![]() This post describes some of the most commonly used password-cracking tools. Most password-cracking or password finder tools enable a hacker to perform any of these types of attacks. It starts by checking to see if a password can be cracked using a dictionary attack, then moves on to a brute-force attack if it is unsuccessful. Hybrid attack: A hybrid attack mixes these two techniques.While slow, a brute-force attack (trying all possible password combinations) guarantees that an attacker will crack the password eventually. Brute-force guessing attack: There are only so many potential passwords of a given length.Taking a list of words and adding a few permutations - like substituting $ for s - enables a password cracker to learn a lot of passwords very quickly. Dictionary attack: Most people use weak and common passwords.This can be accomplished in a few different ways: Password cracking refers to the process of extracting passwords from the associated password hash. ![]() Since hash functions are also deterministic (meaning that the same input produces the same output), comparing two password hashes (the stored one and the hash of the password provided by a user) is almost as good as comparing the real passwords. Hash functions are designed to be one-way, meaning that it is very difficult to determine the input that produces a given output. Instead, authentication systems store a password hash, which is the result of sending the password - and a random value called a salt - through a hash function. This would make it far too easy for a hacker or a malicious insider to gain access to all of the user accounts on the system. A well-designed password-based authentication system doesn’t store a user’s actual password.
