Brute Force with a Mask: Price on request
Brute force attacks or brute force cracking are when all possible characters that exist are tried until it hits on a combination that works. 100% success rate if correct mask (set of characters) is given.
For example, if you can remember that your password consisted of 8 or 9 characters, perhaps starts with “444,” and the remaining characters are lowercase letters (English alphabet), then that makes the search process a lot easier.
