What is Brute Force - Password cracking ?


Hello , The topic of this article is "Brute Force".In this article i will explain the meaning of bruteforce and will provide some top Brute force softwares to download.Lets Strat....

 Brute force (also known as brute force cracking) is a trial and error method used by application programs to decode encrypted data such as passwords or Data Encryption Standard (DES) keys, through exhaustive effort (using brute force) rather than employing intellectual strategies. Just as a criminal might break into, or "crack" a safe by trying many possible combinations, a brute force cracking application proceeds through all possible combinations of legal characters in sequence. Brute force is considered to be an infallible, although time-consuming, approach.

Crackers are sometimes used in an organization to test network security, although their more common use is for malicious attacks. Some variations, such as L0phtcrack from L0pht Heavy Industries, start by making assumptions, based on knowledge of common or organization-centered practices and then apply brute force to crack the rest of the data. L0phtcrack uses brute force to crack Windows NT passwords from a workstation. PC Magazine reported that a system administrator who used the program from a Windows 95 terminal with no administrative privileges, was able to uncover 85 percent of office passwords within twenty minutes.

You must have seen in movies how a hacker cracks a password. He take out a small device from his pocket. Connect it to the locker or whatever he wants to crack and then lots of digits and alphabets are shuffled on the device’s screen and in a matter of minutes (and sometimes in seconds), the thing is unlocked. Pretty Impressive but it doesn’t happen that way. Basically a online system (by online system i means a system which requires you to log in to get access) can’t be hacked like that. Even a password stored in a offline file can’t be hacked so easily.

Lets take it as easy as it can get. You want to access a file which is password protected. You create a program that tries every possible combination of alphabets and numbers and then feed it to the file if its the right one. This procedure is repeated till the right combination is accepted by the file. This is what we call as a attack. And this very procedure of trying possible combinations is called Brute Force Attack.

Now executing such a program which is required to provide every possible combination requires a very good computing power. The time that it consumes in breaking a password depends on the length of password and the processor speed. Faster the processor, shorter the time it takes to crack the password. Think it would be easy if you have a dual core or quad core, Think again. On Desktop PCs it can take days to crack a password.

Memory Space Trade Off – It is a situation in which time taken for processing can be reduced at the cost of space and vice versa. To make it very clear, lets see this again with the help of an example. In the previous example, we can process the different combination before hand and then store them in a file. And when you need to break a password, combinations are retrieved from that file and this lessens the load on the processor. The only time consumption in this case is the retrieval of data from that file. This file is what is known as a Rainbow Table. It can break passwords in a few minutes and in even a few seconds depending how strong is the password. It can be obtained from the World Wide Web but beware of its size. Its size is in GBs.

Now even if a hacker has the best of hardware, he can’t hack that easily. Why? Ever entered a password wrong multiple times? It requires you to enter the image to confirm that you are a human and it is not a account and even if that fails (yes there are algorithms that can read the text behind the image), the user is forbidden to enter the password for a fixed amount of time. So, there is no way in hell that a hacker can hack by Brute force or even with the help of rainbow tables. But it surely gets the job done for offline files.

If I write more here in a single post, it would be difficult for many of us to analyze the information. So, more in coming ICA articles.But i am providing some most top used Brute force softwares,you can download them and use for testing purpose...

How to Hack Softwares to use them Forever ?



Hi, I am back today with a most usefull article..Hope all of you will Like It ! Here i will show you that "How to Hack Softwares to use them Forever ?" . That really a useful article,because in our daily life we need thousand of softwares today,which of most are highly paid..So how to use them Freely for whole Like ??

Most of us are familiar with many softwares that run only for a specified period of time in the trial mode.Once the trial period is expired these softwares stop functioning and demand for a purchase.But there is a way to run the softwares and make them function beyond the trial period. Isn’t this interesting?

Before I tell you how to hack the software and make it run in the trial mode forever, we have to understand the functioning of these softwares.I’ll try to explain this in brief.Because Purpose if ICA is 1st to clear your basics.So,When these softwares are installed for the first time, they make an entry into the Windows Registry with the details such as Installed Date and Time, installed path etc.After installation every time you run the software, it compares the current system date and time with the installed date and time.So, with this it can make out whether the trial period is expired or not.

So with this being the case, just manually changing the system date to an earlier date will not solve the problem.For this purpose there is a small Tool known as RunAsDate.

RunAsDate is a small utility that allows you to run a program in the date and time that you specify. This utility doesn’t change the current system date, but it only injects the date/time that you specify into the desired application.


Intercepts the kernel API calls that returns the current date and time (GetSystemTime, GetLocalTime, GetSystemTimeAsFileTime), and replaces the current date/time with the date/time that you specify.It works with Windows 2000, XP, 2003 and Vista.

NOTE: FOLLOW THESE TIPS CAREFULLY
You have to follow these tips carefully to successfully hack a software and make it run in it’s trial mode forever.
1. Note down the date and time, when you install the software for the first time.
2. Once the trial period expires, you must always run the software using RunAsDate .
3. After the trial period is expired, do not run the software(program) directly.If you run the software directly even once, this hack may no longer work.
4. It is better and safe to inject the date of the last day in the trial period.

For example, if the trial period expires on oct 1 2009, always inject the date as sep 30 2009 in the RunAsDate.

Warning : AVG Antivirus reports that RunAsDate is infected with "Trojan horse Generic 10.Thk". This will not harm ur pc,warning is just bcoz this is a wondow registry hack tool !
