none of them get me able to see into any of the files/directories. I've even tried a few variations instead of X-Forwarded-For:, such as X-Client-IP: and a few others. I feel like I must be missing something. I didn't find any actual .php files in the hidden directory but the question seems to indicate that there are some in there. I found what I think are other directories within that first hidden directory.Solved44Views0likes2CommentsNetcat: Advanced Features last question (9)

Hi all, Just wanted some advice on this as I am stuck. I managed to get into the intranet using SQL injection/union and extract all the usernames and passwords. I am not sure if I am on the wrong path or doing things in the wrong order for the next part. The FTP server seems to only be active on RDP. The DC has no samba vulnerabilities. So... I assume I try to use the credentials from the intranet to RDP to the DC/FTP (then after this elevate access using other techniques) but so far that has failed for the Armsdon users I have tried their users/passwords (from the intranet). Any tips welcome!91Views0likes2CommentsTrick or Treat on Specter Street: Morphy's Mansion Challenge
I understand that the move_logger is the vulnerable program, and tried a few methods to exploit it. However, where is the token.txt? Anyone managed to find it? "Whatever means necessary" is quite broad. Any hints from anyone?Solved177Views0likes1CommentTrick or Treat on Specter Street: Serpent Sanctum
So for this challenge we have got hint: (serpent-statue) $ hint Maybe the fang can be in two places at once... Tried to copy both fang.key and fang2.key to statue folder but it did not allow me. The error message: The statue's eyes flare red with anger. This is merely a copy; a false fang with no power. The worthless copy crumbles to dust in your hands. What other methods can we try here? Anyone solved it already?Solved135Views0likes5CommentsCVE-2022-30190 (Follina) ms-msdt Scheme Abuse – Offensive Question 11
Hey guys, wondering if when trying to upload the payload for "Question 11: In a browser, visit http://<TARGET_IP>:8080, upload the payload.docx file, then press Submit and Execute" if this error is supposed to be generated. After choosing the file after clicking browse sometimes this work. After executing nothing seems to happen though. even after 30 seconds of waiting.Solved70Views0likes1Comment
