67 TopicsBrute Force task in an 15 min lab taking over 30 hours to complete
Hello everyone, I am doing an Immersive Labs about hacking, and there is a lab where I can learn how to crack codes with Hydra using SSH, HTTP, and FTP. The problem is that for the FTP part, I am supposed to brute-force a password (a 4-character password composed of lowercase letters and numbers). I am using the correct command, but the brute force is extremely slow, doing roughly 1 attempt every 3.5 seconds, which brings the total cracking time to over 30 hours. I waited 2 hours already, which is far too long, especially since the lab has to be extended every 10–15 minutes. However, now it has become personal, and I really want to get this password. Can anyone help? I am using the following command: hydra -l jimmy -x 4:4:1a -f -t 64 ftp://(ip address) i have tried -t, 4, 8 and 16, doesn't change anything I also tried creating 4 lists containing all possible passwords and running them in parallel with -P instead of using -x, but I always got too many attempts.

Hello, I completed all the questions but I'm stuck with N.6: "What is the token in the service account's home directory on the database host?" I got the ssh key. I got the user. I got the host. chmod 600 key DONE Got the ssh key in 2 ways: by the chatbot and with: CREATE TABLE files(filename text); COPY files FROM '/var/lib/postgresql/.ssh/id_rsa'; SELECT * FROM files But I'm always getting this error when I try to ssh: Load key "key": error in libcrypto I tried to fix the format of the key without success. May be the key on the exercise corrupted? This is the key that I got: -----BEGIN OPENSSH PRIVATE KEY----- b3BlbnNzaC1rZXktdjEAAAAABG5vbmUAAAAEbm9uZQAAAAAAAAABAAAAMwAAAAtzc2gtZW QyNTUxOQAAACDEKK7X95Yx0arxuFpnbCOazXs94GtBxZEmZEwOfjkfWQAAAKBu/iwgbv4s IAAAAAtzc2gtZWQyNTUxOQAAACDEKK7X95Yx0arxuFpnbCOazXs94GtBxZEmZEwOfjkfWQ AAAEBmm/CMDy59G26K1pC9J2l+PKqcTL89F4kmh/5Idt9hd8Qortf3ljHRqvG4WmdsI5rN nez3ga0HFkSZkTA5+OR9ZAAAAFm9yY2hpZC1zdmNAcG9zdGdyZXMtZGIBAgMEBQYH -----END OPENSSH PRIVATE KEY----- ThanksSolved41Views0likes1CommentAI Red Teaming: Lateral Movement and Privilege Escalation – Demonstrate Your Skills
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)36Views0likes1CommentKerberos: 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.Solved56Views0likes2CommentsNetcat: 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!95Views0likes2CommentsTrick 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?Solved189Views0likes1CommentTrick 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?Solved149Views0likes5Comments
