Here is the complete package translated into English, ready to be used on your website.

I have separated it into two parts:

🕵️‍♂️ Mission: Operation INIT

Agent, welcome to HTD Academy.

Our intelligence team has intercepted access credentials for a remote server used by an unknown group. We suspect this machine, codenamed “INIT”, is running a Parrot OS distribution modified to hide sensitive information.

Your mission, should you choose to accept it, is to establish a secure SSH connection, infiltrate the system, and perform a full reconnaissance scan. We need you to extract crucial details about the infrastructure, the user environment, and the network architecture.

Warning: Not everything is as it seems. The system might be masking its real Kernel version to confuse intruders. Trust only the data you extract yourself.

Good luck, Initiate.

📂 Access Data (Briefing)

  • Target: Local Server (Docker Container)
  • Protocol: SSH
  • Port: 22
  • User: dome-scout
  • Password: Oper@tion_Sh3ll!

🧠 Key Concepts (Learning Outcomes)

By completing this “Capture The Flag” (CTF) challenge, you will practice essential Linux administration and auditing fundamentals:

  1. Secure Remote Access: Using the SSH protocol on non-standard ports.
  2. System Enumeration: Identifying processor architecture and Kernel versions (crucial for vulnerability scanning).
  3. Environment Variables: Understanding how Linux stores user configurations, such as the default shell ($SHELL) and home directories ($HOME).
  4. Linux File Hierarchy: Navigating critical directories like /var/mail and /home.
  5. Network Analysis: Identifying network interfaces and reading technical configurations like MTU (Maximum Transmission Unit).

Download the machine from Github and start it

git clone https://github.com/suricatoti/init.git

cd init

docker build -t htd/init:v1 .

docker run -d -p 2223:22 --name htd-init-lab --mount type=volume,source=htd_ssh_keys,target=/etc/ssh/ localhost/htd/init:v1

ssh dome-scout@localhost -p 2223
