There are many password cracking tools available for free and paid as well. Today we are going to discuss about some most recommended password cracking tools that security professionals uses.

Aircrack

It is used to recover wireless keys. It implements the best known cracking algorithms once enough encrypted packets are gathered. Aircrack is a suite of tools for 802.11 a/b/g WEP and WPA cracking. The suite comprises of many tools like airodump, aireplay, aircrack, airdecap for capturing wireless communications packets.


Cain and Abel

Cain and Abel is Windows-only password cracking tools that many cyber security professional uses to recover passwords. It sniffs the network, cracks encrypted password using dictionary. This tool is able to attack by brute force and cryptanalysis techniques and can also record VoIP communications, uncover cache passwords, revealing password boxes and analyzing routing protocols.


THC Hydra

Most cyber security professional choose THC hydra when they need to crack remote authentication service using brute force attack. It can perform rapid dictionary attack against more than 50 protocols, which includes http, ftp, https, smb and several databases.


Ophcrack

It’s a Windows password cracking tool, although it can be run on Linux, Windows and Mac also. It includes many features like LM and NTLM hash cracking, GUI, can load hashes from encrypted SAM recovered from Windows partition and a live CD version.


Medusa

Medusa is a tool that fast, modular, and massively parallel brute force logger. It supports many protocols like AFP, cvs, ftp, http, imap, SSH and other.


Fgdump 

Fgdump is the tool for extracting NTLM and LanMan password hashesfrom Windows. Fpdump attempts to disable antivirus software before initiating. It then runs pwdump, cachedump (cached credentials dump), and pstgdump (protected storage dump). It is also capable of displaying password histories if available.


L0phtCrack

L0phtCrack is a Windows based password cracking tool, which attempts cracking using hashes. Hashes can be obtained from stand-alone Windows workstation, network servers or active directories.  It also has various methods of generating passwords (dictionary, brute force, etc).


RainbowCrack

The RainbowCrack tool is a hash cracking tool that makes use of a large-scale time-memory trade-off. An ordinary brute force cracker tries all possible plaintexts one by one, which can be time consuming for complex passwords. While, RainbowCrack uses a time-memory trade-off to do all the pre cracking-time computation and store the results in tables called "rainbow tables". It does take a long time to pre compute the tables but RainbowCrack can be hundreds of times faster than a brute force cracker once the pre-computation is finished.


Brutus

Brutus is a free and Windows-only password cracker that uses dictionary against network services of remote system to recover password. It supports http, pop3, ftp, smb, telnet, imap and other protocols.


Wfuzz

Wfuzz is a brute forcing tool for Web Applications, cyber security professionals uses this tool for finding resources like directories, servlets, scripts, bruteforcing GET and POST parameters for different kinds of injections (SQL, XSS, LDAP, etc.) and brute forcing form parameters (user/password), fuzzing and more.



Password cracking tools are not limited to these only there are many other tools as well. Many cyber security professional recommends these tools to recover passwords.

The most commonly used passwords on the internet - Research

The social networking site LinkedIn was the talking point of Infosec community this week because of the data breach of its 117 Million users. The site was initially hacked four years ago, but the results of hack are showing now. The data of its users is up for sales on dark web according to various sources.



This isn't the first time a major internet giant have fallen victim of data breach, which affected its millions of users all over the world. Last year Ashley Madison an online dating website was hacked which have led to the resignation of its CEO and destroyed the marriages of many people.
However, the question is how hackers are able to breach these highly secured websites and gain passwords of millions of users. Yes, mainly it's because of the lack of cyber security steps taken by those organizations, but the users are equally responsible for becoming a victim of these hacking attacks. 

EHacking researchers have seen that most of the passwords that are hacked previously are commonly used around the globe and most people doesn't care if their password isn't secure. The passwords leaked from the latest LinkedIn hack are similar to the hacks of past years. 

We have gathered the list of most commonly used passwords on the internet right now. List also includes the passwords leaked after the LinkedIn hack.

System Passwords Revealed by London Rail Station during BBC Documentary

During a BBC documentary on Wednesday night, system passwords at one of London's busiest railway stations had been disclosed and were exposed to viewers.

The credentials were attached to the top of a controller’s monitor used at the rail station, the passwords were revealed at about 43 minutes into the programme.



The passwords were stuck to a monitor and were visible during a scene where the two business experts went into the control room at the rail station Waterloo in London. The screenshot seems to be of the workstation on a signaller's control desk‬ which appears to be running software that controls signals and trains over‪ the final approach to Waterloo station‬.


They were taken by the dynamic duo's travels to the Wessex Integrated Control Centre, located above the platform entrances at London Waterloo railway station, manned 24 hours a day by teams of controllers from both South West Trains and Network Rail.

However by knowing a password does not indicate that it can necessarily be exploited by anyone remotely. There is a possibility that the password is for the purpose of logging into the physical desktop computer. Nonetheless, you have reduced the point of a password if you have stuck it on the very device which needs the password.

Last week BBC News ran a story discussing fears that computer systems controlling the signal system in the UK could be vulnerable to hacking attacks.

However, it has not happened for the first time that an organization has made a blunder of letting a TV company into its offices, only to discover passwords have been exposed in the background.
French TV station TV5MONDE also made a mistake at the time they were discussing how its systems were recently hacked while revealing yet more passwords at the same time.

PACK - Password Analysis & Cracking Toolkit

PACK (Password Analysis and Cracking Toolkit) is a collection of utilities developed to aid in analysis of password lists in order to enhance password cracking through pattern detection of masks, rules, character-sets and other password characteristics. The toolkit generates valid input files for Hashcat family of password crackers.





Before we can begin using the toolkit we must establish a selection criteria of password lists. Since we are looking to analyze the way people create their passwords, we must obtain as large of a sample of leaked passwords as possible. One such excellent list is based on RockYou.com compromise. This list both provides large and diverse enough collection that provides a good results for common passwords used by similar sites (e.g. social networking). The analysis obtained from this list may not work for organizations with specific password policies. As such, selecting sample input should be as close to your target as possible. In addition, try to avoid obtaining lists based on already cracked passwords as it will generate statistics bias of rules and masks used by individual(s) cracking the list and not actual users.


The most basic analysis that you can perform is simply obtaining most common length, character-set and other characteristics of passwords in the provided list. In the example below, we will use 'rockyou.txt' containing approximately 14 million passwords. Launch statsgen.py with the following command line:

$ python statsgen.py rockyou.txt

                           _
         StatsGen #.#.#   | |
          _ __   __ _  ___| | _
         | '_ \ / _` |/ __| |/ /

How To Create A Password That Won't Be Hacked








 
Every Internet user asked himself a question “What a password to use” at least once in his life. Social networks,e-mail, forums, and various website accountsrequire passwords from users. In order not to get caught up in dozens of passwords,we usually invent the most simple, easy ones, and write them everywhere, or almost everywhere. Simple combinations are the most common password variants for the majority of users. That is why even the most inexperiencedhacker can easily get access toyour mailbox, ICQ, or even youe-wallet. What you need to know the password could not steal your password? We answer this simple question.


So, what a really strong password should look like?
  • The  length of your password must be of  10  characters at least  
  • Your  password should not be a word
  • Your  password should contain letters, numbers, uppercase letters, and  various additional characters
  • Your  password should not be your  cat's name,  your date of birth, and it  shouldn't overlap with information related to you or your family

If you store areally important information, which should not get into the hands of criminals in any way, then we recommend you to changepasswordsat least once a month. This is an additional security measure recommendedby Microsoft,which issuccessfully adopted by allmajor structures, including banks. 

We offer you several ways to generate a strong password.

Perfect Passwords



This is a very simple and effective way to generate strong passwords. You do not have to install any software, register anywhere, and so on. Every time you visit a page,it generates random secure passwords visible only to you. Here you can create a password of 64 characters with a hexadecimal system, 63-character passwords with ASCII characters and consistedonly of numbers and English letters. If necessary, you use only a parof generated sequence. Anyone interested in the theoretical part of creating strong passwords can find a lot of information on the page, including the operating principles of thisservice.

PC Tools Secure Password Generator



This is a comfortable and easy to use web service. You determine the length of apassword, the parameters of certain characters inclusion and exclusion, and the number ofpasswords generated by the given parameters.

And finally, let us remind you what your password should NEVER look like:

  1. Never  use simple letters and numbers combinations. In  other words, forget  about such passwords as 123, 0987, 1234567890, iiii, zzz, qwert etc. According to hackers, they  can  crack such  a password in one minute.
  2. Never  use personal information in passwords!  Your name, surname, telephone number, date of birth, name of your  wife,  a pet nickname, etc. should  not   be  specified  here.
  3. Never  use short passwords. No matter how complex a few characters of your  password are,  it will not be difficult to  hack it if  it is short.
  4. Never  use monosyllabic words.  Everything  you  can find in any English dictionary should not be your password. For example: love, mercedes, friendship, samsung, super_girls, dog, cat  etc. won't obviously fit. No words, bearing some meaning at least.
  5. Do  not use the same password everywhere. It is better to use two or  three different ones.
  6. Do  not keep your password in a folder of your computer. The best option  would be if you remember it or write itdown on a piece of paper. 
  7. Do  not use curse words in the password - they are easy to find for  a hacker.
      

Never let your computer be hacked just because of your weak passwords!

Mini Password Buffer Overflow Tut








 Password Form Buffer Overflows

  • In this Lesson we will be learning how to do a Login/Password Form  Buffer Overflow. This is a very basic version of a Buffer Overflow but  just as effective. Basically what is happening here is that Password  Forms usually have a limit on the number of Characters they are aloud  input, but we will bypass this limit overloading the login and getting  access to the Server!  

    •  
  • To do this we will need a tool call WebDeveloper for Firefox, which you can download here  

    •  
  • This is a very simple Hack so it only works on some Basic  Authentication Logins, but its good know for the future if you find any!   So on firefox Go Tools>Web Developer>Forms>Remove Maximum  Lengths Now type in a massively long code eg "aaaaaaaaaaaaaaaaaaaaaaaaa"  and so on, and it should come up with an error page either showing the  encrypted passwords, or clear text passwords on the server!    

    •  
 

Congratulations now you know a simple Form Buffer Overflow!
