Reality about Password Hacking softwares

You might have heard about some paid password hacking softwares which claim to hack a password on entering the email account.But in reality all those softwares are fake.If you believe what they say then you are just wasting your time and money.These all softwares are fake.If there exists such a software, will there be any security on web. And all expert engineers at Google, Yahoo and other services are not mad. They are all engaged in ensuring security of their customers ie email account owners. So, no such software exists.
So stop wasting your time and money on these foolish softwares and services and learn real Ethical Hacking methods which hackers use to access email accounts.

How to hack remote computer using IP Address

Literally, hacking is accessing something or somebody in internetwithout their permission or interest. While, speaking in summary, hacking is very easy job, it is like instead of using front door, finding the hidden door of a house and hijacking the precious things. Among all the hacking, hacking via IP address is one of the most common yet powerful beginning.

You may want to hack the website and put your advertisement there or grab some database information In this type of hacking, you are playing with the web server’s computer instead of the administrator’s computer. Because, www.website.com is hosted in separate web server rather than personal computer.

Another can be accessing your friend’s computer from your home. Again this is IP based and this is possible only when your friend’s computer is online. If it is off or not connected to internet then remote IP hacking is totally impossible.

Well, both of the hacking has the same process. Let’s summarize what we must do.

1. Confirm the website or a computer you want to hack.
2. Find or trace their IP address.
3. Make sure that IP address is online
4. Scan for open ports
5. Check for venerable ports
6. access through the port
7. Brute-force username and password

Now let me describe in brief in merely basic steps that a child can understand it.

First, getting the IP address of victim.

To get the IP address of the victim website, ping for it in command prompt.

For example,

ping www.google.com

will fetch the IP address of Google.com

This is how we can get the IP address of the victims website.

How about your friend’s PC? You can’t do www.yourfirend’sname.com, can you? Finding your friend’s IP address is little tough job, and tougher it is if he has dynamic IP address that keeps changing.

One of the widely used method to detect IP address of your friend is by chatting with him.

Now you got the IP address right? Is it online?

To know the online status just ping the IP address, if it is online it will reply.

If the IP address is online, scan for the open ports. Open ports are like closed door without locks, you can go inside and outside easily.

Use Advanced Port Scanner to scan all open and venerable ports.

Now you’ve IP address and open port address of the victim, you can now use telnet to try to access them. Make sure that you’ve telnet enabled in your computer or install it from Control panel > Add remove programs > add windows components.

Now open command prompt and use telnet command to access to the IP address. Use following syntax for connection.

telnet [IP address] [Port]

You’ll be asked to input login information.

If you can guess the informations easily then it’s OK. Or you can use some brute-forcing tools like this one.

Hack Password of any Operating System-windows,linux and mac with Ophcrack

What is ophcrack? 

Ophcrack 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.

You can download OphCrack from the following link:

http://ophcrack.sourceforge.net

FEATURES

 Runs on Windows, Linux/Unix, Mac OS X, ...
 Cracks LM and NTLM hashes.
 Free tables available for Windows XP and Vista.
 Brute-force module for simple passwords.
 Audit mode and CSV export.
 Real-time graphs to analyze the passwords.
 LiveCD available to simplify the cracking.
 Loads hashes from encrypted SAM recovered from a Windows partition, Vista included.
 Free and open source software (GPL).

OPHCRACK PROCEDURES

First step 

This step is optional but will speed up the cracking process. 

Run ophcrack and set the number of threads under the Preferences tab to the number of cores of the computer running ophcrack plus one.For example, for an old processor set the number of threads to 2, for a Core 2 Duo to 3 and for a Core 2 Quad to 5. If you change this value, you have to exit ophcrack and to restart it in order to save the change. If you don't exit and restart, the new number of threads will not be taken into account by the program. 

Second step 

This step is mandatory. 

Load hashes using the Load button. You can either enter the hash manually (Single hash option), import a text file containing hashes you created with pwdump, fgdump or similar third party tools (PWDUMP file option), extract the hashes from the SYSTEM and SAM files (Encrypted SAM option), dump the SAM from the computer ophcrack is running on (Local SAM option) or dump the SAM from a remote computer (Remote SAM option). 

For the Encrypted SAM option, the SAM is located under the Windows system32/config directory and can only be accessed for a Windows partition that is NOT running. For the Local SAM and Remote SAM options, you MUST logged in with the administrator rights on the computer you want to dump the SAM. 

Third step 

This step is optional but will speed up the cracking process. 

Delete with the Delete button every user account you are not interested in (for exemple the Guest account). You can use the Ctrl key to make multiple selection. Ctrl-a will select every loaded hash. 

Keep in mind that the time needed to crack password hashes with rainbow tables is proportional to the number of hashes loaded. With a brute force attack the cracking time is NOT dependant on the number of unsalted hashes loaded. That's why it's advisable to remove any unnecessary user account with the Delete button. 

Fourth step 

This step is mandatory. 

Install (Tables button), enable (green and yellow buttons) and sort wisely (up and down arrows) the rainbow tables your are going to use. Keep in mind that storing the rainbow tables on a fast medium like a hard disk will significantly speed up the cracking process. 

Here are a few guidelines : 

If you want to crack LM hashes as found on Windows XP by default (the LM Hash column is never empty on the ophcrack main window), first install and enable either the XP free small (if you have less than 512MB of free RAM) or the XP free fast (if you have more than 512MB of free RAM). Do NOT enable both of them since this is generally useless and will slow down the cracking process. Then install and enable the Vista free tables set. Finally install and enable the other XP rainbow tables you may have (XP special, XP german) and Vista one (Vista special). Sort the rainbow tables with the up and down arrows the following way : first the XP free then the Vista free then the XP special after that the Vista special and finally the XP german. 
If you want to crack NT hashes as found on Windows Vista by default (the LM Hash column is always empty on the ophcrack main window), first install and enable the Vista free tables set. Then install and enable the Vista special tables set. Disable every other XP tables sets since they are useless and slow down the cracking process. Sort the enabled rainbow tables with the up and down arrows the following way : first the Vista free then the Vista special. 
If you want to crack a mix of LM and NT enabled hashes (some accounts have their LM column empty, others have both the LM and NT columns filled with hashes) proceed the same way as "If you want to crack LM enabled hashes". 

Fifth step 

This step is mandatory. 

Click on the Crack button to start the cracking process. You'll see the progress of the cracking process in the bottom boxes of the ophcrack window. When a password is found, it will be displayed in the NT Pwd field. You can then save the results of a cracking session at any time with the Save button. 

HOW TO USE IN DIFFERENT OPERATING SYSTEMS

Windows

Simply download the Ophcrack ISO and burn it to a CD (or load it onto a USB drive via UNetbootin). Insert the CD into a machine you would like to gain access to, then press and hold the power button until the computer shuts down. Turn the computer back on and enter BIOS at startup. Change the boot sequence to CD before HDD, then save and exit.

The computer will restart and Ophcrack will be loaded. Sit back and watch as it does all the work for your. Write down the password it gives you, remove the disc, restart the computer, and log in as if it were you own machine.

Linux

To change the password, turn on the computer and press the ESC key when GRUB appears. Scroll down and highlight ‘Recovery Mode’ and press the ‘B’ key; this will cause you to enter ‘Single User Mode’.

You’re now at the prompt, and logged in as ‘root’ by default. Type ‘passwd’ and then choose a new password. This will change the root password to whatever you enter. If you’re interested in only gaining access to a single account on the system, however, then type ‘passwd username’ replacing ‘username’ with the login name for the account you would like to alter the password for.

Mac

The easiest method would be to use Ophcrack on this also as it works with Mac and Linux in addition to Windows. However, there are other methods that can be used, as demonstrated below.

If the Mac runs OS X 10.4, then you only need the installation CD. Insert it into the computer, reboot. When it starts up, select UTILITIES > RESET PASSWORD. Choose a new password and then use that to log in.

If the Mac runs OS X 10.5, restart the computer and press COMMAND + S. When at the prompt, type:

fsck -fy

mount -uw /

launchctl load /System/Library/LaunchDaemons/com.apple.DirectoryServices.plist

dscl . -passwd /Users/UserName newpassword

Unlock Password Protected PDF Files

In this article I am going to share a nice trick to unlock or remove password protected PDF files.You may seen some PDF files downloaded from internet or from any other source with password protected.That is it will ask for password everytime when it is opened.It may be annoying for you to enter the passwords each time or to open the PDF files for which you dont even know its password.So here I am going to introduce a tool called PDF Password Remover. ThisTool is a PDF decryption tool developed by PDF Technologies that can be used to decrypt password protected PDF files.PDF Password Remover Tool can remove owner password from PDF files. PDF files with the owner password set would prevent viewers from editing, selecting text, printing and otherwise changing any of the pdf properties such as form fields etc.
