CUPP(Common User Passwords Profiler) is tool to generate wordlist from common user profiler. The most common form of authentication is the combination of a username and a password or passphrase. If both match values stored within a locally stored table, the user is authenticated for a connection. Password strength is a measure of the difficulty involved in guessing or breaking the password through cryptographic techniques or library-based automated testing of alternate values.
A weak password can also be one that is easily guessed by someone profiling the user, such as a birthday, nickname, address, name of a pet or relative,or a common word such as God, love, money or password. From a social engineering you can obtain information to use with the CUPP, this way the tool can create a very effective dictionary for brute force attacks or dictionary attacks.
