LulzSecurity (LulzSec), a group of hackers that recently gained notoriety for hacking PBS.org’s home page with an image of NyanCat, announced Thursday that it has stolen data from Sony. It’s yet another in a seemingly endless string of embarrassing security incidents for the company, but what’s shocking is just how exposed the data was to begin with.

In a press release posted to their Web site, LulzSec claims to have broken into SonyPictures.com and “compromised over 1,000,000 users’ personal information, including passwords, email addresses, home addresses, dates of birth, and all Sony opt-in data associated with their accounts.”

The theft included 75,000 “music codes” and 3.5 million “music coupons,” according to the group. LulzSec has posted segments of data they claim to have taken from Sony’s server to serve as proof of their accomplishment.
