Recently, Imperva released a study (pdf) of the passwords extracted from the December 2009 RockYou security breach that resulted in the compromise of over 32 million user accounts. This study examined some statistics of the passwords retrieved, including the number and variation of characters use to construct them. The results were pretty bad. Here are the highlights: -30% of users had passwords made up of 6 characters or less.

Even a password that is longer than 6 characters is weakened if it has a small character set distribution. On the surface, these[…]

The study is available for download at http://www.encryptionreports.com/ after giving away some personal details. The “Fifth Annual U.S. Cost of Data Breach Study,” funded in part by encryption vendor PGP Corp., determines the annual cost of the breach by establishing a company’s cost of lost business as a result of an incident; expenses incurred by notifying individuals and authorities of a breach; costs associated with legal fees and consulting firms and new investments made in technology and employee education.

The report is sure to be a good read. We linked last year’s report, and this year’s report has some improvements–it is based on more data was collected more often, and goes into a lot more detail than the previous report. 285 million[…]
