In simple English, if an adversary wanted to hack/crack a WiFi password, they need to be in the right place (between users and a router) at the right time (when users log in) and be lucky (users entered the correct password and all four packets were sniffed correctly).
Cracking the PMKID hash is ultimately just generating/calculating PMKs with the SSID and different passphrases, then calculating PMKID from the PMK and the other information we obtained. Once we generated a PMKID equal to the PMKID that was retrieved from the AP (Figure 3), the hash is cracked; the passphrases that were used to generate the right PMK that the PMKID was generated from is the correct WiFi password.
Each digit has 10 options (0-9), hence 10**8 possible combinations. One hundred million seems like a lot of combinations, but our monster rig calculates at the speed of 6819.8 kH/s which translates into 6,819,000 hashes per second.A cracking rig is not required as my laptop can get to 194.4 kH/s, which translates into 194,000 hashes per second. That equals more than enough computing power to cycle through the possibilities necessary to crack the passwords. Consequently, it took my laptop roughly 9 minutes to break a single WiFi password with the characteristics of a cellphone number. (10**8)/194,000 = 516 (seconds)/60 = 9 minutes.
The cracking speed for hashtypes differs because of different hash functions and the number of iterations. For example, PMKID is very slow compared to MD5 or NTLM. Nonetheless, it is feasible to crack a PMKID hash if the attacker focuses on a specific network, and the password is not complicated enough.
I hope you enjoyed this blog and that you will take the required steps to secure your WiFi network. And as a reminder, none of the passwords we cracked were used for unauthorized access to these WiFi networks or any other information accessible via these networks.
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.
There are other ways to guard against password cracking. The simplest is well known and used by credit cards: after three unsuccessful attempts, access is blocked. Alternative ideas have also been suggested, such as doubling the waiting time after each successive failed attempt but allowing the system to reset after a long period, such as 24 hours. These methods, however, are ineffective when an attacker is able to access the system without being detected or if the system cannot be configured to interrupt and disable failed attempts.

This practice poses a serious problem for security because it makes passwords vulnerable to so-called dictionary attacks. Lists of commonly used passwords have been collected and classified according to how frequently they are used. Attackers attempt to crack passwords by going through these lists systematically. This method works remarkably well because, in the absence of specific constraints, people naturally choose simple words, surnames, first names and short sentences, which considerably limits the possibilities. In other words, the nonrandom selection of passwords essentially reduces possibility space, which decreases the average number of attempts needed to uncover a password.
In cryptanalysis and computer security, password cracking is the process of recovering passwords[1] from data that has been stored in or transmitted by a computer system in scrambled form. A common approach (brute-force attack) is to repeatedly try guesses for the password and to check them against an available cryptographic hash of the password.[2] Another type of approach is password spraying, which is often automated and occurs slowly over time in order to remain undetected, using a list of common passwords.[3]
The purpose of password cracking might be to help a user recover a forgotten password (due to the fact that installing an entirely new password would involve System Administration privileges), to gain unauthorized access to a system, or to act as a preventive measure whereby system administrators check for easily crackable passwords. On a file-by-file basis, password cracking is utilized to gain access to digital evidence to which a judge has allowed access, when a particular file's permissions restricted.
The time to crack a password is related to bit strength .mw-parser-output div.crossreferencepadding-left:0.mw-parser-output .hatnotefont-style:italic.mw-parser-output div.hatnotepadding-left:1.6em;margin-bottom:0.5em.mw-parser-output .hatnote ifont-style:normal.mw-parser-output .hatnote+link+.hatnotemargin-top:-0.5em(see Password cracking), which is a measure of the password's entropy, and the details of how the password is stored. Most methods of password cracking require the computer to produce many candidate passwords, each of which is checked. One example is brute-force cracking, in which a computer tries every possible key or password until it succeeds. With multiple processors, this time can be optimized through searching from the last possible group of symbols and the beginning at the same time, with other processors being placed to search through a designated selection of possible passwords.[4] More common methods of password cracking, such as dictionary attacks, pattern checking, word list substitution, etc. attempt to reduce the number of trials required and will usually be attempted before brute force. Higher password bit strength exponentially increases the number of candidate passwords that must be checked, on average, to recover the password and reduces the likelihood that the password will be found in any cracking dictionary.[5] 2ff7e9595c
