Hello, today I am going to show you how to crack passwords using a Kali Linux tools.Remember, almost all my tutorials are based on Kali Linux so be sure to install it.I am going to show you these :1. Cracking Linux User Password2.Cracking Password Protected ZIP/RAR Files3.Decrypting MD5 Hash4.Using Wordlists To Crack PasswordsLets begin.
I don't really recommend this one, but there are some peoples out there using this to crack...I will crack a hash that is inside a text file.I have a wordlist here, and I named it password.txt.To use the wordlist and crack the file, do :
No, not if you have a targeted list. I tested this on a password protected rar file i had someone create. I extracted the hash & ran john againt it. It ran for a solid 36 hours attempting a bruteforce in iteration mode. John never found it. Using a custom list I cracked the hash in 36 minutes.
Password cracking is a mechanism that is used in most of the parts of hacking. Exploitation uses it to exploit the applications by cracking their administrator or other account passwords, Information Gathering uses it when we have to get the social media or other accounts of the C.E.O. or other employees of the target organization, Wifi Hacking uses it when we have to crack the hash from the captured wifi password hash file, etc.
So to be a good Ethical hacker one must be aware of password cracking techniques. Though it is easy to crack passwords by just using guessing techniques, it is very time consuming and less efficient so in order to automate the task, we have a lot of tools. When it comes to tools Kali Linux is the Operating System that stands first, So here we have a list of tools in Kali Linux that may be used for Password Cracking.
In order to hack a password, we have to try a lot of passwords to get the right one. When an attacker uses thousands or millions of words or character combinations to crack a password there is no surety that any one of those millions of combinations will work or not. This collection of a different combination of characters is called a wordlist. And in order to crack a password or a hash, we need to have a good wordlist which could break the password. So to do so we have a tool in Kali Linux called crunch.
Burp Suite is one of the most popular web application security testing software. It is used as a proxy, so all the requests from the browser with the proxy pass through it. And as the request passes through the burp suite, it allows us to make changes to those requests as per our need which is good for testing vulnerabilities like XSS or SQLi or even any vulnerability related to the web. Kali Linux comes with burp suite community edition which is free but there is a paid edition of this tool known as burp suite professional which has a lot many functions as compared to burp suite community edition. It comes with an intruder tool that automates the process of password cracking through wordlists.
John the Ripper is a great tool for cracking passwords using some famous brute for attacks like dictionary attack or custom wordlist attack etc. It is even used to crack the hashes or passwords for the zipped or compressed files and even locked files as well.

In Mask attack, we know about humans and how they design passwords. The above password matches a simple but common pattern. A name and year appended to it. We can also configure the attack to try the upper-case letters only in the first position. It is very uncommon to see an upper-case letter only in the second or the third position. To make it short, with Mask attack we can reduce the keyspace to 52*26*26*26*26*10*10*10*10 (237.627.520.000) combinations. With the same cracking rate of 100M/s, this requires just 40 minutes to complete.
Today I am going to share how to crack zip password by using Fcrackzip on both operating system windows as well as Kali Linux. You can crack zip password by running simple commands. some commands will give your a password in clear text formate.
