Cracking passwords with more than 10 characters in a few hours?
Like Ricky Demer suggested, qeadzcwrsfxv is a common finger pattern (similar to something like asdfghjk).

The second example falls in the pattern of: Take dictionary word (besancon is the name of a city), uppercase the first letter and add a couple of digits after it (usually 123, 321, 007 or a year like 1998). Then a couple of rule-based alterations are tried: add a random letter, change a letter to a symbol (e.g. s => $) and so on.

A third way one of these passwords could have been cracked is by them being reused from another hack (e.g. the user used a variation of the password he used from linkedin).

In short, humans are very predictable in how they generate passwords.

A truly random password looks like this: T8vWdvLGhpRi9Gb. No discernable words or patterns. Numbers, lowercase and capital letters properly mixed together.  A password like this could only be broken by being reused on multiple websites or by being intercepted somehow.
