Analysis of Sony Leak Shows Weak and Duplicate Passwords

By Jason Fitzpatrick on June 7th, 2011

Whenever there is a massive password leak it offers a treasure trove of data for security experts to analyze and the massive leak of Sony logins and passwords was no exception. Consider the analysis a guide in what not to do.

Troy Hunt did an analysis of the torrent of passwords released by the group that hacked Sony’s servers. He crunches the numbers on the logins for things like length, character selection, dictionary occurrence, and–rather interestingly–to the passwords from Gawker’s 2010 password breach. It turns out that a full 67% of users were using the exact same password on both networks (to put this in perspective the Gawker breach occured last year yet 67% of the Playstation Network users had not changed their password despite it being the exact login/password combo that had been leaked).

Hit up the link to read the full analysis and remember: use a different and strong password for every login! It’s highly probable that the users who recycled the same login/password on Gawker and the Playstation Network also recycled the same login for more important and personal logins too. You don’t want to be in that position.
