The most common password attack is the dictionary one, isn’t it ?
Unfortunately there is enormous amount of users out there who use weak passwords, or even worse the same password as the username. Common pass phrases are:
- family names
- wife/husband names
- phone numbers
- street name
CUPP is a tool which generates a text file containing most of these common passwords and their variations such as password, p@ssword, p@ssw0rd, etc.
It is a python script therefore it is very easy to alter according to your needs and requirements.
