Analysis of 32 Million Breached Passwords
An anonymous reader writes “Imperva released a study analyzing 32 million passwords exposed in the Rockyou.com breach. The data provides a unique glimpse into the way that users select passwords and an opportunity to evaluate the true strength of these as a security mechanism. In the past, password studies have focused mostly on surveys. Never before has there been such a high volume of real-world passwords to examine.” Most interesting to me was that in the sample, less than 4% used any non alpha-numerics in their #$#%’ing passwords.
