For this example, we’ll brute force attack the FTP service of a virtualized machine that’s been made exploitable using ‘Metasploit’, which has the ip address ‘192.168.1.101’:.To open go go to ‘Applications’ > ‘Password Attacks’ > ‘Online Attacks’ > ‘hydra’.For example, cisco auth, cisco enable, cvs, ftp, http and https-form get, http and https-form post, proxy, imap and irc, etc, etc. Hydra is an application for cracking ‘login’ and supports many protocols, or vectors, to attack.

Most methods for password cracking require a powerful computer to produce many candidate passwords, or rainbow tables, against which each password is checked. Bit strength is the measure of a password’s entropy as well as the details of how the password is actually stored. The time to crack a password is directly related to its Bit strength. Password cracking can not only take quite some time, it’s also computationally expensive to accomplish at scale. A common approach is to repeatedly guess the password and check them against an available cryptographic hash of the password – otherwise known as ‘brute-force attack’. Password cracking is the process of recovering passwords from data that’s been stored or transmitted electronically by a computer system in a scrambled form. Or, more commonly, some users are more likely to reuse the same password for everything.

Passwords that are difficult to remember can also reduce the security of a system transversely as most users might need to write down or electronically store the password using an insecure method. Why? To stop people or bad actors from gaining access to your top secret stuff, whatever it may be. It’s massively important that passwords are difficult to remember or guess.
