The Original methods of Hacking Passwords Revealed

Most passwords can be cracked by using Hashing, Guessing, Using Default passwords, Brute Force and Phishing. However, we can see many shareware products that costs near 100$ and they guarantees to hack account, The important thing is that

1) Hashing :- hashing will refer to the one way function (which may be either an encryption function or cryptographic hash) employed as a hash and its output as a hashed password.

If a system uses a reversible function to obscure stored passwords, exploiting that weakness can recover even 'well-chosen' passwords.

 For example, LM hash that Microsoft Windows uses by default to store user passwords which have less than 15 characters. 

The LM hash breaks the password into two 7-character fields which are then hashed separately, allowing each half to be attacked separately. 

2) Guessing :- Many passwords can be guessed either by humans or by sophisticated cracking programs armed with dictionaries (dictionary attack) and the user's personal information. 

Actually, many users choose weak passwords, usually one related to themselves in some way. Repeated research over some 40 years has demonstrated that around 40% of user-chosen passwords are readily guessable by programs. Examples of insecure choices include:

In one survey of MySpace passwords which had been phished, 3.8% of passwords were a single word found in a dictionary, and another 12 percent were a word plus a final digit; two-thirds of the time that digit was.

3) Default Passwords :- A moderately high number of local and online applications have inbuilt default passwords that have been configured by programmers during development stages of software. There are lots of applications running on the internet on which default passwords are enabled. So, it is quite easy for an attacker to enter default password and gain access to sensitive information. A list which containing default passwords of some of the most popular applications is available on the internet. Always disable or change the application's (both online and offline) default username-password pairs.

4) Brute Force :- If all other techniques failed, then attackers uses brute force password cracking technique. Here an automatic tool is used which tries all possible combinations of available keys on the keyboard. As soon as correct password is reached it displays on the screen.This techniques takes extremely long time to complete, but password will surely cracked. Long is the password, large is the time taken to brute force it.

5) Phishing :- This is the most effective, Most popular and easily executable password cracking technique which is generally used to crack the passwords of e-mail accounts, and all those accounts where secret information or sensitive personal information is stored by user such as social networking websites, matrimonial websites, etc.

Phishing is a technique in which the attacker creates the fake login screen and send it to the victim, hoping that the victim gets fooled into entering the account username and password. As soon as victim click on "enter" or "login" login button this information reaches to the attacker using scripts or online form processors while the user(victim) is redirected to home page of e-mail service provider.

Note:Sometimes you will get emails which are demanding for your username-password, urging to be e-mail service provider. Dont reply for them. Most Email providers and Social networks will not ask like this.

It is possible to try to obtain the passwords through other different methods, such as social engineering, wiretapping, keystroke logging, login spoofing, dumpster diving, phishing, shoulder surfing, timing attack, acoustic cryptanalysis, using a Trojan Horse or virus, identity management system attacks (such as abuse of Self-service password reset) and compromising host security.

However, cracking usually designates a guessing attack.
