Hashcat enables highly-parallelized password cracking with the ability to crack multiple different passwords on multiple different devices at the same time and the ability to support a distributed hash-cracking system via overlays. Cracking is optimized with integrated performance tuning and temperature monitoring.
John the Ripper offers password cracking for a variety of different password types. It goes beyond OS passwords to include common web apps (like WordPress), compressed archives, document files (Microsoft Office files, PDFs and so on), and more.
Brutus is one of the most popular remote online password-cracking tools. It claims to be the fastest and most flexible password cracking tool. This tool is free and is only available for Windows systems. It was released back in October 2000.
Brutus has not been updated for several years. However, its support for a wide variety of authentication protocols and ability to add custom modules make it a popular tool for online password cracking attacks.
Wfuzz is a web application password-cracking tool like Brutus that tries to crack passwords via a brute-force guessing attack. It can also be used to find hidden resources like directories, servlets and scripts. Wfuzz can also identify injection vulnerabilities within an application such as SQL injection, XSS injection and LDAP injection.
Medusa is an online password-cracking tool similar to THC Hydra. It claims to be a speedy parallel, modular and login brute-forcing tool. It supports HTTP, FTP, CVS, AFP, IMAP, MS SQL, MYSQL, NCP, NNTP, POP3, PostgreSQL, pcAnywhere, rlogin, SMB, rsh, SMTP, SNMP, SSH, SVN, VNC, VmAuthd and Telnet.
Medusa is a command-line tool, so some level of command-line knowledge is necessary to use it. Password-cracking speed depends on network connectivity. On a local system, it can test 2,000 passwords per minute.
RainbowCrack is a password cracking tool designed to work using rainbow tables. It is possible to generate custom rainbow tables or take advantage of preexisting ones downloaded from the internet. RainbowCrack offers free downloads of rainbow tables for the LANMAN, NTLM, MD5 and SHA1 password systems.
OphCrack is a free rainbow table-based password cracking tool for Windows. It is the most popular Windows password cracking tool but can also be used on Linux and Mac systems. It cracks LM and NTLM hashes. For cracking Windows XP, Vista and Windows 7, free rainbow tables are also available.
L0phtCrack is an alternative to OphCrack. It attempts to crack Windows passwords from hashes. For cracking passwords, it uses Windows workstations, network servers, primary domain controllers and Active Directory. It also uses dictionary and brute-force attacks for generating and guessing passwords. It was acquired by Symantec and discontinued in 2006. Later, L0pht developers again reacquired it and launched L0phtCrack in 2009.
Aircrack-ng is a Wi-Fi password-cracking tool that can crack WEP or WPA/WPA2 PSK passwords. It analyzes wireless encrypted packets and then tries to crack passwords via the dictionary attacks and the PTW, FMS and other cracking algorithms. It is available for Linux and Windows systems. A live CD of Aircrack is also available.
In this post, we have listed 10 password-cracking tools. These tools try to crack passwords with different password-cracking algorithms. Most of the password cracking tools are available for free. So, you should always try to have a strong password that is hard to crack. These are a few tips you can try while creating a password.
Password-cracking tools are designed to take the password hashes leaked during a data breach or stolen using an attack and extract the original passwords from them. They accomplish this by taking advantage of the use of weak passwords or by trying every potential password of a given length.
Next, we will be attempting to crack the password on the Damn Vulnerable Web Application (DVWA). You can run it from the Metasploitable operating system (available at Rapid7) and then connecting to its login page, as I have here.
A few things to note. First, you use the upper case "L" if you are using a username list and a lower case "l" if you are trying to crack one username that you supply there. In this case, I will be using the lower case "l " as I will only be trying to crack the "admin" password.
Although THC-Hydra is an effective and excellent tool for online password cracking, when using it in web forms, it takes a bit of practice. The key to successfully using it in web forms is determining how the form responds differently to a failed login versus a successful login. In the example above, we identified the failed login message, but we could have identified the successful message and used that instead. To use the successful message, we would replace the failed login message with "S=successful message" such as this:
You can get it using tamper data. It's an addon. Go to addons and search for tamper data and install it. Then navigate to the login page and fill out the user name and password. Before clicking submit, open the tamper data tool and click 'start tamper'. Hit submit button on the website. A pop up will ask you whether you'd like to tamper, discard, or submit. Hit submit. Then look through the entries in tamper data and click on it. It will give you the request along with the post data. This works best if no other website is open; just the one you're trying to log into. Otherwise you're going to get a lot of pop ups asking you whether you'd like to tamper, in which case you could just discard, but it's harder to find request you're looking for. Hope this helps. I saw OTW did an article about how to crack passwords using tamper data and hydra. It's the same concept as when using burp essentially. I'm sure it provides a better instruction
Hey OTW, really well explained tutorial, I have a question though : should I use proxy with hydra if I want to crack password for ONE account let's say my friend's Facebook account? Will I get an ip ban or something like that ? And BTW , I really want to know if you could make a tutorial on how in Mr.robot episode 1, Elliot hacked his psy's password by simply adding custom word to a dictionary and instant cracking. I know you can do it with crunch but it is only creating wordlist.
Hey OTW ! Your tutorials are vey well explained and I'm learning a lot. Could you please tell me if I should use a proxy list in order to crack an online account with crunch and hydra ? And can you teach us how did Elliot cracked his target's password in episode 1 of Mr. Robot ? They way he adds password to a password list and instantly run the brute force . I'm waiting for your answers , thank you .
sorry for double post and thanks for the reply, now that i managed to use CUPP this magical password creator, any clue on which type of password he cracked ? Most online passwords has a tries/ip or tries/account limitaion, he treid a 90k password list :o
Great tutorial. However, I do not think this technique will work with a particular router I have. The router's login page uses a Java applet. Any idea how I can approach cracking the password. Using hydra SSH gives me an error of password authentication not supported.
Hey i know this is an old post, need some help with the following. i,m trying to crack the login for the attached localhost form, can someone share what command i need to apply in thc hydra. i get passwords but they are incorrect & do not work. thanks,
Hashcat supports five unique modes of attack for over 300 highly-optimizedhashing algorithms. hashcat currently supports CPUs, GPUs, and otherhardware accelerators on Linux, and has facilities to help enabledistributed password cracking.
According to a study conducted by Verizon, 63% of data breaches involved leveraging default, weak or stolen passwords. When it comes to complex networks and online environments, just one cracked password has a quickly cascading effect. The 2012 data breach at LinkedIn was caused by a Russian hacker who used one weak password to expose 6.5 million encrypted passwords. Several years later 117 million email addresses and their password combinations tied to LinkedIn users were for sale on the black market.
Password cracking tools can also be used by system administrators to check for easily hackable passwords. Although traditionally perceived to be used exclusively for criminal purposes, using password hacking tools to test or recover lost passwords is a legal practice. The best password cracker apps can handle multiple targets simultaneously, are usable on different platforms, and support multiple protocols.
John the Ripper is a good choice for a password cracking tool, mainly because of its open-source nature and support for different platforms. The open-source nature means that the code is available to the public, so users do not have to worry about the legality of the software and about potential malware of malicious programs that might be deeply integrated into the software.
John the Ripper is safe to use as it runs under the same user privileges for every other program by the user. As for privacy, the cracked password is shown or given only to the user; it is up to each user to take steps to prevent unauthorized access by other users.
Hashcat does not store any cracked passwords on its servers, ensuring that any passwords deciphered by the user are given to that user alone. For this reason, it is possible to say that Hashcat provides privacy.
Medusa is an online password-cracking tool that supports plenty of protocols, including HTTP, SSH, FTP, CVS, AFP, POP3, Telnet, and more. The software works as a login brute-forcer; many credentials using as many protocols as possible are inputted to arrive at the correct password.
THC Hydra has seen many comparisons to Medusa as a password cracker, but there are notable differences between the two software. Like Medusa, THC Hydra is also an online password cracking tool that uses a brute-force password guessing method. One key difference is that THC Hydra can be installed on Windows, macOS, Linux, Free BSD, and Solaris, notably more platforms than Medusa supports. In addition to the brute-force method, THC Hydra can also use dictionary attacks, using external wordlists. 2b1af7f3a8
