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.
I've seen John the Ripper mentioned a lot for cracking passwords, I've gotten as far as getting a build (1.7.9-jumbo-7 [macosx-x86-64]) installed. I have a word list ready and a vague idea of what my pass could be, I'm just not sure where to go from here.
Johnny is the cross-platform Open Source GUI frontend for the popular password cracker John the Ripper. It was originally proposed and designed by Shinnok in draft, version 1.0 implementation was achieved by Aleksey Cherepanov as part of GSoC 2012 and Mathieu Laprise took Johnny further towards 2.0 and beyond as part of GSoC 2015.
Johnny's aim is to automate and simplify the password cracking routine with the help of the tremendously versatile and robust John the Ripper, as well as add extra functionality on top of it, specific to Desktop and GUI paradigms, like improved hash and password workflow, multiple attacks and session management, easily define complex attack rules, visual feedback and statistics, all of it on top of the immense capabilities and features offered by both JtR core/proper as well as jumbo.
To figure out the target's Mac password without changing it, the hash will need to be brute-forced and cracked. MacOS does an excellent job of securing the target's password. It's not possible to view user passwords in plain-text. CPU-based cracking solutions (like JohnTheRipper) will literally take decades to crack a single hash and are therefore not effective. Hashcat with a decent GPU is highly recommended.
Below is the JtR command from our Live Cyber Attack Webinar. In this scenario, our hacker used kerberoast to steal a Kerberos ticket granting ticket(TGT) containing the hash to be cracked, which was saved in a file called ticket.txt. In our case, the wordlist used is the classic rockyou password file from Kali Linux, and the command was set to report progress every 3 seconds.
Now to crack the password, John the Ripper will identify all potential passwords in a hashed format. It will then match the hashed passwords with the initial hashed password and try to find a match.
If a match is found in the password hash, John the Ripper then displays the password in raw form as the cracked password. The process of matching the password hashes to locate a match is known as a dictionary attack.
DaveGrohl is a brute-force password cracker for macOS. It was originally created in 2010 as a password hash extractor but has since evolved into a standalone or distributed password cracker. DaveGrohl supports all of the standard Mac OS X user password hashes (MD4, SHA-512 and PBKDF2)[1][2][3] used since OS X Lion and also can extract them formatted for other popular password crackers like John the Ripper.[4] The latest stable release is designed specifically for Mac OS X Lion and Mountain Lion.
The Cybrscore Open Source Password Cracking lab teaches students how to use the open source tool, John the Ripper, to crack passwords of various file types on both a Windows and a Linux virtual machine. John the Ripper is an open source offline password cracking tool used on multiple platforms, including Linux, Unix, Mac OS X, and Windows. This tool is used to detect weak passwords that can put system or application security at risk. John the Ripper has the capability to autodetect password hash types and uses customized modules for different hash types and processor architectures, including MD5, SHA-1, Kerberos TGTs, Open SSH private keys, ZIP and RAR archive archives.
In the Cybrscore Open Source Password Cracking lab, students will learn how to use the tool Cain and Abel to crack various passwords on a Windows machine. Cain and Abel is an offline password cracking tool designed for use only on Windows platforms. It is a powerful tool that has multiple different capabilities to crack passwords, including using a dictionary attack method to crack encrypted passwords, decode scrambled passwords, and uncover cached passwords. This program leverages weaknesses in security protocol weaknesses to crack passwords.
John the Ripper (JTR) is a free, open-source software tool used by hackers, both ethical and otherwise, for password cracking. The software is typically used in a UNIV/Linux and Mac OS X environment where it can detect weak passwords.
John the Ripper is fast and replete with many key features. JTR combines several cracking modes in one program and is fully configurable. Also, JTR is available for several different platforms which enables you to use the same password cracking tool everywhere.
We know the importance of John the ripper in penetration testing, as it is quite popular among password cracking tool. In this article, we are introducing John the ripper and its various usage for beginners.
John the Ripper is a free password cracking software tool developed by Openwall. Originally developed for Unix Operating Systems but later on developed for other platforms as well. It is one of the most popular password testings and breaking programs as it combines a number of password crackers into one package, autodetects password hash types, and includes a customizable cracker. It can be run against various encrypted password formats including several crypt password hash types commonly found in Linux or Windows. It can also be to crack passwords of Compressed files like ZIP and also Documents files like PDF.
In this mode John the ripper uses a wordlist that can also be called a Dictionary and it compares the hashes of the words present in the Dictionary with the password hash. We can use any desired wordlist. John also comes in build with a password.lst which contains most of the common passwords.
John the Ripper is a fast password cracker, currently available for many flavors of Unix, macOS, Windows, DOS, BeOS, and OpenVMS (the latter requires a contributed patch). Its primary purpose is to detect weak Unix passwords. Besides several crypt(3) password hash types most commonly found on various Unix flavors, supported out of the box are Kerberos/AFS and Windows LM hashes, as well as DES-based tripcodes, plus hundreds of additional hashes and ciphers in "-jumbo" versions.
JohnTheRipper, as mentioned at the beginning of the article is not related by itself to PDFs, but to passwords and security stuff. That's why you will need to create the hash file of the PDF using the pdf2john.pl tool (available in the run directory after compiling from source). This tool allows you to obtain the hash (Read meta information) of the file through this perl script, which can be extracted into a new file with the following command: 2ff7e9595c
