COMMON PASSWORD

Dictionary attack is everywhere! Attempt to guess passwords by using well-known words or phrases.

Since most passwords are chosen by users, it stands to reason that most passwords are or contain common words. There are a little over a million words in the English not only English it depend on population of the languages, while there are 308,915,776 possible combinations of 7 letters. Because human can remember or memorize 7 numbers!

Most attackers will take this into account when attempting to intrude on your system, and make use of word lists and upgrade their list as well if they couldn’t break any walls!

Then brute-force attack occurs when an attacker checks all possible passwords until the correct one is found. When attempting to guess passwords, this method is very fast when used to check short passwords, but is generally used in combination with dictionary attacks and common password lists for more efficient guesses at longer passwords.

Brute-force attacks are generally performed using scripts or dedicated tools, which can generate hundreds of HTTP requests per second. Even if no passwords are guessed correctly, use of such a tool may constitute a denial of service (DOS) attack.

Users are creatures of habit, which means they tend to choose obvious passwords and re-use them over multiple sites. Therefore I always suggested to change your password constantly, and don’t try to use the common passwords.
