You can learn to hack passwords of almost everyone and everything, its easy!!
Including FACEBOOK, INSTAGRAM, TWITTER, GMAIL, COMPUTER PASSWORD, Wi-Fi, bla bla bla.
Cracking passwords these days has become really an easy job with the help of enormously strong tools and tricks, I'll demonstrate you some I’ve been using. Here we will see cracking passwords of PC and accounts by software tools as well as hardware tools.
Password Storage
In general, passwords are not stored in clear text. As a rule, passwords are stored as hashes. Hashes are one-way encryption that are unique for a given input. These systems very often use MD5 or SHA1 to hash the passwords.
Hacking a Computer Password
In Windows OS
- password is saved in SAM file
In Linux
- Linux stores them in the /etc/shadow file
Crack
- use a service or file that has root/sysadmin privileges to grab the password file.
- DLL injection with samdump.dll in Windows.

Types of Attacks
Dictionary
A dictionary attack is the simplest and fastest password cracking attack. To put it simply, it just runs through a dictionary of words trying each one of them to see if they work.
Rainbow Table
Most modern systems now store passwords in a hash. This means that even if you can get to the area or file that stores the password, what you get is an encrypted password. One approach to cracking this encryption is to take dictionary file and hash each word and compare it to the hashed password.
Brute Force
Brute force is the most time consuming approach to password cracking. It should always be your last resort. Brute force password cracking attempts all possibilities of all the letters, number, special characters that might be combined for a password and attempts them. As you might expect, the more computing horsepower you have, the more successful you will be with this approach.
Hybrid
A hybrid password attack is one that uses a combination of dictionary words with special characters, numbers, etc. Often these hybrid attacks use a combination of dictionary words with numbers appending and prepending them, and replacing letters with numbers and special characters. For instance, a dictionary attack would look for the word "password", but a hybrid attack might look for "p@$$w0rd123".
Commonly Used Passwords
As much as we think each of us is unique, we do show some common patterns of behavior within our species. One of those patterns is the words we choose for passwords. There are number of wordlists that have been compiled of common passwords.
Password Cracking Strategy
Many newbies, when they start cracking passwords, simply choose a tool and word list and then turn them loose. They are often disappointed with the results. Expert password crackers have a strategy. They don't expect to be able to crack every password, but with a well-developed strategy, they can crack most passwords in a very short amount of time.
The key to develop a successful strategy of password cracking is to use multiple iterations, going after the easiest passwords with the first iteration to the most difficult passwords using different techniques for each iteration.
NOW THIS IS WHAT EVERYONE IS LOOKING FOR(cracking online account passwords)
John
John the Ripper is probably the world's best known password cracking tool. It is strictly command line and strictly for Linux. Its lack of a GUI makes a bit more challenging to use, but it is also why it is such a fast password cracker.
One of the beauties of this tool is its built in default password cracking strategy. First, attempts a dictionary attack and if that fails, it then attempts to use combined dictionary words, then tries a hybrid attack of dictionary words with special characters and numbers and only if all those fail will it resort to a brute force.
Ophcrack
Ophcrack is a free rainbow table-based password cracking tool for Windows. It is among the most popular Windows password cracking tools (Cain and Abel is probably the most popular; see below), but can also be used on Linux and Mac systems.
It cracks LM and NTLM (Windows) hashes. For cracking Windows XP, Vista and Windows 7, you can download free rainbow tables. You can download Ophcrack on SourceForge.
Cain and Abel
Cain and Abel just might be the best known password cracking tool on the planet. Written strictly for Windows, it can crack numerous hash types, including NTLM, NTLMv2, MD5, wireless, Oracle, MySQL, SQL Server, SHA1, SHA2, Cisco, VoIP, and many others.
Cain and Abel can crack passwords using a dictionary attack, rainbow attack, and brute force. One of its better features is the ability to select the password length and character set when attempting a brute force attack. And besides being an excellent password cracking tool, it is also a great ARP poisoning and MiTM tool.
THC-Hydra
THC-HYDRA is probably the most widely used online hacking tool. It is capable of cracking web form authentication, and when used in conjunction with other tools such as Tamper Data, it can be a powerful and effective tool for cracking nearly every type of online password authentication mechanism.
HACKING WI-FI
Aircrack-Ng
In my humble opinion, aircrack-ng is undoubtedly the best all-around Wi-Fi hacking software available. It is capable of cracking both WEP and WPA2, and it is also capable of doing the following, among many other things.
- Creating a Soft AP
- creating an Evil Twin
- Creating a Rogue AP
- Conducting a DOS attack against a WI-FI AP
It is only available for Linux and requires a bit of a learning curve to master, but you will be richly rewarded for the time spent learning it. In addition, to be most effective you will need to use an aircrack-ng compatible wireless card, so check their extensive list before buying your card. You can find more info on aircrack-ng over in my WI-FI hacking series.
Aircrack-ng is built into BackTrack and Kali
Password Cracking Hardware
Botnet
Password cracking is simply a function of brute force computing power. What one machine can do in one hour, two machines can do in a half hour. This same principle applies to using a network machines. Imagine what you can do if you could access a network of one million machines!
Some of the botnets available around the globe are more than a million machines strong and are available for rent to crack passwords. If you have a password that might take one year to crack with your single CPU, a million-machine botnet can cut that time to approximately 1 millionth the time, or 30 seconds!
GPU
GPUs, or graphical processing units, are much more powerful and faster than CPU for rendering graphics on your computer and for cracking passwords. We have a few tools built into Kali that are specially designed for using GPUs to crack passwords, namely cudahashcat, oclhashcat, and pyrit. Look for coming tutorials on using these tools and the GPU on your high-end video card to accelerate your password cracking.
ASIC
In recent years, some devices have been developed specifically for hardware cracking. These application-specific devices can crack passwords faster than over 100 CPUs working symmetrically.
Black Arrow Software and Butterfly Labs, among others, are now selling these devices for prices up to $1500 .
