How to Use Ravan for Password Cracking?


In my previous article, i explained about the Ravan Tool.  Now let us see how to use the Ravan for cracking passwords.


Requriments:
Lot of Friends :
Ravan is Distributed password cracking method. So you will need lot of friends who have Pc with Internet connection. The speed of cracking will increase based on the number of pc contribute in the cracking.

How to use Ravan?

Step1:
  • Go to http://www.andlabs.org/tools/ravan.html
  • Enter the value of the hash that must be cracked
  • Enter the value of the salt, if it is not a salted hash then leave it blank
  • Enter the charset. Only these characters will be use in the brute force attack
  • Select the hashing algorithm (MD5, SHA1, SHA256, SHA512)
  • Select the position of the salt. (clear-text+salt or salt+clear-text)
  • Hit ‘Submit Hash’
Step 2:
 If hash is successfully submitted, it would return a URL.  Now you just need to send this URL to all your friends and ask them to click the start button.

    The main page manages the cracking so it must not be closed or the cracking would fail.

That is it. Once your friends click start they would be doing pieces of the work and submitting results back.


The main page would constantly monitor the progress of the cracking process and manage it across all the workers. You would be able to see the stats throughout the process, once the hash is cracked the clear-text value is displayed.

Ravan , JavaScript based Distributed Password cracking



You want to crack a hash but your system speed is low?! No need to worry..! Here is solution for you , "Distributed Password Cracking". Let me introduce a new tool called "Ravan" developed by LavaKumar.
About Ravan:
Ravan is a JavaScript based Distributed Computing system that can perform brute force attacks on salted hashes by distributing the task across several browsers. It makes use of HTML5 WebWorkers to start background JavaScript threads in the browsers of the workers, each worker computes a part of the hash cracking activity.
Ravan now supports MD5,SHA1,SHA256,SHA512 hashes.

How it works?
Ravan has three components:

Master:
The hash, salt, hashing algorithm, position of the salt (before or after salt) and the charset are submitted by the user. These are submitted to the web backend and it returns a ‘hash id’ which is unique to every submitted hash. It also supplies a ‘worker url’ specific to this hash that must be sent to potential workers.
Once the hash is submitted the master creates arrays of slots (each array contains 5 slots), this is submitted to the web backend. Each slot represents a small part of the keyspace, this is how the entire activity is broken down in to multiple tiny tasks. A single slot represents 1 million combinations.
The master constantly polls the web backend to check on the progress of the cracking process. As the existing list of slots is completed by the workers the master allots more slots. When a worker cracks the hash and returns the clear-text value the master confirm this and then signals all workers to stop cracking.

Web Backend:
The web backend acts as a proxy between the master and the workers. It does not perform any actual computation but validates the data submitted by both the parties and passes information between them.

Worker:
The worker performs the actual hard work of cracking the hashes. Each hash has a unique worker URL and this page explicitly asks for the user permission before the cracking process is started. Once the user accepts and clicks ‘Start’ the worker polls the web backend for available slots, the web backend returns an array of slots from its database. The worker cracks each slot and sends the result to the web backend. After completing all the slots it polls the web backend for more slots.

Here is the tool:

Large Password List: Free Download Dictionary File for Password Cracking


For password cracking, you can choose two different methods 1. Dictionary Attack 2. Brute Force Attack. The Dictionary attack is much faster when compared to Brute force attack.(There is another method named as "Rainbow table", it is similar to Dictionary attack).

In order to achieve success in dictionary attack, we need a large size of Password list.

Here is the list of 1,717,681 passwords(Free to download):
http://dazzlepod.com/site_media/txt/passwords.txt

If you didn't get success using the above password list, then you can get the UNIQPass dictionary file from dazzlepod.

UNIQPASS is large password list useful for use with John the Ripper (JtR) wordlist mode to translate even more hashes into cleartext passwords. While we have had good success rate with our standard password list passwords.txt (17.5MB), we realized the list can be made more useful and relevant if we include commonly used passwords from the recently leaked databases belonging to large websites. As a result, we have compiled millions of unique passwords into UNIQPASS.

UNIQPASS is available for purchase at only $4.99; see preview of UNIQPASS from these 2 million randomly selected passwords (18.9MB).

Get the UNIQPass Dictionary file from here:

How to crack or Reset BIOS Password? ~Cracking Tutorials


The BIOS software is built into the PC, and is the first code run by a PC when powered on ('boot firmware'). The primary function of the BIOS is to set up the hardware and load and start a boot loader. When the PC starts up, the first job for the BIOS is to initialize and identify system devices such as the video display card, keyboard and mouse, hard disk drive, optical disc drive and other hardware. The BIOS then locates software held on a peripheral device (designated as a 'boot device'), such as a hard disk or a CD/DVD, and loads and executes that software, giving it control of the PC. This process is known as booting, or booting up, which is short for bootstrapping.
Bios password is usually used to protect the user's BIOS settings on the computer. If you want to reset the password on the BIOS does not need to bother to connect bateray CMOSnya, with a little trick on the Dos you can reset the BIOS password on it in 2 ways:

1. Clear CMOS
This way I consider the most ancient and most easy to break down the password on the BIOS. The steps are easy, first open the casing cover computer CPU. Then find the bios battery that looks something like the battery just a little more big clock. After the meet and consider the area around the battery there is usually a jumper with 3 pins, 2 pins and 1 pin not connected.

Suppose the three pins with the code 1 - 2 - 3. Connector that connects the initial position usually is 2-3. To reset the bios do I move the position of the plug that connects pins 2-3 to position 1-2 for about 5 seconds. Then plug it back into the starting position (2-3). Try restarting the computer back on, secured the bios password is gone.

If the above looks complicated, is easy to clear cmos by unplugging the BIOS battery and then put it back. But with the consequences of removing the label is the warranty on the battery BIOS.

2. Through DOS

First out of the windows with me restart your computer, start the computer in MS-DOS mode, use the option "Command Prompt Only"

At c: prompt, type: DEBUG
press enter. You will see the sign (-) at the DEBUG prompt, then type:
o 70 2e
at the DEBUG prompt will be displayed as-o 70 2e.
press enter and type:
-O 71 ff
press enter, the last type:
Q
hit enter, then you will get out of the DEBUG prompt and return to the C:> prompt.
Now restart your COMPUTER, and see the results
