Password Cracking is the process of recovering passwords from data that have been stored in or transmitted by a computer system. A common approach (brute-force attack) is to try guesses repeatedly for the password and check them against an available cryptographic hash of the password.
The purpose of password cracking might be to help a user recover a forgotten password (installing an entirely new password is less of a security risk, but it involves System Administration privileges), to gain unauthorized access to a system, or as a preventive measure by system administrators to check for easily crackable passwords. On a file-by-file basis, password cracking is utilized to gain access to digital evidence for which a judge has allowed access.
A secret string of characters is used for the authentication process in various applications is called a password. It is used to gain access to various accounts, repositories, and databases but at the same time, protects them from unauthorized access.
On the event of losing a password due to inability of recollection, there are certain processes through which a person may have to go to bring back or change the password.
Industries in which passwords are a high priority:
-Banking & Finance
-Telecommunication & Gadgets
Types of Cybersecurity Attacks which aim to crack passwords:
Brute Force Attack
A brute force attack may not try all options in sequential order. An advanced brute force attack can make certain assumptions like complexity rules require uppercase, first character more likely to be upper than lower case.
In this type of attack, the hacker tries to determine the password by trying every possible combination of characters.
The dictionary/possible combinations are based on some possible values and tend not to consider options of remote possibility. It may be based on the knowledge of one or a few key information about the target (family member names, birthday, etc.). The dictionary is based on the patterns or combinations that were observed across a massive number of users to determine the most commonly used patterns.
The dictionary attack’s execution time is reduced because the number of combinations is restricted only to those on the list.
It is a precomputed table for reversing cryptographic hash functions, mostly used for cracking password hashes. This technique proves to be good for recovering plaintext passwords, debit card numbers, etc. up to a limited length which consists of a limited group of characters.
Best Password Cracking tools
One of the widely used remote online tools used for password-cracking is Brutus. Brutus claims to be the fastest paced and flexible password cracking tool.
This tool supports the multi-stage authentication engines and is also capable of connecting with 60 simultaneous targets. Resume and Load are two of its good features. Using these features, one can halt the attack process any time and then resume whenever one would want to resume.
It falls in the hash cracker tool category that utilizes a large-scale time-memory trade off process for faster password cracking compared to traditional brute force tools. Time & memory trade-off is a process of computation where all plain text and hash pairs get calculated by using a chosen hash algorithm.
RainbowCrack’s makers have been successful in generating rainbow tables (LM), md 5 rainbow table, rainbow table (NTLM), and sha 1 rainbow table.
Cain & Abel
Cain and Abel is a popular password cracking tool. Is can handle varying tasks. The most noticeable thing is the tool’s availability only in Windows platforms. It can function as a sniffer on the network, for cracking of encrypted passwords by the dictionary attack, uncovering cached passwords, decoding scrambled passwords, brute attacks, recording VoIP conversations, password boxes revelation, cryptanalysis attacks, and analysing protocols of routing.
Medusa is another password cracking tool. It is known to be a speedy parallel, login brute forcing tool and modular. When cracking the password; host, password and username can be a flexible input while the performance of the attack.
Medusa is popular for being the command line tool, so one need to understand commands before utilizing the tool. Tool’s efficiency depends on network’s connectivity. It can test 2000 passwords per minute on a local system.
Things to Be Considered While Creating a Password:
-Upper & Lower case
-Username not be used as a password.
-Make it difficult to crack.
-Do not use known things to people about yourself like birthdate.
-Dictionary words are not to be used.
-Do not use key strokes adjacent to each other like “1234”, etc.
-Avoid the exact same password everywhere.
-Do not store the passwords as a list on the system.
-There are online third-party services that help users to safeguard sensitive passwords, along with LastPass, DashLane, and 1Password that store passwords at the cloud and secure them all using a master password.
Password cracking tools are however used with various motives, sometimes negative other times, positive. Being aware of such software enlightens the people especially in the information technology and security domain. In the study of information security, such applications are taught with more detail. There are certain applications available to reduce the chances of such attacks through the above mentioned tools and techniques. Whether it is a password for bank account, broking account, social media account or a document password it is ought to be made unbreakable to ensure its utmost security and avoiding unauthorized access.
