How to Crack Windows Administrator Passwords




Some times it necessary to know admin passwords in schools ,collages to log in with admin privileges to do various things

There are many way to crack passwords. But in this tutorial I will explain a very basic method using a single tool to crack windows password . This might come handy in places like schools ,collages where you cant use your live Linux cds , usb ..etc because your being watched


Things we need :


1. Pwdump or Fgdump to extract password hashes


In this tutorial I will be using Pwdump


Extracting Password hashes :-


1. Open My computer and go to C:\Windows\system32 . now place the Pwdump file which we download earlier


2. Now open command prompt and navigate to C:\Windows\system32 \Pwdump


Using cd command and click enter


Example :-


Cd C:\Windows\system32 \Pwdump




3. Now you can see a list of Pwdump commands as shown

4. Now enter pwdump - localhost >>“ destination of output file “ (for 32 computers) and pwdump -x localhost >> “destination out put file “(for 64 bit computers )


Example :-

Cd C:\Windows\system32 \Pwdump localhost >> C:\hashes.txt

Cd C:\Windows\system32 \Pwdump -x localhost >> C:\hashes.txt


5. Now open  the Out put  file  you can see the names of the different  users with password hashes Now copy the hashes  corresponding to the admin account

Cracking The Hashes 
Considering that we are in school/collage were we cant use tools to crack passwords so as an alternative we are using online password cracking sites

1. Go to online password cracking sites like www.cracker.offensive-security.com ,www.onlinehashcrack.com and paste the hash select hash type as LM and click decode

2.By this way we are able to crack windows password using a single tool

Note:- If your not able to crack password hashes online use tools like john the ripper to crack password hashes . You can even copy the hashes and decoded it in your house


Cracking FTP Passwords Using Dictionary Attacks

What is a Dictionary Attack ?

In layman language, Dictionary attack means using a tool that picks passwords from a wordlist and tries them one by one until one works

How to make a wordlist ?

A wordlist can consist of all possible combinations ofletter,numbers,special characters. It can have some common or default passwords. You candownload the wordlist generators or google the wordlists for bruteforcing and configure them according to yourself.

How fruitful attack can be ?

If we are try all possible combinations of letter,numbers,special characters, theoretically chances of success are 100%. But practically it is not possible to try every combinationbecause it can take a lot of time. This attack just depends on the time you give,processing power and ofcourse your luck.

Tool I will be using ?
  
  • THC Hydra

    Step 1 

    Download THC Hydra from here 

    Step 2 

    (a) Make a usename wordlist consisting of some common usernames like this


    (b) Get a wordlist of passwords
    (c) Copy both wordlists to your hydra folder

    Step 3

    (a)Open the command prompt and change directory to your hydra folder using cd command.


    (b) Type "hydra" without quotes and it will show you the options to use.



    (c) Now to start attak,

    Type "hydra -L userslist.txt -P passlist.txt xxx.xxx.xxx.xxx ftp" and press enter

    where userslist.txt is the list of usernames, passlist.txt is the list of passwords andxxx.xxx.xxx.xxx is the IP address of target, Now it will start cracking

    To use a single username instead of wordlist , Replace capital L with small l , like this

    Type "hydra -l username -P passlist.txt xxx.xxx.xxx.xxx ftp"

    Note : Ftp port must be open.

    Warning: I highly recommend you to use a chain of proxies to spoof your identity because proper logs of user's IP addresses who try to connect to ftp server is made on the server. Here is an example of the same. 



    Countermeasures to protect yourself from this attack:

    1. Use strong passwords
    2. Enable Autoban of IPs or anyother option like this.

    Brute force Password Cracking explained


    Brute force is the best hacking method to an email account  as chances of getting password is very high.The methods is very simple . But this method is cumbersome. Still most hacking software use this method due to high success rate .

    This is how you do it. All that you need is the username and findout what is the max password length the software/site allows and also the minimum. say the minimum is 6 and max is 8. You have to start trying out all the combination.First all the six letter combos then seven then 8

    aaaaaa

    aaaaab

    aaaaac

    aaaaab

    .

    .

    abaaaa

    .

    .

    azzzzz

    baaaaa

    .

    ..

    zzzzzz


    Now once you do for 6 repeat the same for 7 and then for 8 . You will surely crack it.But the no of combos you need to try is very high.So in most cases you cannot use it but designed software do the job in few minutes. Check crack passwords section for such software's to crack your software/site. This is best used to recover passwords of mobile phone . If use them for hacking,you guys just remember to use strong passwords both upper,lower case and number too to make a strong password usually not below that 9 letter and minizme the chances of getting your account hacked

    Here are the two most popular and well known Brute forcers
    1.Brutus aet2                 2.Munga Brute force
