Top 10 Password Cracking Tools

A simple detail about password cracking tools from the wiki. In cryptanalysis and computer security, password cracking is the process of recovering passwords from data that have been stored in or transmitted by a computer system. A standard approach (brute-force attack) is to try guesses repeatedly for the password and check them against an available cryptographic hash of the password. Password cracker is not hacking a password; this software only recovers your password. Got it? So don’t use against someone’s system or illegally.

The other purposes of password cracking tools might be to help a user recover a forgotten password of a system or any software. But in the world of hacking, hackers are using such a tools to break or crack the stolen password hashes of a database. Or using them to hack the wireless network and crack the passwords. So hope you completely understand the primary purpose of password cracking tools.

#1. OphCrack

It is a free Windows password cracker based on rainbow tables. It is a very efficient implementation of rainbow tables done by the inventors of the method. It comes with a Graphical User Interface and runs on multiple platforms. See some features of Ophcrack password cracking tools. The uploaded version of Ophcrack compiled for Windows 64-bit platforms. This version can preload tables using the whole RAM available instead of the only 2GB on 32-bit platforms.

Features:

• Runs on Windows, Linux/Unix, Mac OS X, …
• Cracks LM and NTLM hashes.
• Free tables available for Windows XP and Vista/7/8.1.
• Brute-force module for simple passwords.
• Audit mode and CSV export.
• Real-time graphs to analyse the passwords.
• Live CD available to simplify the cracking.
• Dumps and loads hashes from encrypted SAM recovered from a Windows partition.
• Free and open source software (GPL).

Download the latest Ophcrack version from Sourceforge, the open source software storage.

2. RainbowCrack

The RainbowCrack password cracking tools is a general propose implementation of Philippe Oechslin’s faster time-memory trade-off technique. It cracks hashes with rainbow tables. RainbowCrack uses time-memory tradeoff algorithm to crack hashes. It differs from brute force hash crackers.

A brute force hash cracker generates all possible plaintexts and compute the corresponding hashes on the fly, then compare the hashes with the hash to be cracked. Once a match is found, the plaintext is found. If all possible plaintexts are tested, and no match is found, the plaintext is not found. With this type of hash cracking, all intermediate computation results are discarded.

Features:

• Full time-memory tradeoff tool suites, including rainbow table generation, sort, conversion and lookup
• Support rainbow table of any hash algorithm
• Support rainbow table of any charset
• Support rainbow table in raw file format (.rt) and compact file format (.rtc)
• Computation on multi-core processor support
• GPU acceleration with NVIDIA GPUs (CUDA technology)
• GPU acceleration with AMD GPUs (OpenCL technology)
• GPU acceleration with multiple GPUs
• Runs on Windows operating systems
• Windows XP 32-bit / 64-bit
• Windows Vista 32-bit / 64-bit
• Windows 7 32-bit / 64-bit
• Windows 8 32-bit / 64-bit
• Runs on Linux operating systems (x86 and x86_64)
• Unified rainbow table file format on all supported operating systems
• Command line user interface
• Graphics user interface

3. HashCat

Hashcat is the world’s fastest CPU-based password recovery tool. While it’s not as fast as its GPU counterpart oclHashcat, extensive lists can be easily split in half with a good dictionary and a bit of knowledge of the command switches.

Hashcat was written somewhere in the middle of 2009. Yes, there were already close-to-perfect working tools supporting rule-based attacks like “PasswordsPro”, “John The Ripper”. However, for some unknown reason, both of them did not support multi-threading. That was the only reason to write Hashcat: To make use of the multiple cores of modern CPUs.

Features: 

• Worlds fastest password cracker
• Worlds first and only GPGPU based rule engine
• Free
• Multi-GPU (up to 128 GPUs)
• Multi-Hash (up to 100 million hashes)
• Multi-OS (Linux & Windows native binaries)
• Multi-Platform (OpenCL & CUDA support)
• Multi-Algo (see below)
• Low resource utilisation, you can still watch movies or play games while cracking
• Focuses highly iterated modern hashes
• Focuses dictionary based attacks
• Supports distributed cracking
• Supports pause/resume while cracking
• Supports sessions
• Supports restore
• Supports reading words from file
• Supports reading words from stdin
• Supports hex-salt
• Supports hex-charset
• Built-in benchmarking system
• Integrated thermal watchdog
• 150+ Algorithms implemented with performance in mind
• and much more

4. Cain & Abel

It is a password recovery tool for Microsoft Operating Systems. It allows easy recovery of various kind of passwords by sniffing the network, cracking encrypted passwords using Dictionary, Brute-Force and Cryptanalysis attacks, recording VoIP conversations, decoding scrambled passwords.

It also helps you for recovering wireless network keys, revealing password boxes, uncovering cached passwords and analysing routing protocols. The program does not exploit any software vulnerabilities or bugs that could not be fixed with little effort. It covers some security aspects/weakness present in protocol’s standards, authentication methods and caching mechanisms; its main purpose is the simplified recovery of passwords and credentials from various sources. However, it also ships some “non-standard” utilities for Microsoft Windows users.

11. Medusa

The Medusa password Cracking tool is intended to be a speedy, massively parallel, modular, login brute-forcer. The goal is to support as many services which allow remote authentication as possible. The author considers following items as some of the key features of this application:

Features:

• Thread-based parallel testing. Brute-force testing can be performed against multiple hosts, users or passwords concurrently.
• Flexible user input. Target information (host/user/password) can be specified in a variety of ways. For example, each item can be either a single entry or a file containing multiple entries. Additionally, a combination file format allows the user to refine their target listing.
• Modular design. Each service module exists as an independent .mod file. It means that no modifications are necessary to the core application to extend the supported list of services for brute-forcing.
• Multiple protocols supported. Many services are currently supported (e.g. SMB, HTTP, POP3, MS-SQL, SSHv2, among others).

Download the latest Medusa tools from the foofus website which support the fgdump tool for mass password Auditing of Windows Systems. It is also a best cracking tool.
