How this attack works?
Mostly the password length in the internet world is '8'. Totally there are 26 characters in the alphabets. So adding uppercase and lowercase 26+26 = 52 characters. After adding numerical values the value will be 52 + 10 = 62. characters to try.
For 8 character combination
62 to the power of 8 = 2.1834011*10 to the power 14 possible combinations.
To try these combinations it would take 3.6 trillion minutes.
Thus it is not possible to do this with normal computers. Hence super computers are needed to do this kind of attacks.
But this kind of technologies are not available to common people. But password attacking attackers are not common people. They will collect computer resources from different sources like developing a powerfull computing engine etc..
