I;m sure most of the attacks weren't done by brute force (all possiblities). Though, it had to start somewhere and i think there could be 1 or 2 accs hijjaked with brute force. Here is advice how to be safe from it. Our real password consists of 9 numbers = 547861206
The brute-force tool is installed on a “Core 2 Extreme QX6600-2400 x4,Windows Vista home Premium” computer.This computer can check -38421.9 keys/second-.
Combinations = letter number to the power of password-length
Our number of letters is 10 because we can get numbers from 0 - 9.
Our password-length is 9,because our password consists of 9 numbers.
So : 10^9 = 1,000,000,000
1,000,000,000 / 38421.9
= 26,026.82 seconds
Our password is not safe!Hackers can get it in 26 seconds.
lower case letters = 26 different letters
capital letters = 26 different letters
numbers = 10 different letters
Now,we use a password which consists of 9 letters(numbers + lower case letters)
Our password = jhrz86qsd
36^9 = 1.015599567 x 10^14
1.015599567 x 10^14 / 38421.9 = 2,643,283,041 seconds
= 734245.3 hours = 30593.55 days
This password is safe.
also remeber about NOT using standad pws like password, pw, qwerty, 1234 and so on.
