Metasploit tip: Use help to learn more about any command Now, we can fire up Metasploit by typing msfconsole in the terminal. First, start the PostgreSQL database with the following command.
The first method we will try out today involves one of Metasploit's auxiliary scanners. It would be a waste of time if this was closed or not running at all. Nmap done: 1 IP address (1 host up) scanned in 13.33 secondsĪbove, we can see that port 22 is open and the SSH service is running on it.
MAC Address: 08:00:27:77:62:6C (Oracle VirtualBox virtual NIC) Instead of scanning all the default ports, we can specify a single port number with the -p flag. We can perform a simple Nmap scan to see if it is open or not. Virtually every large enterprise implements SSH in one way or another, making it a valuable technology to become acquainted with.īefore we begin any brute-force attacks, we need to determine the state of the port that SSH is running on. Uses for SSH include providing a means for remote logins and command execution, file transfer, mobile development, and connectivity troubleshooting in cloud-based applications. Recommended Reading Material: SSH, The Secure Shell: The Definitive Guide SSH can use both password and private key authentication, the latter of which is considered more secure. That is, the client initiates a connection to the server, and communication is established after authentication takes place. The SSH cryptographic network protocol operates on a client-server model. This was developed as an alternative to Telnet, which sends information in plaintext, which is clearly a problem, especially when passwords are involved. SSH, which stands for Secure Shell, is a network protocol that allows for encrypted communication over an insecure network. As for the target, we will be practicing on Metasploitable 2, a purposely vulnerable test environment for pentesting and security research. While not the only ways to do so, we'll be exploring tools such as Metasploit, Hydra, and the Nmap Scripting Engine in Nmap to accomplish this task, all of which are included in Kali Linux. There are a few methods of performing an SSH brute-force attack that will ultimately lead to the discovery of valid login credentials. One of the most reliable ways to gain SSH access to servers is by brute-forcing credentials.
SSH is one of the most common protocols in use in modern IT infrastructures, and because of this, it can be a valuable attack vector for hackers.
