Although many people do not want their password to be known by others, but often they eventually choose the password can be cracked, like "12345". Although this type of password is easy for the user to remember, it is also easy for attackers to crack, especially in projects with an automated list of common choices. Joseph Bonneau, a computer scientist at Cambridge University, recently published an analysis of nearly 70 million Yahoo user passwords.
A table in the report shows a scale chart of how many user passwords have been cracked after 1000 guesses. It is estimated that when the amateur linguists see this form, they will be very funny to sigh: "How the Chinese People's password set so confidential, and others Indonesia is so bad!"
Another particularly interesting phenomenon is that when you use a generic dictionary to crack a password, there is little difference in the rate of cracking. As can be seen from the figure, when using Chinese dictionary to crack the Chinese account password, the crack ratio is about 4%, and when using the automatic point to crack, this ratio will drop to 2.9%. It seems that every language user has a similar preference.
