In cryptanalysis and computer security, password cracking is the process of guessing passwords [1] protecting a computer system. A common approach ( brute-force attack ) is to repeatedly try guesses for the password and to check them against an available cryptographic hash of the password. [ 2 ]
The Worst Passwords List is an annual list of the 25 most common passwords from each year as produced by internet security firm SplashData. [4] Since 2011, the firm has published the list based on data examined from millions of passwords leaked in data breaches, mostly in North America and Western Europe, over each year.
AOHell was the first of what would become thousands of programs designed for hackers created for use with AOL. In 1994, seventeen year old hacker Koceilah Rekouche, from Pittsburgh, PA, known online as "Da Chronic", [1] [2] used Visual Basic to create a toolkit that provided a new DLL for the AOL client, a credit card number generator, email bomber, IM bomber, and a basic set of instructions.

When password-guessing, this method is very fast when used to check all short passwords, but for longer passwords other methods such as the dictionary attack are used because a brute-force search takes too long. Longer passwords, passphrases and keys have more possible values, making them exponentially more difficult to crack than shorter ones ...

Script kiddies lack, or are only developing, programming skills sufficient to understand the effects and side effects of their actions. As a result, they leave significant traces which lead to their detection, or directly attack companies which have detection and countermeasures already in place, or in some cases, leave automatic crash ...
The easier a password is for the owner to remember generally means it will be easier for an attacker to guess. [12] However, passwords that are difficult to remember may also reduce the security of a system because (a) users might need to write down or electronically store the password, (b) users will need frequent password resets and (c) users are more likely to re-use the same password ...
Password strength is a measure of the effectiveness of a password against guessing or brute-force attacks. In its usual form, it estimates how many trials an attacker who does not have direct access to the password would need, on average, to guess it correctly. The strength of a password is a function of length, complexity, and unpredictability ...
