Secure Shell

The Secure Shell Protocol is a network protocol for operating network services securely over an network. Its most notable applications are remote login and command-line execution.

SSH usually uses port 22, however, for this task, the ssh server is running in a mysterious unknown port.

to connect to a specific port using ssh, you can use the command ssh <ip_address> -p <port>

Challenge Instructions:

1. Scan the Ports: Use the Nmap tool to scan the target machine and identify the open ports. Your goal is to find the port where the SSH service is running.
2. Connect to SSH: Once you've identified the SSH port, establish a connection to it using an SSH client. Once connected, you'll be prompted to enter credentials.
3. Retrieve the Flag: Upon successful authentication, you'll gain access to the target system. Your final task is to locate and retrieve the flag file, which contains the secret passphrase you need to complete the challenge.

The Challenge:

Your mission is to discover the SSH service running on the target machine, connect to it, and retrieve the flag.
