<P> A dictionary attack is based on trying all the strings in a pre-arranged listing , typically derived from a list of words such as in a dictionary ( hence the phrase dictionary attack ) . In contrast to a brute force attack , where a large proportion of the key space is searched systematically , a dictionary attack tries only those possibilities which are deemed most likely to succeed . Dictionary attacks often succeed because many people have a tendency to choose short passwords that are ordinary words or common passwords , or simple variants obtained , for example , by appending a digit or punctuation character . Dictionary attacks are relatively easy to defeat , e.g. by using a passphrase or otherwise choosing a password that is not a simple variant of a word found in any dictionary or listing of commonly used passwords . </P>
