Brute Force Password Cracker Free For Windows 7

The brute force attack is still one of the most popular password-cracking methods. Nevertheless, it is not just for password cracking. Brute force attacks can also be used to discover hidden pages and content in a web application. This attack is basically “a hit and try” until you succeed. This attack sometimes takes longer, but its success rate is higher.

ROM BIOS or commonly known as BIOS, is an integral part of a computer. Whenever we turn on the computer, initially, it shows the memory capacity.Suddenly, the light of the NUM lock glows, and there is a beep sound at the end, after which we see the familiar Windows Logo.

However, if the password is something simpler, they will probably be able to crack it. John The Ripper – Another free password cracker that works on Windows, Linux and Macs, so it’s useful for any Mac or Linux user who wants to recovery a password. Pretty easy to use and comes with good instructions, so most people can follow along. Ophcrack is another brute-forcing tool specially used for cracking Windows passwords. It cracks Windows passwords by using LM hashes through rainbow tables. It is a free and open-source tool. In most cases, it can crack a Windows password in a few minutes.

In this article, I will try to explain brute force attacks and popular tools used in different scenarios for performing brute force attacks to get desired results.

What is a brute force attack?

A brute force attack when an attacker uses a set of predefined values to attack a target and analyze the response until he succeeds. Success depends on the set of predefined values. If it is larger, it will take more time, but there is a better probability of success.

The most common and easiest to understand example of the brute force attack is the dictionary attack to crack passwords. In this, the attacker uses a password dictionary that contains millions of words that can be used as a password. The attacker tries these passwords one by one for authentication. If this dictionary contains the correct password, the attacker will succeed.

In a traditional brute force attack, the attacker just tries the combination of letters and numbers to generate a password sequentially. However, this traditional technique will take longer when the password is long enough. These attacks can take several minutes to several hours or several years, depending on the system used and length of password.

To prevent password cracking from brute force attacks, one should always use long and complex passwords. This makes it hard for attackers to guess the password, and brute force attacks will take too much time. Account lockout is another way to prevent the attacker from performing brute force attacks on web applications. However, for offline software, things are not as easy to secure.

Similarly, for discovering hidden pages, the attacker tries to guess the name of the page, sends requests and sees the response. If the page does not exist, it will show a 404 response; on a success, the response will be 200. In this way, it can find hidden pages on any website.

Brute force is also used to crack the hash and guess a password from a given hash. In this, the hash is generated from random passwords and then this hash is matched with a target hash until the attacker finds the correct one. Therefore, the higher the type of encryption (64-bit, 128-bit or 256-bit encryption) used to encrypt the password, the longer it can take to break.

Reverse brute force attack

A reverse brute force attack is another term that is associated with password cracking. It takes a reverse approach in password cracking. In this, the attacker tries one password against multiple usernames. Imagine if you know a password but do not have any idea of the usernames. In this case, you can try the same password and guess the different usernames until you find the working combination.

Now, you know that a brute-forcing attack is mainly used for password cracking. You can use it in any software, any website or any protocol which does not block requests after a few invalid trials. In this post, I am going to add a few brute force password-cracking tools for different protocols.

Popular tools for brute force attacks

Aircrack-ng

For

I am sure you already know about the Aircrack-ng tool. This is a popular brute force wifi password cracking tool available for free. I also mentioned this tool in our older post on most popular password-cracking tools. This tool comes with WEP/WPA/WPA2-PSK cracker and analysis tools to perform attacks on Wi-Fi 802.11. Aircrack-ng can be used for any NIC which supports raw monitoring mode.

It basically performs dictionary attacks against a wireless network to guess the password. As you already know, the success of the attack depends on the dictionary of passwords. The better and more effective the password dictionary is, the more likely it is that it will crack the password.

It is available for Windows and Linux platforms. It has also been ported to run on iOS and Android platforms. You can try it on given platforms to see how this tool can be used for brute force wifi password cracking.

Brute

John the Ripper

John the Ripper is another awesome tool that does not need any introduction. It has been a favorite choice for performing brute force attacks for a long time. This free password-cracking software was initially developed for Unix systems. Later, developers released it for various other platforms. Now, it supports fifteen different platforms including Unix, Windows, DOS, BeOS and OpenVMS.

You can use this either to identify weak passwords or to crack passwords for breaking authentication.

This tool is very popular and combines various password-cracking features. It can automatically detect the type of hashing used in a password. Therefore, you can also run it against encrypted password storage.

Basically, it can perform brute force attacks with all possible passwords by combining text and numbers. However, you can also use it with a dictionary of passwords to perform dictionary attacks.

Rainbow Crack

Rainbow Crack is also a popular brute-forcing tool used for password cracking. It generates rainbow tables for using while performing the attack. In this way, it is different from other conventional brute-forcing tools. Rainbow tables are pre-computed. It helps in reducing the time in performing the attack.

The good thing is that there are various organizations which have already published the pre-computer rainbow tables for all internet users. To save time, you can download those rainbow tables and use them in your attacks.

This tool is still in active development. It is available for both Windows and Linux and supports all latest versions of these platforms.

Conclusion

These are a few popular brute-forcing tools for password cracking. There are various other tools are also available which perform brute force on different kinds of authentication. If I just give an example of a few small tools, you will see most of the PDF-cracking and ZIP-cracking tools use the same brute force methods to perform attacks and crack passwords. There are many such tools available for free or paid.

Brute-forcing is the best password-cracking method. The success of the attack depends on various factors. However, factors that affect most are password length and combination of characters, letters and special characters. This is why when we talk about strong passwords, we usually suggest that users have long passwords with a combination of lower-case letters, capital letters, numbers and special characters. It does not make brute-forcing impossible but it does make it difficult. Therefore, it will take a longer time to reach to the password by brute-forcing.

Almost all hash-cracking algorithms use the brute force to hit and try. This attack is best when you have offline access to data. In that case, it makes it easy to crack and takes less time.

Brute force password cracking is also very important in computer security. It is used to check the weak passwords used in the system, network or application.

The best way to prevent brute force attacks is to limit invalid logins. In this way, attacks can only hit and try passwords only for limited times. This is why web-based services start showing captchas if you hit the wrong passwords three times or they will block your IP address.
