Password Cracking Tools For Use In 2021
Password cracking or ‘password hacking’ as is it more commonly referred to is a cornerstone of Cybersecurity and security in general.
Wanting to crack passwords and the security therein is likely the oldest and most in-demand skills that any InfoSec professional needs to understand and deploy.
Password hacking software has evolved tremendously over the last few years but essentially it comes down to several things: firstly, what systems are in place to prevent certain popular types of password cracking techniques (for example ‘captcha forms’ for brute force attacks), and secondly, what is the computing processing power of the hacker?
Typically password hacking involves a hacker brute-forcing their way into a website admin panel (or login page for example) and bombarding the server with millions of variations to enter the system.
That requires CPU. The faster the machine the faster the cracking process will be. Yes, a ‘clued-up’ Cybersecurity Professional will be able to prevent brute-forcing but you’ll be amazed at the number of vulnerable websites that can be forced into with the password hacking software that we’ve listed below.
Humans Are Lazy, Good News For A Hacker
We are all lazy.
I am, you are, and you’ll find ways to make your life more efficient and easier and why shouldn’t you!
Unfortunately, convenience is something that does not play nice with Cybersecurity and especially with regards to password security. The more complex your password the more it will be difficult for a hacker to force their way into your account(s).
There are a bunch of password security measures we can all take which will greatly help your security online and many of these we already know extremely well yes few of us really adopt them. For example, do not use the same password – because should a breach happen on one system you’re entire (or potentially a large chunk) of your online presence may also be compromised.

This tool focuses on areas of Wifi Security which includes monitoring which captures packets and exports the data to text files for processing by 3rd party tools. Replaying attacks, fake access points, deauthentication by using packet injection. Testing of wifi cards and driver capabilities via capture and injection and cracking of WPA and WPA PSK (WPA 1 and WPA 2).
Crowbar Password Tool
It’s a little tricky to get going but once you realize the power that Crowbar packs then you’ll be brute-forcing your way into any server you wish.
Crowbar is one of the brute force attacking tools that provides you an opportunity to be in control of what is submitted to a web server.
It doesn’t try to identify a positive response like hitting a correct username or password combination but it rather tells you to give a “baseline” – the content of response and content of the baseline are then compared.
Is Crowbar Free?
Yes, Crowbar is currently free.
Does Crowbar Work on all Operating Systems?
Crowbar works with Linux operating systems.
What are the Typical Uses for Crowbar?
This brute-forcing tool is commonly used during penetration tests and is developed to support protocols that are currently not supported by other brute-forcing tools. Currently, this tool supports remote Desktop Protocol with NLA support, VNC key authentication, open VPN and SSH private key authentication.
John The Ripper (‘JTR’ or ‘John)’
Aside from having the best possible name, I love John, as it is affectionately known because simply said, it works and is highly effective. John The Ripper is, like Metasploit, also part of the Rapid7 family of pentesting/ hacking tools.
How do Password Crackers Work?
In cryptanalysis, (which is the study of cryptographic systems in order to attempt to understand how it operates, and, as hackers, we’ll try to see if there are any vulnerabilities that will allow them to be broken, with or without the hash/ password key).
Password cracking is the process of recovering or hacking passwords from data that have been stored in or has been transmitted by a computer system or within a network.
One of the most common types of password hacking is known as a ‘brute-force attack.’ which, simply said, is the process in which a computer system guesses for the correct by cross-checking against an available cryptographic hash of the password. If the brute force attack is against clear-text words then the process derives from a ‘dictionary-attack’.
If the password is guessed using password hashes (which is faster), then the user process would be a ‘rainbow’ table.
If you work in Cyber Security or are looking to get started in the profession, then it is ‘a must’ that you learn certain aspects of cryptography.
We’d therefore strongly suggest that you learn, and try to crack, offline passwords using John The Ripper.
How does John The Ripper compare to THC Hydra?
THC Hydra, or simply ‘Hydra’, is another very popular password hacking tool that is often referred to in the same context as John The Ripper. The easiest way to describe the difference between John The Ripper (JTR) and THC Hydra is that JTR is an offline password cracker whilst Hydra is an online password cracker.
Is John The Ripper Free?
Both. There is a very popular free version of John The Ripper, and also a ‘pro’ version. John the Ripper commercial version is used by penetration testers that are interested in password cracking specific operating systems. The commercial version optimized for performance and speed. For the average user John The Ripper ‘open-source’ will work great, for the real hard-core user we’d certainly recommend the Pro Version, available from Rapid7.
Does John The Ripper Work on all Operating Systems?
John The Ripper was originally developed for Unix operating systems but now runs on various platforms 11 of which are architecture-specific versions of DOS, Unix, BeOS, Win32, and OpenVMS.
What are Typical Uses for John The Ripper?
John the Ripper is a fast password cracker. Period. In fact, you can consider John The Ripper as ‘the definitive’ password hacking tool!
In summary, this extremely popular password cracking software tool is a behemoth within its’ category.
This tool now works on, literally, every single platform you can think of.
Users of this software love it, primarily for two specific reasons; firstly, because you can combine it with other password crackers, and secondly because it can autodetect password hash types through its customizable cracking functionality.
This tool can easily be executed against various encrypted password formats including (but not limited to) several crypt password hash types most commonly found on various Unix versions (such as DES, MD5, or Blowfish, Kerberos AFS, etc).
Like other tools such as Metasploit and Nmap, John The Ripper (JTR) can have its performance enhanced by adding extra modules.
L0phtCrack is a recovery and password auditing tool originally created by Mudge – a hacker who has been in the game for a long time. My review is a little limited if I’m honest but from what I heard and saw of it several years ago now was impressive.
It tries to crack Windows passwords from obtained hashes from stand-alone Windows workstation, primary domain controllers, networked servers or Active Directory. It can sometimes sniff hashes off the wire. This tool also has several methods of generating password guesses.
Is L0phtCrack Free?
Nope. There are three versions available for L0phtCrack: Professional, Administrator, and Consultant are available for purchase.
Does L0phtCrack Work on all Operating Systems?
No, It only works for Microsoft Windows.
What are the Typical Uses for L0phtCrack?
L0phtCrack is used to recover lost Microsoft Windows passwords or to test someone’s password strength. It uses brute force, rainbow tables, hybrid, dictionary attacks, and a combination therein. Even if this one of the tools of choice, crackers use old versions because of their high availability and low price.
The best thing about this password cracker is its’ speed. I was running a low spec machine and it was able to brute-force into a local machine I had on my network with a relatively difficult password.
Medusa is created to be a massively parallel, modular, speedy, and login brute forcer.
The aim is to support a lot of services that will allow remote authentication.
Key features of this tool include thread-based parallel testing – Brute force testing can be performed against multiple hosts, passwords or users. Flexible user input – Target information can be specified in different ways.
One example is that for each item, it can be either a single entry or file containing multiple entries and Modular design – Every independent mod file exists in each service mod file. This means that no modifications are needed to the core application in order to extend the list of supported services for brute-forcing.
Is Medusa Free?
Yes, Medusa is free to use.
Does Medusa Work on all Operating Systems?

How Hard Is It To Break A Password Composed Of 8 Characters?
The accepted answers are that of course, it depends on the processing power of your machine (or the system that is running the password hacking method). To put that into numbers, if you’re on a basic low-spec computer that was running a brute-force hack then it will take (1.7*10^-6 * 52^8) seconds / 2, or 1.44 years. The faster the processor the less that number becomes. A supercomputer or a botnet powered tool would take a lot less time (maybe about ten minutes at best). The moral of the story here is to have a complex password that is longer than eight characters.
How Can I Hack A Password?
Brute Force Attack and social engineering scams are the two easiest and best-known methods of being able to hack passwords. Most password cracking tools can crack simple passwords by guessing a specific number of passwords (see tools like cup.py). Hackers use tools listed within our resource that will try to crack passwords by simply entering different passwords over and over until it’s cracked. There’s more to it than this but essentially that’s how passwords are cracked. The other solution is social engineering. Uber was hacked, for example, because some developers left login credentials on their GitHub account. Such an error was human, but the access to their GitHub account was likely due to social engineering.
What Are Five Recognized Processes Of Hacking?
The five stages are: Reconnaissance > Scanning > Gaining Access > Maintaining Access > Covering Tracks.
Can I Hacked A Computer By Just Using An Ip Address?
Yes and no.
Yes, because of its practice you certainly can scan the IP to see what’s on it and from that information launch at attack but likely that will be very difficult because even rudimentary client-facing ports (IP Addresses) will have some form of firewall or packet filtering.
Also, typically, a semi-decent Firewall will be able to instantly detect a Nmap scan (for example) and block the origin IP and subsequently rotated IP’s. An expert hacker or Penetration Tester can send creative packets to test the system and may be able to penetrate the network or IP Address. In summary, therefore, the best answer is: it depends!
Is It Possible To Hack A Mobile?
Yes, but it would require a significant skill. There is a multitude of ways to hack into someone’s phone. The easiest way would be to get the target to download a vulnerable “mobile app” that could then be used to remotely access that targets phone.
Also, this question is almost impossible to answer in a “yes” or “no” but in summary, I’d say that a mobile phone (iOS or Android) is, of course, a computer and therefore can be hacked so I’d lean towards always saying “yes” mobile phone can be hacked. How easy that is, of course, depends on a wide range of factors.
How Hard Is It To Break A Password?
The answer here is that it totally depends. Using creative hacking tools you can create specific dictionary attacks based upon your target which would be really focused on getting the correct pattern or likely passwords. Such an attack would be referred to as a “Brute Force” attack. So, in summary – the harder the password the harder it is to crack! Get creative and have unique passwords per account.
Can I Hack A 4 Digit Pin In A Short Period Of Time?
Based upon research we’ve looked at here at Concise Courses each PIN entry can take about 40 seconds to execute. Based upon that metric it would take over 112 to brute force a 4 digit PIN.
What Is The Primary Stage Of Password Hacking?
The first step of password hacking is known as “Footprinting (Reconnaissance) or “Information Gathering”. This phase is also known as OSINT (Open Source Intelligence) where the hacker (or “Ethical Hacker”) would collect as much information as possible about their target and with regards to password cracking they’d have to create their own unique rainbow/password list.
