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.
Crack Xp Password Rainbow Tables Hacking
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.
The rainbow table itself refers to a precomputed table that contains the password hash value for each plain text character used during the authentication process. If hackers gain access to the list of password hashes, they can crack all passwords very quickly with a rainbow table.
Hackers must first gain access to leaked hashes in order to carry out rainbow table attacks. The password database itself might be poorly secured, or they may have gained access to the Active Directory. Others gain access through phishing techniques of those that might have access to the password database. On top of all these techniques, there are already millions and millions of leaked password hashes on the dark web that are available to hackers.
According to the official website, Cain & Abel is a password recovery tool for Microsoft Operating Systems. It allows easy recovery of various kinds of passwords by sniffing the network, cracking encrypted passwords using Dictionary, Brute-Force and Cryptanalysis attacks, recording VoIP conversations, decoding scrambled passwords, recovering wireless network keys, revealing password boxes, uncovering cached passwords and analyzing routing protocols.
The latest version is faster and contains a lot of new features like APR (ARP Poison Routing) which enables sniffing on switched LANs and Man-in-the-Middle attacks. The sniffer in this version can also analyze encrypted protocols such as SSH-1 and HTTPS and contains filters to capture credentials from a wide range of authentication mechanisms. The new version also ships routing protocols authentication monitors and routes extractors, dictionary and brute-force crackers for all common hashing algorithms and for several specific authentications, password/hash calculators, cryptanalysis attacks, password decoders and some not so common utilities related to network and system security.
There are many tools that create a rainbow table and there are many rainbow tables already available on the internet.Fortunately, Cain comes with a tool called winrtgen, which is located in its own folder in the installation.
That's where Ophcrack comes in. Ophcrack is one of the more effective password hack tools that runs via Windows, Mac and Linux installations or on a Live CD, and it can be used to crack almost any Windows password.
To manage this, Ophcrack uses rainbow tables to guess the password. When a working one is encountered, it is presented to you, and you can simply log in with it. One would think this "guessing" takes a lot of time, but that's just where the power of rainbow tables lies.
A rainbow table is basically an enormous list of passwords -- basically every password a brute force attack would try -- with their respective hashes included. Although this table takes a lot of time to generate, it can reduce the cracking of passwords to minutes, or even seconds.
Ophcrack supplies a few of these rainbow tables, free, for your use. They're included in the Live CD, can automatically be retrieved from the Windows executable, or downloaded from the Ophcrack website. We'll quickly look over the available tables, and their possibilities.
For Windows XP, Ophcrack supplies two alphanumeric tables. With these, you can crack 99.99% of all passwords under 14 characters, consisting of a combination between letters and numbers -- abcdefghijklmnopqrstuvwxyz0123456789. Because the LM hash used by Windows XP is insensitive to capitalization, these hash tables contain 80 billion different hashes, corresponding with 12 septillion possible passwords.
You can choose between the XP free small and the XP free fast tables. These can both be used to crack the same passwords, but because the XP free fast table is twice as large, you can crack them in half the time.
For Windows Vista, which abandoned the weak LM hash, and moved on to the stronger NT hash, there are less possibilities. Currently, Ophcrack only gives away a table with dictionary-words and variations (hybrids) for free. If you're willing to cough up a lot of money (about 99$), they also provide alphanumerical tables - including special characters.
Because the NT hash is subjective to capitalization, and allows a much greater password length (whereas the LM hash simply splits large sequences up in multitudes of smaller strings), these premium rainbow tables can range in size from 8GB to over 130GB.
So, what do you think? Is Ophcrack really the pot of gold at the end of the rainbow, or hardly worth one's attention? -- Let us know your experiences, opinions and questions in the comments section below.
Cracking a Windows Password with Ophcrack with the use of rainbow tables, relatively easy if you take the right steps and if the computer can boot from a disc. The free, open source Ophcrack Live CD is a Windows account password cracking tool designed to help you recover lost Windows passwords. Whether you need to recover the lost password to a Windows account, you're looking to ensure that your passwords are secure, or you're a super l33t h4x0r, the Ophcrack Live CD is a pretty useful tool. The Ophcrack Project has recently released a Linux Live-CD based on SLAX that can be used to retrieve and crack passwords from Windows machines with little or no effort.
These more complicated passwords are considered "strong" because they take a longer time to crack than shorter, easier-to-guess passwords. But even strong passwords can be cracked in seconds using an open source tool called Ophcrack.
Ophcrack is an extremely fast password cracker because it uses a special algorithm called rainbow tables. Brute-force cracking tools typically try thousands of combinations of letters, numbers and special characters each second, but cracking a password by attempting every conceivable combination can take hours or days. Rainbow tables pre-computes the hashes used by passwords, allowing for a speedy password lookup by comparing the hashes it has, instead of computing them from scratch.
Thinking of it another way, someone else has already generated the password hashes for millions of potential passwords using the same algorithm as Windows XP and Vista. Ophcrack simply loads the megabytes of hashes it already has and compares the password hash in Windows against its giant database. When it finds a match, Ophcrack reveals the password in plain text. 2ff7e9595c
