How passwords are cracked

Automated dictionary programs are one of many tools frequently used to crack passwords.

A hacker will launch a dictionary attack by passing every word from a dictionary (which can contain foreign languages and commonly passwords, in addition to the entire English language) to a login program hoping that a word will eventually match the correct password. 

Even viruses and worms will attempt to guess passwords.
