How is a dictionary attack used to guess passwords?
A dictionary attack uses a preselected library of words and phrases to guess possible passwords. It operates under the assumption that users tend to pull from a basic list of passwords, such as “password,” “123abc” and “123456.” These lists include predictable patterns that can vary by region.

(Don’t worry, he didn’t steal them. The passwords were separated from their usernames.) Bonnea used the passwords to test possible hacking attempts. He found that using the 1,000 most common words in the dictionary an algorithm could correctly guess the passwords of up to 10% of the users.
Can a dictionary attack be performed offline or online?
A dictionary attack can be performed both online and offline. In an online attack, the attacker repeatedly tries to log in or gain access like any other user. This type of attack works better if the hacker has a list of likely passwords. If the attack takes too long, it might get noticed by a system administrator or the original user.
